LiDAR rotates and moves alone in a mapping environment, even though LIDAR is fixed in reality. #282
Description
Hello, I'm doing LEGO-LOAM using Ouster LiDAR. I'm using ROS melodic in the Jetson nano developer kit.
My current problem is that LIDAR rotates and moves alone in a mapping environment, even though LIDAR is fixed in reality. If you look at the attached picture, you can see that LiDAR is rotating alone and drawn according to its path. However, in reality, LIDAR was fixed and did not move.
It works normally when I turn on LiDAR with ROS and when I turn it on through Ouster studio, so I don't think it's a problem with LiDAR itself. Also, the same issue happened when I used TX2 board and velodyne LiDAR to do LEGO-LOAM. I've been wandering around with the same issue for weeks. I'd appreciate it if you could tell me how to fix this problem.
