Now I have a Livox Horizon Lidar,and I can use the Lidar to displays the point cloud image of the current shot, but I don't understand how to mapping a omnibearing map. Second, when I played the rosbag(parking or road) ,the amount of point is so small. different from the picture in readme

I found that whether i run bag or mapping, i can only display the first screen and will not be updated after that. In the terminal which I input roslaunch loam_horizon loam_livox_horizon.launch , it will display

I have the problem, how do you solve it? Thanks.

hi @chewing-void ~This is because the laserMapping node is dead, so the point cloud will not accumulate. Did you start roslaunch in ubuntu 16.04?

I run the code on ubuntu16.04. Other environments are as follow： ceres:1.14.0, PCL:1.9.1, Eigen:3.3.7. Does PCL version cause this error？

PanZhichen commented 4 years ago

@SherlockHermes This should be the key to this problem，you can test with PCL 1.7, good lunk!

Thanks for u help.I run the code on ubuntu 18.04 . Should I install 16.04 ?

SherlockHermes commented 4 years ago

@PanZhichen u r right，when I change the PCL version to 1.7, the results get better. Thanks!

@PanZhichen When I change the PCL version to 1.7 , some error happened. It means that ubuntu 18.04 maybe not install PCL 1.7.
