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 monocular and binocular 3D measurement structures of the projection grid phase method, a three-dimensional single-binocular measurement method is proposed. Using the architecture of binocular measuring system, the common area of the two cameras is reproduced by the binocular method. At the same time, the two cameras and the projector are respectively composed of two monocular measuring systems. Through the unity of calibration, the two worlds can be combined Coordinate systems, one to one common baseline, utilize monocular measurements to fill in missing regions of binocular measurements. In the measurement of gypsum avatars, this method is used to avoid data loss in the binocular near the bridge of the nose. On the basis of ensuring the accuracy of binocular reappearance area, this method effectively improves the integrity of measurement results.
