    摘要: The present application discloses a three-dimensional scanner and a three-dimensional scanning method. The three-dimensional scanner includes: an image projection device, configured to project light onto a target object, wherein the light includes predetermined light projected in the form of a color-coded stripe that is formed by coding stripes of at least two colors; and an image acquisition device, configured to acquire light modulated by the target object so as to obtain at least one stripe image in the case where light is projected onto the target object by the image projection device, wherein the obtained stripe image is taken as a coding image to determine respective stripe sequences and as a reconstruction image to perform three-dimensional reconstruction on the target object.
