针对图像配准中常出现的RST(旋转-比例-平移)变换，推导出了相应的盒距离变换公式。与传统的基于广
义仿射变换的Hausdorff盒距离变换公式相比，缩小了搜索距离空间。在计算Voronoi表面时，根据Hausdorff距
离的计算需要提出比较滑动窗口的区域Voronoi表面，节省了计算Voronoi表面的时间。并且在利用边缘点计算
Hausdorff距离时，剔除琐碎的边缘，仅使用较长的边缘计算。试验结果表明，这些改进方法较大地提高了基于
Hausdorff距离的图像配准的计算速度。
,For image registration often appears RST (rotation- the ratio of- translation) transform, derived from the corresponding transformation formula box. With the traditional affine transform based on generalized distance transform of the Hausdorff formula box compared to the distance to narrow the search space. Voronoi surface in the calculation, according to the calculation of Hausdorff distance sliding window need to compare the regional Voronoi surface Voronoi surface is calculated to save time. Edge points and the calculation in the use of Hausdorff distance, remove the edge of trivial, only the edge of a longer calculation. Test results show that the method greatly improved Hausdorff distance-based image registration of the computing speed.
