[0002] In the traditional process of buying clothes, users need to constantly try on clothes to better view the effects of different styles. This process requires users to do it in person, so it takes up a lot of users' time. Due to the limitations of time and clothing resources, users may not be able to buy a piece of clothing that suits them in a day. Similarly, the process of users trying on clothes also takes up a lot of time and clothing resources of clothing stores, causing the store to lose a lot of profits. The existing virtual clothing try-on method usually obtains the user's body image and clothing image by shooting, and then matches the two to complete the online try-on. However, the human body image obtained by shooting cannot completely restore the user's body shape, and the clothing image cannot fit the user's real body well, resulting in a huge error in the try-on effect, and cannot provide users with a real try-on experience. Therefore, there is an urgent need for a virtual clothing try-on method that can truly restore the user's offline clothing try-on effect. Summary of the invention

[0019] Method Embodiment

[0020] According to an embodiment of the present invention, a real clothing fitting matching method for a virtual three-dimensional human body is provided. Figure 1 is a flow chart of a real clothing fitting and matching method for a virtual three-dimensional human body according to an embodiment of the present invention. Figure 1 As shown, the real clothing fitting and matching method for a virtual three-dimensional human body according to an embodiment of the present invention specifically includes:

[0021] Step S101, obtaining a three-dimensional human body model provided by a three-dimensional real human body simulation system, and generating a corresponding body shape label for the three-dimensional human body model according to a human body classification method;

[0022] The human body classification method is: dividing the human body shape categories according to the difference between the chest circumference and the waist circumference of the human body;

[0023] Step S102, obtaining a three-dimensional clothing image of the same body size through a model prop based on the body shape label;

[0024] Step S103, matching and docking the three-dimensional human body model with the three-dimensional clothing image according to the user's preferences and the user's body features, to obtain a real clothing try-on effect of the user;

[0025] The method further comprises:

[0026] Optimizing and adjusting the user's real clothing try-on effect to obtain an optimized real wearing form of the user, and presenting the real wearing form of the user in three dimensions, specifically includes:

[0027] Taking the acquired 3D human body model as the main body, the matched 3D clothing image is locally adjusted based on the five characteristic points of the human body to obtain the optimized user's real clothing try-on effect;

[0028] The five characteristic points of the human body include shoulders, chest, back, waist and buttocks;

[0029] Different forms of the three-dimensional clothing image are obtained, corresponding clothing forms are selected according to user needs, and the optimized user's real clothing try-on effect is adjusted according to the difference between the three-dimensional clothing images of different forms to obtain a real wearing form that satisfies the user.

[0030] The above technical solution of the embodiment of the present invention is described in detail below in conjunction with the specific situation of the real clothing try-on matching method for a virtual three-dimensional human body in the embodiment of the present invention.

[0031] The embodiment of the present invention provides a matching and docking method for simulating a three-dimensional real human body and achieving a real effect of trying on clothing, which specifically includes:

[0032] 1. Obtain a 3D real human body model provided by a 3D real human body simulation system, and set a human body classification, which is divided into Y, A, B, C, P, and P+ according to the chest-waist difference ratio of the human body, a total of 6 human body classifications (human body classification is not limited to these 6 cases, and the number of classifications can be adjusted according to market demand). Specifically, the above body classification codes are represented as follows:

[0033] a) Y body type means the difference between chest circumference and waist circumference is between 19cm and 24cm;

[0034] b) Body type A means the difference between chest circumference and waist circumference is between 14cm and 18cm;

[0035] c) Body type B means the difference between chest circumference and waist circumference is between 9cm and 13cm;

[0036] d) Body type C means the difference between chest circumference and waist circumference is between 4cm and 8cm;

[0037] e) P body type means the difference between chest circumference and waist circumference is between -1cm and 3cm;

[0038] f) P+ body type means that the difference between chest circumference and waist circumference is between -2cm and -6cm.

[0039] Among them, the three-dimensional real human body simulation system only requires the user to master his or her most basic height and weight to achieve three-dimensional human body restoration. The user can also customize the body shape details of the human body model according to his or her own personal characteristics, and ultimately restore a more realistic and appropriate three-dimensional real human body model for the user.

[0040] 2. The obtained virtual three-dimensional real human body of the user is labeled with a corresponding human body classification label according to the human body classification rules in the first article.

[0041] 3. Clothing image photography: According to the first human body type classification, obtain clothing images of the same size taken using model props;

[0042] The model prop is a device that can automatically retract and change the body shape for clothing photography, which includes:

[0043] (1) The model prop has a built-in electric controller;

[0044] (2) The body (the middle part of the body excluding the arms and legs) has 4 front, 1 side, and 4 back control points, for a total of 9 control scaling points;

[0045] (3) A row of horizontal control scaling points is set at the shoulders, chest, waist and hips of the body;

[0046] (4) There are four control points for the arms and legs, one in each of the four directions: front, back, left, and right;

[0047] (5) A row of horizontal control scaling points is set at the upper and lower ends of the arms and legs vertically and above and below the joints.

[0048] 4. Merchants on the shopping platform upload each style of the three-dimensional images of clothing for different human bodies to the platform server.

[0049] 5. When the user selects a clothing style, the software system automatically matches the corresponding three-dimensional clothing image according to the user's body classification label, and the user can view the effects of trying on different styles of clothing.

[0050] 6. The system automatically optimizes the matching three-dimensional image of clothing based on special human body classification.

[0051] 7. When performing matching optimization, the obtained virtual 3D real human body is taken as the main body (unchanged), and the 3D image of the clothing is continuously optimized and adjusted according to the local features of the virtual 3D real human body. Among them, the five parts of the human body with large changes in features are shoulders, chest, back, waist, and hips. The 3D image of the clothing and the virtual 3D real human body are based on the five highest points of the human body, and the highest point 15-25CM outward is over-optimized. Because the 3D clothing image taken by the model props is a standard human body shape, but the obtained virtual 3D real human body is a 100% restoration of the user's human body shape, it may have high and low shoulders, large or small chest, a slightly hunched back, a slightly thin waist, wide hips, etc. Therefore, after the 3D image of the clothing is matched with the virtual 3D real human body, the clothing after putting it on should be adjusted and optimized according to its human body characteristics, so that the clothing perfectly caters to the user's body shape, thereby presenting a more realistic try-on effect.

[0052] 8. For the waist and cuffs designed for clothing products (for example, a windbreaker can be worn either tight or untight), when shooting the three-dimensional image of the clothing, a group of photos will be taken for each style type provided by the merchant. For example, a group of photos will be taken for each of the tight and untight forms of a windbreaker and uploaded. When performing matching optimization, the virtual three-dimensional real human body will be used as the main body (unchanged). Users can choose different forms of the same clothing to try on. For example, a female user can try on two forms of a windbreaker. Then, based on the difference between the two groups of three-dimensional images of the clothing in tight and untight forms, the user's actual wearing form is optimized.
