Abstract
(EN) According to a data locking system and a data locking method according to the present invention, data obtained from a scan unit is converted into a real-time three-dimensional surface having unit cells, wherein the unit cells constituting the real-time three-dimensional surface include at least one of characteristic information having various information such as color, curvature, reliability of color, data density, etc. When new data is input from the scan unit, after performing a real-time three-dimensional surface conversion and alignment process, the characteristic information assigned to the unit cells may be updated or the update may be limited according to the characteristic information on a corresponding point. On the other hand, when a specific threshold condition (a specific condition of the characteristic information) is assigned, there is an advantage in that unnecessary resources are prevented from being used in the process for forming an oral model by not updating the characteristic information even when new data is input for a corresponding unit cell.
(FR) Selon un système de verrouillage de données et un procédé de verrouillage de données selon la présente invention, des données obtenues auprès d'une unité de balayage sont converties en une surface tridimensionnelle en temps réel ayant des cellules unitaires, les cellules unitaires qui constituent la surface tridimensionnelle en temps réel comprenant au moins une information caractéristique parmi des informations caractéristiques ayant diverses informations telles que couleur, courbure, fiabilité de couleur, densité de données, etc. Lorsque de nouvelles données sont introduites à partir de l'unité de balayage, après réalisation d'un processus de conversion en surface dimensionnelle en temps réel et d'alignement, les informations caractéristiques attribuées aux cellules unitaires peuvent être mises à jour ou la mise à jour peut être limitée en fonction des informations caractéristiques d'un point correspondant. D'autre part, lorsqu'une condition de seuil spécifique (une condition spécifique sur les informations caractéristiques) est attribuée, il existe un avantage qui est d'éviter l'utilisation de ressources non nécessaires dans le processus de formation d'un modèle oral par absence de mise à jour des informations caractéristiques même lorsque de nouvelles données sont introduites pour une cellule unitaire correspondante.
(KO) 본 발명에 따른 데이터 잠금 시스템 및 데이터 잠금 방법에 따르면, 스캔부로부터 획득한 데이터를 단위 셀을 가지는 실시간 3차원 표면으로 변환하고, 실시간 3차원 표면을 이루는 단위 셀들은 색상, 굴곡, 신뢰도색상, 자료밀도 등 다양한 정보를 가지는 특성정보 중 적어도 하나를 포함하고 있다. 스캔부로부터 새로운 데이터가 입력되면, 실시간 3차원 표면 변환 및 정렬(얼라인) 과정을 수행한 후 대응점에 대한 특성정보에 따라 단위 셀에 할당된 특성정보를 갱신하거나 또는 갱신제한할 수 있다. 한편, 특정 임계조건(특성정보의 특정 조건)이 할당되어 있는 경우, 대응되는 단위 셀에 대해서는 새로운 데이터가 입력되더라도 특성정보를 갱신하지 않도록 함으로써, 구강 모델 형성을 위한 과정에서 불필요한 리소스가 사용되는 것을 방지하는 이점을 가진다.
