The invention relates to the technical field of digital measurement. The invention discloses an optical target point projection planning method based on Gaussian curvature. According to the method, the density of target points projected by an optical point projector is adaptively adjusted according to the Gaussian curvature of a local area on the surface of an aircraft; when the aircraft surface contour and the assembly quality are detected, different requirements of different areas for the density of target points can be met, optical target point projection distortion caused by the large bending degree of the measurement surface is reduced, target point recognition and calculation of photogrammetry and other systems are facilitated, and the measurement precision and the measurement efficiency are improved.
本申请涉及数字化测量技术领域，公开了一种基于高斯曲率的光学靶标点投影规划方法，本方法根据飞机表面局部区域的高斯曲率大小，自适应地调整光学投点器投射的靶标点密度，在对飞机表面轮廓以及装配质量进行检测时，能够满足不同区域对靶标点密度的不同要求，减小了因测量表面弯曲程度较大而造成的光学靶标点投影失真，便于摄影测量等系统对靶标点的识别和计算，提高了测量精度和测量效率。
