中文摘要：

针对地面散乱点云由于数据稠密性和不规则性难于获得扫描线信息这一问题，提出一种地面三维散乱点云扫描线信息生成方法。首先利用三维体素对散乱点云进行重采样，然后对重采样的点云进行扫描光线重建，最后将扫描光线按照角度划分从而获取地面散乱点云的扫描线信息。通过实测点云数据进行实验，验证了该方法的可行性。

英文摘要：

It is hard to generate scanning line information from scattered point clouds because of the density and irregularities. To this point, a scanning line information generation method based on terrestrial scattered point cloud is proposed. The resampling process based on voxel grids is performed to scattered point cloud firstly, then scanning rays are reconstructed, finally, scanning line information is generated through an angle dividing method automatically. Through the experiment of measured point cloud data, the feasibility of the pro- posed method is verified.
