Abstract: The invention relates to a motorized flying craft (10) for measuring the contour of a plurality of regions of interest (12a, 12b, 12c) of a surface of a predetermined object (9) to be inspected, said flying craft (10) comprising a carrier frame (20) and motorized means (11, 13) for lifting and moving said carrier frame (20). The flying craft is characterized in that it further comprises an apparatus (14) for three-dimensional measurement of a region of interest (12a, 12b, 12c) targeted by said apparatus (14), and a management system (34, 35) of said craft configured to be able to switch said craft from a navigation mode, in which the craft can be moved from one region of interest to a subsequent region of interest, to a stabilized mode, in which said motorized lifting and movement means (11, 13) are controlled so as to be able to keep at least one kinematic parameter of said craft constant, making it possible to minimize the vibration of said craft, and in which said measurement apparatus (14) can acquire a three-dimensional measurement of a region of interest.

Abstract: The invention relates to a method for determining the relative position of a moving object in relation to an environment modelled by a set of geometric surfaces that form a 3D model in accordance with a frame of reference in the environment, comprising a step (10) of measuring a plurality of distances from the object to the environment in at least one direction, so as to obtain a set of defined points in a frame of reference of the moving object, a step of evaluating a difference between said set of points and the 3D mesh of the environment, and a step (20) of determining the relative position of the moving object in the frame of reference of the environment from said difference.
