The object of post-scanning data processing is to reconstruct surface models from 3D point clouds.

后扫描数据处理的物体将重建来自 3D立体点云的表面的模型。

Say for example, you have light enter a point on a surface, you then have the light continue to go through the object until it hits a back face, i. e. , it leaves the object.

譬如说，你轻点就进入了表面然后根据你继续办理，直到碰到一回面对象，即离开物体。

The measurement of scattered point cloud data is the foundation of surface reconstruction of a 3d object.

散乱点云数据的测量是三维物体曲面重建的前提和基础。

The laser would only singe the surface of an object in space, but that tiny burn could still help point it downward, Dr. Campbell says.
