Abstract

A three-dimensional measurement system includes a measurement platform, a projection module, an image-capturing module, and a control unit. The measurement platform carries a test object. The projection module includes a light-emitting unit, a light-shielding rotary disc, a grating unit, and an optical-reflective ring structure. The light-emitting unit generates a light beam. An aperture formed in the light-shielding rotary disc is located at different rotational positions time-sequentially while the light-shielding rotary disc rotates, and the light beam passes through the aperture to form light beam segments. The grating unit transforms the light beam segments into stripe-patterned structure-light beams. The optical-reflective ring structure reflects the stripe-patterned structure-light beams onto the test object. The image-capturing module captures stripe-patterned images formed after reflection of the stripe-patterned structure-light beams from the test object. The control unit measures a three-dimensional shape of the test object using the stripe-patterned images.
