@zfc-zfc Hi! Thank you so much for the great work. I hope you can help me.
I'm using a VLP16 LiDAR and a PX4 IMU and I've setted up the package with Docker. Below I attach a video showing what happens in my setup.
On the left terminal I just have the connection from my PC to a Jackal robot which has the VLP16 and PX4 mounted on it (the process running is just a
roslaunch
to enable the IMU). On the right terminal I have the Docker container running in which I exported theroscore
of the Jackal robot and for that reason Iecho
the LiDAR and IMU topics that I need.Then I run the actual package with the
velodyne.launch
file and you can see what happens in the video. I'm using real time data, not a bag file. Keep in mind I did not move the entire robot, keeping the LiDAR and IMU static. The initialization just starts to fill and on rviz it displays strange behaviour:423d621f-29eb-4a29-b7b5-5bba753e51b2.mp4 I have read Issues #9 (I changed the parameters that you advised to change, below I attach a picture my
velodyne.yaml
file); #43 (I verified and is shown in the video that the angular velocity of input seems to be in rad/s).If you could help me it would be much appreciated. Thank you very much in advance!
My suggestion: 1. cut_frame_num = 2; filter_size_surf = 0.2; filter_size_map = 0.3 If the above modification still doesn't work, please try a larger scene.

Hi! I really appreciate your response, and I apologize for the late reply.
I tried your suggestion of changing those parameters, but it didn't help. Then I tried a larger scene, and it actually didn't immediately fill up (the bars of percentage) like in the video that I showed in my issue. It remained at zero percent across all axes when the system was static, but as soon as I tilted the LiDAR+IMU system, all the bars immediately filled up :(
I do have some sort of error that I am not familiar with, and I don't know if it is jeopardizing the process. An image follows:
Is this error something that I should fix? Or any other suggestions?
Thank you very much for your time!
