Title (EN) A METHOD OF IDENTIFYING LIGHT SOURCES, CORRESPONDING SYSTEM AND COMPUTER PROGRAM PRODUCT
(FR) PROCÉDÉ D'IDENTIFICATION DE SOURCES DE LUMIÈRE, SYSTÈME CORRESPONDANT ET PRODUIT PROGRAMME INFORMATIQUE
Abstract:
(EN) A "smart" lighting system including a set of lighting devices (SI, S6) for lighting an environment is controlled by: - receiving (100) from one or more image sensors (e.g. a RGB-D camera - W) an image signal including a sequence of images of the environment under different conditions of illumination and light reflection, - processing (102 to 120) the image signal to provide a light source identification signal (120) representative of light sources affecting the environment, and - controlling the lighting devices (SI, S6) as a function of the light source identification signal (120), and, possibly, of human occupancy and activity.
(FR) Selon l'invention, un système d'éclairage « intelligent » comprenant un ensemble de dispositifs d'éclairage (S1, S6) permettant d'éclairer un environnement est commandé selon les étapes suivantes : - recevoir (100) à partir d'un ou de plusieurs capteurs d'image (par exemple une caméra RVB-D (W)) un signal d'image contenant une séquence d'images de l'environnement dans différentes conditions d'éclairage et de réflexion de lumière, - traiter (102 à 120) le signal d'image pour fournir un signal d'identification de source de lumière (120) représentatif de sources de lumière influençant l'environnement, et - commander les dispositifs d'éclairage (S1, S6) en fonction du signal d'identification de source de lumière (120) et, éventuellement, de l'occupation et de l'activité humaines.
