摘要 针对SIFT算法经常出现误匹配的情况,提出一种匹配算法。该方法在SIFT算法之后嵌入一种旋转模板匹配算法。利用特征点方向,对图像进行旋转,使用旋转后的特征点邻域进行模板匹配,对SIFT算法的结果进行二次筛选。实验证明,该方法能够有效地提高SIFT算法匹配正确率,实现对SIFT算法的改良。 In order to reduce mismatches in SIFT, presents a method that the image is rotated by the point' s direction and uses templates matching after SIFT's processing. Advance the second filtering to SIFT algorithm. The experiments show that this method will improve the SIFT's performence as raising the ratio of correct.
