Image‐based visual target following for a nonholonomic wheeled mobile robot with a single fixed camera

Abstract

This paper addresses the problem of visual target following for a nonholonomic wheeled mobile robot with a single fixed camera. For the problem, we propose a control scheme composed of vision-based trajectory planning and tracking control. We present online trajectory planning based on image-based visual servoing. The key idea is to compensate the target object motion.In particular, we focus on visual feature motion resulting from the target object motion. Tracking control to the generated trajectory can therefore achieve visual target following precisely even if the target object is moving. Our proposed scheme can be applied to, e.g. robotic systems for autonomous guard and observation. The effectiveness of the control system is evaluated experimentally.
