Abstract

The invention discloses a method for automatically recognizing an abnormal velocity event in a surveillance video. The method comprises the steps that (1) frame images are read from the monitoring video, image processing is conducted, and therefore a needed image sequence is obtained; (2) a statistical average method and mixture Gaussians background modeling are adopted to establish a background model, and a background differencing method is used for detecting a foreground target set; (3) a cross matching detecting method and a Mean-shift algorithm are combined for tracking a moving target corresponding to each foreground target in the foreground target set so as to obtain the position information of each moving target; (4) the speed of each moving target is calculated, and when the speed of each moving target exceeds a preset threshold, an alarm is given out; otherwise, the step (1) is executed. By the adoption of the method for automatically recognizing the abnormal velocity accident in the monitoring video, foreground targets corresponding to moving targets can be accurately detected, the foreground targets are used for guaranteeing that the positions of the moving targets do not deviate to the largest degree, and the abnormal velocity accident can be recognized more accurately.

Description

technical field [0001] The invention relates to the field of computer intelligent monitoring video processing, in particular to a method for automatically identifying abnormal speed events in monitoring video. Background technique [0002] In recent years, with the continuous progress and development of society, more and more public places and even private places have begun to install monitoring equipment. As people's awareness of safety precautions continues to increase, the market's demand for recording and alarm systems is also increasing, which makes video surveillance widely used in all aspects of production and life. However, the general video surveillance system requires a lot of manual work, so there are often omissions due to the fatigue of the monitoring personnel. In fact, most video surveillance systems do not have personnel present to monitor. This kind of video surveillance system only records video images. It can only be used for evidence collection after the...
