可变形物体的配准技术

Registration Techniques for Deformable Objects

University of Bonn(波恩大学)

摘要:

通常,非刚性配准的问题是关于匹配在两个不同时间点拍摄的动态对象的两个不同扫描。这些扫描可以经历刚性运动和非刚性变形。由于模型的新部分可能进入视图,而其他部分在两次扫描之间被遮挡,因此重叠区域是两次扫描的子集。在最一般的设置中,没有给出先验模板形状,并且没有标记或显式特征点对应可用。因此,这种情况是一个部分匹配问题,它考虑了后续扫描经历小变形同时具有大量重叠区域的假设[28]。本论文所要解决的问题是映射变形的物体和定位相机在环境中的同一时间。

英文摘要:

In general, the problem of non-rigid registration is about matching two different scans of a dynamic object taken at two different points in time. These scans can undergo both rigid motions and non-rigid deformations. Since new parts of the model may come into view and other parts get occluded in between two scans, the region of overlap is a subset of both scans. In the most general setting, no prior template shape is given and no markers or explicit feature point correspondences are available. So, this case is a partial matching problem that takes into account the assumption that consequent scans undergo small deformations while having a significant amount of overlapping area [28]. The problem which this thesis is addressing is mapping deforming objects and localizing cameras in the environment at the same time.
