基于激光点云的大型文物景观三维重建方法

3D Reconstruction Method for Large Scale Relic Landscape from Laser Point Cloud

  • 摘要: 为了提高景观模型的可靠性,将球体标靶作为点云配准的约束条件,同时引入带有绝对坐标的标靶作为点云转入大地坐标系的起算数据,并将经过纠正的数字影像纹理映射到点云上,从而生成完整的三维景观。云冈石窟的试验证明了该方法的有效性。

     

    Abstract: Laser scanning point cloud affords an efficient way to build the 3D model of relic landscape.The traditional method is to register the point-clouds from different views one by one and gain the whole landscape of point-cloud in the same coordinate system.Because of the existence of noise from laser device and the influence of accumulative errors from register work,the method mentioned above is difficult to realize the accurately register.For improving the reliability of the landscape model,a method is introduced that makes the sphere target as the restrictive conditions in the point-cloud register work,and simultaneity importing planar target having absolute coordinate for transforming the whole point-cloud model to a geodetic coordinate.And then,the digital image texture of differential rectification is mapped to point-cloud model for building an integrated 3D landscape model.The experiment in Yungang Grottoes demonstrats the validity of this method.
