Pose and position calibration of laser displacement sensor in aspheric measurement

This paper suggest a model to calibration the pose and position of laser displacement sensor. In practice, the direction of laser and motion axis can´t completely overlap. It will cause some errors in measurement. And it will have a great influence on the measurement result, especially in the large-scale measurement. Through the calibration method of this paper, the error cause by pose and position will be reduced in some extend. The calibration method and the evaluation result are described in detail in the paper.
