Obstacle Avoidance Algorithm. 1 Recognize and classify an obstacle marker as a triangle square or circle 2 find the position and area of the marker in the image x p y p and A p 3 compare A p to the actual area of the marker A r and use the camera focal length f and the marker position in the image to calculate the 3D obstacle. A new obstacle avoidance method for autonomous vehicles called obstacle-dependent Gaussian potential field ODG-PF was designed and implemented. According to it when an obstacle is encountered the robot fully circles the object in order to find the point with the shortest distance to the goal then leaves the boundary of the obstacle from this point see figure 12. The obstacle detection algorithm is based on four main steps which are illustrated in Figure 6.
