摘要
提出了一种基于相关系数法的彩色图像分3个波段匹配方法。本方法分两步进行影像匹配,首先利用相关系数作为匹配测度对同一个彩色影像的不同波段实施粗匹配,通过结果剔除误匹配点,然后在初匹配的结果基础上采用最小二乘实现亚像素级匹配。实验结果表明彩色影像立体匹配方法是精确有效的。
In this paper, we introduced a color image three-band matching method based on correlation coefficient. We divided this method into two steps for image matching. Firstly, we used the correlation coefficient as matching measure to conduct rough matching for different bands of the same color image, and eliminated the wrong matching points through the results. And then, we used the least square method to realize sub-pixel matching based on the initial matching results. The experimental result shows that the color image stereo matching method is accuracy and efficient.
