Claim:
1. A desktop three-dimensional scanner for dental use, comprising: a camera; a projector; a mounting base on which the camera and the projector are mounted; a stage; a control operator; a first axis motion driver driving the mounting base to rotate about a horizontal rotation axis; and a second axis motion driver driving the stage to rotate about a vertical rotation axis, wherein the mounting base is installed to be rotatable around the horizontal rotation axis which is parallel to an upper surface of the stage, wherein the first axis motion driver is independently provided from the second axis motion driver, thereby the rotation about the vertical rotation axis of the stage capable of being simultaneously performed with the rotation about the horizontal rotation axis of the mounting base, and wherein the control operator is configured to control the camera, the projector, the first axis motion driver and the second axis motion driver to rotate the mounting base while irradiating scanning pattern light onto a target object to be scanned which is provided on the stage, through the projector and to implement a three-dimensional digital model of the target object.
