应该是这两个地方有问题:

  1. 检测到回环就报错,应该是globalmap的输出文件夹位置的问题,参考这里:编译fast_lio时提示没有pcl_catkin #14
  2. 检测到回环后不进行变换,是pcl与ubuntu的版本问题,去掉DCL-FAST-LIO/CMakeist里find_package{pcl_catkin},直接用ubuntu20.04的pcl1.10,参考这里:pcl_catkin && catkin build dcl_fast_lio error #18

您好,我遇到了抛出 'std::length_error' 实例后调用的终止what(): vector::reserve这个问题,并且按照您说的使用本地的pcl1.8.1库,但是仍然会遇到遇到回环即停止的问题

请问您解决这个问题了吗

@youhha 为什么机器人之间显示了闭环边但是却没有进行闭环优化,并且机器人自己本身的序列也没有进行闭环优化
