Title: Discovery and monitoring of an environment using a plurality of robots
Inventor: SHANG Q GUO
IPC: G05D1/02
Filed: 2012-11-27
Abstract: A method and apparatus for navigating several robots is provided. A environment is discretised into several discrete regions, and a breadth-first search is used to determine a next unvisited region for one of the robots to explore. The robots may each determine the next unvisited region to explore, by taking a hypothetical step (510), in all directions, and maintaining a breadth-first search tree of paths until one declaring robot finds a next unvisited region (520). This declaring robot may then declare to other robots that an unvisited region has been found, and the other robots may then determine if there is a conflict between their planned paths and that of the declaring robot (540). The declaring robots search tree may then be collapsed to a single point corresponding to the found unvisited region (560). The search method may then repeat (570) until there are no regions left to explore (580).

The method comprises: accepting a 3-dimensional rendering of the mobile structure 102; accepting a specification of an inspection routine 104; determining a home position, relative to the structure, for the UAV 106; and generating a flight plan for the UAV 108, comprising instructions to visit points of the structure identified for inspection in the inspection routine. This application also discloses a method comprising: retrieving a flight plan for a UAV from a database; operating the UAV according to the flight plan; and using sensors equipped to the UAV to capture data indicative of various points for inspection on a mobile structure. The flight plan may include instructions for the UAV to capture video or image data of the structure.

Title: Smart display system
Inventor: Mohammed Shahzad Mughal
IPC: H04N7/18
Filed: 2017-07-31
Abstract: A smart display system comprises: an imaging device 3 such as a digital billboard, operable to capture an image; a multi-core image processing unit to process the captured image so as to determine features such as faces; and a display screen 1 to display an item of content such as an advertisement, tailored to be relevant to the determined features of the image. When the captured image shows people within the vicinity of the display screen and the features determined include features of these people the content can be tailored to the people in the vicinity. This allows for the content displayed on the smart display to be targeted towards a person or other features of an area, and therefore be more likely to be a successful advertisement. The image features may be recognized using pattern matching algorithms to match objects in an image library to features in the image. Metadata tags describing the determined features may be applied to the image.
