DETAILED DESCRIPTION OF ILLUSTRATIVE VARIATIONS
The following description of the variations within the scope of the invention is merely illustrative in nature and is in no way intended to limit the scope of the invention, its application, or uses.
A number of illustrative variations are fully or partially illustrated in FIGS. 1a, 1b, 2a, 2b, and 2c. A number of variations may involve the situation in which a vehicle 12 has pulled out of a familiar parking space 10 by a sufficient distance from where it was previously backed in and parked, for example, as shown in the non-limiting illustration of FIG. 1a. A first image 20 of the familiar parking space is created by imaging hardware 11 and a space that the vehicle 12 is expected to occupy after backing up is overlaid onto the first image 20. For purposes of this illustrative variation, this overlay is referred to as the vehicle path 13. This first image 20 is then stored in a storage device 16. When the vehicle is to be returned and backed into its former, familiar parking space 10, the imaging hardware 11 once again creates an image of the familiar parking space 10 such that the perspective of the first and second images are sufficient for comparison, for example, as shown in the non-limiting illustration of FIG. 1b. This second image 30 is then matched to the first image 20 such that the vehicle path 13 which was overlaid on the first image 20 can be reasonably correlated to the second picture. A controller 14 which may be aboard the vehicle then compares the second image 30 to the first image 20 in order to determine whether there is an object 15 in the vehicle path 13. If there is at least one object 15 in the vehicle path 13, a notification 17 is produced by the vehicle.
In another illustrative variation which also involves the situation in which a vehicle 12 has pulled out of a familiar parking space 10, such as a homeowner's garage, by a sufficient distance from where it was previously backed in and parked. Several first images 20 of the familiar parking space 10 are created by imaging hardware 11 aboard the vehicle at several angles and distances as the vehicle 12 moves away from the familiar parking space 10, thereby obtaining several first images 20 having multiple perspectives of the familiar parking space 10. A space where the vehicle may be parked in the familiar space is overlaid on each of the first images 20, for example, as illustrated in FIG. 2a. For purposes of this illustrative variation, these overlays are referred to as the vehicle path 13. At least one of the first images 20 is then stored in a storage device 16 which may be onboard the vehicle 12. Alternatively, the first images 20 may be stored at a remote location such as, but not limited to, a cloud server accessible by telecommunication devices onboard the vehicle. When the vehicle's position and movement indicate that the vehicle 12 is backing into the familiar parking space 10 or that the vehicle 12 is in substantially the same position where the first images 20 were created, the imaging hardware 11 aboard the vehicle 12 automatically and continuously creates a set of second images 30 of the familiar parking space 10, for example as illustrated in FIG. 2b. These second images 30 are then continuously correlated to the first images 20 and corrected for displacement, such that a vehicle path 13 which has been overlaid on at least one of the first images 20 can be reasonably correlated to at least one of the second images 30. A controller 14 actively compares the second images 30 to the first images 20 in order to determine whether there is an object 15 in the vehicle path 13. If there is at least one object 15 in the vehicle path 13 and there is a display screen which is in communication with the controller 14, the at least one object 15 may be highlighted on the display screen and displayed to the pilot of the vehicle 12 and may be accompanied by audible, physical or other sensory notifications 17 of the same, for example as illustrated in FIG. 2c. In a number of illustrative variations, a first and/or second amount of image data may be produced in lieu of a first and/or second image or in addition to a first and/or second image. The vehicle path 13 may be represented within the first and/or second amount of image data as well as the first and/or second image.
In a number of illustrative variations, the imaging hardware 11 may be induced to create an image and/or image data in light of vehicle 12 position and/or movement and/or position and/or movement data. Imaging hardware 11 may include but is not limited to devices which utilize radar, ultrasonic imaging, light detection and ranging, photographs and other types of optical and acoustic sensing which are known in the art. All of these imaging hardware devices may be used in stereo or higher multiplicities and also as solo devices for imaging and sensing. These devices may produce images and/or image data including but not limited to image depth information, color, and/or heat information. Light sensitive imaging hardware may also use night vision technology and/or other vision aiding or amplifying devices. Any image or image data produced by the imaging hardware 11 may be subject to filtering and/or processing and/or modification of any type by a controller 14.
In a number of non-limiting illustrative variations, a depth map may be correlated to an image as show in FIG. 3.
A number of illustrative variations include a storage device 16 which may be aboard the vehicle 12 and which is capable of storing at least one image and/or image data. This storage device 16 may store an image and/or image data on a storage medium of a magnetic type, optical type, semiconductor type and/or any other type which is known in the art.
In a number of illustrative variations include a method of expressing a notification 17 which is able to be sensed. This notification 17 may be of the visible type, audible type, physical type and/or any type which may be sensed by living organism or inanimate sensor. This notification 17 may be expressed according to its sensory focus by a display screen, speakers, gyrating or vibrating motors or any number of methods and/or products which may be used to produce an output that may be sensed.
