Abstract壁畫數字化是敦煌研究院壁畫保護的重要工作,目前,由于壁面不平、相機畸變等因素造成拍攝獲取的壁畫大小不一,有一定程度的幾何形變,給壁畫的拼接帶來一定困難,同時,加大了拼接后的整幅壁畫的形變和誤差。本文通過修正相機的鏡頭畸變,改善單站壁畫照片的形變,優化了自動拼接的效果,不僅使得圖像拼接自動化程度提高,也大大降低了自動拼接的錯誤率。

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 research,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.
