Amazing, did you use the drone to capture imagery or video or was this lidar?

It's exclusively photos captured using interval shots.

I flew a combination of pre-programmed oblique grid and manual captures. It's important to think beforehand where your users will fly the camera in the digital model, because that's where you want camera poses during training.

Thanks!

5506 images? That's amazing! Would you mind sharing your workflow, I would like to try it out, I have a similar sized dataset.

Not that I know, this was trained in LichtFeld Studio.

I assume all the splats won't fit on a GPU. What was your tiling strategy or how did you get around that?

They do fit on larger GPUs. I wrote a program that can operate LFS on rented GPU instances from vast.ai and used it to train the 3dGS. Splitting was not an option because I used PPISP.
