Free TouchDesigner Project: OpenCV Camera & Projector Calibration (harveymoon)

Overview

GitHub user harveymoon shares a TouchDesigner add-on that calibrates a camera and projector pair using OpenCV, ported from ofxCvCameraProjectorCalibration. CameraProjectorCalibration.toe guides three steps: camera calibration from ChAruco board poses, projector calibration with a projected circle-dot grid, and a stereo calibration that links the two.

The README describes the physical setup, a printed ChAruco pattern taped to a white board with half left empty for projection, and links references on converting OpenCV to OpenGL projection matrices. The project is a free direct download from GitHub.
