Paper Abstract
In line-structured light measurement systems, in order to achieve higher 3D reconstruction accuracy, it is necessary to calibrate the rotating shaft accurately. When the sensor and the tested part are in the same horizontal plane, it is impossible to measure the characteristic point data of the whole week, so that the calibration of the rotating shaft is inaccuracy. Therefore, in this paper a calibration method of rotating axis based on coordinate transformation is proposed, the sensor performs rotational axis coordinate calibration above the planar target and transform the coordinate of the rotating axis in the sensor coordinate system above the target into the horizontal coordinate system by means of coordinate transformation. This rotary axis calibration method has a certain feasibility because it adopts the method of full-circle revolving calibration, which can effectively improve the calibration accuracy.
