摘要
介绍了基于双目单视面和结构光的三维复原方法。分析了影响复原精度的3个因素,并通过仿真和实验测定了光条在空间中不同位置所还原的三维信息的误差;分析了双目相机的相对角度以及相对距离对精度的影响。得出了一个适用于工程应用的结论,并给出了双目相机的最佳相对位置以及待测物的最优距离范围。在给定的实验条件下,三维复原测量精度达到了0.1 mm。
A method of 3 D reconstruction based on horopter and structural light is introduced. In order to estimate precision of 3D restoration, three factors that affect precision of 3D restoration are analyzed. The error of the restored 3D information of the light bar in different spatial position is measured through simulation and experiment. The influence of relative angle of binocular camera and relative distance on precision is analyzed. A conclusion suitable for engineering application is drawn, the optimal relative position of binocular camera and the optimal distance range of the object to be test are given. Under the given experimental condition, measurement precision of 3D restoration reach 0. 1 mm.
