摘　　要：当前图像平滑方法对尺度、视差和光照变化较大的柱面全景图图像拼接部分的处理效果不佳。为此,提出一种新的柱面全景图图像拼接中图像平滑的虚拟现实技术,依次对待拼接源图像进行柱面投影,获取不同柱面图像序列,求出柱面平移量,通过融合获取柱面全景图像。将最小灰度差异点看作拼接点,通过调整灰度差,经拼接缝定位与拼接缝消除两个阶段实现图像平滑处理。将完成平滑处理后的柱面全景图像生成虚拟现实场景,应用于不同领域。实验结果表明,采用所提方法进行柱面全景图像拼接中图像的平滑处理,在尺度、视差和光照变化较大情况下仍可达到无缝拼接;且拼接部分图像质量和完整性较高。The current image smoothing method has poor processing effect on the cylinder panoramic image mosaic with larger scale,parallax and illumination. Therefore,the virtual reality technology is an image smoothing cylindrical panoramic image stitching in the new order,the mosaicked source image using cylindrical projection,obtaining different cylindrical image sequence,calculate cylindrical translation and cylindrical panoramic image acquisition by fusion. According to the adjustment of the gray difference,the image processing is realized by adjusting the difference of the gray level,and the two stages of the seam location and the joint are eliminated. It will be used to generate the virtual reality scene after the smooth processing of cylindrical panoramic image. The experimental results show that the proposed method for image smoothing cylindrical panoramic image mosaic of the disparity in scale,and illumination changes under the condition of large can achieve seamless,and the splicing part image quality and high integrity.
