In a possible implementation manner, the virtual object display method in the embodiment of the present disclosure may be executed by an electronic device such as a terminal device or a server. Wherein, the terminal device may be User Equipment (UE), mobile device, user terminal, terminal, cellular phone, cordless phone, Personal Digital Assistant (PDA), handheld device, computing device, vehicle-mounted device, mobile phone, etc. Wearables and other devices. The server can be a single server or a server cluster composed of multiple servers. The electronic device may implement the virtual object display method of the embodiment of the present disclosure by the processor calling the computer-readable instructions stored in the memory.

The embodiments of the present disclosure can be applied to any application scenario in which virtual objects are displayed in an AR (Augmented Reality, augmented reality) image. For example, the application scene of displaying attractions or exhibits through AR scenes, or the application scene of game interaction through AR objects displayed in the AR scene. Optionally, the user terminal that displays the AR scene and the virtual object therein may be an electronic device that executes the virtual object display method of the present disclosure, or a device that is communicatively connected to the electronic device that executes the virtual object display method of the embodiment of the present disclosure.

FIG. 1 shows a flowchart of a method for displaying a virtual object according to an embodiment of the present disclosure. As shown in FIG. 1 , the virtual object display method according to the embodiment of the present disclosure may include the following steps S10-S30.

Step S10: Determine the first location information of the user terminal.

In a possible implementation manner, the user terminal may be an electronic device that executes the method for displaying virtual objects, or a device that is communicatively connected to the electronic device that executes the method for displaying virtual objects. The user terminal is used to display the AR scene and the virtual objects in the AR scene. The AR scene displayed by the user terminal may be a real scene corresponding to at least part of the scenes in the AR high-precision map. Three-dimensional reconstruction (SFM, StructureFrom Motion) was obtained. The first location information of the user terminal is used to represent the location of the user terminal in the AR high-precision map.

Optionally, the AR high-precision map is a three-dimensional virtual scene that restores a real physical scene. The process of determining the AR high-precision map may include acquiring continuous image sequences in the real physical scene, and then establishing a three-dimensional physical model for the real physical scene, and obtaining a three-dimensional virtual physical scene corresponding to the real physical scene as the AR high-precision map. Wherein, the real physical scene can be determined by a continuous image sequence obtained by collecting the real physical scene only with an image/video acquisition device such as a mobile phone or a camera. The three-dimensional physical model can be reconstructed by the SFM algorithm, that is, feature points are extracted from each frame of the continuous image sequence recording the real physical scene, and then the adjacent feature points in the multi-frame images are matched to obtain multiple three-dimensional points. Finally, the 3D virtual physical scene determined according to the 3D lattice composed of multiple 3D points is used as the AR high-precision map.

Further, the electronic device may determine the first location information when the user terminal is in an AR image display state. Wherein, the electronic device may determine that the display device is in the AR image display state when the image acquisition device built in the user terminal is in an on state. For example, if the user terminal and the electronic device are the same device, and the device is a smart phone, it is determined that the user terminal is in the AR image display state when the mobile phone is in a state where the camera is turned on, such as taking pictures or scanning. Alternatively, the electronic device may further determine that the display device is in an AR image display state when receiving the AR influence display request information sent by the user terminal.

In a possible implementation manner, the first location information of the user terminal may be determined according to the real environment where the user terminal is located. Optionally, the real environment image of the location can be collected by the built-in image acquisition device of the user terminal, and the first location information corresponding to the user terminal in the AR high-precision map is obtained by matching the real environment image with the AR high-precision map. For example, when the user terminal is a smart phone, when the mobile phone is in the AR image display state, the environment image is collected by the mobile phone camera, and then matched with the AR high-precision map deployed on the local or remote server to obtain the first location information.

Step S20: Determine the target virtual object to be displayed according to the first position information.

In a possible implementation manner, the AR high-precision map obtained by 3D modeling of the real physical scene has at least one corresponding virtual object, and the virtual object may be a two-dimensional object or a three-dimensional object. Each virtual object has a corresponding anchor point in the AR high-precision map, which is used to represent the display position of the virtual object. Optionally, at least one of the virtual objects may be selected as the target virtual object to be displayed according to the first position information of the user terminal, and the screening method of the target virtual object may be determined in any manner. For example, all virtual objects in the AR high-precision map where the first position information is located may be directly determined as the target virtual objects to be displayed. Alternatively, a corresponding map area may also be matched in the AR high-precision map according to the real environment image collected by the image collection device of the user terminal, and the virtual object anchored in the matched map area may be used as the target virtual object.

Optionally, each virtual object has a corresponding target area, the target area is used to represent an area in the AR high-precision map, and the electronic device can switch the virtual object according to the position of the user terminal in the AR high-precision map and the positional relationship of the target area. The display state of the object. Wherein, the target area can be an area of any shape. For example, the target area may be a circular area with the anchor point corresponding to the virtual object as the center and the preset size as the radius. The anchor point represents the second position information of the virtual object, that is, the corresponding display position of the virtual object in the AR high-precision map. Alternatively, the target area may also be other closed shapes such as squares and rectangles.

FIG. 2 shows a schematic diagram of a target area according to an embodiment of the present disclosure. As shown in FIG. 2 , the virtual object has an anchor point 21 representing the second position information in the AR high-precision map, and takes the anchor point 21 as the center of the circle, and the preset size is the radius to determine the circular target area 21 .

Step S30: Switch the display state of the target virtual object according to the first position information and the positional relationship of the target virtual object corresponding to the target area.

In a possible implementation manner, after determining the first position information of the user terminal and the target area of each target virtual object, the electronic device switches the target virtual object according to the positional relationship between the first position information and the target area of the target virtual object. The display state of the object in the AR image. Further, the user terminal displays the target virtual object in the AR image in a corresponding display state. The electronic device may switch the display state of the target virtual object in the AR image to the first state in response to the first position information of the user terminal being outside the target area of the target virtual object. Meanwhile, the electronic device may also switch the display state of the target virtual object in the AR image to the second state in response to the first position information of the user terminal being within the target area of the target virtual object. That is, when the position of the user terminal in the AR high-precision map is outside the target area of the target virtual object, the target virtual object is displayed in the AR image in the first state. When the position of the user terminal in the AR high-precision map is within the target area of the target virtual object, the target virtual object is displayed in the AR image in the second state.

Optionally, the first state is to display the target virtual object in the original size, and the second state is to not display the target virtual object, or to display the target virtual object in a display size smaller than the original size. Wherein, the original size may represent a preset display size of the virtual object, that is, a default setting.

Further, in practical application scenarios of augmented reality, the user terminal usually moves. In order to prevent the display state of the target virtual object from not being switched after the location of the user terminal in the AR high-precision map changes, it is also necessary to detect the first location information of the user terminal and switch the state according to the movement of the user terminal. Wherein, when the first position information is outside the target area of the target virtual object, the electronic device detects the first position information of the user terminal, and can move the target virtual object from outside the target area to the target area in response to the first position information. The display state of the object in the AR image is switched to the second state. In the case that the first position information is within the target area of the target virtual object, the electronic device detects the first position information of the user terminal, and can move the target virtual object from the target area to the outside of the target area in response to the first position information, and place the target virtual object in the target area. The display state in the AR image is switched to the first state.

When the first state is to display the target virtual object in its original size, and the second state is to not display the target virtual object, the difference between the display effect of the first state and the display effect of the second state is too large, and the visual experience of direct switching is poor. . Therefore, in the case that the target virtual object is not displayed in the second state, during the process of moving the first position information of the user terminal from outside the target area to the inside of the target area, and/or during the process of moving from inside the target area to outside the target area , the electronic device can switch the display state of the target virtual object in the AR image through a preset switching effect.

Optionally, the preset transition effects may include slide transition effects, such as any transition effects such as fading in and out, rotating and erasing. When there are multiple preset switching effects, the electronic device may randomly select one switching effect for display state switching at each state switching, or select one switching effect to perform display state switching according to a preset selection rule. Since the first state is to display the target virtual object in its original size, the second state is to not display the target virtual object. That is, the target virtual object appears in the AR image in the first state, and the target virtual object does not appear in the AR image in the second state. The effect switching method can make the appearance and disappearance of the target virtual object in the AR image more natural.

In the case where the first state is to display the target virtual object at the original size and the second state is to display the target virtual object at a display size smaller than the original size, the display size is positively correlated with the distance between the first position information and the second position information . That is to say, when the second state is that the target virtual object is displayed in a display size smaller than the original size, the closer the position of the user terminal in the AR high-precision map is to the anchor point of the target virtual object, the closer the target virtual object is in the AR scene. the smaller the display size. For example, after the user holds the user terminal and moves the user terminal and makes the first position information of the user terminal enter the target area of the target virtual object, the size of the target virtual object increases as the user terminal moves toward the anchor point of the object in the target area. The smaller the size, the larger the size of the target virtual object is when the user terminal moves away from the anchor point of the object in the target area. Optionally, the maximum display size of the target virtual object in the second state is the display size of the target virtual size in the first state. The electronic device may also set the minimum display size of the target virtual object in the second state, that is, after the display size of the target virtual object reaches the minimum display size, the display size of the target virtual object will not be reduced even if it approaches the anchor point again.

Further, since the first position information of the user terminal displays the target virtual object through different display states inside and outside the target area of the target virtual object, the electronic device can also detect that the first position information of the user terminal approaches the target area from the inside or the outside. Corresponding prompt information is generated at the edge to prompt the user that the display state of the target virtual object is about to be switched. Optionally, the prompt information may be notified to the user by means of voice broadcast, or displayed by the user terminal by means of text images or the like.

Based on the above content, the embodiment of the present disclosure can switch the display state of the target virtual object in the AR image according to the position of the user terminal in the AR high-precision map and the positional relationship of the target virtual object in the AR high-precision map. It is realized that when the user terminal is too close to the target virtual object, the entire screen will not be occupied, that is, the influence of the distance between the user terminal and the virtual object on the display effect of the virtual object in the AR image is reduced, and the user experience is improved.

It can be understood that the above-mentioned method embodiments mentioned in the present disclosure can be combined with each other to form a combined embodiment without violating the principle and logic. Those skilled in the art can understand that, in the above method of the specific embodiment, the specific execution order of each step should be determined by its function and possible internal logic.

Corresponding records will not be repeated.

In a possible implementation manner, the first state is to display the target virtual object in an original size, and the second state is to not display the target virtual object, or to display the target virtual object in a display size smaller than the original size For the target virtual object, the original size is the preset display size of the target virtual object.
