| Abstract: | In order to compensate the measuring errors due to the incident angle, this paper develops an error compensation method based on neural network. At first, BP neural network is employed to describe the mapping relationship between the measuring error and the precessing angle and nutation angle of normal. Then the mapping relationship is used to compensate measuring error in case that normal orientation is known. The experiment shows that accuracy of laser displacement sensor(LDS) can be improved remarkably by the developed error compensation method. On the basis of above research, the measuring error compensation method for free-form surface is proposed. |
