Embodiment Construction

[0024] The technical solution of the present invention will be explained more clearly and completely through the description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, a kind of dental model classification recognition method based on dental stl model and two-dimensional image registration of the preferred embodiment of the present invention comprises the following steps:

[0026] S1: Use an industrial camera to shoot the target dental model on the transmission line, obtain a two-dimensional image, and perform preprocessing on the two-dimensional image.

[0027] Specifically, an industrial camera is used in advance to collect the image when there is no dental mold on the transmission line as a background image and save it, and then an industrial camera is used to take pictures of the target dental mold on the transmission line to obtain the target image, and the background difference is ma...

Abstract

The dental model classification and recognition method based on the dental stl model and two-dimensional image registration comprises the following steps: S1, shooting a target dental model on a transmission line by using an industrial camera to obtain a shot two-dimensional image, and preprocessing the shot two-dimensional image; s2, performing perspective projection transformation on the three-dimensional model of the dental model three-dimensional stl file for printing the target dental model to obtain a transformed two-dimensional image; and S3, matching the shot two-dimensional image withthe transformed two-dimensional image, and identifying the dental model three-dimensional stl file corresponding to each target dental model, thereby realizing accurate sorting. The method can be used for quickly and accurately sorting a plurality of dental models produced in batches and matching the dental models with corresponding dental model three-dimensional files.

Description

technical field [0001] The invention relates to a dental model classification and recognition method based on dental STL model and two-dimensional image registration, belonging to the field of dental technology. Background technique [0002] With the widespread application of digital technology and 3D printing in the field of oral restoration, dental care has entered the digital age. In the process of digital preparation of dentures, it is necessary to prepare digital dental models. Due to the highly personalized characteristics of dental models, the use of 3D printing technology to make dental models has become the best choice. The popularization of 3D printing technology has shown huge commercial potential in the preparation of dental models. [0003] When 3D printers print dental models, in order to improve efficiency, they usually print multiple dental models in batches. And because there are often only slight differences between the dental models, after mass productio...
