Embodiment 1

[0022] According to an embodiment of the present invention, a method embodiment of an intraoral three-dimensional scanning method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0023] figure 1 is an intraoral three-dimensional scanning method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0024] Step S102, using the first acquisition field of view to acquire the three-dimensional data of the user's full mouth teeth.

[0025] Specifically, the 3D data of the full mouth teeth here can be the 3D data of all the teeth of the user, or part of the teeth. The more teeth collected, the more co...

Embodiment 2

[0045] According to an embodiment of the present invention, a product embodiment of an intraoral three-dimensional scanning device is provided, figure 2 is an intraoral three-dimensional scanning device according to an embodiment of the present invention, such as figure 2 As shown, the device includes a first acquisition module, a first scanning module, and a first adjustment module, wherein the first acquisition module is used to acquire the user's full-mouth three-dimensional data using the first acquisition field of view; the first scanning module, It is used for three-dimensional scanning of the user's teeth, using the second acquisition field of view to acquire multiple single-piece three-dimensional data, wherein the first acquisition field of view is larger than the second acquisition field of view; the first adjustment module is used for three-dimensional The data is used as a frame, and multiple monolithic three-dimensional data are adjusted.

[0046] In the embodi...

Embodiment 3

[0057] According to an embodiment of the present invention, a storage medium is provided, and the storage medium includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to execute the above intraoral three-dimensional scanning method.

Abstract

The present invention discloses an intraoral three-dimensional scanning method and device. The method comprises the steps of: employing a first collection view field to obtain full mouth three-dimensional data; performing three-dimensional scanning of the user's teeth, and employing a second collection view field to obtain three-dimensional data of a plurality of single pieces, wherein the first collection view field is larger than the second collection view field; taking the full mouth three-dimensional data as a frame, and performing regulation of the three-dimensional data of the single pieces. The method and the device provided by the invention solve the technical problem that the full mouth whole scanning precision of the intraoral three-dimensional scanning product is low in the prior art.

Description

technical field [0001] The invention relates to the field of scanners, in particular to a method and device for intraoral three-dimensional scanning. Background technique [0002] At present, there are already many intraoral 3D scanner products on the market at home and abroad, whether it is video streaming or static camera type, due to the small working environment in the mouth, the range of teeth covered by a single piece of 3D data is relatively small (generally within 2 teeth) range), so it is necessary to splicing several single pieces of data through texture or geometric features, so there is bound to be a global error caused by the cumulative splicing error of several single pieces of 3D data, which affects the overall accuracy of the full-mouth data. At present, there are relatively Many literatures have evaluated the accuracy of intraoral 3D scanner products on the market. The accuracy of the 3D data of the whole mouth can be controlled at most 0.1mm, but it still c...
