| 摘 要： | 针对耳廓多角度扫描获取的三维网格合并问题，提出了一种新的三维网格合并方法—去补丁合并法.首先基于kd-tree算法将三维耳廓配准后的两幅网格快速分割为重叠区域与非重叠区域；然后根据连通性对重叠区域和非重叠区域进行分块，并从重叠区域分块中去除冗余的补丁块、构建边界点；最后基于边界点将保留的重叠区域网格与邻接的非重叠区域网格缝合.实验结果表明，与同类算法相比，本文方法具有较好的合并效果与较高的计算效率.

| Abstract: | To merge the multiple meshes of the same human ear, which was scanned from different perspectives, this paper proposes a novel approach for 3D ear mesh merge-Patch Removing. First, we use kd-tree to segment the two registration meshes of 3D ear into un-overlapping area and overlapped area; Then, segment the un-overlapping area and overlapping into blocks according to their connectivity, discard the redundant patch in the overlapping area, and find the points on the boundary of blocks; Finally, to merge the 3D ear meshes, we stitch the mesh blocks in the un-overlapping area and the rest of the overlapping area along the boundary points. Our experiments show that, comparing with other works, our algorithm can merge the 3D ear meshes with more effectively and higher computational efficiency. |
