CSF的第一个正式引用终于出现了，是一篇机载点云地面滤波的综述文章(Chen, Z.; Gao, B.; Devereux, B.State-of-the-Art: DTM Generation Using Airborne LIDAR Data. Sensors2017, 17, 150.)，评价是

The results proved that the CSF achieved satisfactory accuracy in most terrain and
the post-processing significantly enhances the performance of CSF in steep terrain.

期待后面引用雪崩式爆发。

另外，python下也可以使用CSF了，见项目最新日志。https://www.researchgate.net/project/CSF-Ground-filtering-of-point-cloud-based-on-Cloth-Simulation
