Abstract:
A three-dimensional shape-measuring system, which directs laser light to a measuring subject placed in a measuring space from a plurality of directions by using a light projector so that a light receiver detects reflected light derived from said laser light from said light projector reflected by said measuring subject to generate a three-dimensional shape data of said measuring subject, comprising:a controller which, prior to measurements on said measuring subject, controls said light projector and said light receiver so as to measure a calibration-use subject placed in said measuring space from said plurality of directions; a data processor which finds a conversion parameter used for converting measured data related to said calibration-use subject, obtained respectively in said plurality of directions, to three-dimensional shape data in a world coordinate system; and a memory storing said conversion parameter; wherein said three-dimensional shape data is generated by data-converting said measured data related to said calibration-use subject, obtained respectively in said plurality of directions, by the use of said conversion parameter.
