However, while the principles of the invention have been described in language specific to above, it is not intended to be limited to the specific form set forth herein, but on the contrary, it is to be understood that various steps and operations described hereinafter may be implemented in hardware.

The details will be described below separately.
The embodiment will be described from the perspective of an image display apparatus, which may be specifically integrated in a terminal, and the terminal may be an electronic device with two cameras, such as a mobile interconnection network device (e.g., a smart phone, a tablet computer).
Referring to fig. 1, fig. 1 is a schematic view of a scene framework of an image display method according to an embodiment of the present invention. The system comprises a terminal and a server, wherein the terminal and the server are in communication connection through the Internet.
When a user processes through a screen image display function in the terminal, the terminal can record input and output data in the processing process and then send the recorded data to the server, wherein the terminal can send the data to the server in a WEB mode or can send the data to the server through a client program installed in the terminal. The server can collect data sent by a plurality of terminals and process the received data based on machine deep learning so as to execute related functions.
Any of the following transmission protocols may be employed, but are not limited to, between the terminal and the server: HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), P2P (Peer to Peer, Peer to Server and Peer), P2SP (Peer to Server & Peer), and the like.
Referring to fig. 2, fig. 2 is a schematic flow chart of an image display method according to an embodiment of the present invention, where the image display method according to the embodiment includes:
and S101, acquiring at least two human body images through two cameras of the terminal.
In the embodiment of the invention, two different images of the same scene can be acquired through the two cameras on the terminal. For example, the terminal receives a photographing instruction input by a user, and opens the dual cameras according to the photographing instruction, and at this time, the dual cameras can acquire the two paths of image data.
As shown in fig. 3, since the two camera modules of the dual camera are located at different positions, the viewing ranges of the two camera modules are different, so that the images respectively acquired by the two camera modules are different. For example, one of the two camera modules is a wide-angle lens with 1600 ten thousand pixels, the other is a telephoto lens with 2000 ten thousand pixels, and the viewing range is b, which are not illustrated herein.
In one embodiment, the original image is obtained by shooting through two cameras. The original image may include images of a plurality of parts of a human body, a plant, a building, and the like, and a human body image may be further determined from two original images acquired by the two cameras, where the method for determining the human body image may be various, for example, a face image in the images is identified by a face identification technology, and then the human body image is determined. Face recognition is a biometric technique for identifying an identity based on facial feature information of a person. A series of related technologies, also commonly called face recognition and face recognition, are used to capture an image or video stream containing a face with a camera or a video camera, automatically detect and track the face in the image, and then perform face recognition on the detected face. In addition, the face recognition may use an adaptive boosting (adaptive boosting) algorithm based on Haar features to detect the face in the original image, or use another algorithm to detect the face in the original image, which is not limited in this embodiment.
In an embodiment, if there are a plurality of human body images in the images captured by the two cameras, feature information of the plurality of human body images may be extracted respectively, and a target human body image in the plurality of human body images may be determined according to the feature information.
And step S102, acquiring depth information of the human body according to at least two human body images.
In the embodiment of the invention, the mobile phone is provided with two cameras, wherein one camera is a main camera, the other camera is an auxiliary camera, the preview image shot by the main camera is a main preview image, and the preview image shot by the auxiliary camera is an auxiliary preview image. Because a certain distance or angle exists between the main camera and the auxiliary camera, a certain phase difference exists between the main preview image and the auxiliary preview image, and the depth of field of each pixel block or even each pixel point can be obtained by utilizing the phase difference. As shown in fig. 4, an original image and a depth image of a current scene, respectively. After the two cameras simultaneously acquire two images of the same scene, corresponding pixel points in the two images are found through a stereo matching algorithm, parallax information can be calculated according to a triangular principle, and the parallax information can be used for representing depth information of objects in the scene through conversion. Based on the stereo matching algorithm, the depth image of the scene can be obtained by shooting a group of images of different angles in the same scene.
In an embodiment, the method for obtaining the depth information of the human body may be various, for example, the depth information of a plurality of organ points of the human body may be obtained, and then the depth information of the human body may be generated according to the depth information of the plurality of organ points. Wherein, the organ points refer to contour points on the human organ, and each human organ can comprise one or more contour points. The human body image may include a plurality of organ points, such as a nose contour point, a face contour point, a mouth contour point, an eye contour point, an arm contour point, a leg contour point, and the like, which is not limited in this embodiment.
After the at least two human body images are acquired, the organ points in the human body images can be positioned to obtain at least one organ point. When organ points are located, the terminal may use algorithms such as ASM (active shape model), AAM (active appearance model), or SDM (supervisory descent algorithm) to locate. After obtaining the organ points in the human body image, the terminal can obtain the depth information of each organ point obtained by positioning through the double cameras.
The depth information of the organ point is used for indicating the distance from the organ point to the terminal, and the negative correlation relationship is formed between the depth information of the organ point and the distance from the organ point to the terminal, that is, the larger the image depth value of the organ point is, the closer the distance from the organ point to the terminal is indicated, the smaller the image depth of the organ point is, and the farther the distance from the organ point to the terminal is indicated.
In an embodiment, when the terminal shoots the organ point through the two cameras, the distance between the organ point and the terminal can be determined by adopting a triangulation method due to different angles between the organ point and the two cameras, and the depth information of the organ point can be determined according to the distance between the organ point and the terminal. After the depth information of a plurality of organ points is acquired, the depth information of the human body is further generated.
And step S103, establishing a three-dimensional image model of the human body according to the depth information of the human body.
In this embodiment, a three-dimensional image model of a human body may be established using a three-dimensional Reconstruction technique (3D Reconstruction). The three-dimensional reconstruction is to establish a mathematical model suitable for computer representation and processing on a three-dimensional object, is the basis for processing, operating and analyzing the properties of the three-dimensional object in a computer environment, and is also a key technology for establishing virtual reality expressing an objective world in a computer. Three-dimensional reconstruction builds surfaces by reconstructing three-dimensional coordinates in a computer, and therefore requires investigation of the points, lines, planes and their relationship to each other's position of the build object. The process of three-dimensional reconstruction of the human body can obtain the point cloud data of the human body by measuring the relative depth between the human body and the terminal, and the density of the point cloud directly determines the precision of the modeling object. And then, the surface shape of the human body can be finally obtained by searching and compensating the point cloud data. In addition, if the point cloud data of the human body contains color information on the position of the data point, color textures of the surface of the human body can be generated according to the neighborhood points of the point cloud.
And step S104, synthesizing the three-dimensional image model of the target virtual clothes and the three-dimensional image model of the human body to obtain the target three-dimensional image model.
In the embodiment of the invention, key points in the three-dimensional image model of the target virtual clothes can be extracted, and then the three-dimensional image model of the target virtual clothes and the three-dimensional image model of the human body are synthesized according to the key points. For example, the three-dimensional image model of the target virtual garment may be first divided into at least 5 model parts of the trunk, the left and right arms, and the left and right legs, then at least six key points of the crotch point, the left and right shoulder points, the left and right underarm points, and the neck reference point of the model are obtained from the divided model parts, and then the three-dimensional image model of the target virtual garment and the three-dimensional image model of the human body are synthesized according to the six key points to obtain the target three-dimensional image model.
And step S105, displaying the target three-dimensional image model.
In an embodiment, before the target three-dimensional image model is displayed, image preprocessing may be performed on an image of the model, and the preprocessing may include image enhancement, smoothing, noise reduction, and the like. For example, after an image of the target three-dimensional image model is obtained, information in the image can be selectively enhanced and suppressed to improve the visual effect of the image, or the image can be converted into a form more suitable for machine processing to facilitate data extraction or recognition. For example, an image enhancement system may highlight the contours of an image with a high pass filter, thereby enabling a machine to measure the shape and perimeter of the contours. There are many methods for image enhancement, such as contrast stretching, logarithmic transformation, density layering, and histogram equalization, which can be used to change image grayscales and highlight details.
As can be seen from the above, the image display method provided by the embodiment of the present invention may acquire at least two human body images through the two cameras of the terminal, acquire depth information of a human body according to the at least two human body images, establish a three-dimensional image model of the human body according to the depth information of the human body, synthesize the three-dimensional image model of the target virtual garment and the three-dimensional image model of the human body to obtain a target three-dimensional image model, and display the target three-dimensional image model. The terminal based on the double cameras can establish the three-dimensional image model of the human body of the user, and is synthesized with the three-dimensional image model of the clothes, so that the virtual fitting is carried out, and the real fitting effect can be obtained.
The image display method of the present invention will be further explained below based on the description of the above embodiment.
Referring to fig. 5, fig. 5 is another schematic flow chart of an image display method according to an embodiment of the present invention, including:
step S201, at least two human body images are collected through two cameras of the terminal.
Because the positions of the two camera modules of the two cameras are different, the sizes of the at least two images acquired by the two camera modules may be different, and the at least two images can be processed by the embodiment, so that the sizes of the images are the same. In an embodiment, after at least two human body images of the user are acquired through the dual cameras of the terminal, the method further includes:
selecting the image with the smallest size of at least two human body images as a reference image;
and compressing other human body images according to the size of the reference image so as to enable at least two human body images to be the same in size.
Step S202, the distance between two camera modules of the double cameras is obtained.
And step S203, generating parallax information between at least two human body images according to the distance.
In step S204, depth information of the human body is calculated according to the parallax information.
The mobile phone is provided with a double-camera device, wherein one camera is a main camera, the other camera is an auxiliary camera, a preview image shot by the main camera is a main preview image, and a preview image shot by the auxiliary camera is an auxiliary preview image. Because a certain distance or angle exists between the main camera module and the auxiliary camera module, a certain phase difference exists between the main preview image and the auxiliary preview image, namely parallax information, and the depth of field of each pixel block and even each pixel point can be obtained by utilizing the phase difference.
And step S205, establishing a three-dimensional image model of the human body according to the depth information of the human body.
In one embodiment, a three-dimensional Reconstruction technique (3D Reconstruction) may be used to create a three-dimensional image model of the human body. The process of three-dimensional reconstruction of the human body can obtain the point cloud data of the human body by measuring the relative depth between the human body and the terminal, and the density of the point cloud directly determines the precision of the modeling object. And then, the surface shape of the human body can be finally obtained by searching and compensating the point cloud data.
Step S206, acquiring position information of a first feature point in a three-dimensional image model of the target virtual clothes.
In an embodiment, before this step, a three-dimensional image model of the target virtual clothing needs to be obtained, specifically, an image of the target virtual clothing is obtained, then depth information of the clothing is obtained according to the image, and a three-dimensional image model of the target virtual clothing is established according to the clothing depth information. The image of the target virtual clothes can be obtained by shooting through the double cameras of the terminal, and can also be downloaded from a network database. That is, before the three-dimensional image model of the target virtual garment and the three-dimensional image model of the human body are synthesized, the method further comprises the following steps:
acquiring at least two virtual clothes images of a target virtual clothes;
and acquiring the depth information of the clothes according to the at least two virtual clothes images, and establishing a three-dimensional image model of the target virtual clothes according to the depth information of the clothes.
And step S207, determining corresponding second characteristic point position information in the three-dimensional image model of the human body according to the first characteristic point position information.
And S208, synthesizing the three-dimensional image model of the target virtual clothes and the three-dimensional image model of the human body according to the position information of the first characteristic point and the position information of the second characteristic point to obtain the target three-dimensional image model.
In step S209, the target three-dimensional image model is displayed.
In an embodiment, after displaying the target three-dimensional image model, the user may further adjust relevant parameters of the apparel, such as color, size, and the like, and the three-dimensional image model also makes corresponding adjustments, that is, after displaying the target three-dimensional image model, the method may further include:
receiving a clothing parameter adjusting instruction input by a user;
adjusting the target three-dimensional image model according to the clothing adjusting instruction;
and displaying the adjusted target three-dimensional image model.
In an embodiment, after the user views the target three-dimensional image model, the user may further query related information of the apparel, such as price, manufacturer, date of manufacture, and the like, and after displaying the target three-dimensional image model, the method may further include:
receiving a query instruction of a user for the target virtual clothing, wherein the query instruction carries attribute information of the target virtual clothing;
