Abstract
Hough transform is used to extract line, but Hough transform can not distinguish the line and line segment, otherwise time complexity and space complexity are very large, this paper makes Hough transform to search line segment by adding a two-dimensional counter, and uses Canny algorithm to detect edge pixel which decreases computational complexity and increases extraction accuracy. According to the characteristics of city road network of satellite, first processes the image, then checks the city road-net by using improved Hough transform, the experiment proves the efficiency.关键词
