Techniques Based on Image Segmentation Road
Abstract: The main content of this paper is image based road edge segmentation technology. First will shoot themselves road images are image processing, then the more practical and classical edge detection algorithm of image edge extraction. In order to improve the practicability and anti-interference ability of the road edge segmentation, a road edge segmentation algorithm is proposed in this paper. This algorithm uses the road marking as the basis of segmentation. Based on road image segmentation technology implementation of road and terrain surface recognition has very important role, on the future of tourism information distribution, geological resources detection and protection of land resources, such as, with very urgent realistic needs and applications. Firstly on existing edges of the image segmentation method was studied, Sobel operator, pull Blas operator, Roberts operator, and Prewitt edge detection template operator is analyzed respectively, and then put forward a more practical algorithm to achieve the road image segmentation.
