Title (EN) MULTICHROMATIC CALIBRATION METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF D'ÉTALONNAGE POLYCHROMATIQUE
Abstract:
(EN) A Multichromatic Calibration (MC) method of at least a spectral sensor which is one of a list comprising at least a spectrometer, a multispectral sensor, a hyperspectral sensor, a spectral camera, a color camera. The method comprises a. generating a plurality of different multichromatic spectra, wherein i. a spectrum from the plurality of different multichromatic spectra contains light intensity measurable by the at least one spectral sensor and by a reference spectral device, and ii. a spectrum from the plurality of different multichromatic spectra contains light centered around at least two different wavelengths and is configured to be integrated during an exposure time of a single measurement from any of the at least one spectral sensor or the reference spectral device; b. measuring each multichromatic spectrum of the plurality of different multichromatic spectra with the reference spectral device and the at least one spectral sensor; and from all data of the measured multichromatic spectra, compute a transfer function which relates a response of the at least one spectral sensor to a corresponding response of the reference spectral device, without measuring the spectral response of the at least one spectral sensor.
(FR) Cette invention concerne un procédé d'étalonnage polychromatique (MC) d'au moins un capteur spectral qui est l'un d'un ensemble comprenant au moins un spectromètre, un capteur multispectral, un capteur hyperspectral, une caméra spectrale et une caméra couleur. Le procédé comprend les étapes consistant à : (a) générer une pluralité de spectres polychromatiques différents, où (i) un spectre de la pluralité de spectres polychromatiques différents contient une intensité lumineuse mesurable par le(s) capteur(s) spectral/spectraux et par un dispositif spectral de référence, et (ii) un spectre de la pluralité de spectres polychromatiques différents contient une lumière centrée autour d'au moins deux longueurs d'onde différentes et est configuré pour être intégré pendant un temps d'exposition d'une seule mesure de l'un quelconque du/des capteur(s) spectral/spectraux ou du dispositif spectral de référence ; (b) mesurer chaque spectre polychromatique de la pluralité de spectres polychromatiques différents avec le dispositif spectral de référence et le(s) capteur(s) spectral/spectraux ; et à partir de toutes les données des spectres polychromatiques mesurés, calculer une fonction de transfert qui concerne une réponse du/des capteur(s) spectral/spectraux à une réponse correspondante du dispositif spectral de référence, sans mesurer la réponse spectrale du/des capteur(s) spectral/spectraux.
