针对待配准图在参考图上存在多个相似的区域,传统的SIFT(Scale Invariable Feature Transformation)算法导致匹配点数量较少,影响对模型变换参数估计的情况,提出了结合区域分割的SIFT特征提取和特征匹配的方法。算法首先对图片进行边缘检测以及形态学滤波预处理,提取出边缘丰富区,接着采用改进的简化SIFT,并在匹配阶段,结合强匹配点对与SSDA(Sequential Similarity Detection Algorithm)检测出的粗匹配位置进行匹配,增加了算法区分相似区域的能力。与原始算法相比,该算法可以得到更多正确的匹配点对,时效性上更优。
Aiming at solving the situation that the original SIFT algorithm can only get few number of matching points if there are a few regions similar to the matching image on the reference image
which will affect the estimation of parameters in the transformation model. Proposed algorithm first apply edge detection and morphology filtering in the image preprocessing stage to extract edge-abundant areas
then adopt an improved simplified SIFT
and combine the rough matching area detected by SSDA and robust matching points while matching points
thus improving the discrepancy of similar points in the algorithm. Compared to the original algorithm
our proposed algorithm can get more correct matching points and is less time consuming.
