bds.npy in Dataset

[SuzyZhao0417]

Hi! Thanks for your great work. I want to test my own data but I don't know how to get bds.npy, could you please tell me what's about?

Hi! Thanks for your kind words!

In the first static scene reconstruction stage, we follow the LLFF code (https://github.com/Fyusion/LLFF) to preprocess the calibrated results generated using COLMAP. This step will generate the poses_bounds.npy. It mainly contains the camera poses and bounds of the scene.

Then, to ensure the same camera poses and bounds for the second few-view dynamic scene reconstruction stage, we store the poses and bounds for the few view camera views when we use the poses_bounds.npy in the first stage. This step will generate the poses.npy and bds.npy.

Hope that clarifies. Thank you!
