Problems solved by technology
[0002] During the continuous scanning process of the buccal and lingual surface of various current intraoral 3D scanners, when the hand-held scanning head moves too fast, it is very easy to cause two adjacent images to be spliced normally and cause the scanning to be interrupted. The existing scanning technology requires Go back to the previous scanning position and re-scan to continue
Therefore, the clinical application efficiency is low, and both doctors and patients feel that the scanning process is complicated, time-consuming and not smooth

Embodiment Construction
[0014] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0015] see figure 1 , a non-interrupted scanning method for multi-dentate intraoral three-dimensional scanning of the present invention, comprising the following steps:
[0016] 1) First, perform a three-dimensional scan on the occlusal surface of the dentition, from one end point of the dentition, along the dental arch curve, to the end of the other side tooth by tooth, to obtain the occlusal surface and buccolingual surface of each tooth 3D surface data Do above the contour high point line;
[0017] 2) Then, scan the buccal and lingual sides of the dentition in the same sequence of teeth. If two adjacent images cannot be spliced at a certain point in the scanning process, use the buccal data in Do Or the tongue surface data is a common area, and the latest three-dimensional image at the above-mentioned time node is stitched to Do...

The invention relates to a non-interruption scanning method for multi-tooth-position intraoral three-dimensional scanning, which comprises the following steps of: scanning an occlusal surface part of a dentition from one side of the dentition to the other side of the dentition one by one to obtain data Do above a high point line of the occlusal surface and cheek-lingual surface appearance of each tooth; respectively scanning the buccal side surface and the lingual side surface of the dentition according to the same tooth position sequence, if two adjacent images cannot be spliced at a certain time node, splicing the latest three-dimensional image at the time node to the Do by taking buccal surface data or lingual surface data in the Do as a common region, and obtaining buccal surface data Db and lingual surface data D1 of the dentition without pausing the scanning operation; respectively registering the Db and the D1 with the Do, and supplementing scanning Dc for individual areas; and integrally fusing the Do, the Db, the D1 and the Dc, and obtaining complete scanning data of the dentition. The scanning interruption phenomenon of an existing intraoral three-dimensional scanner can be avoided, and the clinical application efficiency and the user experience are effectively improved.
Description
technical field [0001] The invention relates to a three-dimensional scanning structure, in particular to a non-interrupted scanning method for three-dimensional scanning in the mouth of multiple teeth. Background technique [0002] During the continuous scanning of the buccal and lingual surface of various current intraoral 3D scanners, when the hand-held scanning head moves too fast, it is very easy to cause two adjacent images to be spliced normally and cause the scanning to be interrupted. The existing scanning technology requires Go back to the previous scanning position and scan again to continue. Therefore, the clinical application efficiency is low, and both doctors and patients feel that the scanning process is complicated, time-consuming and not smooth. Contents of the invention [0003] The purpose of the present invention is to provide a non-interrupted scanning method for intraoral three-dimensional scanning of multiple teeth, which can avoid the frequent in...
