| 摘 要： | 在已有的全景图像拼接方法中,无论是柱形还是球形,都需要很多人工操作,这使得工作效率低下并且成本高昂.为了实现自动化,提出一种新的拼接方法:把拍摄的照片用一种按纹理中心点进行的球面映射方法来进行纹理投影,考察这样投影后照片的重合带图像,以重合带的差值图像灰度累积平均值为评价参数,计算出纹理中心的最佳位置,并以该位置为拼接条件生成全景图像.该算法适合球形全景和柱形全景图像的拼接.该算法可使程序的全景图像拼接过程完全自动化,从而降低全景图的制作成本.

| Abstract: | Whether the panorama was cylindrical or spherical,much manual operation was necessary to use existing stitching method,which was inefficient and expensive.In order to realize stitching automation,a new algorithm was presented,where the photos were projected with a spherical mapping according to the textural center.After the image with superposed bands being after projected and surveyed,and then taking the gray accumulation average of the superposed differentiating image as an estimate parameter,the optimal ... |
