Abstract

The invention provides a method for detecting a movement target based on colored RGB three-pane color-change frame difference. The method comprises the steps of acquiring colored images of two adjacent frames in the scene to be measured; extracting red, green and blue planes from the color images and storing; performing differential operation for the red, green and blue planes by the frame difference method according to the extracted six planes so as to generate three differential images; sequentially calculating for pixel points of the three differential images; performing binarization for each pixel on the obtained new differential image so as to obtain the contour of the movement target. According to the method, the frame differential calculation is respectively performed for three RGB planes; whether the color difference changes of the pixel points at the same coordinate point are the same; the color difference changes are overlapped and calculated; therefore, a large difference occurs between the movement target contour pixel value and the pixel value of other areas, and as a result, the movement target can be accurately extracted, and the complete information of the movement target contour can be maintained to the maximum.

Description

technical field [0001] The invention relates to a method for detecting a moving object, in particular to a method for detecting a moving object based on the color change frame difference of three color RGB planes. Background technique [0002] Video technology has broad prospects for development in the fields of scientific research and engineering applications. In the process of video image processing, the detection and extraction of moving objects is a key technology. The purpose of moving target detection and extraction is to separate the moving target from the background image, which is the segmentation problem of the moving target and the background. [0003] The primary task of video image processing is to detect moving targets from video image sequences. How to quickly and effectively separate the background and targets is the focus and focus of current research. At present, the commonly used detection algorithms include optical flow method, background difference met...
