Abstract

L'invention concerne un procédé et un système de protection solaire intelligente pour un pare-soleil d'automobile, un terminal et un support de stockage. Le procédé de protection solaire comprend les étapes suivantes : acquisition respective de données de position du soleil, d'un espace de zone oculaire humaine et de données d'angle de rotation d'un pare-soleil ; obtention de données de zone de protection solaire du pare-soleil au moyen des données de position du soleil, de l'espace de zone oculaire humaine et des données d'angle de rotation du pare-soleil ; et réalisation d'une opération de protection solaire au moyen des données de zone de protection solaire du pare-soleil. Une caractéristique de transmission de lumière est présentée dans un état de non-fonctionnement. Les positions des yeux humains et un angle d'incidence de la lumière solaire sont reconnus dans un état de fonctionnement, en combinaison avec un algorithme spécifique, les coordonnées de position spatiale pour la protection contre la lumière solaire sur un trajet de lumière solaire incidente sur les yeux humains sont obtenues, et le facteur de transmission de lumière de la zone correspondante sur le pare-soleil est réduit, de sorte qu'un effet de protection local est présenté et un champ de vision pour la conduite est maximisé.
