摘　　要：提出一种基于多幅图像的低成本的重建目标三维人体模型的方法。首先建立每幅图像上特征点与原始模型特征点之间的对应关系,然后使用基于径向基函数方法对原始模型进行变形从而获得目标模型并对目标模型应用三种过滤器进行局部修复,最后使用视角无关的方法实现纹理映射和基于顶点混合的方法实现皮肤骨骼运动系统。实验结果表明该方法精度高,实用快捷且成本低廉。A method for low-cost 3D specific human model reconstruction from multi-image was proposed. First, the feature points on each image were matched with their generic model. Then a deformation from radial basic function was performed to obtain specific model. After that, three kinds of filters were used to refine the specific model. Finally the surface of model was texture mapped by viewpoint-independent algorithm, and skin-skeleton system by vertex blending algorithm as well. The experimental results show that this method is accurate, easy to implement and of low-cost.
