摘要
工业CT图像的目标匹配定位采用Hausdorff距离作为相似性度量,定义两个点集上的最大/小距离。以HausdorffCANNY边缘检测算子在求得边缘位置信息同时获得边缘像素点方向信息。并通过CANNY算子提取边缘信息作为匹配特征,利用Hausdorff距离模板匹配,在距离变换空间内实现目标匹配定位。
The measurement of Hausdorff distance is adopted in location method of object matching for industry CT image, the max-min distance of two sets is defined. The information of edge position and direction information of pixels was detected using CANNY operator. And then the edge information captured by CANNY operator was used as matching feature, model was matched with Hausdorff distance, and object matching and location was realized in the distance space.
