使用流程:使用 官方数据集 handle.bag
roslaunch lvi-sam run.launch
结果图:
LVI-SAMErroPic
如图轨迹为锯齿状形状,再运行时,轨迹,地图等会出现很大漂移。代码从库上拉下来没有做任何更改,请问是需要单独配置什么参数吗???

我也是这样,然后我把数据集播放速度调到0.5有明显改善:rosbag play -r 0.5 handheld.bag
但这应该不是正确的解决方法,因为我发现我的终端报错:[lvi_sam_visual_odometry-9] process has died
我猜测是视觉里程计没有起到作用,仅仅依靠激光部分工作,由于点云的稀疏性,在后端和回环部分无法矫正偏移。
