Method and device for scanning oral cavity by using smart phone and storage medium

Abstract

The invention discloses a method and a device for scanning an oral cavity by using a smart phone and a storage medium, the front end of a pick-up lens of the smart phone is connected with an external probe for transmitting images of teeth in the oral cavity, and a series of images with different depths of field in the oral cavity of a patient are obtained by high-speed photography while the offset of the lens of the smart phone is changed; the acquired image is processed to form a single-view depth image, the depth images of multiple views are converted into point cloud data, the point cloud data are spliced and gridded to form a final three-dimensional model, a real image of teeth in the oral cavity of a patient is transmitted into a smart phone to be restored into an oral cavity model, the cost of oral cavity scanning business is greatly reduced, and the oral cavity scanning efficiency is improved. The efficiency is improved.

Description

technical field [0001] The invention belongs to the field of digital intelligent equipment aided design of oral cavity modeling, and in particular relates to a method, device and storage medium for oral cavity scanning with a smart phone. Background technique [0002] In the process of clinical oral diagnosis and restoration, the method of obtaining a three-dimensional digital model of the oral cavity through three-dimensional scanning is mainly divided into two types: extraoral scanning and intraoral scanning. The extraoral scanning method requires the doctor to take an impression of the oral cavity to obtain a plaster model of the teeth, and then use a 3D scanning device to scan the plaster dental model to obtain its 3D digital model; the intraoral scanning method is to insert the oral scanner into the oral cavity and directly scan the teeth. Scan to obtain a three-dimensional digital model of the teeth. This method is simple, efficient and fast in measurement, thus saving...

At the same time, in order for the scanner to take images at the desired position without bumping into or hitting other parts of the oral cavity too often, the doctor's line of sight needs to constantly move between the oral cavity and the screen of the host computer station around him, resulting in reduced scanning efficiency and a large The host station causes the entire oral scanner system to take up a lot of limited space for diagnosis and treatment, and the cost is high
