Drawing PointCloud2 in the World Coordinate System by Rviz

asked 2021-10-01 10:42:17 -0600

Q gravatar image

I'm drawing PointCloud2 with rviz on melodic. They are superimposed based on a long decay and a tf based on the exact sensor position (with about 200hz).

However, there was something wrong on this drawing after an update the other day. All points during the decay period are drawn based on the latest tf now, so sensor movement is not considered.

This only happens in PointCloud2 and LaserScan is correct as before the update. (It remains in the correct world coordinate system because it is drawn based on the tf of the corresponding timestamp.) This is happening in every PointCloud2 and is normal in every LaserScan.

Did any recent updates cause any bugs?

I found the cause.

I checked the source code and there was no problem with Rviz built from the latest code. This issue was maybe resolved by the following revert:
