Abstract :
This paper illustrates the structure of the uncalibrated discrete dynamic look-and-move visual servo system and proposes a new visual servo scheme without calibration for static image target, which estimates the pseudo-inverse matrix of image Jacobian on-line with the help of recursive least square algorithm. The convergence condition of this scheme for proportional controller is proved by Lyapunov stability theory in this paper. In the end, the simulation results are presented to demonstrate the performances of the proposed scheme.
