ROS Navigation Stack

start from 6.12
https://zhuanlan.zhihu.com/ros-nav
Want to nav using skecthed or emergency map(not accuracy map) originally, but at last it's deprecated for some reasons...
Now it's just a repo for record.

sketched map两篇论文的思路:

  • 修改下粒子滤波的过程,将pose(x,y,theta)多加两个
    扩展为pose + (a,b),也就是局部拉伸变形
    里程计的距离也拉伸下

论文的问题:

  • quick change in the scale,因为scale不像pose一样
    pose有测量保证单步之后是个高斯分布
    scale也学人家pose,认为是原来的scale发散下
    那变化快了localization丢了
