    摘要： The present invention relates to a three-dimensional oral scanner. In particular, the present invention comprises: a case which can be drawn in and out of an oral cavity and has an opening formed in a manner such that the shape of the inside of the oral cavity (hereinafter, abbreviated as “image”) is introduced to the inside in the form of light through one end thereof; a pair of lenses disposed inside the case and spaced apart from each other in the width direction of the case so as to pass light incident from one end of the case in different paths; a pair of imaging boards having an imaging sensor for imaging the respective lights transmitted through the pair of lenses and disposed in close contact with a widthwise side wall and the other widthwise side wall of the case; and a pair of light path changing units arranged to change the respective paths of the lights transmitted through the pair of lenses toward the imaging board. As such, it is possible to manufacture an oral scanner to be slim overall, while providing the advantage of maximizing the utilization of the internal space of the oral scanner.

    摘要： An image processing method may include steps of obtaining a plurality of image data from an object, generating, from the image data, a three-dimensional (3-D) model having at least two different representation modes, and displaying the generated 3-D model. There is an advantage in that a user can check various information of a 3-D model without changing a representation mode by displaying a 3-D model having at least two different representation modes.

    摘要： The present disclosure discloses a three-dimensional data alignment apparatus, a three-dimensional data alignment method, and a recording medium, which may align a location between volumetric data and surface data even without a segmentation process of extracting a surface from the volumetric data. A three-dimensional data alignment apparatus according to an exemplary embodiment of the present disclosure includes a three-dimensional data alignment unit for aligning a location between first three-dimensional data and second three-dimensional data expressed in different data forms with regard to a target to be measured. The first three-dimensional data are three-dimensional data acquired in a voxel form with regard to the target to be measured, and the second three-dimensional data are three-dimensional data acquired in a surface form with regard to the target to be measured. The three-dimensional data alignment unit is configured to extract one or more vertices from the second three-dimensional data; extract the first voxel values of first voxels located around each vertex from the first three-dimensional data, based on a location of each vertex extracted from the second three-dimensional data; determine corresponding points between the first three-dimensional data and the second three-dimensional data based on the first voxel values extracted from the first three-dimensional data; and calculate location conversion information minimizing a location error between the first three-dimensional data and the second three-dimensional data based on the corresponding points.
