All other embodiments, which can be derived by a person skilled in the art from the embodiments of the disclosure without making creative efforts, shall fall within the protection scope of the disclosure.
In the related art, when a picture or a video related to a building is displayed, on one hand, a display space is needed for displaying, and on the other hand, the display method may be ignored by a user, and the display effect is poor.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In order to facilitate understanding of the present embodiment, a detailed description is first given of a display control method disclosed in the embodiments of the present disclosure, and an execution subject of the display control method provided in the embodiments of the present disclosure is generally a server.
The following describes the presentation control method provided by the embodiment of the present disclosure by taking an execution subject as a server.
Referring to fig. 1, a flowchart of a display control method provided in the embodiment of the present disclosure is shown, where the method includes steps 101 to 103, where:
The method comprises the steps that a target image including a target building is obtained through an AR device, the AR device can collect the image in real time and then send the image to a server, the server can detect the image to determine whether the image includes the target building, and if the image includes the target building, the image can be determined to be the target image.
In another possible implementation, the position information of the user can be detected in real time through the AR device, and when it is detected that the user enters a target position area, an image collected by the AR device is detected to perform detection, where the target position area is a position area where a target building can be shot, and if the user does not enter the target position area, the image shot by the AR device does not necessarily include the target building before the user enters the target position area, so that the detection on the images is not needed to reduce the amount of calculation.
In a possible implementation manner, when determining a target virtual display object matched with the target building in the target image, the attribute feature of the target building may be extracted based on the target image; and then selecting a virtual object matched with the attribute characteristics of the target building from all the virtual objects as the target virtual display object.
Wherein the attribute characteristics of the target building include at least one of:
size information, appearance information, construction information, color information, architectural style, architectural year, geographical location characteristics.
The size information may be a real size of the target building, and may specifically include a length and a width of the target building. When determining the size information of the target building, the pixel size information of the target building in the target image may be determined, and then the ratio between the preset pixel size and the real size may be determined, based on the pixel size information of the target building in the target image, to determine the real size information of the target building.

The geographical position characteristics of the target building can comprise position coordinates of the target building in a world coordinate system, and when the geographical position characteristics of the target building are determined, parameter information of a camera for acquiring the target image can be determined firstly; then determining a transformation matrix of an image coordinate system and a world coordinate system based on the parameter information; then determining the position coordinates of the target building under the image coordinate system; and finally, determining the geographical position characteristics of the target building based on the position coordinates of the target building in the image coordinate system and the transformation matrix.
The parameter information of the camera may include internal parameter information, external parameter information, distortion parameters, and the like, and when the parameter information of the camera for acquiring the target image is determined, the parameter information may be determined by a method for calibrating the camera.
In a possible implementation manner, when extracting the attribute features of the target building based on the target image, the target image may be input into a trained feature extraction network to obtain the attribute features of the target building, where the feature extraction network is trained based on a sample image carrying an attribute feature tag.
Specifically, when the feature extraction network is trained, the sample image can be input into the feature extraction network to be trained, the feature extraction network can output the predicted attribute feature of the target building, then the loss value in the current training process is determined based on the predicted attribute feature and the attribute feature label of the target building, when the loss value does not meet the preset condition, the network parameter of the feature extraction network in the current training process is adjusted, and the training process is executed again until the determined loss value meets the preset condition.
In another possible implementation, the corresponding relationship between each building and the virtual object may be directly set, and in determining the target virtual building matched with the target building in the target image, the target virtual building matched with the target building may be searched according to the corresponding relationship.
If the target virtual building matched with the target building is not found according to the corresponding relationship, in another example of the present disclosure, a similarity between the target building and each building in the corresponding relationship may be calculated, and then the virtual object corresponding to the building with the highest similarity is determined as the target virtual display object corresponding to the target building.
In specific implementation, after a target virtual display object matched with a target virtual building in a target image is determined, a display position of the target virtual display object can be determined, then according to the display position, the target virtual display object and a display scene where the target building is located are fused to generate AR data, and the generated AR data are displayed through an augmented reality AR device.
When the display position of the target virtual display object is determined, in a possible implementation manner, the display position of the target virtual display object may be determined according to geographic information features of the target building and a preset relative position relationship between the target building and the target virtual display object.
The relative position relationship between the target building and the target virtual display object can be a coordinate difference of the target building and the target virtual display object in a world coordinate system.
103, responding to a preset trigger instruction of the user for the target virtual display object, and controlling the AR equipment to display the AR animation special effect corresponding to the target virtual display object.
The preset trigger instruction comprises a limb posture trigger instruction and/or a sound trigger instruction.
The method includes the steps that a user responds to a limb posture trigger instruction of a target virtual display object, AR equipment is controlled to display an AR animation special effect corresponding to the target virtual display object, after the target virtual display object is displayed, a video including the target user is obtained, the limb posture of the target user in the video is detected, when the limb posture of the target user is detected to be consistent with a preset limb posture, a limb posture trigger instruction is generated and sent to a server, and the AR equipment is controlled to display the AR animation special effect corresponding to the target virtual display object according to the limb posture trigger instruction.
The method includes the steps that a sound trigger instruction of a user for a target virtual display object is responded, AR equipment is controlled to display an AR animation special effect corresponding to the target virtual display object, sound information collected by the AR equipment can be acquired after the target virtual display object is displayed, then voice recognition is conducted on the sound information, if target voice is detected in a recognition result, a sound trigger instruction can be generated and sent to a server, and the server can control the AR equipment to display the AR animation special effect corresponding to the target virtual display object according to the sound trigger instruction.
In a specific implementation, when responding to a preset trigger instruction of a user for the target virtual display object and controlling the AR device to display the AR animation special effect corresponding to the target virtual display object, after receiving a target trigger instruction in multiple preset trigger instructions initiated by the user, selecting a target AR animation special effect type corresponding to the target trigger instruction according to a mapping relationship between the multiple preset trigger instructions and the AR animation special effect types; and then controlling the AR equipment to display the AR animation special effect under the target AR animation special effect type corresponding to the target virtual display object.
The AR animation special effect corresponding to the target virtual display object may be to dynamically display the target virtual display object in different states, for example, if the target virtual object is an elephant, the AR animation special effect corresponding to the target virtual display object may be to swing a tail by the elephant.
Each target virtual display object may have a plurality of corresponding AR animation special effects, and the trigger instructions of the plurality of AR display special effects corresponding to the same target virtual display object may be different.
The controlling the AR device to display the AR animation special effect corresponding to the target virtual display object may be controlling the AR device to display an AR animation special effect corresponding to the target virtual display object and the preset trigger instruction.
Continuing the above example, if a preset trigger instruction corresponding to the elephant tail throwing is received, the AR equipment is controlled to display the AR animation special effect of the elephant tail throwing, and if the preset trigger instruction corresponding to the elephant nose throwing is received, the AR equipment is controlled to display the AR animation special effect of the elephant nose throwing.
In another possible implementation manner, there may be a plurality of target virtual display objects matched with the target building, and the preset trigger instructions corresponding to different target virtual display objects may be different, so that when responding to the preset trigger instruction of the user for the target virtual display object and controlling the AR device to display the AR animation special effect corresponding to the target virtual display, the target virtual display object corresponding to the preset trigger instruction of the target user may be determined from the plurality of target virtual display objects currently displayed, and then the AR device is controlled to display the AR animation special effect corresponding to the target virtual display object corresponding to the preset trigger instruction of the target user.
For example, if the target virtual display object matched with the target building may include a elephant and a bird, after receiving a preset trigger instruction of a user, it may be determined whether the target virtual display object matched with the preset trigger instruction is the elephant or the bird, and if the target virtual display object matched with the preset trigger instruction is the elephant, an AR animation special effect corresponding to the elephant is displayed.
In another possible implementation manner of the present disclosure, the target virtual display object may be stopped being displayed in response to a restore instruction for the target virtual display object. The restoring instruction may be an instruction generated by the user by triggering a restoring button on the AR device, or may be a preset default instruction, where the restoring instruction may also include a limb posture instruction and/or a sound instruction, and a method for specifically detecting whether the user triggers the restoring instruction is the same as a method for detecting whether the user triggers the preset triggering instruction, which will not be described herein again.
By the method, the target virtual display object matched with the target building can be displayed after the target image comprising the target building is acquired, and the display object is virtual, so that the method is not limited by space; the user can control the AR animation special effect corresponding to the target virtual display object by sending a preset trigger instruction, so that the interaction between the user and the target building is increased, the display mode is enriched, and the display effect is improved.
