No Lidar, Only photos were captured with Insta Ace2Pro. Gaussian was trained by MipMap Desktop.
The performance from pure photos alone in a weak-feature indoor environment is genuinely surprising — no artifacts, no floating fuzz or "cotton-like" noise. That's actually one of the major challenges in Gaussian Splatting.
I used an Insta360 Ace Pro 2 action camera, so the overall cost was kept pretty reasonable.
