A method for reconstructing the geometry of a surface (S; LF) of an object (102; 102') via echographic probing using an ultrasound probe provided with a plurality of transducers (114 1,..., 114 N), comprising the following steps: - controlling (204 1,..., 204 N) the transducers (114 1,..., 114 N) such that they transmit towards said surface (S; LF) of the object ultrasound waves having initial transmission delays (L 0) in relation to one another, - executing at least once the following cycle of steps, in such a way as to obtain after at least one iteration a wavefront received simultaneously on the surface: • receiving (212 1,..., 212 N) from the transducers (114 1,..., 114 N) intermediate measurement signals, measuring in particular echoes due to reflections of the ultrasound waves on said surface (S; LF) of the object, • correcting the transmission delays of the transducers (114 1,..., 114 N) using the intermediate measurement signals and controlling (204 1,..., 204 N) the transducers (114 1,..., 114 N) such that they transmit towards said surface (S; LF) of the object ultrasound waves having the corrected transmission delays (L p) in relation to one another, - receiving (212 1,..., 212 N) from the transducers (114 1,..., 114 N) final measurement signals resulting from the reflection of a wavefront received simultaneously on said surface (S; LF) of the object, characterized in that it further comprises the following steps: - determining specular travel times, each corresponding to the minimum time taken by a signal transmitted by a transducer to return to this transducer in the form of an echo following a reflection against the surface of the object, between each transducer (114 1,..., 114 N) and said surface (S; LF) of the object on the basis of the final measurement signals and of the corrected transmission delays (L f), and - geometric reconstitution (228, 230, 232) of said surface (S; LF) of the object on the basis of the determined specular travel times. - controlling (204 1,..., 204 N) the transducers (114 1,..., 114 N) such that they transmit towards said surface (S; LF) of the object ultrasound waves having initial transmission delays (L 0) in relation to one another, - executing at least once the following cycle of steps, in such a way as to obtain after at least one iteration a wavefront received simultaneously on the surface: • receiving (212 1,..., 212 N) from the transducers (114 1,..., 114 N) intermediate measurement signals, measuring in particular echoes due to reflections of the ultrasound waves on said surface (S; LF) of the object, • correcting the transmission delays of the transducers (114 1,..., 114 N) using the intermediate measurement signals and controlling (204 1,..., 204 N) the transducers (114 1,..., 114 N) such that they transmit towards said surface (S; LF) of the object ultrasound waves having the corrected transmission delays (L p) in relation to one another, • receiving (212 1,..., 212 N) from the transducers (114 1,..., 114 N) intermediate measurement signals, measuring in particular echoes due to reflections of the ultrasound waves on said surface (S; LF) of the object, • correcting the transmission delays of the transducers (114 1,..., 114 N) using the intermediate measurement signals and controlling (204 1,..., 204 N) the transducers (114 1,..., 114 N) such that they transmit towards said surface (S; LF) of the object ultrasound waves having the corrected transmission delays (L p) in relation to one another, - receiving (212 1,..., 212 N) from the transducers (114 1,..., 114 N) final measurement signals resulting from the reflection of a wavefront received simultaneously on said surface (S; LF) of the object, - determining specular travel times, each corresponding to the minimum time taken by a signal transmitted by a transducer to return to this transducer in the form of an echo following a reflection against the surface of the object, between each transducer (114 1,..., 114 N) and said surface (S; LF) of the object on the basis of the final measurement signals and of the corrected transmission delays (L f), and - geometric reconstitution (228, 230, 232) of said surface (S; LF) of the object on the basis of the determined specular travel times.
