PROJECTOR CALIBRATION SYSTEM USING CAMERA AND METHOD USING THIS

摘要

PURPOSE: A projector correcting system using a camera and a correcting method using the same are provided to actually apply to a structured-light system using a camera with a known inner parameter. CONSTITUTION: A projector correcting system using a camera comprises a projector, a camera(200) and a calculating/processing unit. The camera obtains images projected from the projector. The camera knows an inner parameter. The calculating/processing unit obtains the pattern and corresponding point of an image projected from the projector from the image obtained from the camera. The calculating/processing unit applies epipolar geometry to the obtained corresponding point. The calculating/processing unit obtains the inner parameter of the projector.
