Rearch on Edge Feature Extracting for Visual Navigation Marking Line of AGV

It researched the edge feature extraction of the navigation identification line,and specified the study of the line feature extraction algorithm,and used VC++ to take an experiment by the algorithm,showing that the method can extract edge feature effectively.For extracting edge feature of visual navigation marking line of AGV based on visual navigation,it presented a novel edge extracting method.Firstly,it used iterative threshold selection method to segment the image,and generate the binary image,then it used an improved median filter on the image smoothing.Finally it used edge tracing method to extract edge of the smoothed binary image.And it used the proposed algorithm to process the marking line image in VC++,successfully extracting a clear image of the edge.
