Adaptive visual servo control to simultaneously stabilize image and pose error

A novel, Lyapunov-based visual servo controller is presented that stabilizes both the entire image and pose error vectors simultaneously, rather than a subset of the errors. Furthermore, the controller uses adaptive depth estimation to eliminate the need to measure depth or obtain knowledge of the scene. A stability proof is presented. Simulation and experimental results compare the performance of the proposed method to PBVS, IBVS and 2.5D VS approaches. (C) 2011 Published by Elsevier Ltd.
