CA 2658513

Digital Surface Model (DSM) texturing and modeling of various objects on the earth's surface are provided for implementation in a mapping application. One or more image capture devices having wide-angle lenses can be placed in various configurations to obtain nadir and oblique photography. Such configurations include a single lens, single sensor; single lens, multiple sensor; multiple lens, multiple sensor; and multiple lens, multiple sensor and a reflective surface. Positions, distances and areas can be measured from the imagery. Also provided is a continuous morph between aerial panorama and ground images.

L'invention concerne la texturation et la modélisation de modèle de surface numérique (DSM) de divers objets à la surface de la Terre étant mis en AEuvre dans une application de cartographie. Un ou plusieurs dispositifs de prise d'image ayant des lentilles à grande ouverture peuvent être placés dans diverses configurations pour obtenir une photographie nadir et oblique. De telles configurations peuvent comprendre une lentille unique, un déclencheur unique ; une lentille unique, plusieurs déclencheurs ; et plusieurs lentilles, plusieurs déclencheurs et une surface réfléchissante. Des positions, des distances et des régions peuvent être mesurées à partir de l'imagerie. Il est également proposé un morphe continu entre un panorama aérien et des images au sol.
