主轴法在三维图像匹配中的应用

Principal axes method for three-dimensional image registration

提出了一种三维图像点集的匹配对准算法———主轴旋转法 (PAX) .通过计算三维图像的质心和主轴来确定图像的朝向 ,利用一系列刚性变换最终对准图像 .算法具有简单、快速、适用面广等优点 .

In this paper, an algorithm for registering three dimensional image points set-pricipal axes method is presented. By calculating the centroids and principal axes, the algorithm can determine the orientation of the images, and align them by using a series of rigid translations. The algorithm is simple but rapid, and can be used on various occasions.
