With computer technology to the rapid development of image processing with our work and lifestyle are closely related, which has been widely used in many fields of science and engineering.
The author mainly explained what the image processing was, the basic demanded of the image processing. Secondly, expounded the characteristic, function and the construction cycle of the development instrument of digital image processing. Thirdly the author made three concrete experiments，which were used the VC++ as its development instrument, the Opencv as its moving platform. Meanwhile author introduced the technique which the sport examining system used. In this article author introduced the detailed sequence of the system as well.
The motion detection system is to achieve a series of pictures of tracking moving objects designed and It adopted a series of pictures, photographs extracted from the background to identify moving objects. Turn right track moving objects, object movement to be traced. Specific application of the technology to read image data, image median filtering, gray image, gradient image acquisition, Image features regional identification, the two image matching. Based on a series of pictures, photographs extracted background to identify moving objects. turn right track moving objects, to be track the movement of objects.
