Title (EN) DETECTING CODED LIGHT WITH ROLLING-SHUTTER CAMERAS
(FR) DÉTECTION DE LUMIÈRE CODÉE À L'AIDE DE CAMÉRAS À OBTURATEUR DÉROULANT
Abstract:
(EN) A method, program and apparatus for detecting a repeating coded light message embedded in light emitted by a light source, based on images captured from rolling- shutter cameras which capture their frame areas line-but-line. Images of the light source are captured simultaneously using a plurality of different rolling-shutter cameras having different acquisition regimes in order to improve the robustness and/or speed of coded light detection. The different acquisition regimes may comprise different frame rates, different physical orientations, or different line-readout directions.
(FR) L'invention concerne un procédé, un programme et un appareil pour détecter un message lumineux codé répétitif intégré à la lumière émise par une source de lumière, sur la base d'images capturées à partir de caméras à obturateur déroulant qui capturent leurs trames ligne par ligne. Des images de la source de lumière sont capturées simultanément à l'aide d'une pluralité de différentes caméras à obturateur roulant ayant différents régimes d'acquisition afin d'améliorer la robustesse et/ou la vitesse de la détection de la lumière codée. Les différents régimes d'acquisition peuvent comprendre différents débits de trames, différentes orientations physiques, ou différentes directions de lecture de lignes.
