Abstract

Tracking an intruder throughout regions in an area under surveillance by locating video cameras to provide an image for each region. For each camera a subset of the cameras are associated as auxiliary cameras to that camera; these associations are stored in a table. One camera is the initial primary camera and displays an initial primary image. An auxiliary video image is displayed for each of the auxiliary cameras that were previously associated with the initial primary camera. An intruder travels from region to region and leaves the primary video image and/or appears in an auxiliary video image. The user selects one of the auxiliary cameras to become a subsequent primary camera, and the video image from the subsequent primary camera is displayed as a subequent primary image. A video image for each of the auxiliary cameras previously associated with the subsequent primary camera will be displayed.

Claims

1. A method of tracking an object of interest throughout an area under surveillance comprising a plurality of regions, said method comprising:

a. locating a plurality of video cameras so as to provide a video image associated with each of said regions;

b. for each of said video cameras as a primary video camera, associating a subset of said plurality of video cameras as auxiliary video cameras to said primary video camera;

c. selecting one of said video cameras as an initial primary video camera to display a video image therefrom as an initial primary video image;

d. displaying an auxiliary video image for each of the subset of auxiliary video cameras previously associated with said initial primary video camera;

e. selecting one of said auxiliary video cameras to become a subsequent primary video camera;

f. displaying the video image from the subsequent primary video camera as a subequent primary video image;

g. displaying a video image for each of the subset of auxiliary video cameras previously associated with said subsequent primary video camera.

3. The method of claim 1 wherein all of the video images are displayed on a single computer monitor.

4. The method of claim 3 wherein the video images are displayed in a matrix format with the primary video images being displayed in the center and the auxiliary video images displayed in a pattern surrounding the primary video image.

5. The method of claim 1 wherein the step of selecting one of said auxiliary video cameras to become a subsequent primary video camera comprises grabbing the auxiliary video image associated with the desired auxiliary video camera with a computer mouse and then draging the grabbed auxiliary video image to overlap the primary video image.

6. The method of claim 1 wherein the step of selecting one of said auxiliary video cameras to become a subsequent primary video camera comprises clicking on the auxiliary video image associated with the desired auxiliary video camera with a computer mouse.

7. The method of claim 1 wherein said auxiliary video images comprise a zoom image, a wide angle image, or a pan image.

2. The method of claim 2 further comprising repeating steps e, f, and g as desired.

8. A video surveillance system for tracking an object of interest throughout an area under surveillance comprising a plurality of regions, said system comprising:

a. a plurality of video cameras strategically located so as to provide a video image associated with each of said regions; and

b. a video controller interconnected with the plurality of video cameras, comprising;

i. memory adapted to store a table of associations of;

for each of said video cameras as a primary video camera, a subset of said plurality of video cameras as auxiliary video cameras associated with said primary video camera;

ii. an input device that enables the selection of one of said video cameras as an initial primary video camera to display a video image therefrom as an initial primary video image;

iii. a display device that provides for the displaying of the initial primary video image and an auxiliary video image for each of the subset of auxiliary video cameras previously associated with said initial primary video camera;

iv. wherein the input device further enables the selection of one of said auxiliary video cameras to become a subsequent primary video camera;

v. wherein the display further displays the video image from the subsequent primary video camera as a subequent primary video image;

vi. wherein the display further displays a video image for each of the subset of auxiliary video cameras previously associated with said subsequent primary video camera; and

vii. processing circuitry adapted to control the operation of the memory, the input device, and the display accordingly.

9. The system of claim 8 wherein all of the video images are displayed on a single computer monitor.

10. The system of claim 9 wherein the video images are displayed in a matrix format with the primary video images being displayed in the center and the auxiliary video images displayed in a pattern surrounding the primary video image.

11. The system of claim 8 wherein the input device is a computer mouse that enables the grabbing of the auxiliary video image associated with the desired auxiliary video camera and then draging the grabbed auxiliary video image to overlap the primary video image.

12. The system of claim 8 wherein the input device is a computer mouse that enables the clicking on the auxiliary video image associated with the desired auxiliary video camera.

13. The system of claim 8 wherein said auxiliary video images comprise a zoom image, a wide angle image, or a pan image.

14. A video controller for use in a video surveillance system for tracking an object of interest throughout an area under surveillance comprising a plurality of regions, the video controller being interoperable with a plurality of video cameras strategically located so as to provide a video image associated with each of said regions said system, the video controller comprising:

i. memory adapted to store a table of associations of;

for each of said video cameras as a primary video camera, a subset of said plurality of video cameras as auxiliary video cameras associated with said primary video camera;

ii. an input device that enables the selection of one of said video cameras as an initial primary video camera to display a video image therefrom as an initial primary video image;

iii. a display device that provides for the displaying of the initial primary video image and an auxiliary video image for each of the subset of auxiliary video cameras previously associated with said initial primary video camera;

iv. wherein the input device further enables the selection of one of said auxiliary video cameras to become a subsequent primary video camera;

v. wherein the display further displays the video image from the subsequent primary video camera as a subequent primary video image;

vi. wherein the display further displays a video image for each of the subset of auxiliary video cameras previously associated with said subsequent primary video camera; and

vii. processing circuitry adapted to control the operation of the memory, the input device, and the display accordingly.

15. The video controller of claim 14 wherein all of the video images are displayed on a single computer monitor.

16. The video controller of claim 15 wherein the video images are displayed in a matrix format with the primary video images being displayed in the center and the auxiliary video images displayed in a pattern surrounding the primary video image.

17. The video controller of claim 14 wherein the input device is a computer mouse that enables the grabbing of the auxiliary video image associated with the desired auxiliary video camera and then draging the grabbed auxiliary video image to overlap the primary video image.

18. The video controller of claim 14 wherein the input device is a computer mouse that enables the clicking on the auxiliary video image associated with the desired auxiliary video camera.

19. The video controller of claim 14 wherein said auxiliary video images comprise a zoom image, a wide angle image, or a pan image.
