Splatcam: LiDAR Capture

SplatCam captures everything you need for 3D Gaussian Splatting training in a single session — images, camera poses, and a dense colored point cloud — using iPhone's LiDAR sensor. ***NOTE: You will then need to transfer this data to a PC for processing with splatting software like LichtFeld Studio, Postshot, etc. to get the final scene.***

Walk around any object or scene and SplatCam handles the rest. Each capture records the camera frame, full intrinsic and extrinsic parameters, and accumulates a spatially-deduplicated point cloud from the LiDAR depth buffer in real time. When you're done, export a ready-to-train .zip containing a transforms.json, point cloud PLY, and images — no COLMAP or SfM pipeline required. Just load the folder into LichtFeld Studio (free), Postshot (paid), or any other RealityScan-compatible system and you're good to go.

Features:
- Real-time dense point cloud accumulation from LiDAR depth with spatial deduplication
- Manual shutter mode with volume button trigger
- Continuous auto-capture mode with distance/angle thresholds and blur rejection
- Live camera-perspective and overhead point cloud preview during capture
- Tracking quality indicator with motion and feature warnings
- Loop closure guidance to improve reconstruction accuracy
- Exports LichtFeld Studio / Postshot compatible transforms.json with full camera intrinsics and extrinsics
- Binary PLY point cloud with per-vertex color
- One-tap .zip export to Dropbox, AirDrop, Files, etc for transport to PC for processing

Output is directly compatible with LichtFeld Studio, Postshot, and other tools that accept the standard transforms.json + images + point cloud format.

Requires iPhone 12 Pro or later (LiDAR-equipped device). Gaussian Splat generation generally requires a CUDA-capable PC.
