To improve the precision of the detection of linear targets in high-resolution remote sensing image,the geometric features of linear target are analyzed,and an improved Hough transform algorithm for linear target detection is proposed.The algorithm combines the Freeman chain code and Hough transform,and the method of Hough transform for the edge of the linear object is also employed.A problem of duplicate detection,low efficiency,poor accuracy is solved effectively.The algorithm is tested on No.3resources satellite images,the experimental results prove that the proposed algorithm can detect parallel linear targets effectively in the images,and can process well in real-time.
