SYSTEM AND METHOD FOR ONLINE PROJECTOR-CAMERA CALIBRATION FROM ONE OR MORE IMAGES

摘要

A system and method for online projector-camera calibration from one or more images is provided. The system (200) comprises: a projector (207), a camera (214), and a calibration device (201) configured to: determine a map (560) between pixels of each of a projector image (440) and a camera image (450) in fewer than one hundred percent of pixels of the projector image (440) using feature extraction; determine an initial estimate of a fundamental matrix from the map (560); determine an initial guess of intrinsic properties of the projector (207) and camera (214) using one or more closed-form solutions; iteratively determine an error-function based on the map (560) using the fundamental matrix while adding constraints on the intrinsic properties using the one or more closed-form solutions, and the initial estimate and guess as initial input; and, when the error-function reaches an acceptance value, determine intrinsic and extrinsic properties of the projector (207) and the camera (214) from current values of iterative estimates.
