摘　　要：为了观测关节炎患者的病情发展,本文利用计算各对应点之间的软骨厚度差来监测厚度变化。但必须知道2个软骨点云各对应关系,本文提出使用主轴变换方法解决点云空间对齐问题,然后使用Munkres分配算法求得点对应关系,从而达到跟踪目的。In order to observe the progression of arthritis patients, the paper uses the calculated thickness difference between thecorresponding points to monitor the thickness change. However, the correspondence relationship between two cartilage point cloudsmust be known. The paper proposes using the spindle transformation method to solve the aligning problem of point cloud space, andthe Munkres allocation algorithm is adopted to find out the point correspondence relationship for achieving the purpose of tracking.
