Abstract: PURPOSE: A non-contact 3-D(3 Dimensional) scanner is provided to create 3-D shape of an object to be measured by sequent projecting stripe pattern onto the object and simultaneously photographing the shape of the object several times. CONSTITUTION: An LCD(Liquid Crystal Display) projector(10) sequentially projects a series of stripe patterns onto an object to be measured. A CCD(Charge Coupled Device) set(13) comprises the first and the second CCD camera(11,12) physically connected each other by signal input and output line for synchronization of photographing and lactationally calibrated for obtaining basic coordinates. The first and The second CCD camera(11,12) simultaneously photographs the object projected by the LCD projector(10) once per one stripe pattern and transmits image data of the object. A control computer(14) connected to the LCD projector(10) and CCD set(13) controls the LCD projector(10) and the CCD cameras(11,12) to project the patterns and photograph the object. The control computer(14) receives the image data of the object from the CCD cameras(11, 12) and creates 3-D shape of the object.
