Using AMCL for navigation with hector slam

edit

Hi guys, I'm trying to navigate on a given map(built by hector slam), and the odometry is only supplied by Lidar by using hector mapping (didn't use any other extra sensors ), and I'm using raspberry pi 3B to publish the /scan data to my computer(RViz, navigation, mapping). Now, when I use AMCL for navigation, there're some problems showed up(the particle seems weird), I search a lot but still don't know where is the problem, is there any one can please help me to check the problems, thank you very much!! (here is the link of picture:AMCL_problems )
