Cartographer建图提示Filter dropping message: frame 'laser_link' 解决方案
-
问题描述:使用ROS2 Cartographer进行仿真建图的时候出现的错误,RVIZ2中图正常,但是map和base_footprint姿态差距非常大。
同时终端提示以下内容:
[rviz2]: Message Filter dropping message: frame 'laser_link' at time 322.559 for reason 'Unknown'
系统信息如下:
- Ubuntu20.04
- foxy
- cartographer: foxy分支
- cartographer: dashing分支
- Gazebo11

@小鱼 问题定位与解决方案:
使用rqt_tf_tree查看tf是否正常,发现map到base_footprint之间时间差距非常大。
问题原因:cartographer启动时为设置use_sim_time为True。
解决方案:
在launch后增加use_sim_time设置使用仿真时间源。
use_sim_time:=True
正确的TF如下:
