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
[0058] like figure 1 Shown, a kind of manufacturing method of virtual color pupil sheet, comprises the following steps:
[0059] Step S1, making the original picture: Obtain the Base picture with the characteristics of the color contact lenses, and obtain the Mask picture by multiplication. The value of each pixel of the RBG channel of the Mask picture is multiplied by 0.6. Both the Base picture and the Mask picture are png format pictures with an alpha channel.
[0060] The specific expression and calculation formula of the parameters of the Mask image is:
[0061] Mask1 r (i, j) = Base1r (i,j)*0.6;
[0062] Mask1 b (i, j) = Base1 b (i,j)*0.6;
[0063] Mask1 g (i, j) = Base1 g (i,j)*0.6;
[0064] where Mask1 r (i, j), Mask1 b (i, j), Mask1 g (i, j) form a Mask picture, the Mask picture is the picture obtained after processing, Mask1 r (i, j), Mask1 b (i, j), Mask1 g (i, j) respectively represent the value of the Mask image at the pixel coordinates (i, j) un...

The invention discloses a manufacturing method and a display method of a virtual color contact lens, using two original basic color contact pictures, that is, a Base picture and a Mask picture as samples, the Base picture can guarantee the authenticity of its display effect to the greatest extent, and the 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...
