semantic3D数据集

这个数据级别的训练集有一个小BUG，是这个neugasse_station1_xyz_intensity_rgb.7z， 解压之后的名字是station1_xyz_intensity_rgb.txt，自己最好手动去修改成neugasse_station1_xyz_intensity_rgb.txt，不然跑一写程序会存在一些问题

提供了两种数据：

1、semantic-8，包含8类东西（1: man-made terrain, 2: natural terrain, 3: high vegetation, 4: low vegetation, 5: buildings, 6: hard scape, 7: scanning artefacts, 8: cars, 0: unlabeled points）。0lable 没有ground truth也不应该没用于训练。训练集和测试集各15个，点云总数超过10亿， 所以作者怕你的算法受不了，所以提供了一个压缩版本的

2、reduce-8训练集和semantic-8一样，测试集只是semantic-8的一部分。测试集是0.01m的均匀下采样.
