Multi‑Projector Blending System — Start Page¶

Team G11 · Python / OpenCV · Semester 2025

Project Overview¶

Problem: Two projectors overlap on a flat screen. Without blending, the shared region appears brighter than its surroundings.
Approach: Detect the overlap and apply smooth alpha‑blending masks with a linear 1→0 falloff across the band.
Deliverable: A minimal, reproducible still‑image prototype implemented in Python (OpenCV).

Objectives¶

• Describe the problem and outline a feasible solution before coding.
• Implement a basic alpha‑blending pipeline; iterate until seams are not visible at normal viewing distance.
• Demonstrate results with a small set of test images and concise notes (inputs, parameters, outcome).

Scope & Operating Assumptions¶

• Two projectors; flat, planar screen; projector optical axes approximately perpendicular to the screen.
• Still images first (video considered later).
• The overlap is roughly rectangular; blend weights drop linearly from 1→0 across the overlap.
• Keep methods simple and reproducible; refine only if artifacts remain.
