摘要
提出了一种基于特征的图像自动拼接算法,本算法采用Harris角点检测算子提取特征点,并对特征角点进行初始匹配与求精,利用最小中值法去除局外点,使变换矩阵计算精确。最后进行颜色融合,生成无缝拼接图像,在大多数情况下,算法可自动完成,实验结果表明,该算法取得了理想的拼接效果。
In this paper, an automatic image mosaic algorithm based on feature is presented. In this algorithm, Harris corner detector is used to extract feature points. Then the feature points is matchedtwice, use least median algorithm to delete outliers, so more accurate transform matrix is computed. Finally the image color of the overlapping band is smoothed with fusion algorithm to obtain seamless mosaic image. The algorithm performs automatically. The result shows that the algorithm can gain ideal mosaic image.
