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.
