Method for calibrating a projector with a camera

摘要

A method calibrates a projector with a camera being a fixed physical relationship relative to each other. An output image is projected onto a display surface for a first and second pose of the projector and the camera relative to a display surface. For each pose, an input image is acquired. For each pose, a projector perspective projection matrix and a camera perspective projection matrix is determined from each input image. For each pose, a transformation from the projector perspective projection matrix and the camera perspective projection matrix to Euclidean form is determined, and the projector intrinsic parameters from the transformations.
