Multi‑Projector Blending System¶

Team G11 · Python / OpenCV · Semester 2025

Project Overview¶

• Display one seamless still image on a flat screen using two projectors with an overlapped area.
• Equalize brightness in the overlap with alpha‑blending so seams disappear.
• Prototype in Python (OpenCV); refine only as needed.

Objectives¶

1. Describe the problem and a feasible solution path before coding.
2. Build a minimal alpha‑blending prototype and iterate until seams vanish.
3. Provide before/after evidence on multiple test images.
4. Keep the workflow and calibration reproducible.

Scope & Assumptions¶

• Planar screen; two projectors; optical axes ≈ perpendicular to the screen.
• Still images first (video later if time permits).
• Overlap is roughly rectangular; mask intensity falls linearly from 1→0 across the band.
• Minimal calibration; fine‑tune only if artifacts are visible.
