THE RESEARCH OF ROUTE NAVIGATION BASED ON VISUAL NAVIGATION
In order to solve the problems of Image pretreatment and the extraction of navigation line on agricultural machinery visual navigation, a route navigating system based on improved HOUGH transform is brought forward. First, extract the set of points from the original image based on the threshold segmentation and edge detection. Second, an improved HOUGH transform algorithm is used on detecting the route. This system is based on DM642 DSP and ARM9 Integrated Development Environment, which have achieved satisfactory experimental results.
