Abstract

In V2V or other networks in which multiple video cameras can share video data, a user may elect to modify a primary view by electronically “removing” obstructing objects from the primary view. The user begins by identifying the objects to be electronically removed from the simulated view, either by designating the boundaries of the objects or by identifying classes of objects to be removed. Pel locations associated with obstructing objects are identified in the primary data set. Video data provided by cameras other than a primary video camera is analyzed to identify common features in the primary and secondary views and to identify pels that correspond with object-associated pels in the primary view. A merged data set, consisting of pel data from the primary data set and from at least one of the secondary data sets, provides the video data presented in the simulated view.

Claims

1. A method of generating a view for presentation on a video display comprising:

receiving a primary set of video data from a first video camera;

receiving user input designating an object to be excluded from the view presented on the video display;

receiving a secondary set of video data from a video camera other than the first video camera;

associating data elements in said received secondary set of video data with data elements in said primary set of video data representing an object designated to be excluded from the view presented on the video display;

generating a set of video data comprising video data from said primary set and said associated data elements in said received secondary set; and

displaying the generated set of video data on the video display.

2. A method according to claim 1 wherein each of the video cameras is mounted on a vehicle.

3. A method according to claim 2 further comprising modifying the generated set of video data to include a visible reminder that an object is excluded from the view that would have been presented by the primary set of video data.

4. A method according to claim 3 wherein the included visible reminder comprises a wire form representation of the excluded object.

5. A method according to claim 2 wherein receiving user input designating at least one object to be excluded from the view presented on the video display further comprises receiving the user input designating boundaries of the object to be excluded.

6. A method according to claim 5 wherein receiving the user input designating boundaries of the object to be excluded further comprises using an expandable bounding box to designate the boundaries.

7. A method according to claim 2 wherein receiving user input designating at least one object to be excluded further comprises receiving information designating a class of objects to be excluded from the view.

8. A system comprising a video display and a controller for generating of view to be presented on said video display, said controller comprising:

a first video input system for receiving a primary set of video data from a first video camera;

a user interface system for receiving a user input designating at least one object to be excluded from the view presented on a video display;

a second video input system for receiving a secondary set of video data from a video camera other than the first video camera;

video processing logic for associating data elements in said received secondary set of video data with data elements in said received primary set of video data representing an object designated to be excluded from the view presented on the video display;

video combining logic for generating a set of video data comprising video data from said primary set and said associated data elements in said received secondary set; and

video driver logic for displaying the generated set of video data on the video display.

10. A system according to claim 8 wherein each of said video cameras is mounted on a vehicle.

11. A system according to claim 10 wherein said video combining logic further comprises logic for modifying the generated set of video data to include a visible reminder that an object is excluded from the view that would have been presented by the primary set of video data.

12. A system according to claim 11 wherein the included visible reminder comprises a wire form representation of the excluded object.

13. A system according to claim 10 wherein said user interface system further comprises means for receiving user input designating boundaries of the object to be excluded.

14. A computer program product for generating a view for presentation on a video display, said computer program product comprising a computer usable medium having computer usable program code embodied therewith, said computer usable program code comprising:

computer usable program code configured to receive a primary set of video data from a first video camera;

computer usable program code configured to receive user input designating at least one object to be excluded from the view presented on the video display;

computer usable program code configured to receive a secondary set of video data from a video camera other than the first video camera;

computer usable program code configured to associate data elements in said received secondary set of video data with data elements in said received primary set of video data representing an object designated to be excluded from the view presented on the video display;

computer usable program code configured to generate a set of video data comprising video data from said primary set and said associated data elements in said received secondary set; and

computer usable program code configured to display the generated set of video data on the video display.

15. A computer program product according to claim 14 wherein each of the video cameras is mounted on a vehicle.

16. A computer program product according to claim 15 further comprising computer usable program code configured to modify the generated set of video data to include a visible reminder that an object is excluded from the view that would have been presented by the primary set of video data.

17. A computer program product according to claim 16 wherein the included visible reminder comprises a wire form representation of the excluded object.

18. A computer program product according to claim 15 wherein said computer usable program code configured to receive user input designating at least one object to be excluded from the view presented on the video display further comprises computer usable program code configured to receive user input designating boundaries of the object to be excluded.

19. A computer program product according to claim 18 wherein said computer usable program code configured to receive user input designating boundaries of the object to be excluded further comprises computer usable program code configured to receive user input designating an expandable bounding box.

20. A computer program product according to claim 15 wherein said computer usable program code configured to receive user input designating at least one object to be excluded from the view presented on the video display further comprising computer usable program code configured to receive user input designating a class of objects to be excluded from the view.
