Problems solved by technology

However, during the try-on process, the lens, an important part of the glasses, is not color-treated, especially consumers who have diverse needs for lens colors cannot meet their preview needs for the effect of tinted lenses, and the eyesight is damaged during the try-on process. The positioning detection is not accurate enough, and it is easy to fail the try-on

[0052] Data processor (2), this data processor (2) comprises data collector (21), image processor (22) and link builder (23), described data collector (21), image processor (22 ), the link generator (23) is coupled with the database (1) through interaction, and the data collector (21) is used to collect user information data, frame information data, lens color data and try-on effect data to the database (1 ), the image processor (22) calls the user information data, frame information data and lens color data in the database (1), parses the avatar through the user information data, and performs edge detection on the frame information data to obtain the frame image , and then use the lens color data to dye the inside of the frame, and output the adjusted glasses image and avatar respectively; the user interaction terminal (3) is used for man-machine interaction with the user to collect user information, and the user interaction terminal (3) is also coupled Connected to the data ...

Embodiment approach

[0057] The present invention provides another embodiment, a virtual try-on method, comprising the following steps:

[0058] Step 1, input the avatar and frame pictures into the database 1 through the user interaction terminal 3;

[0059] Step 2, carry out face recognition to the input avatar picture by the data processor 2, if the recognition is successful, then proceed to the next step, if the recognition fails, return to step 1 and re-input;

[0060] Step 3, through the data processor 2, perform pupil positioning on the avatar picture identified in step 2, and locate the pupil position of the face in the avatar picture;

[0061] Step 4: Translating and zooming the frame picture through the data processor 2, adjusting it to fit the size and position of the face in the avatar picture;

[0062] Step 5, through the data processor 2, the frame image adjusted in step 4 is used to identify the edge of the frame in it, and output a binary frame image;

[0063] Step 6, according to...

Abstract

The invention discloses a spectacle lens virtual try-on device based on edge detection. The device comprises a database, a data processor and a user interaction terminal, wherein the database stores user information data, spectacle frame information data, lens color data and try-on effect data; the data processor comprises a data collector, an image processor and a link generator; the user interaction terminal is used for performing human-computer interaction with a user for collecting user information, and the user interaction terminal is coupled to the data processor. According to the spectacle lens virtual try-on device based on edge detection, data can be effectively stored by setting the database so as to be processed by external equipment, the spectacle try-on effect can be achieved in a matched mode by setting the data processor and the user interaction terminal, color data is processed in the matched process of the data processor and the user terminal, the spectacle frame has colors during virtual try-on, and therefore the requirement for previewing dyed lenses can be effectively met.

Description

technical field [0001] The invention relates to a device for simulating glasses try-on, and more specifically relates to a virtual try-on device and method for glasses lenses based on edge detection. Background technique [0002] With the improvement of living standards, people's requirements for eyewear products have also changed from a single vision care to diversification, fashion, and individuality, and they have begun to pay more attention to the brand, style, color, and material of eyeglasses. However, it is difficult for some eye disease patients to see their own try-on effects clearly when choosing frames in an optical shop, let alone see the try-on effects of various lens colors in advance, which creates certain difficulties in the selection of frames and lenses. [0003] In the prior art, the computer is used as an auxiliary tool, and on the basis of the original business logic, digital image processing technology, including key technologies such as image synthesis...
