Audio and video conjoint analysis-based fighting detection system and detection method thereof

Abstract

The invention discloses an audio and video conjoint analysis-based fighting detection system and an audio and video conjoint analysis-based fighting detection method thereof. The audio and video conjoint analysis-based fighting detection system comprises a video acquisition module, an audio acquisition module, an algorithm detection module and a management module, wherein each of the video acquisition module and the audio acquisition module adopts a camera, an acquisition card and a computer; the video acquisition module acquires an analogue signal of the camera to a memory of the computer by the acquisition card; the audio acquisition module acquires the analogue signal of the camera to the memory of the computer by the acquisition card; and the algorithm detection module judges the fighting of persons in a target area, judges synchronous audio and video, detects, identifies and positions the chaotic fighting of the persons in the target area, and outputs results to the management module. In the system and the method, the behaviors of the persons in a monitored scene are analyzed, identified and positioned to accurately diagnose the abnormal behaviors such as gathering, fighting and the like of the persons appearing in a video image and give an alarm.

Description

technical field [0001] The invention relates to a fight detection system, in particular to a fight detection system and a detection method for joint analysis of audio and video. Background technique [0002] Fighting and fighting incidents are socially unacceptable violations of law and discipline, which have a negative impact on social stability and people's lives. As for the handling of fighting incidents, at present, the main method is to notify the police after the incident. It is difficult for the public security organs to obtain the alarm information in the first time, and it is also difficult to obtain evidence in the first time, which brings difficulties for subsequent investigations. For the fight analysis of the monitoring system, because only the information of the video is used, it is difficult to make an accurate judgment on the fight. Fighting to distinguish, will produce more false alarms. Contents of the invention [0003] The technical problem to be solv...
