Abstract

A three dimensional image measurement system including a first optical system and a second optical system is provided. The first optical system is adapted to output a structural light beam and a zero order light beam. There is an angle between the structural light beam and the zero order light beam. The first optical system performs an optical operation to project the structural light beam to a three dimensional object to obtain three dimensional information of the three dimensional object. The second optical system is adapted to receive the zero order light beam and perform another optical operation by using the zero order light beam. The first optical system includes a plurality of optical elements. The value of the angle between the structural light beam and the zero order light beam is determined according to position parameters of the optical elements.
