Abstract

This paper presents a switched homography-based visual control for differential drive vehicles. The goal is defined by an image taken at the desired position, which is the only previous information needed from the scene. The control takes into account the field-of-view constraints of the vision system through the specific design of the paths with optimality criteria. The optimal paths consist of straight lines and curves that saturate the sensor viewing angle. We present the controls that move the robot along these paths based on the convergence of the elements of the homography matrix. Our contribution is the design of the switched homography-based control, following optimal paths guaranteeing the visibility of the target.
