The embodiment of the application provides a virtual fitting method, a virtual fitting device, electronic equipment and a computer readable storage medium. Specifically, the virtual fitting method in the embodiment of the present application may be executed by an electronic device, where the electronic device may be a device such as a terminal or a server.

For example, the electronic device is described by taking a terminal as an example, and the terminal may acquire an image of a target object to be subjected to virtual try-on, where at least one garment is worn on the target object in the image of the target object; based on the image of the target object, carrying out grid reconstruction on the target object to obtain a three-dimensional model of the target object; determining a wearing area corresponding to the target clothing on the three-dimensional model based on the target clothing to be tried on by the target object; determining a part shielding area of a part matched with the target clothes in the image of the target object; and comparing the wearing area with the part shielding area, and performing virtual fitting of the target clothes on the target object based on a comparison result.
Based on the above-mentioned problems, embodiments of the present application provide a virtual try-on method, apparatus, electronic device, and computer-readable storage medium, which can improve the authenticity of virtual clothes after virtual try-on.
The following detailed description is provided with reference to the accompanying drawings. The following description of the embodiments is not intended to limit the preferred embodiments. Although a logical order is depicted in the flowchart, in some cases the steps shown or described may be performed in an order different than depicted in the figures.
In this embodiment, a terminal is taken as an example for illustration, and this embodiment provides a virtual try-on method, as shown in fig. 1, a specific flow of the virtual try-on method may be as follows:
101. an image of a target object to be subjected to virtual fitting is acquired, and at least one garment is worn on the target object in the image of the target object.
The target object is an object to be subjected to virtual test at present, and the object may be a person, an animal, or the like, and may be specifically set according to requirements, which is not limited herein. Correspondingly, the image of the target object can be a picture, namely, the virtual try-on is directly carried out on a picture containing the target object; the image of the target object may also be an image in a video, i.e. a virtual try-on is performed on the image in the video.
In this embodiment, before a virtual try-on is performed on a certain object, the terminal may wear some clothes, when a clothes consistent with a clothes type for performing the virtual try-on exists in the clothes worn by the object, the clothes worn by the object may be replaced with the clothes worn by the object, and when a clothes consistent with the clothes type for performing the virtual try-on does not exist in the clothes worn by the object, the clothes for performing the virtual try-on may be newly added to the object.
The clothing includes, but is not limited to, clothing, shoes, hats, accessories, hair accessories, etc., and may be specifically set according to the needs, and is not limited herein.
102. And carrying out grid reconstruction on the target object based on the image of the target object to obtain a three-dimensional model of the target object.
It can be understood that, since the image of the target object is only one two-dimensional image, in order to perform virtual fitting better, in this embodiment, the terminal may perform grid reconstruction on the target object based on the image of the target object, so as to obtain a three-dimensional model of the target object, that is, implement three-dimensional virtual fitting, so that the effect after fitting is more real.
Specifically, the terminal may directly perform grid reconstruction on the target object to obtain a three-dimensional model of the target object, or the terminal may send a request to the server, so that the server may perform grid reconstruction on the target object in response to the request, and feedback the obtained three-dimensional model of the target object to the terminal. Wherein the mesh reconstruction of the target object can be performed by neural network technology and smpl technology.
For example, as shown in fig. 2 and 3, for the target object in fig. 2, the terminal may obtain a three-dimensional model of the target image in fig. 3 by performing mesh reconstruction.
In some embodiments, the reconstructing the mesh of the target object based on the image of the target object to obtain the three-dimensional model of the target object may include: based on the image of the target object, carrying out grid reconstruction on the target object to obtain a plurality of three-dimensional vertex coordinates of the target object, namely, different three-dimensional vertex coordinates form different parts of a human body; and obtaining a three-dimensional model of the target object based on the three-dimensional vertex coordinates.
103. And determining a wearing area corresponding to the target clothing on the three-dimensional model based on the target clothing to be tried on by the target object.
The target clothes are clothes which are needed to be tried on currently by a target object.
It can be appreciated that, since the target garment described above may be applied to a portion of the target object, i.e., a local area of the target object, such as a chain ornament, may be applied to a wrist, ankle, etc. of the target object, in this embodiment, when the terminal is considered to face the local try-on, it is necessary to determine where the target garment is to be applied to the target object, i.e., which area of the three-dimensional model is to be applied, based on the garment that the target object currently needs to be tried-on.
The wearing area may be an area covered by the target garment on the target object, for example, the shoe may cover a foot area of the target object, and the bracelet may cover a wrist area of the target object.
In some embodiments, because the target apparel is different, the target apparel covers different areas on the target object, so the determining, based on the target apparel to be tried on by the target object, a wearing area corresponding to the target apparel on the three-dimensional model may include: acquiring attribute information of the target clothes; and dividing regions on the three-dimensional model based on the attribute information of the target clothing, and determining the region corresponding to the divided target clothing as the wearing region.
Wherein, the attribute information of the target clothes is related information for indicating the position where the target clothes is to be covered on the target object, for example, the attribute information of the target clothes can include, but is not limited to, size information for indicating the size of the target clothes and associated position information for indicating the position where the target clothes is to be applied, such as the foot of the target object.
In some embodiments, when the attribute information includes size information and associated location information, and the mesh reconstruction is performed on the target object based on the image of the target object to obtain the three-dimensional model of the target object, the obtaining a plurality of three-dimensional vertex coordinates of the target object during the reconstruction may be performed to obtain the three-dimensional model of the target object based on the plurality of three-dimensional vertex coordinates, and when the area division is performed on the three-dimensional model based on the attribute information of the target garment, and the area corresponding to the divided target garment is determined as the wearing area, may include: and the terminal determines the three-dimensional vertex coordinates of the target corresponding to the target clothes based on the size information and the associated position information of the target clothes, namely, determines the three-dimensional vertex coordinates to be covered by the target clothes as the three-dimensional vertex coordinates of the target. Then, the area composed of the three-dimensional vertex coordinates of the target is determined as the wearing area.
In some embodiments, since there may be a plurality of target clothes, in order to better distinguish different wearing areas of the three-dimensional model, after the area division on the three-dimensional model, the method may further include: different areas are divided into different colors so as to display the different color areas on the three-dimensional model, and thus the different color areas represent different target clothes, for example, the color in the color area corresponding to the left foot is red, and the color in the color area corresponding to the right foot is green.
For example, for the three-dimensional model in fig. 3, the terminal may divide different areas in the three-dimensional model and assign the divided different areas to different colors, as shown in fig. 4, resulting in the display of the different color areas on the three-dimensional model in fig. 4.
Specifically, the terminal may directly determine the wearing area corresponding to the target garment on the three-dimensional model, or the terminal may send a request to the server, so that the server determines the wearing area corresponding to the target garment on the three-dimensional model in response to the request, and feeds back the obtained wearing area corresponding to the target garment to the terminal. The terminal can adopt a pyrender library or other server rendering tools to realize the determination of the wearing area.
104. And determining a part shielding area of a part matched with the target clothes in the image of the target object.
It can be understood that, before the terminal performs virtual try-on a certain object, the object may be worn with some clothes, and shapes and sizes of different parts of different objects are different, so in this embodiment, in order to better improve the reality of virtual try-on, the terminal needs to perform recognition analysis on the target object, that is, analyze relevant information corresponding to each part of the target object based on an image of the target object, so as to determine areas corresponding to each part of the target object, that is, each local area of the target object, so that through analyzing each part of the target object, the problem of partial try-on of the target object, possibly resulting in peril, is simply and efficiently solved, thereby improving user experience.
The above-mentioned periencing problem may be, for example, a phenomenon that some positions of the target object are exposed, for example, a shoe is in the middle of the toes, which occurs when the shoe shape does not match the bones of the target object.
The above-mentioned portion shielding area is an area which corresponds to each portion and can be shielded, for example, a portion shielding area corresponding to the foot of the target object, and the portion shielding area needs to include an area corresponding to the shoe currently worn by the target object.
For example, for the target object in fig. 2, the terminal may determine the areas corresponding to the different parts of the target object by performing recognition analysis on the target object, as shown in fig. 5, where the different colors displayed in fig. 5 correspond to the areas corresponding to the different parts of the target object.
In some embodiments, because the target object in the image is further worn with some clothing when analyzing the target object, in order to better promote the reality of the virtual try-on, determining, in the image of the target object, the part shielding area of the part matching with the target clothing may include: and the terminal divides each part of the target object in the image of the target object and determines the part matched with the target clothes. Then, a portion matching the target clothing in the image of the target object is analyzed to obtain the portion analysis information, and the portion analysis information includes at least one of portion size information and size information of the portion wearing clothing. And finally, determining a part shielding area of the part matched with the target clothes based on the part analysis information.
Specifically, the terminal may directly determine the location shielding area of the location matching the target garment, or the terminal may send a request to the server, so that the server determines the location shielding area of the location matching the target garment in response to the request, and feeds back the obtained location shielding area to the terminal. The terminal can determine the position shielding area by adopting a neural network technology, for example, the terminal can obtain the position analysis information by adopting the neural network technology, such as information of a coat, trousers, left shoes, right shoes, a head, left legs, right legs, left arms, right arms and the like.
105. And comparing the wearing area with the part shielding area, and performing virtual fitting of the target clothes on the target object based on a comparison result.
In this embodiment, the terminal obtains a comparison result by comparing the wearing area with the above-mentioned portion shielding area, where the comparison result is used to indicate that the target object shields a portion of the target garment so as to implement the real situation of virtual fitting, if the wearing area is smaller than the above-mentioned portion shielding area, it indicates that the target garment cannot completely shield a portion of the target object, and if the wearing area is greater than or equal to the above-mentioned portion shielding area, it indicates that the target garment can completely shield a portion of the target object, so that based on the comparison result, virtual fitting of the target garment is performed on the above-mentioned target object, thereby solving the problem of peril occurring when performing virtual fitting of a certain local or global area.
In some embodiments, after the region division is performed on the three-dimensional model, the terminal may assign different colors to the divided different regions so as to display the different color regions on the three-dimensional model, so that the comparing the wearing region with the region shielding region may be performed by comparing the color regions, so as to increase the comparison speed, for example, comparing the color region corresponding to the wearing region with the region shielding region.
In some embodiments, the performing the virtual fitting of the target apparel on the target object based on the comparison result may include: if the comparison result shows that the wearing area is smaller than the part shielding area, and the target clothes cannot completely shield a certain part of the target object, repairing a difference area between the wearing area and the part shielding area in the image of the target object to obtain a repaired image. And then, acquiring the image of the target clothes, and fusing the image of the target clothes with the repaired image to realize virtual try-on of the target object.
In this embodiment, the terminal pointedly repairs the peril portion through image repair, thereby improving the reality of local virtual try-on and improving the user experience. The terminal can directly repair, and the terminal can also send a request to the server so that the server responds to the request to repair and feed the repaired image back to the terminal.
For example, for the wearing area of the right foot of the target object in fig. 4 and the position shielding area of the right foot of the target object in fig. 5, it can be seen that the position shielding area is significantly higher than the wearing area, and the difference area in fig. 6, that is, the black area in fig. 6, that is, the ankle area of the right foot can be obtained by comparison.
In some embodiments, the repairing the difference region between the wearing region and the region shielding region in the image of the target object to obtain a repaired image may include: based on the background area in the image of the target object, a background image is generated in which the target object is absent, as shown in fig. 7a, and a partial image of the difference area in the background image is determined. Then, the image corresponding to the difference region in the image of the target object is replaced with the partial image, so as to obtain a repaired image, that is, an image obtained after performing virtual fitting of the target apparel on the target object, as shown in fig. 7 b.
In this embodiment, the terminal directly compares the difference region between the wearing region and the region shielding region, that is, determines where the target object is exposed, that is, determines where the target garment is not matched with the target object, so as to avoid affecting the image of the target object after virtual try-on by updating the unmatched place as a background.
Specifically, if the difference region is set to be m_2, the background image is inp_1, the image of the target object (the image that is not subjected to virtual fitting) is img, the image of the target object is processed to obtain a repaired image new_img, that is, the formula of the image obtained by performing virtual fitting of the target apparel on the target object is as follows:
new_img＝m_2*inp_1+(1.0-m_2)*img
from the above, it can be seen that by acquiring an image of a target object to be virtually tried on, at least one garment is worn on the target object in the image of the target object. Then, based on the image of the target object, grid reconstruction is carried out on the target object to obtain a three-dimensional model of the target object, and based on target clothes to be tried on by the target object, a wearing area corresponding to the target clothes on the three-dimensional model is determined, and in the image of the target object, a part shielding area of a part matched with the target clothes is determined. Finally, comparing the wearing area with the part shielding area, and performing virtual fitting of the target clothes on the target object based on a comparison result, so that the wearing area corresponding to the target clothes and the part shielding area of the target object are determined to be compared, virtual fitting is performed based on a comparison result, and the authenticity of the virtual clothes after virtual fitting is improved.
In order to better implement the above method, the embodiment of the present application further provides a virtual fitting device, where the virtual fitting device may be specifically integrated in an electronic device, for example, a computer device, where the computer device may be a terminal, a server, or other devices.
The terminal can be a mobile phone, a tablet personal computer, an intelligent Bluetooth device, a notebook computer, a personal computer and other devices; the server may be a single server or a server cluster composed of a plurality of servers.
For example, in this embodiment, a specific integration of a virtual fitting device in a terminal will be taken as an example, and a method in this embodiment of the present application is described in detail, where this embodiment provides a virtual fitting device, as shown in fig. 8, where the virtual fitting device may include:
