§ 01 — Brief
A DIY light-stage / multi-camera array — big labs have Debevec’s light stage; VFX houses have Microsoft Mixed Reality Capture. We used dozens of Raspberry Pi Camera V2 modules, a laser-cut wood frame, and RGB LED fill in an ordinary room: one button, dozens of angles of one head at once.
§ 02 — System
- Camera nodes: Raspberry Pi Camera Module V2 (8MP, fixed focus), each on a Pi Zero or 3B+
- Sync trigger: master Pi broadcasts a network trigger; all nodes expose within tens of milliseconds
- Lighting: RGB LED strips inside the camera rings — even illumination and visual drama (boot cycles mix violet / cyan / green)
- Frame: laser-cut thin plywood + acrylic hoops as a hemispheric scaffold, mounting holes cut per ring
- Post: all stills into photogrammetry (Meshroom / RealityCapture) → textured 3D face mesh
§ 03 — Role
Hardware side — camera tuning, Pi control, image transfer, network design.
§ 04 — Outcome
As installation art, the interesting part is not the mesh — it is being surrounded by cameras. Sit down, RGB flash, dozens of lenses look at you at once. That bodily sense of capture sticks longer than the final model.
