Abstract: A disclosure of the present invention is related to an apparatus and a method for generating three-dimensional information. The apparatus for generating three-dimensional information may include a light source providing light to an object to be reconstructed in three-dimensional information, a coordinate reference mechanism unit provided between the light source and the object and having a plurality of protrusions reflecting the light; a camera unit outputting an image capturing the coordinate reference mechanism unit and the object simultaneously; and a three-dimensional information processing unit generating the three-dimensional information of the object by identifying a projection plane formed by the light and using the projection plane, considering a relationship between a plurality of actual protrusion reflection points at which the light is reflected by the plurality of protrusions respectively and a plurality of protrusion reflection points displayed in the image.

Abstract: Provided is a method of reconstructing a three-dimensional (3D) model of an object. The method includes sequentially performing, by a camera module, first and second object scanning processes of scanning the same object, reconstructing, by a processor module, a 3D object model, based on a first object image obtained through the first object scanning process, performing pose learning on an object to generate learning data, based on data obtained through a process of reconstructing the 3D object model based on the first object image, and reconstructing, by the processor module, a final 3D object model, based on a second object image obtained through the second object scanning process and the learning data.

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.
