Abstract: According to a data locking system and a data locking method, data obtained from a scanner is converted into a real-time three-dimensional surface having unit cells. The unit cells constituting the real-time three-dimensional surface include at least one piece of characteristic information having a variety of information such as color, curvature, reliability color, or data density. When new data is input from the scanner, after performing a real-time three-dimensional surface conversion and aligning process, the characteristic information assigned to the unit cells may be updated or update-restricted according to the characteristic information about a corresponding point. On the other hand, when a specific critical condition (a specific condition of the characteristic information) is assigned, there is an advantage of preventing unnecessary resources from being used in the process of forming an intraoral model by not updating the characteristic information even when new data is input for a corresponding unit cell.

Abstract: In an aligning method by grouped data according to the present disclosure, while initial grouped data is generated and a process of generating and aligning three-dimensional image data is performed, if a state in which pieces of three-dimensional volume data are not connected to each other continues for a predetermined time or longer, new grouped data is generated, so that at least one discontinuous grouped data may be generated. If three-dimensional volume data stored in new grouped data and three-dimensional volume data of previously generated grouped data are identified to have overlapping parts therebetween, an additional alignment step is performed to connect the overlapping parts to each other. As a result, a data gap is supplemented, and a patient's entire oral model data can be easily obtained.

Abstract: In method for replaying a scanning process according to the present invention, position information and rotation information of a scanner are acquired while scanning a scan target is a scanning step, and the distance relationship and angle relationship with the scan target can be calculated according to the position information and rotation information of the scanner. The acquired information and relationship values can be linked with a scan time and stored, and scanning data, along with the acquired information, can be sequentially displayed over time in a display step. According to the method for replaying a scanning process, the process of scanning performed by a user can be examined in chronological order, and the examination process can be quickly performed by controlling replay speed and selecting scan time. Accordingly, there are advantages in that the user can perform additional scanning of inadequately scanned portions, and the results of the scan can be used as material for deriving an optimal path for scanning when performing a scan on another patient having a similar oral cavity shape.
