摘要: 传统方法在三维动漫人物造型重构过程中未确定关键特征点,导致姿态图像匹配度低和收敛速度慢,为此设计一种基于拓扑分析的三维动漫人物造型重构方法。引用拓扑分析确定三维动漫人物造型的点、线、面结构,运用基于融合技术的边缘检测方法提取造型特征点,计算特征点的梯度值和梯度方向,以此来确定关键特征点,生成主方向和特征描述符。在此基础上计算与其对应的源数据库中关键点的描述符距离,根据最小距离和次小距离的比值实现特征点的匹配,利用交互式几何约束变形完成三维动漫人物造型重构。测试结果表明:设计的三维动漫人物造型重构方法的姿态图像匹配度整体在0.6以上,远高于传统重构方法的匹配度,且该方法的收敛速度较快,说明其适合应用在三维动漫人物造型重构设计中。

Abstract: Traditional methods do not determine the key feature points in the process of 3D animation character modeling reconstruction, which results in low matching degree and slow convergence speed of attitude image. Therefore, a 3D animation character modeling reconstruction method based on topology analysis is designed. Topological analysis is used to determine the point, line and face structure of 3D animation character modeling. The edge detection method based on fusion technology is used to extract feature points, and calculate the gradient value and gradient direction of feature points, so as to determine the key feature points and generate the main direction and feature descriptor. On this basis, the descriptor distance of the key points in the corresponding source database is calculated, and the feature points are matched according to the ratio of the minimum distance to the next small distance, and the 3D animation character modeling is reconstructed by interactive geometric constraint deformation. The test results show that the overall matching degree of the designed 3D animation character modeling reconstruction method is above 0.6, which is far higher than the matching degree of traditional reconstruction methods, and the convergence speed of the method is faster, which shows that it is suitable for the 3D animation character modeling reconstruction design.
