Research on obstacle recognition and distance calculation based on the structure of the road
2015
Based on Machine Vision, the paper research a method to detect obstacles and calculate the distance between the obstacle and moving vehicles. First it uses the shadow detection method to determine approximate location of the obstacle and adopt corner detection method to detect the obstacle contour information. Then, the minimum bounding rectangle method is used to accurately framed obstacles vehicles. Finally, based on the principle of the distance in the camera, the obstacle distance measurement formula is built. Experimental results show that the algorithm can accurately locate obstacles and measure the actual distance between the moving vehicle and the obstacles.
