Description

The invention relates to a method for the remote inspection of a structure, comprising the following operations: producing a 3D image of an area of the structure to be inspected; superimposing said 3D image with a previously stored digital model of the structure; geographically locating the area of the structure to be inspected on the structure model; and inspecting the area of the structure to be inspected on the 3D image superimposed with the digital model. The invention also relates to a system for implementing the method, comprising an imaging device (10) that can be installed in the vicinity of the area of the structure to be inspected (2), and an image-processing device (6) located remotely from the imaging device (10) in order to generate a 3D image from the images captured by the camera (11), and a computer (4, 5) remote from the structure and capable of superimposing the 3D image with the digital model of the area of the structure.

L'invention concerne un procédé d'inspection à distance d'une structure, comportant les opérations suivantes : réalisation d'une image 3D d'une zone de la structure à inspecter,- superposition de cette image 3D avec une maquette numérique de la structure préalablement mémorisée; localisation géographique, sur la maquette de la structure, de la zone de la structure à inspecter; et inspection, sur la superposition de l'image 3D et de la maquette numérique, de la zone de structure à inspecter. Elle concerne aussi un système de mise en uvre du procédé comportant un dispositif de prise d'images (10) apte à être installé à proximité de la zone de structure à inspecter (2) et un dispositif de traitement d'images (6) placé à distance du dispositif de prise d'images (10) pour générer une image 3D à partir d'images réalisées par la caméra (11), et un ordinateur (4,5) éloigné de la structure apte à superposer l'image 3D avec une maquette numérique de la zone de la structure.
