Gq. Wei et G. Hirzinger, ACTIVE SELF-CALIBRATION OF HAND-MOUNTED LASER RANGE FINDERS, IEEE transactions on robotics and automation, 14(3), 1998, pp. 493-497
In this paper, we propose a method for self-calibration of robotic han
d-mounted laser range finders by means of active motion of the robot.
Through range-measuring a plane of unknown position and orientation, t
he mounting parameters of the range finders and the coordinates of the
world plane are estimated. Systematic measurement errors can also be
calibrated at the same time. The approach is fully autonomous, in that
no initial guesses of the unknown parameters are to be provided from
the outside by humans for the solution of a set of nonlinear equations
, In fact, the initial values are all found in closed forms by the alg
orithm itself. Sufficient conditions for a unique solution are derived
in terms of controlled motion sequences. Experimental results in both
a simulated and a real environments are reported.
