Embodiment Construction

[0057] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0058]The method for automatically marking the mandibular canal provided by the embodiment of the present application can be applied in the field of image processing technology, such as marking the three-dimensional panorama data of the periodontium in the actual and accurate marking of the mandibular canal data. However, the most important and time-consuming application in the above scenarios is how to improve the accuracy of marking the mandibular canal data in the periodontal three-dimensional panorama data. Therefore, how to accurately mark the mandibular canal data in the periodontal three-dimensional panorama data is a very important technical issue. ...

Abstract

The embodiment of the invention discloses an automatic marking method and device for a mandibular neural tube and electronic equipment. The method and device are used for marking mandibular neural tube data with high precision. The method comprises the following steps: acquiring first three-dimensional panorama data of a periodontal curved body; expanding the first three-dimensional panorama data into cuboid second three-dimensional panorama data; marking the second three-dimensional panorama data by using a trained 3D neural network model to obtain a mandibular neural tube; wherein the 3D neural network model is obtained by training based on three-dimensional panorama data of a cuboid marked with a mandibular neural tube; and mapping the marked mandibular neural tube to the first three-dimensional panorama data.

Description

technical field [0001] Embodiments of the present application relate to the technical field of image processing, and more specifically, relate to a method, device and electronic equipment for automatic marking of mandibular canal. Background technique [0002] The mandibular canal is an important anatomical structure in the human oral cavity. In the fields of implantation and orthodontics, accurate positioning of the neural tube is of great significance for tooth extraction, implant surgery and orthodontic treatment. The common way to locate the mandibular nerve tube is to manually mark the target points layer by layer on the 3D panorama, and then reconstruct the target points into a 3D model of the neural tube. [0003] With regard to the related technologies mentioned above, the inventor believes that the above marking method is not accurate and rather cumbersome. Contents of the invention [0004] The embodiments of the present application provide a method, device and...
