This invention relates to an apparatus and a method for rapid and precise scanning of the three-dimensional (3-D) profile of a dental cast. Disclosed is a measurement apparatus comprising two symmetrically arranged optical projection units and plural image capturing units each including optical components and optical lenses. The geometrical relationship between the optical projection units and the plaster dental cast are such arranged to ensure precise projection of laser beams and comprehensive measurement. The plural image capturing units serve to capture the reflected, structured light patterns, based on which patterns a 3-D occlusal profile is rapidly and precisely calculated through the triangulation principle, thereby allowing efficient and precise measurement of the 3-D occlusal profile of the plaster dental cast.
