| Abstract: | This paper introduces the approaches producing the digital orthophoto map(DOM) of Yungang rock cave using 3D laser point clouds and digital images.The 3D point clouds and digital image are acquired in synchronism by laser scanning and digital photography.The mapping model is built between the point clouds and digital image.The true chromatic model may be realized with the help of endowing the texture attributes of digital image into the 3D point clouds model.The results achieved here are very important for protecting and restoring historical and cultural relic. |
