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.
