Abstract

The invention provides a spectacle frame personalized design method based on facial form three-dimensional data, which comprises the following steps of: firstly, carrying out manual measurement or three-dimensional scanning on the face of a wearer, and establishing a geometric full view standard topology template of soft tissues around frame spectacles; further establishing a mathematical model capable of predicting static coincidence and dynamic stability of the optical axis of the frame glasses and the optical axis of the eyes; and finally, manually adjusting or customizing the glasses by using a 3D printing system, and evaluating the accuracy of the design process. According to the method provided by the invention, subjective qualitative customization of the glasses is changed into objective quantitative customization, manual operation is replaced by digitization and automation, the steps are simplified, the difficulty is reduced, and the finished glasses manufactured by the method are comfortable to wear and not easy to slip off.

Description

technical field [0001] The invention relates to the technical field of glasses design, in particular to a method for personalized design of glasses frames based on three-dimensional facial shape data. Background technique [0002] About 1 billion patients in my country correct their refractive errors by wearing glasses. The static coincidence and dynamic stability of the optical axis of the glasses and the visual axis of the eyes are important basis for evaluating the quality of glasses customization. At present, the ordering of frame glasses (mainly the frames) is manually adjusted after visual inspection. Affected by subjective factors such as the experience, skills, and operational stability of the eyewear ordering operator, the training process of the eyewear ordering operator is complicated, and the product production cycle is full. The length directly affects the custom-made quality of frame glasses. Contents of the invention [0003] The embodiment of the present i...
