Abstract

The invention discloses a video based movement target detecting method. The method comprises the following steps: obtaining an initial background through an averaging method; initiating a vibe algorithm through the initial background, and building a background model; comparing each pixel in current frame through the background model to obtain background and foreground; if the times that any pixelpoint is continuously treated as the foreground are beyond the threshold, replacing in the background model as a new background sample, and updating the background model in the previous step; and if the times that any pixel point is treated as the foreground are less than the threshold, treating as the movement target and outputting, thus realizing the detection of the movement target. According to the method, the initial background is obtained by the multi-frame averaging method and replaces the first frame of the video to build the background model, and the background sample is updated in real time in the following detecting process, so that ghost and shadow can be effectively removed; and the detection in later period can be accurately carried out.

Description

technical field [0001] The invention relates to the field of target detection, in particular to a video-based moving target detection method. Background technique [0002] With the continuous and rapid development of urbanization in my country, the number of cars and the number of roads open to traffic continue to increase. The development of Intelligent Transportation System (Intelligent Transportation System, ITS) has a good effect on alleviating traffic congestion and other problems, and moving object detection is Important research content of intelligent transportation system. The ViBe algorithm performs well in many moving target detection methods. However, the ViBe algorithm only uses the first frame of the video for the establishment of the background model, resulting in "ghosting" in the detection effect. The creator of the algorithm simply regards the "ghost" as the foreground without any special treatment. Since ViBe's suppression of ghosts is a slow process, dur...
