Abstract

The invention discloses an intraoral three-dimensional scanning device and method. Wherein, the device includes: a projection module, which is used to project a preset pattern onto the measured object to form a projected image on the measured object, wherein the preset pattern is a color stripe pattern, and the measured object is teeth and / or gums The acquisition module is used to collect the projection image; the processing module is used to extract the feature points of the projection image using a preset algorithm, and obtain the three-dimensional data of the measured object according to the feature points, wherein the preset algorithm includes a stripe centerline extraction algorithm and / or or edge extraction algorithms. The invention solves the technical problem in the prior art that the intraoral scanner can only use powder spraying to reduce the impact of environmental factors such as teeth or saliva on the image clarity.

Description

technical field [0001] The present invention relates to the field of three-dimensional scanning, in particular to an intraoral three-dimensional scanning device and method. Background technique [0002] In the process of clinical oral diagnosis and restoration, oral impression is an important source of information storage. At present, digital impression technology with easy operation, high precision and convenient storage has attracted more and more attention from the field of stomatology. Digital impression acquisition The way of scanning can be divided into two categories according to the scanning position, namely extraoral scanning and intraoral scanning. Intraoral scanning can directly measure the tooth body by inserting the detector directly into the patient's mouth, and obtain digital impressions in real time, reducing operation time and reducing Material and labor consumption, so it has more obvious advantages. At present, when the intraoral 3D scanners used more in t...
