目前一直卡在map initializing, odometry not stable, resetting...这个阶段,这个应该怎么做?

初始化需要保证起始几帧不能剧烈运动,如果是手持的小线束雷达,把关键帧间隔调成0.5 或者1m

谢谢,现在初始化解决了,但是保存地图又遇到了问题...我目前是用rosbag_proxy播包的,建图和编辑都没问题,但是保存地图的时候创建不了image文件,因为我的相机name是http://开头,文件名不能包含/,所以现在保存不了地图,播包的时候还会有当前点云闪现的问题,虽然不影响建图,但是可视化效果不太好,而且bag包播完停止后预览界面的当前点点云会不停闪现,请问这两个部分可以怎么改进?我目前改了保存图片的文件名,但是定位读取地图的时候又出现cv宕机的情况

一定要保存图像吗,可以先不把图像加进去呢

嗯嗯也行,主要是想试试词袋重定位..rosbag_proxy里的restream一定要有吗?我怀疑是这个引起的点云跳变
