Abstract: 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.

Abstract: A three-dimensional modeling method according to the present invention includes: a scan step of scanning a subject to be filtered so as to obtain at least one set of image data; a step of determining a reference color or a reference color range from a color included in the image data obtained in the scan step and filtering the reference color or the reference color range; and a step of generating a three-dimensional surface model of a subject to be modeled by scanning the subject to be modeled, wherein the step of generating the three-dimensional surface model includes excluding the reference color or the reference color range to generate the three-dimensional surface model.

Abstract: The present disclosure relates to an apparatus and method for generating a virtual model. The apparatus according to the present disclosure comprises: a scanner that acquires a continuous 2D image within a measurement space; and a model generation unit for generating a three-dimensional virtual model by converting the image acquired from the scanner, wherein the model generation unit removes an area from the three-dimensional virtual model according to the reliability of data and generates a final model on the basis of the remaining area.

Abstract: A method for controlling a three-dimensional scanning system includes a scanning step of scanning a target by using a three-dimensional scanner and acquiring a distance between the three-dimensional scanner and the target, and a switching step of switching an activation state of at least one feedback means on the basis of the distance.

Abstract: According to the present disclosure, partial precision shape data is added to overall data by combining scan data obtained by a first scanner and a second scanner, respectively, and thus, missing data in a scan of the first scanner is supplemented by a scan of the second scanner. There is an advantage of being able to derive highly reliable data through such a supplementary process, and a user can provide a more suitable treatment to the patient.

Abstract: According to a combined intraoral and impression scanning system and method of the present invention, intraoral scan data of an intraoral object can be obtained and stored, and impression scan data of the oral object can be selectively stored from an intraoral scan data area that satisfies a preset determination condition. By applying the intraoral scan data area corresponding to the preset determination condition as the impression scan data, highly reliable final scan data can be obtained and a precise prosthesis can be manufactured.
