Abstract

The embodiment of the invention provides a video monitoring method, a video monitoring device and a video monitoring system, aiming at solving the problem that in the prior art, video tracking interruption or error is caused by an excessively fixed feature information extraction method. The video monitoring method comprises the steps of tracking the movement of a target object by video, and extracting and storing at least one feature information of the target object; the method further comprises the steps of comparing the video tracking image of the current frame with that of the previous frame; when the at least one feature information of the target object in the video tracking image of the current frame changes relative to that of the previous frame, further extracting and storing the changed at least one feature information.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a video monitoring method, device and system. technical background [0002] In the video surveillance of the prior art, when the video surveillance area is large, the feature information of the target object must be extracted first, and then the acquired feature information is exchanged between the cameras to complete the continuous identification and tracking of the target object. The feature information extraction method in the prior art is relatively fixed, such as continuously identifying the extracted license plate information or face information. [0003] However, since the feature information of the target object itself also changes, continuous attempts to obtain the original feature information of the target object will lead to interruption and error in tracking the target object. For example, when a person's face information is continuously tracked, once the person's fac...
