摘　　要：针对三维重建技术的需要,提出一种基于SUSAN角点匹配的技术,实现了对多视角二维图像的精确匹配定位.该技术首先利用了相关匹配技术,对多幅图像中的相似区域进行粗略定位,再在该粗略区域内,分别提取SUSAN角点的位置,各视角图像中的角点均对应于空间的同一点.实验证明,该技术可以有效地计算出空间特征点的位置.A method based on SUSAN corner detector is proposed for the need of three-dimensional reconstruction,which realizes the accurately matching position-setting for the multi-angle-of-view image.Relevant matching technology is used to get the rough position of the matched area in a few images,and SUSAN detector is used to get the corner positions which are related with the same point in space.It is proved that the position of the point in space can be calculated efficiently.
