颜色纠正算法在手机全景图的应用研究

Research on Application of Color Correction for Mobile Panorama Imaging

针对原始图像序列曝光差异较大致使拼接痕迹明显这一问题,提出了一种新的手机全景图的颜色纠正算法,该算法通过在Ycbcr颜色空间里构造出一个全局调整函数计算出每一幅图片纠正系数,进而补偿原始图像,减弱曝光差异导致的拼接痕迹。实验结果表明,该算法不仅能快速地消除了拼接缝隙,而且使得整个全景图更自然流畅。

Long image sequences with very different exposure in source images would case the stitching seams more obvious. To address the problem, a new color correction algorithm is provided. The proposed algorithm calculated the color correction coefficients for every source image by a global correc- tion function in Ycbcr color space to compensate source images and weakened the stitching seams. The experimental results show that the correct correc- tion algorithm not only can eliminate the stitching seams fast,but also can make the panorama image more natural.
