| 摘 要： | 针对尺度不变的特征变换方法(SIFT)运用在图像拼接上存在错误匹配,以及匹配后点对位置并不严格对应的两点不足,提出运用随机取样一致性算法(RANSAC)筛选匹配后的点对,并借鉴KLT追踪算法修正特征点的位置,进而得到精确的变换矩阵.实验结果表明,该算法在继承了SIFT算法较强鲁棒性的同时,进一步提升了拼接的精度.

| Abstract: | Aimed at the two inadequacies appeared when applying Scale Invariant Feature Transform(SIFT) to image mosaic,they are,wrongly matching and poor point-pair corresponding,this paper proposed to make use of RANSAC algorithm to filter the matched point-pairs and refering to Kanade-Lucas-Tomasi(KLT) tracing algorithm to modify the position of feature points,so as to get accurate transformation matrix.Experiments show that this algorithm is as robust as SIFT,meanwhile,the precision is improved. |
