Abstract

The invention discloses front-end equipment in a video monitor system, a video monitor system, and a signal processing method in the front-end equipment. Moving objects in a monitored scene represented by digital video signals are detected and tracked at the same time of acquiring the digital video signals, and the tracking data is analyzed to obtain a result of whether or not to send an alarm, thereby achieving intelligent analysis while achieving video monitor. For the video monitor system and the front-end equipment, a moving object detection and tracking module and an intelligent video analysis module can be embedded in the hardware of the front-end equipment in the software manner so as to facilitate the function expansion and updating of the video monitor system..

Description

technical field

[0001] The invention relates to video monitoring technology, in particular to a front-end device in a video monitoring system, a video monitoring system, and a signal processing method in the front-end device. Background technique

[0002] The intelligence of the video surveillance system is an inevitable requirement for the development of surveillance equipment. However, due to the functional and performance limitations of the front-end equipment in various existing video surveillance systems, it is impossible to realize intelligent video surveillance. Therefore, when an accident occurs in the surveillance scene, there are usually long alarm response times, False and missed reports, judging whether an accident occurred based on video playback, and difficulty in analyzing video recording data. Contents of the invention

[0003] In view of this, the present invention provides a front-end device in a video surveillance system, a video surveillance system, an...
