hi, Thanks for your excellent work in laser driver here.

I encountered a problem using your laser_node package to get the data from sick LMS511lidar, when I scan a wall, the result should be a line in rviz, but it shows a circle which could be seen as follow: image

do you have any ideas about this?

could this be a problem related to your laser_driver?

Thanks!

Hi, @pangfumin , so glad to hear from you.

I will send you the bag file at about 12:00 today containing the /scan topic.

Thanks a lot!

Hi, @pangfumin , here is the bag files containing two parts:

  1. scan the wall in my lab by 360 degree rplidar, the result in rviz is right

rplidar

  1. scan the wall in my lab by LMS511(-95 degree ~95 degree) using your laser_node driver. but the result showed in rviz is not right, the result should be a line in rviz, but it shows a circle which could be seen as follow: lms511

this is the bag file

containing the /scan topic using rplidar and using LMS511 with your laser_node driver respectively.

Actually, the point in the two red Dashed box in the picture below should be the same(a line represent the wall) . default

Hi, @pangfumin .

The parameters of LMS511 are listed as following which I got from the terminal when I run the laser_node :

1.frequency: 50Hz 2.resolution: 0.5 degree

Thanks Best regards
