摘要
对激光扫描三角法在用于三维非接触测量中的精度影响因素进行了较全面的分析与研究，并提出了该方法在提高测量精度方面应采取的措施，特别是基于神经网络的多维拟合标定方法可大大提高测量的精度，给出了实验研究的结果。
In the paper, the precision factors in the laser scanning triangulation method for the non_contact 3D measurement have been analysed. And some new ways to raise the precision have been proposed. Especially, the multi_dimension fitting method based on ANN is a most useful one for raising the precision at here. Finally, some reseach results are shown.
