Problems solved by technology

[0003] At present, relatively mature computer-aided systems such as Mimics 10.01 developed by Materialise can perform various practical operations on medical image sequences, while the measurement of base curvature data is mainly for left-right symmetrical images and two-dimensional images, and cannot be automatically processed. Extracting the contour of the image requires manual intervention, and the human operation has high requirements for the measurement personnel, resulting in inaccurate measurement of the base curvature data of the asymmetrical image and low measurement efficiency

Abstract

The invention discloses a method for measuring base curvature data of goggles based on medical images. , according to the image data, construct the 3D head skin model of the medical image; extract the 3D contour of the 3D head skin model according to the volume data field; convert the 3D contour into a symmetrical 2D contour, and measure the base Bending parameters; calculate the base bending value based on the base bending parameters. By adopting the embodiments of the present invention, the measurement accuracy and efficiency of base curvature data of asymmetric medical images can be improved.

Description

technical field [0001] The invention relates to the technical field of medical images, in particular to a method for measuring base curvature data of goggles based on medical images. Background technique [0002] Base Curve is the curvature of the wind-type goggles lens in the horizontal direction, and it has a quantitative index. The base curve of goggles on the market has only a few fixed values ​​according to different Eurasian races. People with different facial features and head characteristics may wear goggles with the same type of base curve value, which reduces the wearing comfort of Chinese people. To this end, measure and collect the parameters related to the calculation of the facial features of the human body and the base bending value of the goggles, and guide the design of goggles that are suitable for Chinese people to wear. The traditional measurement method is manual measurement, but because of many problems, it has been developed to measure by 3D visualiza...
