Hector-mapping error: ‘lookupTransform xxx to xxx timed out

asked 2021-03-07 05:01:58 -0500

I was using the Livox lidar to provide the raw pointcloud msg(the frame_id here was changed into 'laser') and then use 'poincloud_to_laserscan' module to publish the topic /scan. And I also published the tf tree in the launch file with:

node pkg="tf" type="static_transform_publisher" name="baselink_to_laser" args="0 0 1 0 0 0 laser base_link 100"

So the situation is that, I have got the /scan topic, and provided the tf from 'laser' to 'base_link'. It supposed to work well but I got the error:

[ INFO] [1615110469.391471468]: lookupTransform base_link to laser timed out. Could not transform laser scan into base_frame.

image description (Sorry for the poor picture quality )

The tf tree is just base_link->laser

It really confused me, so finally I come for help, any suggestion well be fully appreciated!!
