METHOD AND SYSTEM FOR AUTONOMOUS VIDEO MONITORING
First Claim
1. A method for autonomous monitoring comprising:
- collecting video signals of a region to be monitored by an video signal collecting module;
analyzing a current image and a previous image of the region to be monitored from the video signals by an image processing module;
calculating a number of points of difference between the current image and the previous image by an image comparison module;
wherein the image comparison module stores a predetermined threshold value of different points and is capable of outputting an alarm signal when the number of different points exceeds the predetermined threshold value; and
indicating an alarm condition when receives the alarm signal by an alarm module.

Abstract
A method for autonomous monitoring includes the following steps. A plurality of video signals of a region to be monitored is collected by a video signal collecting module. A current image and a previous image of the region to be monitored are analyzed by an image processing module. A number of points of difference between the current image and the previous image is calculated by an image comparison module. The image comparison module stores a predetermined threshold value of different points and is capable of outputting an alarm signal when the number of different points exceeds the predetermined threshold value. An alarm condition is indicated by an alarm module when the alarm signal is received.
