Cultural Relic 3D Reconstruction from Digital Images and Laser Point Clouds

This paper proposes a method to combine the digital images and Laser point clouds to reconstruct the 3D model of the archaic glockenspiel. All the stations of the Laser point clouds are connected according to the ICP arithmetic. Then image matching is used to register the high resolution digital images and the Laser synchronous images to gain the corresponding texture of the Laser point clouds. Finally, build TIN of the entire point cloud model and remove the redundant points according to the angles between the normal vectors of the local surface areas. The method of this paper is simple, accurate and quick to rebuild the 3D model of an object. It is very meaningful in cultural relic protection and exhibition. The effect is obvious.
