Abstract: A multicamera imaging system includes multiple imaging subsystems. Each subsystem includes imaging optics, an optical filter, an optional shutter, a digital imaging sensor, and an analog-to-digital converter. After optional scaling, image displacement, keystone and other corrections, the captured images are aligned to result in a multi-layer registered image. Illumination metrics of individual pixels of the registered image are then calculated. The spatial distribution of the optical illumination properties of planar objects are measured, including colorimetric, photometric, radiometric, and spectroradiometric characterization and calibration of digital image displays and radiant scenes.
