An optical system includes an optical apparatus. The optical apparatus is for projecting a first projection image to a plane or detecting a first detected image of the plane. The optical apparatus includes a first image device, and a lens group. The first image device has an image surface having an image center. The lens group is disposed between the first image device and the plane and has a lens axis surface and an optic center. The optic center and the image center form a connection line. The plane has a tangent surface to an intersecting point of the connection line. The lens axis surface, the tangent surface, and an extension surface of the image surface substantially intersect at a straight line.

Optical system and image compensating method of optical apparatus

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.
