【Abstract】 A real-time algorithm of post detection is proposed using dynamic image processing technology. First, a fast median filter is adopted to denoise. A laconic algorithm for edge extraction is presented. The edge with the width of single pixel can be extracted quickly using this method. Then two frames are matched with the method of adaptive multi-line matching. With the information of dif- ference image, the post is segmented from the image. The parameter of post is figured out in the end. The experiment on computer shows this algorithm can detect post efficiently and quickly.更多还原
