fid does not match frame

[cdfan0627]

您好，我在用NeRF-DS dataset training的時候發現，每個frame的uid與fid不匹配，如下圖，可以請問一下原因嗎


在as_novel_view的class理論上uid = 54 ，fid應該要等於54 / 845 = 0.064才對，不應該是上面的0.3290

Hi, thanks for your interest.

I found that in NeRF-DS dataset, the uid is not consistent with the actual frame id. So I used the image name as the fid to obtain the right sequence, which is shown in the code here.

可是NeRF-DS dataset 的 fid不是定義在這裡嗎https://github.com/ingra14m/Deformable-3D-Gaussians/blob/main/scene/dataset_readers.py#L459

sry for the wrong link. What I want to say is that the uid in NeRF-DS dataset is not consistent with the actual frame id. That's why in metadata.json, there is a dedicated field defined as time_id.
