壁画数字化是敦煌研究院壁画保护的重要工作，目前，由于壁面不平、相机畸变等因素造成拍摄获取的壁画大小不一，有一定程度的几何形变，给壁画的拼接带来一定困难，同时，加大了拼接后的整幅壁画的形变和误差。本文通过修正相机的镜头畸变，改善单站壁画照片的形变，优化了自动拼接的效果，不仅使得图像拼接自动化程度提高，也大大降低了自动拼接的错误率。

Mural digitalization is an important part of the conservation work of Dunhuang Academy. Because of the irregular shapes of cave walls and distortion of camera lenses, the photos captured in caves show some geometrical distortion, which causes problems in the image mosaic and greatly decreases the quality of the mosaic. In this re- search, camera lenses were corrected to reduce the distortion of images and then optimize the image mosaic, not only improving the quality of the automatic mosaic, but also decreasing mosaic errors.
