Title:
THREE-DIMENSIONAL SCANNER AND THREE-DIMENSIONAL SCANNING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/078300
Kind Code:
A1
Abstract:
A three-dimensional scanner (71) and a three-dimensional scanning method. The three-dimensional scanner (71) comprises: an image projection device (10) used for projecting light onto a target object, wherein the light comprises preset light projected in the form of color coded stripes, the color coded stripes being formed by coding stripes of at least two colors; and an image acquisition device (20) used for collecting, when light is projected to the target object by the image projection device (10), light modulated by the target object to obtain at least one stripe image, wherein the obtained stripe mage is used as a coded image to determine each stripe sequence, and as a reconstructed image to perform three-dimensional reconstruction of the target object. According to the three-dimensional scanner and the three-dimensional scanning method, the technical problem of being not conducive to the popularization of a three-dimensional scanning device caused by high hardware costs required by the existing three-dimensional reconstruction method is solved.
