Abstract
A system and method are disclosed for calibrating a plurality of projectors for three-dimensional scene reconstruction. The system includes a plurality of projectors and at least one camera, a camera-projector calibration module and a projector-projector calibration module. The camera-projector calibration module is configured to calibrate a first projector with the camera and generate a first camera-projector calibration data using camera-projector duality. The camera-projector calibration module is also configured to calibrate a second projector with the camera and generate a second camera-projector calibration data. The projector-projector calibration module is configured to calibrate the first and the second projector using the first and the second camera-projector calibration data.
