What do you mean by Translation errors are scaled by 100.?
I want to know the unit of translation errors?
Is it meter?
Have you encountered any peculiar phenomena when using Umeyama's method? For instance, in certain situations, have you observed significantly large distances between the estimated poses aligned using Umeyama's method and the ground truth poses?
Thanks for your great job! During reading your code, I have a problem can't figure out.

Why don't you use camera_cords_grid_3D
directly, but transfer to camera_cords_grid_2D
before put in warp_mlp
? Is that necessary?
Thanks again! :)
您好,感谢您的工作。
我在复现的时候遇到了一些问题,有关warp网络的初始化,和它的激活函数。想问一下是怎么设置的?
再次感谢!
Hi, thanks for this amazing work and publishing the code alongside it!
Right now, you don't specify any license for the code in this repository (as far as I can see) - is this something that you could add so that people know how they're allowed to use the code?
All the best,
Stefan
Hi, I noticed the experimental results of BARF in the paper are very different from that in the original BARF paper. I wander if it is because the parameter setting ?
training: 0%| | 0/200000 [00:00<?, ?it/s][val] loss:2.060e-01

The progress bar didn't move for three hours!
Is there a way to get vertex colors while extracting the mesh?
Thanks for releasing the code, I really appreciate your work!
I tried to run the code with l2g_nerf
model, and the value of taylor series shoots to +/-infinity in camera.se3_to_SE3
.
It seems that this is caused by the warp_mlp
giving very large (about 100~1000) se3 values without initialization.
How should I initialize warp_mlp
and warp_embedding
? Or did I miss anything?
Thanks :)
Hi! Thanks for your awesome work ! I want to know when the code will be released . I can not wait to test your wodenful work!!!
