一种单双目视觉系统结合的三维测量方法

A Three-Dimensional Measurement Method by Combining Binocular and Monocular Vision Systems

在投影栅相位法的单目和双目三维测量结构的基础上,提出了一种单双目结合的三维测量方法。采用双目测量系统的架构,对两相机的公共区域使用双目的方法进行复现,同时分别将两个相机与投影仪组成两个单目测量系统,通过标定的统一可以将两者的世界坐标系统一到一个共同的基准上,利用单目的测量结果对双目测量的缺失区域进行填补。在对石膏头像的测量中,利用该方法避免了双目测量中在鼻梁附近出现的数据丢失。在保证双目复现区域精度的基础上,该方法有效地改进了测量结果的完整性。

Based on the combination of binocular vision measurement and monocular vision measurement, a new three-dimensional （3D） measurement method is proposed with the two systems, the common field of view is reconstructed by a binocular vision system, and the unmatched area is filled up by two monocular vision systems, which is composed of the projector and cameras separately. Their world cooridinate systems can be unified to a common reference with uniform calibration. In the measurement of gesso head portrait, the data missing near the nose can be avoided by this method. While the reconstruction precision of the binocular vision system is maintained, this method improves the measurement results efficiently.
