Method for shape from shading based on mesh
一种基于网格的从明暗恢复形状方法

Concerning the current problems of high computation cost and poor convergence performance during Shape From Shading (SFS), a mesh-based resolution was proposed. The original image was divided into several regions by the means of image preprocessing and region segmentation and were transformed them into triangular mesh. And then equations with regard to each vertex of the mesh in three-dimensional space were established. Finally the result resolved form equations was straightly applied to the graphic pipeline of real-time three-dimensional render engine such as OpenGL or DirectX to accomplish the model reconstruction and rendering. The results of simulation show that the method is of convenient calculation and can reconstruct the original model realistically.
