abstract
Hough transform is an important part of digital image processing. In 1962, Hough transform as a patent has been published for more than 50 years in the United States.It attracted many domestic and foreign scholars and technicians universal concern because of its obvious advantages and value of nature. Hough transform is an effective algorithm for detecting the long line .The design is to study the use of rectangular Hough transform detection Hough transform,and we make use of the VisualC++ Programming for detecting Parallel Lines.In this paper,we analyze and summerize the image of the line detection algorithm,and we introduce the development of software .The results showed that we use the basic algorithm can still retain the traditional Hough transform, and is not sensitive to the interference in the picture, and still can carry on the right detection when the image is incomplete.
