| 摘 要： | 在不同传感器图像的匹配中角点是重要匹配特征,为满足实际一些具有方向性的成像传感器图像匹配的需要,进行稳定可靠、具有方向性角点特征的检测是必需的.本文采用方向性的SUSAN角点检测算法,将SUSAN算子计算区域限定在具有一定指向的扇区,使之具有方向性检测角点特征.实验证明,该算法简单、实用和有效.

| Abstract: | The corner feature is an important character for image matching of the different sensors,the corner is defined as the position of very high curvature on image edge commonly.In order to meet practice need of image matching for imaging sensor with orientation,it is necessary to detect corner feature that is stabilization,credibility and orientation.In this paper the algorithm of orientation SUSAN corner detection is adopted,the method is the calculating region of SUSAN operation limited an appointed sector,so... |
