Abstract

Un procedimiento de calibrar un heliostato de un campo de heliostatos, comprendiendo el procedimiento proporcionar una transformación lineal para convertir coordenadas tridimensionales a coordenadas bidimensionales en píxeles en una imagen; obtener las coordenadas tridimensionales reales de los puntos de las esquinas de la superficie reflectante de cada heliostato; para una imagen capturada por un primer dispositivo de toma de imágenes y una imagen capturada por un segundo dispositivo de toma de imágenes en un momento determinado: obtener las coordenadas bidimensionales de los puntos de las esquinas de la superficie reflectante; identificar el contorno de la superficie reflectante de cada heliostato en cada imagen; identificar una ROI en cada imagen. Para cada heliostato seleccionado, obtener un primer parámetro de la intensidad de los píxeles de la ROI correspondiente al heliostato en la imagen capturada por el primer dispositivo; obtener un segundo parámetro relacionado con la intensidad de los píxeles de la ROI correspondiente al heliostato en la imagen capturada por el segundo dispositivo; determinar unos ajustes a aplicar al heliostato; aplicar los ajustes.
