Abstract
Un procédé d’étalonnage d’un héliostat d’un champ d’héliostats comprend un procédé visant à fournir une transformation linéaire pour convertir des coordonnées tridimensionnelles en coordonnées bidimensionnelles dans des pixels d’une image ; obtenir les coordonnées tridimensionnelles réelles des points des coins de la surface réfléchissante de chaque héliostat ; pour une image capturée par un premier dispositif de prise d’images et une image capturée par un second dispositif de prise d’images à un moment déterminé, obtenir les coordonnées bidimensionnelles des points des coins de la surface réfléchissante ; identifier le contour de la surface réfléchissante de chaque héliostat dans chaque image ; identifier une région d’intérêt dans chaque image. Pour chaque héliostat choisi, ledit procédé consiste à obtenir un premier paramètre de l’intensité des pixels de la région d’intérêt correspondant à l’héliostat dans l’image capturée par le premier dispositif ; obtenir un second paramètre relatif à l’intensité des pixels de la région d’intérêt correspondant à l’héliostat dans l’image capturée par le second dispositif ; déterminer des réglages à appliquer à l’héliostat ; appliquer lesdits réglages.A method of calibrating a heliostat of a heliostatic field comprises a method for providing a linear transformation for converting three-dimensional coordinates into two-dimensional coordinates in pixels of an image; obtain the real three-dimensional coordinates of the points of the corners of the reflective surface of each heliostat; for an image captured by a first image pickup device and an image captured by a second image pickup device at a determined time, obtaining the two-dimensional coordinates of the points of the corners of the reflective surface; identify the contour of the reflective surface of each heliostat in each image; identify a region of interest in each image. For each heliostat chosen, said method consists in obtaining a first parameter of the intensity of the pixels of the region of interest corresponding to the heliostat in the image captured by the first device; obtaining a second parameter relating to the intensity of the pixels of the region of interest corresponding to the heliostat in the image captured by the second device; determine settings to apply to the heliostat; apply these settings.
