Abstract

The invention provides a glasses automatic design method based on 3D head data. According to the glasses automatic design method based on 3D head data a camera matrix is adopted for acquisition of head characteristic information so as to obtain a plurality of head images, characteristic points from the plurality of head images are extracted, and head characteristic point cloud data is generated; ahead 3D model is constructed based on the point cloud data to realize acquisition of 3D head data; glasses frame design parameters are extracted based on the 3D head data, and a glasses frame 3D model is formed; glasses lens parameters are determined based on the eyesight situations of the two eyes and the glasses frame design parameters, a glasses 3D model formed based on the glasses frame modeland the glasses lens parameters is displayed, and parameters are adjusted based on the display effect to complete glasses design. The glasses automatic design method is capable of realizing customized automatic design and manufacturing of glasses; visible light camera matrix 3D scanning equipment control technology is adopted for head characteristic information collection, and acquisition efficiency and design accuracy can be increased obviously.

Description

technical field [0001] The invention relates to the technical field of data collection and intelligent manufacturing, in particular to an automatic design method for glasses based on 3D head data. Background technique [0002] In 2016, the National Bureau of Statistics conducted a survey of students' vision in schools across the country, showing that the myopia rate of primary school students was 27%, that of junior high school students was 53%, that of high school students was 72%, that of technical secondary school students was 50%, and that of college students was 88.48%. . However, there is a serious contradiction in China's glasses market: on the one hand, China has become the world's largest producer and consumer of glasses, and the domestic market for glasses is huge; on the other hand, the existing design and manufacture of glasses is still Simply referring to foreign glasses design methods, the design process is still dominated by Western head-shaped features. Dome...
