SHIFT_COOR? #5
Comments
Yes. Different datasets have different denfination of original point. I shift the point clouds to match the defination in waymo: the original point is put on the road plane. This parameter is set acoording to observation. |
I use the config pvrcnn_old_anchor_ros.yaml, and I can't reproduce the paper result。I use 1/5 trainset of waymo dataset to pretrain as I can train within oneday with 1/5 trainset, and direct test checkpoint_30.pth on kitti dataset。 but the iou=0.5's result is relative normal: do you have any advise for me to find the reason?does 1/5 and 1/2 trainset have so much different on result? |
what's more, I use waymodataset1.2, and I use toplidar and four blind(补盲) lidar。 |
Hello, |
OK,I will try |
it looks like that the cfg file pvrcnn_old_anchor_sn.yaml and pvrcnn_old_anchor_ros.yaml are the same......😭 |
I use cfg pvrcnn_old_anchor_ros.yaml to train, with batch size 40(8gpu),and test use cfg pvrcnn_st3d.yaml。after evaluation the checkpoint_[16,30], total 15 checkpoints, the best result I get for 3d ap(iou=0.7) is 25, I'm now evaluation the before checkpoint, checkpoint_[0, 15] |
unfortunately, the checkpoint_[0,15]'s result is more low, so the total 30 checkpoints's best result for 3d AP(iou=0.7) is 25. |
I am quick sorry for my mistake. I will fix this problem quickly. I think we can test the testing code first. You can send me an email, and I will send my pretrained model to you (due to waymo license, I cannot make it public). If the problem does not lies in the testing code, I will then try to use 1/5 data and v1.2 data. Don't worry about that~ |
already send you a email to paper email address。 |
@AndyYuan96 Hello, what's the result of your reproduction? Is it close to the effect in the paper? |
yes, now I can reproduce the result, some notes:
|
Thank you for your advice, i will try it. |
Could you share your results and CONFIGS as you reproduce the result. I have tried many times, but the performance was still far away from the paper |
Hello @AndyYuan96 , I am also trying to reproduce this work and met some issues. I use spconv 1.0 and pcdet 0.2, I can achieve 65% on waymo for pre-trained step, then I go to the self-train step. However, after that, I can only get this result: bbox AP:86.0902, 76.7667, 76.7454 I dont know why the AP for threshold 70 and 50 can have such a large gap. Could you give me some help? My email address is 18916835036@163.com or you can just reply here (depends on your convenience!), thank you very much! |
Hi,jihan, the parameter SHIFT_COOR in cfg file pvrcnn_old_anchor_ros.yaml means what? does SHIFT_COOR is the lidar position difference among different dataset?
