A large amount of geometric data of a remote target can be obtained in a short time by collecting photographs based on photogrammetry. photogrammetry has become an important method to extract the geometric parameters of rock mass discontinuities. The purpose of this paper is to quantitatively analyze the accuracy of the geometric parameters of the three-dimensional model obtained by photogrammetry through a physical model test, and thus to obtain the inspiration of the photogrammetric accuracy of the rock mass discontinuities. The results of the physical model test shows that the measured error of the geometric parameters is very small, and the measured values can satisfy engineering requirement.
