Method and apparatus for monitoring macro range of environment based on reference frames comparison

摘要

A method and an apparatus for monitoring macro environment, which achieves a real-time monitoring of a macro environment through retrieving the macro environment into more than one reference frame and comparing them with a retrieving frame by utilizing a video-retrieving device of a computer (PC camera). When the variations of the retrieving frame relative to the reference frames are beyond a preset threshold value of variation rate, the computer sends out a controlling signal to control the actuation of an alerting device, storing device or network communication device, etc. Through the monitoring method, the problem of view angle limitation existing in previous video-retrieving devices can be effectively resolved, and the real-time monitoring of a macro environment can be performed.
