description The present invention relates to a three-dimensional intraoral scanner specifically comprising: a case which can be inserted into and withdrawn from the oral cavity, and has an opening portion which is open to allow the form of the inside of the oral cavity (hereinafter, referred to as an 'image') to be incident into the case in the form of light via an end portion thereof; at least one camera which is arranged inside the case to transmit the light incident via the opening portion of the case; a light projector which is arranged on one side of the at least one camera and emits light into the oral cavity via the opening portion; and a single polarized filter which is positioned between the at least one camera and the opening portion at a position spaced a set distance (d) from the front end of the at least one camera. Thus, the present invention provides the advantages of making it possible to manufacture a product having a slim size and improve the reliability with which an object to be measured can be measured.
