<P>PROBLEM TO BE SOLVED: To provide a three-dimensional measurement system and a three-dimensional measurement method by stereo photographing which facilitates external orientation. <P>SOLUTION: The three-dimensional measurement system comprises: a stereo photographing unit 11 photographing a measurement object 1 from a plurality of directions and obtaining a stereo image 20; a sub reference body 3 constituting a part of a reference body 2, which covers a whole measurement object 1, and having a plurality of reference marks 4; a reference body information defining unit 12 defining, as an integrated body in a three-dimensional calculation space V, a reference body model 102, which is a three- dimensional numerical analysis model of the reference body, including photographing measured values f of three-dimensional coordinate values of the plurality of reference marks provided on the sub reference body based on the stereo image photographed by the stereo photographing unit and reference measured values g measured in advance; an orientation element calculation unit 13, which calculates external orientation elements of the stereo photographing unit using the reference body model; and a three-dimensional measurement unit 14, which operates three-dimensional measurement of the measurement object based on the stereo image of the measurement object photographed by the stereo photographing unit localized by the external orientation elements. <P>COPYRIGHT: (C)2013,JPO&INPIT |
