Description
Technical Field
The invention relates to the field of three-dimensional data processing, in particular to a display control method and computing equipment.
Background
With the development of AR (augmented reality) technology, its application in the fields of military affairs, medical treatment, entertainment, games, network video communication, etc. is more and more extensive. A typical application is virtual fitting, i.e. replacing real clothes worn by a user in an image of the user taken by a camera with virtual clothes, thereby displaying a three-dimensional effect of the user wearing the virtual clothes (or the virtual clothes being overlaid on the image of the user).
A common display scheme of virtual fitting is to combine an image of a user who has photographed the user with an image of clothes to be fitted, and in particular, to combine the image of clothes to be fitted onto the image of the user's body by changing the size of the clothes to be fitted based on body contour data on the image of the user's body, so that the virtual clothes to be fitted are always drawn in front of the body. The processing mode has two defects, namely, only the fitting effect of the front side of the user is displayed, so that the user cannot see the back side effect of the clothes during virtual fitting; secondly, when the front-back relationship between the body of the user and the clothes to be tried on is complex, it is difficult to properly generate a composite image, for example, when the hand of the user is in front of the trunk, the clothes to be tried on is also drawn in front, and the hand is hidden behind the clothes to be tried on, which is different from the actual trying effect desired by the user.
Therefore, an effective display control scheme is needed to solve the above problems and improve the user experience.

In recent years, a technique called Augmented Reality (AR) for overlaying additional information on the real world and presenting it to a user has received attention. Information to be presented to a user in AR technology can be visualized by using various forms of virtual objects such as text, icons, or animations. One major application of AR technology is to support the activities of users in the real world. Hereinafter, the AR technology is applied to the virtual fitting system.
Through the virtual fitting system using the AR technology, the user can experience virtual fitting in real time. According to the virtual fitting system of one embodiment of the present invention, the virtual clothes to be fitted can be displayed on the body of the user by acquiring the anteroposterior relationship (or referred to as an overlay relationship) of the clothes to be fitted and the body of the user.
Fig. 2 is a diagram illustrating an exemplary configuration scenario of a virtual fitting system 200 according to an embodiment of the present invention. An outline of the virtual fitting system 200 will be described below with reference to fig. 2.
In fig. 2, a virtual fitting system 200 includes an imaging part 210 for imaging a subject (i.e., a user), an image processing part 220 for "putting on" a virtual garment on the subject, and a display part 230 for displaying an image of the subject with the virtual garment. There is no particular limitation on the place where the virtual fitting system 200 is installed, and for example, the virtual fitting system 200 may be installed at a user's home or may be installed in a public place such as a brand store, a mall, an airport, a train station, or the like.
According to an implementation of the present invention, the imaging section 210 may include a photographing device (e.g., a camera) and a sensor. The photographing means is used to photograph an object existing in a real space, and in the example shown in fig. 2, a subject (e.g., a person) as a real space object is photographed by a camera. The sensor has a function of detecting a parameter from the real space, and transmits the detected data (e.g., depth data) to the image processing section 220. For example, the sensor may be constituted by an infrared sensor.
Alternatively, the imaging section 210 may employ a Kinect somatosensory camera. The Kinect somatosensory camera is provided with 3 lenses, and the middle lens is an RGB color camera and is used for collecting color images; the left and right lenses are an infrared emitter and an infrared CMOS camera, respectively, which form a 3D structured light depth sensor for collecting depth data (i.e., the distance from an object in the scene to the camera). The process and principle of the Kinect somatosensory camera for collecting the color image and the depth data of the measured object belong to the common knowledge in the field, and are not explained in detail herein.
It should be noted that the imaging part is not limited to the Kinect motion sensing camera, and any scheme capable of collecting the depth information of the scene in front of the shooting device (e.g., camera) is within the protection scope of the present invention.
According to an embodiment of the present invention, the image processing portion 220 and the display portion 230 may employ the computing device 100 to implement their functionality. The image processing part 220 synthesizes the virtual clothes to be tried on the photographed user body by the display control method of the present invention according to the data collected by the imaging part 210, and then the display part 230 displays the fitting effect.
Specifically, the image processing portion 220 calculates the position of the bone point of the user according to the user data (including, for example, the color image data and the depth data of the user) acquired by the imaging portion 210, and further constructs a three-dimensional model of the body of the user. Then, according to the obtained three-dimensional model of the clothes to be tried-on and the three-dimensional model of the body of the user, corresponding matching calculation is performed, the clothes to be tried-on are overlapped on the body of the user (for example, the clothes to be tried-on is bound to the skeleton points of the user), and the display part 230 displays the effect graph of the clothes to be tried-on of the user.
In some existing try-on effect displays, a penetration problem often occurs in the process of rendering and coloring a three-dimensional model of clothes and a three-dimensional model of a body of a user respectively, as shown in fig. 3A and 3B, fig. 3A is a normal effect diagram of trying on clothes by the user, fig. 3B is an effect diagram of improper penetration treatment, and as can be seen from fig. 3B, clothes and the body at the shoulders of the user are penetrated (a body part penetrates to the front of the clothes), and the clothes effect is not displayed correctly.
Next, a procedure in which the computing apparatus 100 executes the display control method 400 according to the embodiment of the present invention is described with reference to the flowchart of fig. 4.
The method 400 begins with step S410, obtaining a three-dimensional garment model of a garment to be tried on and a corresponding hollow template thereof.
According to one implementation of the invention, before the user tries on the clothes, all the clothes to be tried on are three-dimensionally modeled in batch: the depth data of the garment to be tried-on is acquired by using a camera and/or a sensor (such as the imaging part 210 described above), and then a three-dimensional model of the garment to be tried-on is constructed according to the depth data. According to one embodiment of the present invention, model batch-yield is performed in conjunction with KinectFusion. KinectFusion allows a user to hold and move a standard Kinect camera, and to quickly create a detailed 3D reconstruction of an indoor scene using depth data captured by the Kinect camera. The three-dimensional scanning and modeling of the garment to be tried-on are technical content disclosed in the art, and therefore, will not be described herein. It should be noted that the present invention is not limited to three-dimensional scanning and/or three-dimensional modeling by means of KinectFusion, and any means capable of three-dimensional modeling the clothes to be tried on or the body of the user can be combined with the embodiments of the present invention to complete the display control scheme of the present invention.
According to the implementation mode of the invention, for a certain type of clothes, the clothes three-dimensional models (S-size clothes three-dimensional model, M-size clothes three-dimensional model, L-size clothes three-dimensional model and the like) can be obtained by scanning the clothes with different sizes (S-size clothes three-dimensional model, M-size clothes three-dimensional model, L-size clothes three-dimensional model and the like); or only scanning the clothes with one size to obtain the three-dimensional clothes model, and then zooming to obtain the three-dimensional clothes models with other sizes. The embodiments of the present invention are not limited thereto.
Meanwhile, different models are selected to correspond to different clothes models or sizes, the model statues are used as original standard statues, and three-dimensional scanning and reconstruction are carried out on the bodies of the different models to construct a body three-dimensional model. For example, a three-dimensional body model corresponding to S code, a three-dimensional body model corresponding to M code …, and so on. According to the embodiment of the invention, the three-dimensional body model is constructed by referring to the process of constructing the three-dimensional garment model in the foregoing.
According to the embodiment of the invention, the hollow template corresponding to the clothes three-dimensional model is stored in the clothes three-dimensional model of each clothes to be tried on, and the hollow template represents the front-back relation of each vertex coordinate in the clothes three-dimensional model and the body three-dimensional model.
According to an implementation of the present invention, both the garment three-dimensional model and the body three-dimensional model established in advance may be stored in the image processing part 220. Or stored in a remote server, the server is connected to the virtual fitting system 200 through a network, and when the user wants to fit, the virtual fitting system 200 obtains the corresponding three-dimensional garment model and the corresponding three-dimensional body model stored in the remote server through a calling interface.
The process of the method 500 for creating a hollow template of a three-dimensional model of a garment will be described in detail below with reference to fig. 5.
In step S510, a second vertex in the three-dimensional model of the body that matches each first vertex in the three-dimensional model of the garment to be tried on is found.
Taking each vertex in the three-dimensional garment model of the garment to be tried on as a first vertex, finding a vertex in the three-dimensional body model of the user matched with each first vertex, taking the vertex as a second vertex, for example, traversing a certain vertex A on the left shoulder in the three-dimensional garment model of the S code of a certain garment to calculate the distance between the vertex A and the vertex B closest to the vertex A, namely the vertex corresponding to the left shoulder in the three-dimensional body model.
The process of finding matching vertices is described by the following example code segment:
in the code example above, the clothVtx and body vtx represent a garment three-dimensional model and a body three-dimensional model, respectively, both being three-dimensional arrays of the type Vextor 3. The distance calculation formula is not limited in the present invention, and any distance calculation formula of three-dimensional vectors can be combined with the embodiments of the present invention to implement the display control scheme of the present invention.
Subsequently, in step S520, the anteroposterior relationship between the first vertex and the second vertex is determined by the first vertex coordinate value and the matched second vertex coordinate value.
Specifically, the magnitude of the Z-axis value in the first vertex coordinate value and the Z-axis value in the matched second vertex coordinate value is determined: if the Z-axis value of the first vertex coordinate is less than the Z-axis value of the second vertex coordinate, indicating that the three-dimensional body model penetrated through the three-dimensional garment model at that vertex, then the second vertex was drawn before the matching first vertex; conversely, if the Z-axis value of the first vertex coordinate is not less than the Z-axis value of the second vertex coordinate, indicating that the three-dimensional model of clothing penetrated the three-dimensional model of the body at that vertex, then the first vertex was drawn before the matching second vertex.
Subsequently in step S530, a second vertex in the three-dimensional model of the body of the user covered by the clothing to be fitted is determined according to the context found in step S414. That is, when it is judged that the first vertex is drawn before the matched second vertex, the corresponding second vertex is covered by the clothing to be tried on, and at this time, the coordinate value of the second vertex is recorded.
Subsequently, in step S540, a stencil template is generated according to the determined coordinate values of the second vertex. In other words, the hollow template stores the vertex coordinates covered by the three-dimensional clothes model in the three-dimensional body model. According to one embodiment of the invention, the hollow template is in a JSON data format.
Optionally, the hollow template corresponding to the three-dimensional garment model of each piece of clothes to be tried on is stored in the three-dimensional garment model in an encrypted manner. When a user tries on a certain piece of clothes, the hollow template is read by adopting a corresponding decryption method while the three-dimensional clothes model of the clothes is obtained.
In step S420, transparent display processing is performed on the three-dimensional body model of the user according to the read hollow template, so as to obtain a hollow user body. According to one embodiment of the invention, Aphla values of the UV channels of the second vertexes recorded in the stencil template are all set to be transparent. Fig. 6A is a schematic diagram of a hollow-out user's body generated according to a hollow-out template of a certain piece of clothes to be tried on, and as shown in fig. 6A, the user's body is displayed in a transparent display manner on the upper body part of the user.
When a user selects a certain garment to be fitted to start fitting, the virtual fitting system 200 acquires depth data of the user's body via the imaging section 210, and constructs a three-dimensional model of the user's body from the depth data. The user may have a size that is different from the original standard size (i.e., the model size). In some extreme cases, it is possible that this difference may affect the subsequent display. Therefore, according to another embodiment of the present invention, the three-dimensional body model of the user is used as the current three-dimensional body model, the three-dimensional body model of the model collected in advance is used as the original three-dimensional body model, the current three-dimensional body model and the original three-dimensional body model are interpolated, the second vertex coordinates corresponding to the current three-dimensional body model are calculated according to the second vertex coordinates in the hollow template, and the corresponding hollow-out user body is generated according to the calculated second vertex coordinates in the current three-dimensional body model.
In the following step S430, the clothes to be tried on are overlapped on the hollow-out user body (for example, the three-dimensional clothes model is "tied" to the skeleton points according to the skeleton point positions of the three-dimensional clothes model), so as to show the effect of trying on the clothes by the user. As shown in fig. 6B, the display effect diagram of the clothes after fitting corresponding to fig. 6A is shown, and as shown in fig. 6B, the hollow part on the body is covered by the clothes corresponding to the three-dimensional model of the clothes, and the whole picture is not affected.
According to the display control scheme of the present invention, when a user tries to wear a certain piece of clothes, the virtual fitting system 200 acquires a hollow template while acquiring a three-dimensional model of the piece of clothes to be tried. The image processing part 220 performs corresponding transparent display processing on the three-dimensional body model according to the hollow template to obtain a hollow user body, then covers the clothes to be tried on the hollow user body, and the display part 230 displays the clothes trying on effect of the user. The problem of penetration during virtual fitting is effectively solved by transparent display of the body part covered by the garment.
In addition, due to the increase of hardware devices, people have higher and higher requirements on the fineness degree of the three-dimensional model. Since 2000k vertices are obtained when there are few beautiful garment models (or user body models), if matching operation is performed on the three-dimensional body model and the three-dimensional garment model of each user during fitting, the calculation amount increases by a geometric multiple, and in a few cases, hundreds of thousands of calculations are performed, and in a more case, millions of calculations are performed. This is a high cost for the user equipment overhead and the stuttering can affect the user's fitting experience. According to the display control scheme, the three-dimensional clothes model of the clothes to be tried on and the corresponding three-dimensional user body model are collected in advance, the hollow template is generated according to the front-back relation of the vertex coordinates of the hollow template, and the hollow template is stored in the three-dimensional clothes model. Therefore, the problem of system blockage caused by a large amount of calculation is effectively solved, meanwhile, most of places covered by clothes on the body are not calculated, and the whole picture display effect is not influenced.
