1. A video surveillance system, comprising:
- a first sensing unit having a substantially 360 degree field of view and adapted to detect an event in the field of view;
a communication medium connecting the first sensing unit and at least one second sensing unit, the at least one second sensing unit receiving commands from the first sensing unit to follow a target when an event of interest is detected by the first sensing unit wherein the first sensing unit comprises;
an omni-directional camera;
a video processing unit to receive video frames from the omni-directional camera; and
an event detection unit to receive target primitives from the video processing unit, to receive user rules to detect the event of interest based on the target primitives and the rules and to generate the commands for the second sensing unit.

Abstract
A method of operating a video surveillance system is provided. The video surveillance system including at least two sensing units. A first sensing unit having a substantially 360 degree field of view is used to detect an event of interest. Location information regarding a target is sent from the first sensing unit to at least one second sensing unit when an event of interest is detected by the first sensing unit.

13. A method of operating a video surveillance system, the video surveillance system including at least two sensing units, the method comprising:
- using a first sensing unit having a substantially 360 degree field of view detect an event in a field of view of the first sensing unit wherein the first sensing unit comprises an omni-directional camera;
sending location information regarding a target from the first sensing unit to at least one second sensing unit when an event is detected by the first sensing unit, automatically calibrating the omni-directional camera wherein the automatic calibration process comprises;
determining if a video frame from the omni-directional camera is valid;
performing edge detection to generate a binary edge image if the frame is valid;
performing circle detection based on the edge detection; and
creating a camera model for the omni-directional camera based on results of the edge detection and circle detection. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
