摘　　要：该文提出的方法，使用了基于投影的粗筛选和候选点的策略，使用基于距离约束对匹配点对进行校正和消除错误匹配，提高了计算速度和可靠性。实验结果证明，提出的方法具有较大的实用性。This paper proposed a new stable method for console point matching, which can be used in image registration under shift and rotation. The new method firstly extracts console points in the first image of an image sequence and then searches matching points in the consecutive images. Different to conventional methods, it adopts projection of pixel to filter console points and choose many possible matching point for one reference console point, and adopts constrain of distance to revise matching and removing false matching. These make it fast and reliable. Experiments prove this method is practical and reliable.
