Abstract: An image filtering method according to the present disclosure comprises: acquiring a two-dimensional image through a scanner, and acquiring color information of at least part of data of the two-dimensional image, and then determining whether the acquired color information is included in a reference color range. When the acquired color information is included in the reference color range, image data remaining after deleting corresponding data from the two-dimensional image is converted into three-dimensional volume data. Meanwhile, when the reference color range is determined, a reference color may be pre-configured data or may be predetermined by a user, or learning for defining a reference color range may be performed through image data acquired by repetitively inputting reference images. By using the image filtering method, a three-dimensional scanner user can minimize post-correction work after scanning and acquire a precise data result value for an interior of the oral cavity, whereby data reliability is enhanced.

Abstract: The present invention relates to a digital scan body alignment method and a device using the same. The present invention corrects scan data through library data corresponding to image data on oral structure. At that time, to achieve best-fit of aligning the library data to the scan data initially, the data alignment can be performed by using a first alignment step. In order to accomplish data correction by more accurate data alignment, a second alignment step can be performed using the library data which includes shape information and axis information. By performing the second alignment step, corrected data having higher reliability can be formed, and a more precise prosthesis can be provided to a patient.
