摘要:
针对利用SIFT算法的图像拼接在匹配过程中会出现一些错误的特征点问题，提出一种对SIFT算法优化的方法。利用算法将错误的特征点除去，并且利用最小二乘法对提纯后的图像进行拟合，提高了匹配精度，对拼接效果有较好的增强，同时也缩短了拼接的时间。实验结果表明，优化后的算法可实现相对较好效果的图像拼接。
In order to solve the problems of wrong feature points in the process of image mosaic algorithm based on SIFT, an optimized method is put forward. Using a new algorithm to eliminate the wrong feature points, and using the least square method to fit the new picture not only improve the matching accuracy, but also improve the image mosaic result and reduce the time of the image mosaic. Experimental results demonstrate that the method can produce high quality image mosaic.
