Abstract

A panoramic image management system and method is disclosed. The system provides for improved calibration of a 360 degree panoramic camera, as well as improved means for manipulating the images, and correlating images from conventional video cameras with the images from the 360 degree panoramic camera. The system also provides means for archiving and retrieving stored images. The present invention contributes to an improved video surveillance system.

Claims

1. A system for displaying video from a 360 degree panoramic video camera that comprises a convex reflector and an image capture element, comprising:

a first display window showing the video from the 360 degree panoramic video camera in a circular video view;

means for converting the video from the circular video view into a rectangular format;

a second display window showing the video from the 360 degree panoramic video camera in a rectangular video view;

means for indicating an offset between the center of the convex reflector, and the center of the image capture element; and

means for reconverting the video from the circular video view into rectangular format based on said offset, thereby providing a dewarped rectangular video view.

2. The system of claim 1, further comprising:

means for establishing a positional shift; and

a third display window, wherein said third display window displays the video from the second display window with the positional shift applied thereto.

3. The system of claim 2, wherein the means for establishing the positional shift comprises moving the video in the third display window to a desired positional shift via a pointing device.

4. The system of claim 3, further comprising:

means for resetting the positional shift to zero; and

means for displaying the video in the third display window with the positional shift of zero.

5. The system of claim 4, further comprising means for inverting the video in the third display window.

6. The system of claim 5, further comprising means for archiving video in a plurality of temporally sorted capture files.

7. The system of claim 6, further comprising means of retrieving a capture file based on a user-entered date and time.

8. The system of claim 2, further comprising means for magnifying a portion of the rectangular video view.

9. The system of claim 2, further comprising means for aiming a plurality of conventional cameras at a location indicated by coordinates on the rectangular video view.

10. The system of claim 9, wherein the means for aiming a plurality of conventional cameras at a location indicated by a position on the rectangular video view comprises:

a plurality of conventional cameras, each conventional camera comprising a controllable, angularly adjustable camera mount;

a user interface configured to indicate the position on the rectangular video view; and

a PTZ controller, configured to receive the position from the user interface, calculate angular information for each conventional camera, and transmit said angular information to each camera mount.

11. The system of claim 10, further comprising means for displaying images from the plurality of conventional cameras simultaneously with the rectangular video view.

12. The system of claim 1, wherein the 360 degree panoramic video camera further comprises a retractable housing, and means for extending and retracting said housing.

13. The system of claim 2, further comprising means for creating and saving a still image from the rectangular video view.

14. The system of claim 2, further comprising means for selecting an input source for the 360 degree panoramic video camera, wherein the input source is selected from the group consisting of USB, IEEE-1394, and network.

15. A method of calibrating a 360 degree panoramic video camera that comprises a convex reflector and an image capture element, comprising the steps of:

positioning a cursor to a desired position on a user interface; and

selecting a desired position via pressing a button on a pointing device;

wherein the desired position is indicative of an offset between the center of the convex reflector, and the center of the image capture element;

storing said offset in a non-volatile storage location; and

reconverting the video from a circular video view into rectangular format based on said offset.
