测试建图遇到的问题整理

问题一:
 
设置完机器人的urdf模型,再运行slam建图程序出现一下报错

Warning: TF_OLD_DATA ignoring data from the past for frame imu_link at time 1.56379e+09 according to authority unknown_publisher

解决方法:
 
经检查发现是tf变换冲突,本来启动imu的launch文件里面写了tf变换,这跟urdf里面设置的重复了,注释掉启动imu的launch文件中的tf变换语句后,程序运行正常

问题二:
 
测试karto算法建图时,发现rviz中有一系列连续的黑点,其为机器人已走过的痕迹,之前在tb3上也遇到过这样的问题
