Abstract

Procédé et dispositif de détermination d’obstacles d’altitude L’invention concerne un procédé et un dispositif de détermination d’obstacles d’altitude. Le procédé comporte, pour une zone géographique déterminée, l’obtention (50) d’images numériques aériennes de portions de terrain de ladite zone géographique à partir d’au moins une source d’images numériques aériennes, formant un ensemble d’images numériques aériennes couvrant ladite zone géographique. Le procédé comporte l’application (54) d’un premier traitement d’images aux images numériques dudit ensemble d’images pour obtenir un premier ensemble d’obstacles présents dans ladite zone géographique et une première estimation de hauteur associée, puis l’application (56) d’un deuxième traitement d’images aux images dudit ensemble d’images numériques pour obtenir un deuxième ensemble d’obstacles présents dans ladite zone géographique et une deuxième estimation de hauteur associée, supérieure ou égale à ladite hauteur minimale prédéterminée. En fonction des première et deuxième estimations de hauteur, un ensemble consolidé d’obstacles d’altitude, de hauteur supérieure ou égale à ladite hauteur minimale prédéterminée, présents dans ladite zone géographique, est obtenu (66, 68) et des attributs desdits obstacles d’altitude sont mémorisés (70).
