Abstract: The 3D information generating device includes a light source unit configured to irradiate light onto a target object, a coordinate mechanism unit disposed between the target object and the light source unit and including a plurality of inclined projections reflecting the light, a camera unit configured to output an image obtained by simultaneously photographing the coordinate mechanism unit and the target object, and an information processing unit configured to check a projection plane formed by the light of the light source unit and, by using the projection plane, generate 3D information about the target object while calibrating an error. Accordingly, an unskilled user may easily perform a 3D scan operation by using the coordinate mechanism unit, and moreover, since a coordinate mechanism is not installed in the outside, the 3D information generating device may easily move and may be easily maintained and managed.
