Document Type and Number:
WIPO Patent Application WO/2020/103822
Kind Code:
A1
Abstract:
A projecting device, an acquisition device, and a three-dimensional scanning system having same. The projecting device comprises: a light emitting part (11), configured to emit a plurality of preset light rays, wherein the plurality of preset light rays corresponds to a plurality of preset wave bands, and the plurality of preset wave bands is different from each other; and a light transmission part (13), disposed on the transmission path of the preset light rays, wherein after the preset light rays are transmitted by a preset pattern disposed on the light transmission part (13), target light rays projecting on a target object in the form of color encoded stripes are generated and the light transmission part (13) transmits preset light rays corresponding to at least two different preset wave bands. The problems that a method for acquiring the three-dimensional shape of an object in the related art is not suitable for the oral cavity environment and the costs of the method for acquiring the three-dimensional shape of an object in the related art are high are solved.
