Reviewer 2 Report

This is an interesting topic, some comments are as follows:

（1）Please describe your contribution more clear,  if just deploy the Lidar on the mobile robots, the novelty is not strong, based on this platform, please give the more description about the new problem and the contribution.   

（2）The  author  mentioned that  “To achieve  such a goal, the measurements captured by the moving LIDAR are  transformed, interpolated, and  compared to a reference state of the surrounding.”How to transform， and  how  to interpolate， please give more details.

（3） In the simulation, does the  parameter  of the simulated person  effect  the data  acquisition, please give some comments.

（4）The proposed method just use the simulation to verity the proposed method,  the reviewer suggests that  the author can  carry out the field experiment to verity the proposed method if condition allows.
