The problem of bigger scene reconstruction #17

Open huangqiusheng opened 5 months ago

huangqiusheng commented 5 months ago

Admirable work! When I try to reconstruct a 198-frame waymo dynamic scene, the reconstruction effect is very poor. It seems that it can only succeed under 50 frames. Fine-tuning some hyper-parameters does not solve this problem. Please give me some advice, thanks！

Can you share the config and scripts you used on waymo scene? I want to use PVG on my waymo dataset. Thanks a lot.

Thanks!

How do you convert the raw .tfrecord waymo data to kitti format? I just use the sciprts provided by Waymo_kitti_converter, but the results can't be used directly.

@huangqiusheng hi, you could try to add "fix_radius: 10.0" to the waymo config to alleviate this problem. This parameter will fix the threshold controlling whether a point is going to split or clone (otherwise this threshold will grow as the scene becomes bigger and lead to a "under-split" case).
