基于激光扫描和高分辨率影像的文物三维重建

提出一种新的激光扫描点云与数字影像结合的文物三维重建方法。利用格网板进行数码相机的标定获取影像的内方位元素；利用激光扫描数据，建立三角网物体表面模型；利用人工选取控制点，进行单片空间后方交会，获取影像的外方位元素；将三维表面模型投影到影像对象，利用影像匹配在现有的三角网内部继续通过影像匹配增加同名点，从而进行三角网的细分加密；最后通过OpenGL纹理映射建立带有逼真纹理的物体三维表面模型。

Three-dimensional reconstruction of antiques based on LIDAR and high-resolution images

In this paper we bring a new laser scanning point cloud and the combination of digital imaging method of three-dimensional reconstruction antiques. The use of grid plate calibration of digital cameras to obtain images inside the orientation element; the use of laser scanning data to set up triangulation surface model; the use of artificial control points selected to carry out single-chip space resection to obtain images of the exterior orientation elements; will be three-dimensional surface model to the image of the projector, the use of image matching in the existing internal triangulation to continue to increase through the image matching points of the same name, which carried out a breakdown of the triangular network encryption; finally set up through the OpenGL texture mapping texture objects with realistic three-dimensional surface model.
