Problems solved by technology
[0002] People pay more and more attention to oral health and prevention, and oral inspection has also entered people's lives. In the past, most of them relied on experienced doctors to observe the health of the oral cavity through the cooperation of mirrors and flashlights. However, for teeth, the target is small, and sometimes the reaction after the disease appears is not very intuitive, and the naked eye observation is prone to deviation, which is not conducive to diagnosis

The invention relates to the field of oral examination, in particular to an oral examination recognition method based on 3D scanning, which comprises the following steps: S1, acquiring a diseased tooth image through 3D scanning; S2, preprocessing the diseased tooth image, wherein the preprocessing comprises data labeling and sample separation processing; S3, performing machine deep learning training on the basis of the preprocessed diseased tooth image, and an algorithm model is established, wherein the algorithm model is a multi-scale algorithm model established by combining a backbone network with a target detection algorithm; and S4, performing diseased tooth recognition on the oral cavity scanning image to be recognized through the multi-scale algorithm model, constructing the multi-scale algorithm model by combining a residual network with a target detection algorithm, and performing two-stage detection through a two-stage loss function, so that the network has the capability of changing from coarse detection to fine detection.
Description
technical field [0001] The invention belongs to the field of oral examination, and in particular relates to an oral examination recognition method based on 3D scanning. Background technique [0002] People pay more and more attention to oral health and prevention, and oral inspection has also entered people's lives. In the past, most of them relied on experienced doctors to observe the health of the oral cavity through the cooperation of mirrors and flashlights. However, for teeth, the target is small, and sometimes the reaction after the disease appears is not very intuitive, and the naked eye observation is prone to deviation, which is not conducive to diagnosis. Contents of the invention [0003] The present invention provides a 3D scanning-based oral examination recognition method to solve the above problems, including the following steps: [0004] S1. Obtain images of diseased teeth through 3D scanning; [0005] S2. Preprocessing the diseased tooth image, the prepro...
