研究主题:牲畜体表信息的三维重建

本文参考Leonid Pishchulinp论文[Building Statistical Shape Spaces for 3D Human Modeling]的方法,使用基于模板的非刚配准来实现三维重建。该方法包括初始化和非刚配准两个步骤。本项目在原有算法的基础上,通过修改其中算法参数和模型,将原有算法从人体转移到牲畜上,并达到一定的精度。

5.1 数据准备

模板数据:普通猪的网格数据

扫描数据:第四章获取的归一化后猪的点云数据

另外还需要选取一些特征点,使配准效果更好。因此,我们根据农业上猪的体尺测量,在模板数据和扫描数据上分别选取了37个对应的特征点。
