摘　　要：球面全景图可以任意改变观察视角,在场景的构造中具有重要的作用。针对球面投影过程中存在的变形问题,用双线性插值算法求出变换结果图像中的像素值,较好地解决了变形问题。在此基础上,采用基于灰度相关,由粗到精的图像拼接方法进行拼接。实验结果表明,经插值后进行拼接的球面全景图像能达到较好的视觉效果。The spherical panoramic image which plays an important role in scene construction can change visual angle discretionarily. In order to solve the distortion problem caused by spherical projection, the algorithm of bilinear interpolation is proposed to get the pixel value of transformed images. A stitching method which is from coarseness to extract and is based on gay correlation is applied to image stitching. The experiment proves that the spherical panoramic image which is stitched after bilinear interpolation can achieve good vision effect.
