Have you tried Patchwork++ on nuScenes? about patchwork-plusplus

No..

Thank you for having interest in our work :)

Unfortunately, I haven't run Patchwork++ on nuScenes yet.

Well, at first, I need to say that it is very difficult for me to say which one directly occurs such result because the picture is not enough to find out the problem. However, I guess that the sparsity of point cloud due to less beams won't let such result since the false positive points(red points) in your picture are dense enough to be estimated as a proper ground plane in my thought. If the divided patch is far from the sensor origin, the sparsity can be a severe factor which results in a poor plane estimation. I can suggest you to check the uprightness, elevation, and flatness values of those wrongly-estimated planes and compares that values to the thresholds of them, respectively.

@zwqnju, have you succeeded at tuning the parameters for Nuscenes dataset?
