Title Sports information resolving of intelligent vehicle based on video
Abstract
With the rapid development of science and technology, computer vision and digital image processing technology has been widely used, and analyzing the video of moving objects is one of the more extensive application prospects in the direction, it also has important theoretical and practical value on machine navigation, industrial inspection, visual warning, visual surveillance and medical image analysis.
In this paper, for the need of the multi-target distributed control system, parameters estimation of moving target based on the video image is studied. Firstly, requirements analysis of multi-agent system is proposed, and the general framework of the video image is given. Then, image prepossessing of a frame image in video is discussed and realized， such as gray-scale conversion, image binarization, median filtering and contour extraction. Finally, the whole video is processed by inter-frame difference methods; the position and velocity of the vehicles are achieved.
