The present application will now be described in greater detail by referring to the following discussion and drawings that accompany the present application. It is noted that the drawings of the present application are provided for illustrative purposes only and, as such, the drawings are not drawn to scale. It is also noted that like and corresponding elements are referred to by like reference numerals.
In the following description, numerous specific details are set forth, such as particular structures, components, materials, dimensions, processing steps and techniques, in order to provide an understanding of the various embodiments of the present application. However, it will be appreciated by one of ordinary skill in the art that the various embodiments of the present application may be practiced without these specific details. In other instances, well-known structures or processing steps have not been described in detail in order to avoid obscuring the present application.
It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.
Referring now to FIG. 1, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 1 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).
Referring now to FIG. 2, a set of functional abstraction layers provided by cloud computing environment 50 (FIG. 1) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 2 are intended to be illustrative only and embodiments of the invention are not limited thereto.

According to some embodiments and referring to FIG. 3, a method 300 includes a computing system determining a floor plan, locations of cameras in the environment and camera specifications for a given environment 301. Furthermore, at block 301 the determination of one or more of the floor plan, the camera locations, and the camera specifications can be performed as receiving setup data from a facilities management software product. According to some embodiments, the facilities management software product communicates with one or more devices (e.g., IoT) devices, providing insights to the environment. The cameras are connected to a video analytics software 302. At block 302, the cameras can be connected to a video management system. According to some embodiments, an initial calibration of the cameras is performed at block 302 using a homography or other geometric method for determining a relationship between images captured by the cameras. In the example of a homography, the homography relates different images of a same planar surface in the environment. According to at least one embodiment, camera rotation and translation can be extracted from a homography matrix and used for guiding navigation of the robot. The homography matrix is computed between different images of the environment captured by the cameras from different angles, such that the matrix contains a warped form of the images. The method includes provisioning one or more robots capable of navigating using a floor plan 303. For example, a robot uses specific geographic coordinates determined in 301 to navigate the floor plan. To facilitate camera calibration, the robot can include configuration graphics, for example, a geometric shape of known (to the computing system) dimensions. These graphics are detectable tokens visible in the scene, and can be printed on the robot or displayed by the robot. In some embodiments, the robot is shaped like a parallelepiped (i.e., a three-dimensional figure formed by six parallelograms) that mimics the height and width of a person (e.g., about 168 cm high by 38 cm wide). According to at least one embodiment, the robot includes an internal adjustable framework (or other mechanism) for configuring the dimensions of the parallelepiped. In some embodiments, one or more of the sides of the robot includes one or more detectable tokens (e.g., calibration grids, different colors, etc.), which can be used to distinguish the sides of the robot, determine an orientation of the robot, etc. According to some embodiments, one or more robots has a human-like shape. According to some embodiments, the computing system creates an object detection model configured to detect the robot 304. The model can be used by the computing system to detect one or more detectable tokens or features of the robot (e.g., the corners of the parallelepiped). According to one or more embodiments, the object detection model is configured to perform detection of objects, landmarks, etc. at 304. The object detection model can be configured as a deep-learning model, improving detection functionality through repeated detection tasks.
According to some embodiments and in view of the foregoing, blocks 301-304 represent an initial setup process.
According to some embodiments, a robot detection setup is performed at blocks [305-].
According to at least one embodiment, an object detection model is trained to detect the robot and some of its key landmarks (e.g., the corners of the parallelepiped) 305. For example, the object detection model can be trained using deep learning objection detection or a representative based metric learning method.
In another embodiment, the robot makes one or more initial tours of the environment 306. As the robot tours the environment it passes within and/or through a field of view of the cameras (referred to hereinafter as a scene), the computing system uses the model to detect the robot 307.
According to some embodiments, the detection 307 uses a background subtraction technique to detect the robot in the scene. In a case where the robot is the only moving object in the scene (e.g., the robot is deployed in an environment such as retail store after hours), the robot can be trivially isolated from the background. Otherwise, in a case where the scene includes other moving objects in addition to the robot, the robot can be differentiated from the other moving objects using postprocessing techniques, such as looking for sharp peaks that correspond to a known emitted color from the robot in a detected object color histogram. According to some embodiments, the computing system can communicate a control signal to the robot, causing the robot to update a current detectable token (e.g., a known pattern, color, combination of features, etc.) 308. For example, the detectable token can be dynamically calibrated according to a current scene, such that the robot can change the detectable token in a case where the computing system determines that the detectable token is too similar to other moving objects in the scene. For example, in a case where the computing system detects more than one detectable tokens, but expects to detect only one, the computing system can signal the robot to update the detectable token. In another example, the computing system can compare can the detectable token to the foreground, and in a case that the detectable token is close (e.g., based on a threshold).
According to some embodiments and referring to the method 400 of FIG. 4, given a set of colors C, video analytics software is used by the computing system S to analyze images of the scene from the camera(s), a communication pipeline between the robot and S, x=1, the update of the detectable token 308 can include emitting color Cx by the robot 401, computing system S detects all moving objects in the scene and generates color histograms H for each object 402, the computing system S detects a number of moving objects P with sharp peaks of Cx in H 403, and at 404 the computing system determines if the robot is unique. For example, if P=1 (i.e., only the robot emits color Cx), keep the color, sleep N time; else if P>2, x=x+1 and send new color Cx to robot 405. The method 308 can be performed iteratively.
As the robot is detected in the scene during its tour 306-307, it is cropped from the current image and each cropped image is saved in a database 309. Once N sample images of the robot are saved, the setup tour ends 310. According to some embodiments, the sample images are then used to train a robot detection model 311. According to at least one embodiment, the training of the robot detection model uses traditional techniques, such as deep learning objection detection or a representative based metric learning method.
According to some embodiment and referring to FIG. 5, a camera calibration and configuration method 500 includes, for each camera making an initial estimate of the camera's scene, projected onto the floor plan, as a geo-polygon 501 using the camera specifications and the floor plan, (see computer vision book in the prior art for method). The method includes the robot to navigating the geo-polygon 502. The robot navigation can be controlled by the computing system or operate autonomously, for example, using geo-localization and the floor plan. The method includes detecting when the robot enters and leaves a scene of the camera 503 using the robot detection deep-learning model. At block 504 the method includes performing time synchronization between deep-learning inference data and geo-localization data sent by the robot. According to some embodiments, the system uses two data sources including coordinates (e.g., GPS coordinates) received from the robot and a video stream received from the camera, and these data sources are time synchronized to improve an accuracy of detection results and generated models, for example, so that an exact time an alert is generated can be compared to an appearance of the robot in an image (e.g., is the robot fully in the scene, entering and partially in the scene, exiting the scene and still partially visible, etc.). The method includes mapping at least one point in the camera's scene to the geo-coordinates of the robot, which can be translated into a position within the geo-polygons 505, which enables users to select a point on a video stream of the camera and send a robot to that location. At block 506 data about the scene of the camera are recorded, which enable the discovery of blind angles and reposition the cameras. Data about the detected robot landmarks are recorded 507 with the robot occupying various positions in the scene. Using a geometric method, such as a homography, the recorded data (i.e., detected and recorded robot landmarks) can be used to calibrate the camera. Alerts are configured at block 508. To configure alerts 508 that involve regions of interest/uninterest or virtual tripwires, a user draws a polygon or line on a digital representation/display of the floor plan, and the geometric shape is mapped to the geo-coordinates, which enables the robot to move along the edges of the geo-polygon, while the video analytics detects the robot and captures trajectories, where captured trajectories are used as the representation of the region of interest (ROI) on the video stream. The use of a human-shaped robot is helpful in this case. To configure alerts 508 (that can be executed/triggered by the computing system) that involve a minimum and/or maximum number of pixels, the robot crisscrosses a region of interest, the video analytics detects the robot and calculates its size in pixels, minimum and maximum sizes are calculated across the region of interest. If the robot dimensions are not equal (e.g., depth<width), the robot may crisscross the region of interest multiple times in different directions. Being able to modify the dimensions of the robot (e.g., using the adjustable framework) can be helpful in this case. If the dimensions of the robot are known, the dimensions can be extrapolated to a minimum and maximum dimension for other objects that need to navigate the environment (e.g., a person). In particular environments, these dimensions can be further constrained by the known dimensions of the objects that are expected to appear in the images captured by camera.
According to some embodiments, the computing system generates camera positioning suggestions. If a region of interest or a virtual tripwire is partly outside of the scene, an alert is generated and a camera positioning adjustment is recommended. The position of cameras, even static ones, can change. By periodically re-running the calibration steps (see FIG. 5), the computing system can detect if a camera has moved (e.g., by comparing a point in the camera's scene to geo-coordinates). Upon detecting a change (e.g., greater than a threshold, such a 2 degrees of arc), the computing system can issue an alert to a user.
FIG. 7 shows a User Interface (UI) 700 enabling camera calibration according to some embodiments of the present invention. The UI includes a configuration window 701 enabling a user to move the edges, e.g., 702, or vertices, e.g., 703, of a bounding box (e.g., by drag-and-drop) to configure camera perspectives. The UI includes a visualization window 704, in which detected objects (e.g., in an augmented view including box(es) 705 around the detected object) and their vectors (e.g., see vector 706).
According to some embodiments and referring to FIG. 6, an automatic testing method 600 includes providing a robot with a human-like shape 601 and using the robot in testing the computing system, including the video analytics. The human-like shape is detectable as a person by the deep-learning detection model used in the video analytics pipeline. For each video analytics alert definition 602, the robot is instructed to navigate to a corresponding region of interest 603 (a region that is monitored and in which certain activity will trigger the alert), and an exact context and location is determined where an alert condition(s) is/are satisfied (e.g., minimum or maximum size, direction, speed, etc.) by the robot 604, where the computing system can verify whether an alert is triggered 605. According to some embodiments, the robot is controlled to mimic the behavior of a human in the region of interest, the mimicked behavior being configured to trigger one or more alert conditions. For example, the robot can be controlled to pass through the region of interest at a speed that triggers an alert condition associated with a running human. In a case where the alert is not triggered by the robot, additional training data is generated with automatic annotation 606. By iterating through the video analytics alert definitions, the computing system can capture images of the robot 607 in various locations, various positions, and various dimensions, and use a homography to automatically generate a bounding box around the robot 608. For example, at 608, given the geocoordinates of the robot and its physical dimensions, and the homography defined while calibrating the cameras is applied to extract pixel coordinates of the robot in the images captured by the camera. These pixel coordinates, together with the camera images, constitute new training data.
According to some embodiments, at blocks 606-608 of FIG. 6, if an alert is not triggered when the robot reproduces the alert condition, the detection model has failed to detect the robot. Such a failure will indicate that additional training data is needed to re-train the model. The additional training data can include an image capture of the scene provided with a bounding box identifying the location of the region of interest within the environment in which the robot should have been detected by the model in the earlier iteration.
It should be understood that bounding boxes can be stored as a set of coordinates bounding a detected object. It can be useful, for performance reasons, to choose a bounding box that is as small as possible around the detected object.
FIG. 8 shows a UI 800 enabling alert configuration according to some embodiments of the present invention. The UI includes a list of alerts 801, and a set of controls for creating and modifying each alert. The controls include, for example, parameters 802, schedule 803 (e.g., for setting a time that the alerts are active), responses 804 (e.g., for configuring text alerts, audio alerts, controlling IoT devices, for example, to control lighting, locking/unlocking doors, etc.). Each tab (e.g., 802-804) can reveal include controls to adjusting various features thereof. The UI includes a visualization window 805, in which a bounding box(es) 806, virtual tripwires, etc. can be set for the current alert selected in the list of alerts 801.
FIG. 9 shows a computing system 901 including a plurality of connected cameras, e.g., 902, where the computing system and cameras are connected by a network 903, for example, including ethernet connections, wireless connections, coaxial cable, etc. The computing system 901 includes software modules 904, such as the video analytics pipeline, and storage facilities 905 (e.g., memory, local database, cloud storage, etc.). The video analytics pipeline includes to the learning model 906, the object detection model 907, etc., which are stored in memory 905 of the computing system 901. One or more cameras can include motion control servos 908 for adjusting the field of view. The network 903 further connects the computing system 901 to IoT devices 909, which are receive signals corresponding to alerts, etc. The computing system 901 is further connected to one or more robots, 909, for example, by Bluetooth or other wireless communications functionality.
According to some embodiments of the present invention, the detection method uses a background subtraction process. The background subtraction process includes a background initialization including providing an initial background image of the environment, classifying pixels in a subsequent image(s) captured by at least one of the cameras as foreground or background by comparing the background image and the subsequent image(s), and updating the background image by using the previous background, the subsequent image(s), and a foreground detection mask. This process is repeated a number of times, with the detection method improving each iteration, e.g., by deep-learning.

Computer system/server 12 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 34 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus 18 by one or more data media interfaces. As will be further depicted and described below, memory 28 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.
Program/utility 40, having a set (at least one) of program modules 42, may be stored in memory 28 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules 42 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.
Computer system/server 12 may also communicate with one or more external devices 14 such as a keyboard, a pointing device, a display 24, etc.; one or more devices that enable a user to interact with computer system/server 12; and/or any devices (e.g., network card, modem, etc.) that enable computer system/server 12 to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces 22. Still yet, computer system/server 12 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 20. As depicted, network adapter 20 communicates with the other components of computer system/server 12 via bus 18. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server 12. Examples, include, but are not limited to: microcode, device drivers, redundant processing units, and external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.
Thus, one or more embodiments can make use of software running on a general purpose computer or workstation. With reference to FIG. 10, such an implementation might employ, for example, a processor 16, a memory 28, and an input/output interface 22 to a display 24 and external device(s) 14 such as a keyboard, a pointing device, or the like. The term “processor” as used herein is intended to include any processing device, such as, for example, one that includes a CPU (central processing unit) and/or other forms of processing circuitry. Further, the term “processor” may refer to more than one individual processor. The term “memory” is intended to include memory associated with a processor or CPU, such as, for example, RAM (random access memory) 30, ROM (read only memory), a fixed memory device (for example, hard drive 34), a removable memory device (for example, diskette), a flash memory and the like. In addition, the phrase “input/output interface” as used herein, is intended to contemplate an interface to, for example, one or more mechanisms for inputting data to the processing unit (for example, mouse), and one or more mechanisms for providing results associated with the processing unit (for example, printer). The processor 16, memory 28, and input/output interface 22 can be interconnected, for example, via bus 18 as part of a data processing unit 12. Suitable interconnections, for example via bus 18, can also be provided to a network interface 20, such as a network card, which can be provided to interface with a computer network, and to a media interface, such as a diskette or CD-ROM drive, which can be provided to interface with suitable media.
Accordingly, computer software including instructions or code for performing the methodologies of the invention, as described herein, may be stored in one or more of the associated memory devices (for example, ROM, fixed or removable memory) and, when ready to be utilized, loaded in part or in whole (for example, into RAM) and implemented by a CPU. Such software could include, but is not limited to, firmware, resident software, microcode, and the like.
A data processing system suitable for storing and/or executing program code will include at least one processor 16 coupled directly or indirectly to memory elements 28 through a system bus 18. The memory elements can include local memory employed during actual implementation of the program code, bulk storage, and cache memories 32 which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during implementation.
Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, and the like) can be coupled to the system either directly or through intervening I/O controllers.
Network adapters 20 may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modem and Ethernet cards are just a few of the currently available types of network adapters.
As used herein, including the claims, a “server” includes a physical data processing system (for example, system 12 as shown in FIG. 10) running a server program. It will be understood that such a physical server may or may not include a display and keyboard.
One or more embodiments can be at least partially implemented in the context of a cloud or virtual machine environment, although this is exemplary and non-limiting. Reference is made back to FIGS. 1-2 and accompanying text. Consider, e.g., a database app in layer 66.
It should be noted that any of the methods described herein can include an additional step of providing a system comprising distinct software modules embodied on a computer readable storage medium; the modules can include, for example, any or all of the appropriate elements depicted in the block diagrams and/or described herein; by way of example and not limitation, any one, some or all of the modules/blocks and or sub-modules/sub-blocks described. The method steps can then be carried out using the distinct software modules and/or sub-modules of the system, as described above, executing on one or more hardware processors such as 16. Further, a computer program product can include a computer-readable storage medium with code adapted to be implemented to carry out one or more method steps described herein, including the provision of the system with the distinct software modules.
One example of user interface that could be employed in some cases is hypertext markup language (HTML) code served out by a server or the like, to a browser of a computing device of a user. The HTML is parsed by the browser on the user's computing device to create a graphical user interface (GUI).
