kitti 00地面过滤过多

[zqlee-ronghui]

Hi, 张博，感谢开源。我在使默认参数处理kitti 00数据集时，发现地面过滤过多（见下图），这种情况要怎么处理呢？

我记得demo 我给的也是00 你运行的是哪个commit呀？

仔细看有时候确实会有地面的去除，但是我看过不会像你截图这样这么多来着.....

还有另一种方案 就是和我octomap w. gt 那篇一样，对地面做单独处理 （不过这样只针对驾驶场景比较友好

感谢回复，我在这两个repo：https://github.com/Kin-Zhang/dufomap (commit: 4f1cdbfa533bfebe56664b987ecf9eb246f80c27), https://github.com/KTH-RPL/dufomap (commit: 5b2884f6c8efa3f035dd538a68e72296dc205ca2) 都测试过，结果都跟上面一样
