Problems solved by technology
Compared with shopping in traditional stores, online shopping based on mobile platforms has the advantages of not being restricted by time and place, complete varieties, and low prices. However, the biggest disadvantage of online shopping is that the observation of products is not as comprehensive and intuitive as traditional stores.
Online shopping malls can usually only display products through pictures or videos, and it is difficult for customers to use this method to accurately select personalized products that suit them
[0003] Color contact lenses are a typical personalized product. Affected by the unintuitive online display, it is difficult for users to experience the real try-on feeling in the process of online shopping, so it is difficult to choose the personalized color contact lenses that suit them.
[0004] In order to solve the above problems, some schemes have proposed their own solutions, but the currently known solutions have shortcomings in accuracy and speed, and it is difficult to effectively apply them to mobile platforms such as mobile phones and tablet computers.

Embodiment 1
[0057] Such as figure 1 As shown, the manufacturing method of post-blurring processing virtual color contact lenses comprises the following steps:
[0058] Step S1, making an original image: obtaining a Base image with the characteristics of a color contact lens, the Base image being a png format image with an alpha channel.
[0059] The size of the Base image is 200*200. Taking a normal 960*1280 (iPhone front-end default pixel) selfie photo as an example, the head should be just included in the photo area when taking a selfie. The diameter of the iris may only be 30 to 40 About, present embodiment takes the diameter of iris as example with 30.
[0060] Step S2, resetting the picture size;
[0061] The specific process is:
[0062]Step C1, reading the iris size parameter in the target image.
[0063] Step C2: gradually reduce the original image A of the Base image according to the ratio until the size of the reduced image is smaller than the size of the iris. After install...

The invention discloses a production method and a display method of a post-blurring-processed virtual color contact lens, using two original basic color contact pictures, that is, a Base picture and a Mask picture, as samples, and the Base picture can guarantee the authenticity of its display effect to the greatest extent , while the Mask image uses multiplication to achieve the perspective effect, which can ensure the transparency of the display. The combination of the two can simulate the effect of wearing real color contact lenses to the greatest extent, and achieve a high-gloss, lifelike, glass material display effect. The design idea of segmented superposition is adopted, that is, the Base reset image is superimposed first, and then the Mask reset image is superimposed. The calculation formula is simple, the operation process is simple, and the entire operation can be performed quickly. It is a simple, fast, and high-performance overlay method.
Description
technical field [0001] The invention relates to the field of computer vision and virtual reality, and is a real-time virtual try-on technology for cosmetic contact lenses based on mobile platforms such as Android and iOS. Background technique [0002] With the in-depth development of the mobile Internet, more and more users begin to use mobile platforms such as mobile phones and tablets for online shopping. Compared with shopping in traditional stores, online shopping based on mobile platforms has the advantages of not being restricted by time and place, complete varieties, and low prices. However, the biggest disadvantage of online shopping is that the observation of products is not as comprehensive and intuitive as traditional stores. Online shopping malls can usually only display products through pictures or videos, and it is difficult for customers to use this method to accurately select personalized products that suit them. [0003] Color contact lenses are a typical p...
