基于特征匹配的三维试衣效果

 基于特征匹配的方法实现了三维试衣效果的展示。该方法基于双二次Bezier曲面局部拟合服装模型和人体模型的网格顶点及其邻近点，估算出人体和服装模型网格顶点的高斯曲率和平均曲率，然后提取出人体和服装模型两点集的特征匹配点。为了减少误匹配和避免多重对应关系，使用曲率约束关系或通过少量交互操作得到了正确的关键特征匹配点对，并运用最小距离目标函数得到两模型匹配的三维坐标变换矩阵，实现服装与人体模型的粗匹配，再对服装模型进行缩放和二次匹配，实现服装模型和人体模型的精确匹配。实验结果表明该算法方便、有效。

3D clothing fitting research based on feature matching

This paper presents a 3D clothing fitting via the feature matching.Firstly,the method fits each vertex and its local neighborhood of the clothing and human models by constructing the biquadratic Bezier surface.It can estimate the Gaussian curvature and the mean curvature of each vertex.Then,the feature points of two mesh models are extracted according to curvatures.In order to reduce the wrong matching and avoid the multiple matching relations,it uses the curvature constraint conditions or few interactive o...
