1. A three-dimensional scanner, comprising:
an image projection device (10), configured to project light onto a target object, wherein the light comprises predetermined light projected in a form of a color-coded stripe, the predetermined light is formed by coding stripes of at least two colors; and
an image acquisition device (20), configured to acquire light modulated by the target object so as to obtain at least one stripe image when light is projected onto the target object by the image projection device (10), 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;
wherein the image acquisition device (20) further comprises a plurality of cameras (21), the plurality of cameras (21) comprising at least one monochrome camera, wherein the image acquisition device (20) acquires the light modulated by the target object through the plurality of cameras (21) to obtain a plurality of stripe images, a stripe image obtained by the at least one monochrome camera is taken as a reconstruction image to perform three-dimensional reconstruction on the target object; and stripe images obtained by at least a plurality of monochrome cameras are taken as coding images to determine respective stripe sequences, and/or, a stripe image obtained by at least one color camera is taken as a coding image to determine respective stripe sequences.
