PROBLEM TO BE SOLVED: To provide a method for identifying an object by shape measurement.SOLUTION: A method for identifying an object comprises: a step for acquiring an identification feature for shape measurement of the object; and a step for comparing an identification feature of the object representing the acquired identification feature with an identification feature in a database. The object is identified by the shape measurement. The identification feature for the shape measurement of the object is obtained by sighting on the object a pulsed laser beam having a pulse of length Li. The length Li is at least 10 times shorter than length Ru, of the object involved along a sighting axis of the laser. |
