Abstract
The present application discloses a projection apparatus, a collection apparatus, and a three-dimensional scanning system with the same. The projection apparatus includes: a light emission portion, configured to emit multiple rays of preset light, wherein the multiple rays of preset light correspond to multiple preset wavebands, and the multiple preset wavebands are different from each other; and a light transmission portion, disposed on a transmission path of the rays of preset light, wherein the rays of preset light is transmitted via a preset pattern on the light transmission portion to generate target light projected to a target object in the form of color-coded fringes, and the light transmission portion transmits the rays of preset light corresponding to at least two different preset wavebands.
