Abstract

A system and method for addressing video surveillance fields of view limitations. The system includes a first video camera that located at a first vantage point and a second video camera that is located at a second vantage point. A first lidar is located at the first vantage point and a second lidar is located at the second vantage point. A global positioning system is used to determine the global position of the first and second cameras and the first and second lidars. A processor receives data from the first camera, the second camera, the first lidar, the second lidar and the global positioning system. The processor creates a synthetic video image from any vantage point that is located between the first and second vantage points using the data from the first and second video cameras, the first and second lidars and the global positioning system.

Claims

1. A method of addressing video surveillance fields of view limitations, the method comprising:

loading a first video image of an area from a first vantage point into a database;

loading a second video image of the area from a second vantage point into the database;

loading a first set of data relating to the size and distance of objects in the area from the first vantage point into the database;

loading a second set data relating to the size and distance of the objects in the area from the second vantage point into the database;

loading a global position of the first vantage point and the second vantage point into the database; and

loading a global position of the objects in the area based on information in the database into the database; and

creating a synthetic video image of the area from a point that is located between the first vantage point and the second vantage point using information in the database.

2. The method of claim 1 wherein loading a global position of the first vantage point and the second vantage point into the database includes determining the global position of the first vantage point and determining the global position of the second vantage point.

3. The method of claim 2 wherein loading a global position of the objects in the area based on information in the database into the database includes determining the global position of the objects in the area based on information in the database.

4. The method of claim 2 wherein determining the global position of the first vantage point is done simultaneously with determining the global position of the second vantage point.

5. The method of claim 1 wherein loading a first video image of an area from a first vantage point into a database includes obtaining the first video image from a first camera, and loading a second video image of the area from a second vantage point into the database includes obtaining the second video image from a second camera.

6. The method of claim 5 wherein obtaining the first video image from the first camera is done simultaneously with obtaining the second video image from the second camera.

7. The method of claim 1 wherein loading a first set of data relating to the size and distance of objects in the area from the first vantage point into the database includes obtaining the first set of data from a first lidar, and loading a second set data relating to the size and distance of the objects in the area from the second vantage point into the database includes obtaining the second set of data from a second lidar.

8. The method of claim 7 wherein obtaining the first set of data from the first lidar is done simultaneously with obtaining the second set of data from the second lidar.

9. The method of claim 1 wherein loading a global position of the first vantage point and the second vantage point into the database includes determining the global position of the first vantage point and determining the global position of the second vantage point, and wherein loading a first video image of an area from a first vantage point into a database includes obtaining the first video image from a first camera, and loading a second video image of the area from a second vantage point into the database includes obtaining the second video image from a second camera, and wherein loading a first set of data relating to the size and distance of objects in the area from the first vantage point into the database includes obtaining the first set of data from a first lidar, and loading a second set data relating to the size and distance of the objects in the area from the second vantage point into the database includes obtaining the second set of data from a second lidar, and wherein determining the global position of the first vantage point includes receiving the global position of the first vantage point from a global positioning system that is located on the first lidar or the first camera and determining the global position of the second vantage point includes receiving the global position of the second vantage point from the global positioning system that is located on the second lidar or the second camera.

10. The method of claim 9 wherein obtaining the first video image from the first camera and obtaining the second video image from the second camera is done simultaneously with obtaining the first set of data from the first lidar and obtaining the second set of data from the second lidar which is also done simultaneously with receiving the global position of the first vantage point from the global positioning system and receiving the global position of the second vantage point from the global positioning system.

11. A video surveillance system comprising:

a first video camera located at a first vantage point;

a second video camera located at a second vantage point;

a first lidar located at the first vantage point;

a second lidar located at the second vantage point;

a global positioning system that detects the location of the first video camera, the second video camera, the first lidar and the second lidar; and

a processor that receives data from the first camera, the second camera, the first lidar, the second lidar and the global positioning system and creates a synthetic video image from a viewpoint that is located between the first vantage point and the second vantage point using the data.

12. The video surveillance system of claim 11 wherein the first camera is mounted on the first lidar and the second camera is mounted on the second lidar.

13. The video surveillance system of claim 11 further comprising a display that illustrates the synthetic video image generated by the processor.

14. The video surveillance system of claim 11 further comprising an input that allows a user to select the viewpoint of the synthetic video image.

15. The video surveillance system of claim 11 wherein the first video camera and the second video camera simultaneously send data to the processor.

16. The video surveillance system of claim 11 wherein the first lidar and the second lidar simultaneously send data to the processor.

17. The video surveillance system of claim 11 wherein the first lidar, the second lidar, the first video camera, the second video camera and the global positioning system simultaneously send data to the processor.

18. A video surveillance system comprising:

a first video camera located at a first vantage point;

a second video camera located at a second vantage point;

a first lidar located at the first vantage point;

a second lidar located at the second vantage point;

a global positioning system for detecting the location of the first video camera, the second video camera, the first lidar and the second lidar; and

a processor to receive data from the first camera, the second camera, the first lidar, the second lidar and the global positioning system to create a synthetic video image from a viewpoint that is located between the first vantage point and the second vantage point using the received data.

19. The video surveillance system of claim 18 wherein the first camera is mounted on the first lidar and the second camera is mounted on the second lidar, and wherein the first video camera and the second video camera each send data to the processor as the data is collected.

20. The video surveillance system of claim 19 further comprising:

a display to illustrate the synthetic video image generated by the processor; and

an input to facilitate selection of the viewpoint of the synthetic video image.
