激光雷达的安装高度是多少？

Hi, what a great dataset!

Could you plz tell me what is the relative distance of the LIDAR coordinate system's origin to the ground? I have searched the official website and paper but didn't find this information.
I look forward to your reply. 
请问是否可以告知激光雷达坐标系原点距离地面的相对高度为多少？查找了官网和paper都没有找到这个信息。
期待您的回复。
