Hi, thanks for your amazing tool.
Hello, I would like to ask you some questions. I am using the KITTI dataset, sequence 00. I followed your steps, but the point cloud is not displaying. What could be the reason for this?

When I added car points, the result is as shown in the image below.

calib.txt and poses.txt were downloaded from the official KITTI website. The settings in settings.cfg are as follows

What should I do ?

Just for reference, you should get for sequence 00 the following output:

Can you check that the velodyne folder contains 4541 files, where each .bin file is approximately 2 MB?

Yes, each .bin file is approximately 2 MB in size. If the .bin files contain no data, the car points should not be loaded.

the "car points" are simply the eco vehicle points that are filtered while loading.

Can you simply use the poses provided with our labels? I guess that it not be a big difference, as the initial pose is anyways identity, however, one never knows.
