摘要:
We present a method for precise calibration of the pan-tilt unit based on the Levenberg-Marquardt optimization. Two different error functions are proposed-the first based on the position of the calibration marker and the second one indirectly incorporating the orientation of the marker. The proposed method was experimentally evaluated and the obtained results confirm its usefulness for the precise stereo-head operation.
