The embodiments of the present disclosure provide an image display method, an apparatus, a device, and a computer-readable storage medium, which can improve richness of image display and flexibility of image display control, where the image display method provided by the embodiments of the present disclosure is applied to a display device, and an exemplary application of the display device provided by the embodiments of the present disclosure is described below, where the display device provided by the embodiments of the present disclosure may be implemented as various types of terminals such as AR glasses, a notebook computer, a tablet computer, a desktop computer, a set-top box, a mobile device (e.g., a mobile phone, a portable music player, a personal digital assistant, a dedicated messaging device, and a portable game device). In a disclosed embodiment, the display device comprises a display screen, wherein the display screen is implemented as a movable display screen, for example, the display screen can be moved on a preset sliding track, or moved on a movable sliding support, or moved by a user holding the display device to implement the movement of the display screen.
Next, an exemplary application when the display device is implemented as a terminal will be explained. When the display device is implemented as a terminal, virtual effect data of a real scene object can be acquired from a preset three-dimensional virtual scene in an internal storage space of the terminal based on a display object in the real scene image, and an AR image effect combined with the virtual reality superposed with the display object in the real scene is presented according to the virtual effect data; the terminal can also interact with the cloud server, and virtual effect data are obtained through a preset three-dimensional virtual scene prestored in the cloud server. In the following, the description of the image display system is performed by taking the AR image effect as an example, in combination with a scenario in which a display object is displayed, in which a terminal acquires virtual effect data in an interactive manner with a server.
Referring to fig. 1-1, fig. 1-1 is an alternative architecture diagram of an image display system 100 provided by an embodiment of the present disclosure, in order to support a presentation application, a terminal 400 (which exemplarily shows a terminal 400-1 and a terminal 400-2) is connected to a server 200 through a network 300, and the network 300 may be a wide area network or a local area network, or a combination of the two. In a real display scene, such as historical relic display, sand table display, building display at a construction site, etc., the terminal 400 may be a display device arranged on a preset slide rail, or a mobile phone with a camera, wherein the mobile phone can be moved by being held by hand.

For example, when the terminal 400 is implemented as a mobile phone, a preset display application on the mobile phone may be started, a camera is called through the preset display application to collect a real scene image, and a data request is initiated to the server 200 based on a display object included in the real scene image, and after receiving the data request, the server 200 determines virtual effect data matched with the display object from a preset virtual three-dimensional scene model prestored in the database 500; and transmits the virtual effect data back to the terminal 400. After the terminal 400 obtains the virtual effect data fed back by the server, the virtual effect is rendered according to the virtual effect data through the rendering tool, and the virtual effect is superimposed on the target area of the display object in the real scene image, so that an AR effect image in a virtual-real combination manner is obtained, and finally the AR effect image is displayed on the graphical interface of the terminal 400.
In some embodiments, the server 200 may be an independent physical server, may also be a server cluster or a distributed system formed by a plurality of physical servers, and may also be a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, a middleware service, a domain name service, a security service, a CDN, and a big data and artificial intelligence platform.

The virtual effect of the exhibit can be at least one of introduction information of the exhibit, internal detail display information of the exhibit, an outline of the exhibit and a virtual interpreter of the exhibit. The movable display screen 101 is also provided with a front camera for shooting an interactive object (such as an exhibitor) in front of the movable display screen 101, and further, the movable display screen 101 can recognize an instruction sent by the interactive object in the shot image, so that the display and adjustment of the virtual effect of the exhibit are realized.
Based on the image display system and the application scenario, an image display method provided by the embodiment of the present disclosure is described, referring to the schematic flow diagram of the image display method shown in fig. 2, and the image display method provided by the embodiment of the present disclosure includes S210 to S240. Wherein the content of the first and second substances,
s210, acquiring multi-frame interactive images of interactive objects in the real scene through a plurality of first image acquisition devices.
The image display method provided in the embodiment of the disclosure is applied to a display device, wherein a display screen of the display device is a movable screen. The display screen of the display device may move on a preset sliding track as shown in fig. 3-1, or may slide by being fixed on a movable sliding support as shown in fig. 3-2.
In the embodiment of the present disclosure, the display device may include a plurality of first image capturing devices, where the first image capturing devices are capable of capturing images of an interactive object in a real scene, where the interactive object refers to an object capable of performing information interaction with the display device, and for example, the interactive object may be an exhibitor viewing display content in the display device, a user of the terminal device, and the like.
In this embodiment, the display device may process the interactive image acquired by the first image acquisition device, identify information such as pose information and expression information of the interactive object in the interactive image, and respond to an interactive instruction (for example, an instruction to enlarge a size of a display object in the display device and switch a virtual effect of the display object) sent by the interactive object, thereby implementing information interaction between the interactive object and the display device.
In some embodiments of the present disclosure, the first image capturing device may be a front camera of the display device, or may also be a rear camera of the display device, or may also be a camera disposed on a side surface of the display device. The setting position of the first image acquisition device in the display equipment is not limited in the embodiment of the disclosure.
In some embodiments of the present disclosure, a plurality of first image capturing devices may correspond to a plurality of frames of interactive images one to one, that is, one first image capturing device may capture one frame of interactive image. In addition, in the embodiment of the present disclosure, each of the plurality of first image capturing devices may also correspond to a plurality of frames of interactive images, that is, one first image capturing device may capture a plurality of frames of interactive images.
It should be noted that, in the embodiment of the present disclosure, the first image capturing device may be a fixed camera or a movable camera. The embodiment of the present disclosure does not limit the type of the first image capturing device.
S220, selecting a target interactive image from the multi-frame interactive images based on a specific selection condition.
In practical applications, a plurality of interactive objects around the display device may issue interactive instructions to the display device at the same time, and therefore, the display device cannot determine which interactive object responds to the interactive instructions.
Based on this, in the embodiment of the present disclosure, the display device may select one target interactive image from the collected multiple frames of interactive images according to a specific selection condition, so as to respond to the target interactive image. That is, the display apparatus may select an image satisfying a specific selection condition as a target interactive image from among the plurality of interactive images.
In some embodiments of the present disclosure, in order to improve the accuracy of the response, the display device may use factors such as image quality of an interactive object in the interactive image, and quality of a captured face as a specific selection condition for selecting the target interactive image.
In some embodiments of the present disclosure, the specific selection condition may include at least one of the following conditions:
the definition of the target interactive image is greater than a definition threshold value;
the number of the interactive objects in the target interactive image is greater than a first threshold value;
the number of interactive objects of which the visual lines are positioned on a display screen of the display equipment in the target interactive image is greater than a second threshold value;
and matching the target interactive image with a preset image.
The definition threshold, the first threshold and the second threshold are preset fixed values; or a value dynamically determined during the processing of the multi-frame interactive image, for example, the definition threshold may be a second highest definition value in the multi-frame interactive image. The disclosed embodiments are not limited herein.
Illustratively, the display device may compare multiple frames of interactive images, and select the interactive image with the largest image definition as the target interactive image; or the display device can also select the interactive image with the largest number of interactive objects as the target interactive image; the display equipment can also select the interactive image with the largest number of interactive objects with the sight focused on the display screen of the display equipment as a target interactive image; or the display device selects one interactive image matched with the preset image from the multi-frame interactive images as a target interactive image.
In another example, the display device may further select, as the target interactive object, an interactive image with the largest image definition and the largest number of interactive objects; or selecting the interactive image with the largest image definition and the largest number of interactive objects with the sight line focused on the display screen of the display equipment as the target interactive image.
In some embodiments of the present disclosure, when the specific selection condition includes more than two conditions, S120 selects the target interactive image from the multiple interactive images based on the specific selection condition, which may be implemented by:
s2201, determining the priority order of each condition in the specific selection conditions;
s2201, selecting a target interactive image from the multi-frame interactive images according to the priority order.
It is to be understood that, when a plurality of selection conditions are included in a specific selection condition, the display apparatus may select a target interactive image from the plurality of frames of interactive images in order of priority of each condition.
Illustratively, the specific selection condition includes three conditions, and the priority order is from high to low: the definition of the target interactive image is larger than a definition threshold value, the number of interactive objects in the target interactive image is larger than a first threshold value, and the number of interactive objects of a sight line in the target interactive image on a display screen of display equipment is larger than a second threshold value. In this way, after acquiring multiple frames of interactive images, the display device firstly selects an interactive image with the image definition greater than the definition threshold from the multiple frames of interactive images according to the condition of the highest priority (namely that the definition of the target interactive image is greater than the definition threshold), and if only one interactive image greater than the definition threshold exists, the interactive image is taken as the target interactive image; and if a plurality of interactive images with the definition threshold value are larger than the definition threshold value, the display equipment continuously selects the interactive images with the number of the interactive objects larger than the first threshold value from the selected interactive images with the definition threshold value larger than the definition threshold value based on a second condition of the priority (namely that the number of the interactive objects in the target interactive images is larger than the first threshold value). Similarly, if only one interactive image with the number of the selected interactive objects larger than the first threshold is available, the interactive image is used as a target interactive image, otherwise, the display device continues to select the interactive image with the number of the interactive objects with the sight lines on the display screen of the display device larger than the second threshold from the interactive images with the number of the selected interactive objects larger than the first threshold based on a third condition of the priority (namely that the number of the interactive objects with the sight lines on the display screen of the display device in the target interactive image is larger than the second threshold), and the selected interactive image is used as the target interactive image.
And S230, determining virtual effect data corresponding to the display object based on the target interactive image, and rendering the virtual effect data to obtain a virtual effect image.
The display object refers to image content corresponding to a real display object in a real scene image. Specifically, the display device may acquire an image of the real scene through the second image acquisition device to obtain a real scene image, and display the real scene image on a display screen of the display device.
It should be noted that the second image capturing device is different from the first image capturing device mentioned in S210. The second image acquisition device is used for acquiring images corresponding to the display objects in the real scene, and the first image acquisition device is used for acquiring images corresponding to the interactive objects in the real scene. Illustratively, the first image acquisition device is a front camera of the display device, and the second image acquisition device is a rear camera of the display device.
On the basis, when the interactive object watches the display screen of the display equipment, the display object displayed in the display screen can be watched; in this way, the interactive object may make an interactive instruction for the presentation object in the display screen, so that the display device responds to the interactive instruction by acquiring the interactive image of the interactive object.
In some embodiments of the present disclosure, the display device may identify image content of the target interaction image, determine an interaction instruction (e.g., a particular gesture, or a particular posture) of the interaction object, and determine virtual effect data to present in response to the interaction instruction.
In some embodiments of the present disclosure, the display device may further determine a target first image capturing device that needs to respond according to the target interaction image, and then continue to capture consecutive image frames through the target first image capturing device, so as to identify an interaction instruction (e.g., a specific gesture track) of an interaction object in the consecutive image frames, and determine virtual effect data to be presented in response to the interaction instruction.
In the disclosed embodiment, the virtual effect data is a set of virtual image data, which may be rendering parameters for rendering a virtual effect by a rendering tool. A virtual effect may be understood as a virtual object that is represented in an image of a real scene.
In an embodiment of the present disclosure, the virtual effect data may include at least one of:
the method comprises the steps of rendering a display object, virtually explaining the object, virtually representing the outline of the object, virtually representing the detail of the object and virtually representing the label.
The rendering model of the display object is a three-dimensional virtual model of the display object constructed based on the image information and the depth information of the display object. The three-dimensional virtual model can show objects in a real scene in a ratio of 1: 1, namely, if the three-dimensional virtual model is put into the world coordinate system where the real scene is located, the three-dimensional virtual model is completely overlapped with the target display object in the real scene.
The virtual explanation object refers to a virtual object that can interact with an interactive object located in front of the display device, such as a virtual interpreter and a virtual robot. For example, referring to a display interface diagram of an exemplary display device shown in fig. 4-1, the virtual explanation object may be a virtual interpreter 402 that explains a presentation object 401 in an image of a real scene.
The virtual object outline model is a virtual image which displays the outline of an object displayed in a real scene image in a key manner. For example, referring to the display interface diagram of an exemplary display device shown in fig. 4-1, the virtual object outline model may be a virtual contour line 403 outlining a display object 401 in the real scene image 400.
The virtual object detail model refers to the virtual detail display of the display object in the real scene image; for example, referring to the display interface schematic of an exemplary display device shown in fig. 4-2, the virtual object detail model may be a virtual detail presentation 405 inside a cultural relic 404 presented in the real scene image 400.
The virtual tag is used for displaying additional information of a display object in a real scene image; for example, referring to the display interface schematic of an exemplary display device shown in fig. 4-2, the virtual label may be detailed introduction information 406 corresponding to a cultural relic 404 shown in the real scene image, wherein the detailed introduction information may be "caliber 75.6 cm".
In the embodiment of the disclosure, after determining that the target interaction image is to be responded, the display device may acquire virtual effect data corresponding to the display object from the local storage space, or may acquire virtual effect data corresponding to the display object from a third-party device, for example, a cloud server. The embodiment of the present disclosure does not limit the manner of obtaining the virtual effect data.
And S240, displaying the augmented reality effect of the virtual effect image and the display object which are superposed on each other on the display equipment.
In the embodiment of the present disclosure, after the virtual effect data is rendered to obtain the virtual effect image, the display object in the real scene image and the virtual effect image may be superimposed, and the superimposed augmented reality effect may be displayed on the display device. In this way, when the user views the acquired real scene image on the display screen of the display device, the user can view the display object in the real scene image and the virtual effect superposed on the display object.
Therefore, the image display method provided by the embodiment of the disclosure acquires multi-frame interactive images of interactive objects in a real scene through a plurality of first image acquisition devices; further, based on a specific selection condition, selecting a target interactive image from the multi-frame interactive images; determining virtual effect data corresponding to the display object based on the target interactive image, and rendering the virtual effect data to obtain a virtual effect image; and finally, displaying the augmented reality effect of the virtual effect image and the display object which are superposed on each other on the display equipment. Therefore, the display equipment acquires the interactive images through the camera and selects one target interactive image from the multiple interactive images to respond according to a certain strategy, so that the interactive objects can operate the display equipment without contacting, and the interaction flexibility and accuracy are improved; in addition, the display equipment can obtain the virtual effect data of the display object according to the target interactive image, and adds the virtual effect on the display object for display, so that the display effect of the image is enhanced, and the richness of image display is improved.
Based on the above embodiments, there are various ways of determining the virtual effect data corresponding to the display object based on the target interactive image in S230, and two ways are described in detail below: mode one and mode two.
In the first mode, S230 determines virtual effect data corresponding to the display object based on the target interactive image, and may be implemented in the following manner:
s2301, identifying image content of the target interactive image, and determining posture information of an interactive object in the target interactive image;
and determining virtual effect data corresponding to the display object based on the posture information.
In the embodiment of the disclosure, after the target interactive image is selected and obtained, the display device may identify the image content of the target interactive image, determine an interactive instruction sent by the interactive object, and determine virtual effect data corresponding to the display object based on the interactive instruction.
In some embodiments of the present disclosure, the display device may determine the interaction instruction according to the recognized posture information of the interaction object. The gesture information may include gesture information and/or posture information.
Illustratively, the display device recognizes an interactive object display "OK" gesture from the target interactive image, that is, the interactive object is considered to expect to know the internal details of the display object in the current real scene image, so that the display device may obtain a virtual object detail model corresponding to the current display object according to the "OK" gesture, so that the rendered virtual effect image can display the internal details of the display object.
Therefore, the embodiment of the disclosure can respond by identifying the image content of the target interactive image, and can quickly respond to the image content of the target interactive image.
In the second mode, S230 determines virtual effect data corresponding to the display object based on the target interactive image, and may also be implemented in the following manner:
s2301', determining a target first image acquisition device corresponding to the target interactive image based on the target interactive image;
s2302', collecting at least two frames of images to be processed through a target first image collecting device;
s2303', based on at least two frames of images to be processed, virtual effect data corresponding to the display object is determined.
In practical application, the dynamic interaction instruction of the interaction object cannot be identified only through one target interaction image; for example, a user amplifies the interactive instructions of the virtual tag; therefore, it is necessary to determine the operation of the user over a period of time through a plurality of images.
In the embodiment of the disclosure, the display device may determine the first image acquisition device with a better acquisition effect according to the target interactive image. Here, the target first image acquisition device corresponding to the target interaction image is the first image acquisition device with a better effect.
In some embodiments of the present disclosure, after determining the target first image capturing device, the display device controls the first image capturing device to continue capturing multiple frames of images to be processed, determines an interaction instruction according to posture change information of an interaction object in the multiple frames of images to be processed, and determines virtual effect data corresponding to the display object based on the interaction instruction.
Illustratively, the display device acquires two continuous frames of images to be processed through the target first image acquisition device, and determines that the palm of the interactive object slides rightwards by identifying and comparing the two frames of images to be processed, namely, the interactive object is considered to expect to switch the additional information of the display object in the current real scene image; based on this, the display device can obtain the virtual tag to be displayed corresponding to the current display object according to the posture change information of the interaction object sliding rightwards by the palm, so as to display the additional information of the display object.
Therefore, the target first image acquisition device to be responded can be determined, the multi-frame image acquired by the target first image acquisition device is responded, the interactive instruction of the interactive object can be accurately determined, and the accurate determination of the response is improved.
Next, an exemplary manner of acquiring the presentation object is described.
In the embodiment of the present disclosure, before determining, based on the target interaction image, virtual effect data corresponding to the display object, the following steps may be further performed:
step a, acquiring a real scene image through a second image acquisition device;
b, identifying the image content of the real scene image to obtain a display object;
and c, displaying the display object on display equipment.
In the embodiment of the present disclosure, the display device may acquire an image of the current real scene in real time through the second image acquisition apparatus. The real scene may be a building indoor scene, a street scene, a specific object, and the like, in which a virtual object can be superimposed, and the virtual object is superimposed in the real scene to present an augmented reality effect.
In the embodiment of the disclosure, the display device may identify image content in the real scene image, obtain a display object in the real scene image, and display the display object.
