摘　　要：在多幅图像融合的基础上,研究物体三维形貌恢复方法。首先利用小波变换对几幅不同的源图像作融合,提高了源图像的质量,克服了传统的基于阴影恢复形状方法(SFS)因源图像质量低使恢复结果失真的局限性。在此基础上假设反射模型是包含漫反射和镜面反射的复合反射模型,再利用SFS方法恢复物体的三维形貌。实验表明,该方法对恢复结果有了很大的改善。This paper deals with the research on 3D reconstruction method based on image fusion for several images： the quality of original image was improved by image fusion with several different original images that was carried out by wavelet transform, which could overcome the limitation because of the poor quality of original image. Thenwe proposed a hybrid reflection model which contains both diffuse reflectance and specular reflectance. At last, we used SFS （shape from shading） method to reconstruct the shape of object. The experimental results demonstrate that this method could improve the result greatly.
