一种有效的角点检测与匹配算法

角点的检测和匹配是三维重建工作的基础部分，也是关系到三维图像重建准确性的重要部分。提出了一种角点检测算法，集多种经典算法之长处，用双重不同的判定条件，提高了的角点检测的速度，增加了检测出的角点数，并且改善了角点的精确度。在此基础上进一步提出使用简单的模板匹配方法进行角点匹配。实验表明，该算法简单且精确度高．优于其他现有的算法，而且能够得到足够多的匹配对进行下一步的三维重建工作。

An Efficient Algorithm of Corner Detecting and Matching

In three-dimensional reconstruction,the task of corner-detecting and matching,not only is a basic part,but also has respect to veracity of the reconstruction.The algorithm introduced in this paper,with the merits of some classical algorithms,using two different conditions to make judgment,which can effectively improve the velocity of detecting,the quantity of corners,and the precision of corner-detecting.On this basis,a simple method,using the template matching,is used to match the corners.Experiments show ...
