Visualization error

Closed this issue 5 months ago · 5 comments

Hello, I used your code, but in the image display, I found that it did not achieve the effect presented in your paper. Instead, I had terrible results.

Can you tell me where the problem is?

The picture below is the result after training for 70k steps

Hi, I was wondering whether this is caused by this transformation, mentioned by another user: here. Could you try to set it to all 1 to see?

Basically, make sure that the camera poses are right for the nerf rendering.

Hello author, after I modified the first point you mentioned and checked the camera parameters for nerf rendering.

But I still get the wrong rendering result below

Could you please tell me what else I should check?

Hi, how many camera views do you use?

And could you try to set BC loss to be 0, and check whether only rendering loss could work?

Well，I have set the BCE loss to 0.0001. And I only used one camera. At first, I thought it was a coordinate system mapping issue, but I carefully checked the code to ensure the coordinate systems are consistent, yet the problem still occurs.
