h1. Multi‑Projector Blending System p=. _Team G11 · Python / OpenCV · Semester 2025_ h2. Project Overview *Problem:* Two projectors produce overlapping images overlap on a planar screen, creating luminance non‑uniformity (the flat screen. Without blending, the shared region appears brighter). brighter than its surroundings. *Approach:* Detect the overlap and apply spatially smooth alpha‑blending masks whose weights vary linearly from 1 to 0 with a linear 1→0 falloff across the overlap band. *Deliverable:* A minimal, reproducible still‑image prototype implemented in Python (OpenCV). --- h2. Objectives * Define Describe the problem and select outline a feasible solution path prior to implementation. before coding. * Implement an a basic alpha‑blending pipeline and pipeline; iterate until seams are not perceptible visible at normal viewing distance. * Validate the method Demonstrate results with a small set of test images, recording inputs, images and concise notes (inputs, parameters, and outcomes to ensure reproducibility. outcome). *Success criterion:* no visible seam or luminance discontinuity in the overlap region. --- h2. Scope & Operating Assumptions * *Configuration:* two projectors and a Two projectors; flat, planar screen; projector optical axes nominally normal (perpendicular) approximately perpendicular to the screen. * *Media:* still Still images for the initial phase first (video may follow). considered later). * *Overlap geometry:* approximately The overlap is roughly rectangular; blend weights vary drop linearly from 1 to 0 1→0 across the overlap. * *Calibration philosophy:* favor simple, reproducible steps; apply additional calibration Keep methods simple and reproducible; refine only if visible artifacts persist. remain. --- h2.
