Abstract: In this paper, a video image processing detection algorithm at traffic intersection was designed using Halcon computer vision algorithm library in order to provide a solution for traffic flow detection in intelligent transportation. Application of the moving target detection method based on hybrid Gaussian background model was studied, and the basic algorithm principle was analyzed to select key functions in Halcon for the detection algorithm in HDevelop development environment. In the verification stage, continuous 500 frames of images were processed and analyzed. The result showed that this algorithm could capture moving vehicle targets in the traffic road quite effectively at an average processing speed of 5.8ms per frame, which could meet the real-time requirements.
