基于图像处理的激光双三角法测量三维曲面

摘要

In this paper nonlinear measuring errors due to laser triangle measurement for 3-D surface and various factors affecting measuring accuracy were generally introduced.Using one optical system with double camera,developing the new way of multi-dimensional fitting and scaling, reducing the nonlinear error and measuring dead area.At the same time,the measuring accuracy was greatly improved.%分析了激光三角法在3D曲面测量系统中的非线性误差，及影响测量精度的各方面因素。提出了采用双摄像头的光学系统，利用基于神经网络的多维拟和标定的方法，较好地消除各种非线性系统误差和测量盲点问题，并且大大提高了测量精度。
