　　In this paper, mathematical modeling and simulation technology was used to design a type of mirror surface fitting method.With the geometric rules which mirror surface displayed, and step by step calculating strategies, a new method based on triangle-based linear curved surface fitting algorithm was constructed.After mirror surface grid and analysis of each simple surface parameters, the fitting surface was connected by the mesh nodes, which were grid points fitted with triangle-based linear fitting algorithm.Moreover, the Matlab simulations based on the triangular surface fitting and least squares method were compared.The result of the experiments showed that the triangle-based linear curved surface was more smooth, high accuracy, superiority and validity.
