A Line Tracking Algorithm Based on Image Processing

Line follower robots can be used for many important robotic and industrial tasks. One of the most important factors in these methods is the computational requirement of the algorithm. The paper presents a novel method for the line following problem using image processing technique. Our main goal is to find an efficient way with real-time computing to track a line using a camera-equipped robot. To measure the effectiveness of the presented method, we compare two line following robots with the line tracking method being the only difference between them. The first robot uses the proposed camera-based method and the other robot has reflective optical sensors in order to determine the position of the line. These real life experiments demonstrate the efficiency of the presented method.
