How to run with pyLiDAR-SLAM on KITTI-corrected? about ct_icp HOT 12 OPEN

Hi,
I'll get back to you on this I soon as I can (Hopefully by the end of the week) !

Thank you sooooooooooooo much! This is really important to me!

@samsdolphin Did you get the help about this?

Hi, sorry it takes a little more time than expected.. Still on this

Hi @estevancandido, I managed to run it using the script below, but the results are worse than expected.

python3 run.py dataset=rosbag dataset.main_topic=velodyne_points dataset.file_path=/media/sam/T7/KITTI/06/06.bag slam/odometry=ct_icp slam/loop_closure=elevation_image slam/backend=graph_slam device=cuda:0 num_workers=8

So I write a scan-context-based loop closure ROS node and publish the point clouds and the corresponding poses generated from ct_icp in another node. If you wish, I could open-source it. You can tune the parameters by yourself. The odometry results are improved from the ct_icp (without loop closure) and are much better than those using the pyLiDAR-SLAM script above.

Hi,@samsdolphin, it's wonderful that you have written scan-context-based loop closure code. I'm wondering if you could open-source it. I would be very grateful.

@Forrest-110, sure, give me some time, maybe this weekend.

@samsdolphin Thank you so much!

Hi @Forrest-110, I have created a repository called sc_ct_icp which functions as described above.

Hi, @samsdolphin . Sorry to bother you again.

I'm also attempting to reproduce the loop closure results using pyLidar-SLAM, but it seems that currently ct-icp python binding is broken. I tried the old-master version of CT-ICP, but when I run pyLIDAR-SLAM using "python run.py slam/odometry=ct-icp ...", it says "In slam, Could not find 'slam/odometry/ct-icp'". It seems that the config file of CT-ICP in pyLIDAR-SLAM is missing.

Do you have any ideas? Thanks again for your kindness！

Hi @Forrest-110, I am sorry, I don't have any spare time on this issue. I think as long as you can run the original ct_icp code, you don't need to care too much about using pyLiDAR-SLAM to perform the loop closure.
