Conclusion:

1. the density of the maps from SR and the ground truth is comparably the same. In other words, the density is improved compared with the 16 channels data.
2. the accuracy of the SLAM is pretty similar.
3. the accuracy of the map still needs to be enhanced. More challenging environments should also be tested.
