how to find the true pos?
in a project, we use amcl move_base and odom laser . the odom must have error and the amcl can product the pos , through tf to tell the robot pos.
and when we run it some times .
the odom will product 1meter's error.
when we close the robot.
we must save the pose to file. when I restart the program , we can read the pos to rviz.
we use the /map /odom to cal the pos but ,it always product some error. so i use tf /map /base_link and we get some error too.
anyone can help me ? how to cal the pos?
