Ok. Thank you for your answer.

2020-08-22 06:55:07 -0500 marked best answer Rejected loop closure 93 -> 173: Too large rotation detected!

Hi,

I am doing 3D mapping with Kinect 360 camera using RTABMAP. Mapping starts well and then I start getting this two errors:

  1. "[ WARN] (2020-07-22 14:50:09.654) Rtabmap.cpp:2144::process() Rejected loop closure 93 -> 173: Too large rotation detected! (pitch=0.000000, yaw=0.000000) max is -1.628242"

  2. [ WARN] (2020-07-22 14:57:33.872) Rtabmap.cpp:2144::process() Rejected loop closure 57 -> 99: Not enough inliers after bundle adjustment 0/20 (matches=70) between 57 and 99

They occur in between lots of successful readings. For moving a robot I use:

rostopic pub -1 cmd_vel geometry_msgs/Twist '[0.1, 0, 0]' '[0, 0, 0]'

and for rotation I use:

rostopic pub -1 cmd_vel geometry_msgs/Twist '[0, 0, 0]' '[0, 0, 0.1]'

I am using Pioneer 3-AT with ROS Melodic.
