Abstract

The invention provides a cephalometric trace diagram generation method and system. The method comprises the following steps of obtaining a head shadow picture to be measured; identifying the head shadow picture through an identification model to obtain sampling mark points; according to the sampling mark points, obtaining auxiliary mark points through a preset mode, wherein the preset mode comprises a template method; and performing curve fitting on the sampling mark points and the auxiliary mark points to obtain a cephalometric trace diagram. According to the method, the sampling mark pointsare automatically obtained through the identification model, the auxiliary mark points are obtained through the template method, the cephalometric trace diagram can be rapidly generated, and the workload of doctors is greatly reduced; and the accuracy of the cephalometric trace diagram obtained through the sampling mark points and the auxiliary mark points is high, medical risks caused by subjective reasons of the doctors are reduced, and doctor-patient disputes caused by the medical risks are avoided.

Description

technical field [0001] The present invention relates to the technical field of computers, and in particular, to a method and system for generating a cephalometric tracing graph. Background technique [0002] Cephalometric measurement technology was proposed by Broadbent and Hofrath respectively in 1931. It is to first draw a measurement trace on the lateral cephalometric film, and determine the measurement mark points, and then measure the line distance and angle drawn according to these measurement mark points. It is used to measure and analyze the ratio of line to distance to understand the structure of the soft and hard tissues of the skull, jaw, face, and teeth and their relationship with each other. [0003] Measurement trace Figure 1 Generally, the doctor manually delineates the X-ray head. This process requires a lot of work, and its accuracy is closely related to the doctor's responsibility and technical level. Therefore, the accuracy of the trace cannot be guarante...
