Claim 0:
1. A motorized flying craft for measuring the contour of a plurality of regions of interest of a surface of a predetermined object to be inspected, said flying craft comprising:
a carrier frame,
motorized means for lifting and moving said carrier frame,
an apparatus for three-dimensional measurement of a region of interest targeted by said apparatus, which apparatus is mounted on a pod which is mechanically connected to said carrier frame, said apparatus comprising a reference wave emission source, a matrix receiver of a wave reflected by said region of interest targeted by said apparatus, and a processing unit configured to be able to determine a measurement of the contour of said region of targeted by said apparatus from the analysis of said reference wave and said reflected wave,
an automatic management system of said craft, which system is configured to be able to switch said craft from a navigation mode in which the craft can be moved from one region of interest toward a subsequent region of interest by controlling motorized lifting and movement means, to a stabilized mode in which said motorized lifting movement means are controlled so as to be able to keep at least one kinematic parameter of said craft constant, selected from the group comprising the speed of the craft, the acceleration of the craft, the attitude of the craft, and a function of one or more of these parameters, making it possible to minimize the vibration of said craft, and in which said measurement apparatus can acquire a three-dimensional measurement of a region of interest;
said automatic management system being configured to be able, in the vicinity of each region of interest, to switch from the navigation mode to the stabilized mode when said craft is in a state which is defined by said kinematic parameter of the craft and adjacent to an anticipation state, which is defined by at least this kinematic parameter of the craft, and determined from an acquisition state which corresponds to a target value of this kinematic parameter for carrying out the acquisition of this region of interest, and to an anticipation time delay which corresponds to the time necessary to guarantee that this parameter is kept constant by the craft, allowing the acquisition of a three-dimensional measurement of said region of interest by said measurement apparatus.
