摘　　要：提出了一种基于Ham ilton方程粘性解理论的由阴影恢复物体表面的改进算法。应用针孔相机模型建模,建立新的Ham il-ton偏微分方程,从而得到物体三维形状。对合成图像和实际图像的实验表明算法可以得到较好的从阴影恢复形状的重构效果图。An improved algorithm of three dimensional shape from shading based upon the notion of viscosity solutions of Hamilton equations was proposed. First, the camera as a pinhole model is built. Then a new Hamilton partial differential equation is obtained and the surface of the object could be reconstructed. Experiments thetic and real images show that this method can obtain more accurate reconstructed results for shape from problem.
