Epipole-based visual servoing for nonholonomic mobile robots

摘要

A new image-based visual servoing algorithm is presented for nonholonomic mobile robots. The algorithm, based on epipolar geometry, consists of three independent and sequential steps making use of both the estimated epipoles and the image features. In particular, due to the nonlinear dynamics of the camera-robot system, an input-output feedback linearizing control law is used during the second step. Simulations results are presented to validate the proposed visual servoing technique.
