Lensphoto系统在3维重建中的应用及若干问题探讨

对多基线数字近景摄影测量理论在3维重建应用中的注意事项及遇到的若干问题进行了初步探讨。文章以青铜塑像为例，对3维重建中外业布设控制点时的注意事项进行了阐述，并针对后期点云处理和纹理粘贴时遇到的问题进行了探讨。事实证明，该方法在3维重建中不仅具有较高的精度，同时还能以更经济的方法迅速得到同3维激光扫描相媲美的点云数量，为保护文物的3维重建提供了有效的方法。

The Discussion of the Problems and Application of Lensphoto System in 3D Remodeling

This paper discusses some problems and matters for attention of multi - baseline digital close - range photogrammetry in the application of 3D remodeling. Taking the bronze statue as an example, this paper elaborates some matters to consider in the process of arranging control points in 3D remodeling, and discusses the problems in the process of handling point cloud and pasting texture. It is proved by the facts that this method is not only high in precision but also capable of obtaining equally large quantity of point cloud as 3 D laser scanner in a cheaper way and provides an effective method of 3 D remodeling for protected cultural relics.
