In practical use, in an outdoor scene, for example, a scene such as a seaside or a mountain, a message board needs to be set, so that a user who passes through the scene is prompted, or information sharing and interaction among a plurality of users who pass through the scene are realized. However, when the message board is arranged in an outdoor scene, it is necessary to ensure that there is enough installation space and the firmness of the message board after installation, so that the installation process of the message board is complicated, the display space of the message board is limited to a certain extent, and the flexibility of message display is reduced.

To facilitate understanding of the embodiments of the present disclosure, a method for displaying a message board disclosed in the embodiments of the present disclosure will be described in detail first.
Referring to fig. 1, a flow chart of a method for displaying a message board according to an embodiment of the present disclosure is shown, the method includes S101-S104, wherein,
s101, determining current scene image information acquired by Augmented Reality (AR) equipment;
s102, judging whether a target AR message board matched with the current scene image information exists or not based on the current scene image information and the preset pose information of at least one AR message board in the constructed three-dimensional scene map;
s103, acquiring historical message information of at least one client corresponding to the target AR message board under the condition that the target AR message board exists;
and S104, displaying the historical message information on the target AR message board through the AR equipment.
In the method, whether a target AR message board matched with the current scene image information exists is judged through position and attitude information of at least one preset AR message board in a constructed three-dimensional scene map respectively based on the current scene image information; acquiring historical message information of at least one client corresponding to a target AR message board under the condition that the target AR message board exists; historical message information on the target AR message board is displayed through the AR equipment, the display of the target AR message board and the historical message information is achieved, the display of the target AR message board does not need to occupy real space, the display position is flexible, no safety problem exists, and the display device is more environment-friendly.
For S101:
here, an enhanced display (AR) device may be an intelligent device capable of supporting AR functions, and exemplary illustrations include but are not limited to: the mobile phone, the tablet computer, the AR glasses and other electronic equipment capable of presenting the augmented reality effect.
The current scene image information may be a captured current scene image, or may be feature information of a plurality of feature points extracted from the captured current scene image. Specifically, the current scene image may be acquired by the AR device, and after the current scene image is acquired, the current scene image information may be determined based on the current scene image. Namely, the shot current scene image can be determined as the current scene image information; alternatively, feature information of a plurality of feature points may be extracted from the current scene image by using a neural network algorithm, and the extracted feature information of the plurality of feature points may be determined as the current scene image information.
Here, when the execution subject is a client (AR device), the client may acquire a current scene image and determine current scene image information; when the execution main body is a server (the server may be a local server or a cloud server), the server may obtain the current scene image information from the client.
For example, while determining the current scene image information, the initial Positioning location information of the AR device obtained by Positioning through a Positioning sensor provided on the AR device may also be determined, for example, the initial Positioning location information of the AR device may be determined through a Global Positioning System (GPS) on the AR device.
For S102:
here, current three-dimensional pose information of the AR device may be determined based on the current scene image; and determining whether a target AR message board matched with the image information of the current scene exists or not by using the determined current three-dimensional pose information of the AR equipment and the pose information of at least one preset AR message board in the constructed three-dimensional scene map, namely determining whether the target AR message board capable of being displayed under the current three-dimensional pose information of the AR equipment exists or not. Wherein, the AR message board is the virtual message board established.
Here, when the execution subject is a server, the server may determine whether there is a target AR message board matching the current scene image information based on the acquired current scene image information and pose information of at least one preset AR message board in the constructed three-dimensional scene map. When the execution subject is a client, the client may determine whether a target AR message board matching the current scene image information exists based on the determined current scene image information and stored pose information of at least one preset AR message board in the constructed three-dimensional scene map. The three-dimensional scene map may be a pre-constructed three-dimensional scene model.
In an optional implementation manner, the determining, based on the current scene image information and pose information of at least one preset AR message board in the constructed three-dimensional scene map, whether a target AR message board matching the current scene image information exists includes:
the method comprises the steps of firstly, acquiring initial positioning position information of the AR equipment, which is obtained based on positioning of a positioning sensor;
secondly, judging whether candidate AR message boards exist within a first distance range from the AR equipment or not based on the initial positioning position information of the AR equipment and the preset position information of at least one AR message board in the constructed three-dimensional scene map;
if the AR equipment exists, determining accurate pose information of the AR equipment based on the current scene image information and the constructed three-dimensional scene map;
and fourthly, judging whether a target AR message board matched with the current scene image exists or not based on the accurate pose information and the pose information of the candidate AR message board in the three-dimensional scene map.
In step one, initial positioning location information of the AR device may be determined based on a positioning sensor, for example, initial positioning location information of the AR device may be determined based on a GPS, and the initial positioning location information may be location information of the AR device in a virtual coordinate system of a pre-constructed three-dimensional scene map. The virtual coordinate system is a coordinate system constructed based on a preset position in the three-dimensional scene map as an origin and a preset direction as a coordinate axis. The preset position corresponding to the origin and the preset direction corresponding to the coordinate axis can be set according to actual conditions, and specific limitation is not performed here.
In the second step, whether candidate AR message boards exist within a first distance range from the AR device may be determined based on the initial positioning location information of the AR device and the preset location information of each AR message board in the three-dimensional scene map.
Or, the moving distance between each AR message board and the AR device may be determined based on the initial positioning position information of the AR device and the preset position information of each AR message board in the three-dimensional scene map. And if at least one moving distance is smaller than the set first distance in the at least one moving distance, determining the AR message board with the moving distance smaller than the set first distance as a candidate AR message board. And if the AR message board with the moving distance smaller than the set first distance does not exist in the at least one moving distance, determining that the corresponding candidate AR message board does not exist at the initial positioning position information.
The first distance may be determined according to a display distance of the device, for example, if the AR device may display an object within 5 meters, the first distance may be determined to be 5 meters.
In the third step, when the candidate AR message board exists, accurate pose information of the AR equipment is determined based on the current scene image information and a pre-constructed three-dimensional scene map; and when the candidate AR message board does not exist, the process of determining the accurate pose information of the AR equipment is not executed.
In specific implementation, when the candidate AR message board exists, the accurate pose information of the AR device may be determined based on matching between the current scene image information and a pre-constructed three-dimensional scene map. The accurate pose information includes position information and orientation information of the AR device.
Here, the three-dimensional scene map may be constructed according to the following steps: acquiring a video corresponding to the scene, sampling the video to obtain a multi-frame scene sample, and extracting a plurality of feature point information from the multi-frame scene sample by using a neural network algorithm; and then, a three-dimensional scene map can be constructed based on the extracted multiple feature point information.
When the current scene image information is the current scene image, the feature information of a plurality of feature points corresponding to the current scene image can be extracted from the current scene image, and the accurate pose information of the AR device is determined based on the feature information of the feature points and the feature point information in the three-dimensional scene map. When the current scene image information is the feature information of a plurality of feature points corresponding to the current scene image, the accurate pose information of the AR device can be determined directly based on the current scene image information and the plurality of feature point information in the three-dimensional scene map.
In the fourth step, whether a target AR message board matched with the current scene image exists or not can be judged based on the accurate pose information of the AR equipment and the pose information of the candidate AR message board in the three-dimensional scene map; namely, when the AR equipment is in accurate pose information, whether a target AR message board capable of being displayed on the AR equipment exists or not is determined.
Here, since the calculation process of the accurate pose of the AR device is complicated, it is determined whether there is a matched candidate AR message board based on the initial positioning position information of the AR device, and the accurate pose information of the AR device is determined under the condition that it is determined that there is a matched candidate AR message board, and the target AR message board is selected based on the accurate pose information of the AR device, thereby avoiding some unnecessary calculation resource consumption.
For S103:
here, the cloud server (i.e., the server) stores history message information of at least one client corresponding to each message board. When a target AR message board exists, if the execution main body is a cloud server, the cloud server can acquire historical message information of at least one client corresponding to the target AR message board from a plurality of stored historical message information; if the execution main body is the client, the client can obtain the historical message information of at least one client corresponding to the target AR message board from the cloud server. The historical message information is a historical message published on the target AR message board by at least one client. Each piece of history message information may carry message leaving time, message leaving users, and the like.
For example, the AR device may periodically obtain, from the cloud server, the history message information generated by the target AR message board in the period, that is, obtain the history message information whose message time is in the period.
In an alternative embodiment, the method further comprises: and displaying prompt information indicating the azimuth information of the preset AR message board through the AR equipment under the condition that the target AR message board matched with the current scene image does not exist but the preset AR message board exists in a second distance range from the AR equipment.
Here, when the target AR message board does not exist, in a case where the preset AR message board exists within a second distance range from the AR device, a prompt message may be presented by the AR device, where the prompt message is direction information for prompting the preset AR message board. When the execution subject is a client, the prompt message may be generated on the client and presented on the client (i.e., the AR device). When the execution subject is the server, the prompt message may be generated on the server, and the prompt message may be sent to the AR device for presentation.
For example, the case where the target AR message board does not exist includes: a case where there is no candidate AR message board, and a case where there is a candidate AR message board but there is no target AR message board.
For example, in the case that there is no candidate AR message board, it may be determined whether there is a preset AR message board within a second distance range from the initial positioning position information of the AR device, and if there is the preset AR message board, prompt information indicating the azimuth information of the preset AR message board may be generated. For example, the generated prompt information indicating the azimuth information of the preset AR message board may be "north direction position, AR message board". Or when the preset AR message board exists, the prompt information corresponding to the preset AR message board may be generated based on the moving distance between the preset AR message board and the initial positioning position information of the AR device. For example, the generated prompt information indicating the direction information of the preset AR message board may be "prompt: north 5 m-AR message board ", see fig. 2a for an interface schematic of an AR device.
In the case that the candidate AR message board exists but the target AR message board does not exist, the candidate AR message board may be a preset AR message board, and then prompt information for the preset AR message board may be generated to prompt the direction information of the preset AR message board. Referring to fig. 2b, a prompt message "move right to see message board →" may be presented on the interface.
In the above embodiment, when the target AR message board does not exist and the preset AR message board exists within the second distance range from the AR device, the prompt message may be generated to prompt the direction of the preset AR message board, so that the user may display the preset AR message board by adjusting the pose of the AR device, and the exposure rate of the preset AR message board is increased.
For S104:
here, after obtaining the history message information of at least one client corresponding to the target AR message board, the target AR message board and the history message information on the target AR message board may be displayed on the AR device based on the pose information of the target AR message board in the pre-constructed three-dimensional scene map, the model information of the target AR message board, and the current scene image. The model information of the target AR message board can be stored on the AR device or in the cloud server.
In an optional implementation manner, the displaying, by the AR device, the history message information on the target AR message board includes: and under the condition that the number of the historical message information to be displayed is multiple, displaying the historical message information according to the set interval time. In one embodiment, all of the history message may be displayed, and thus each of the history message may be displayed at intervals. In another embodiment, a part of the message information can be selectively selected for presentation according to the requirement.
Here, the interval time may be set as needed, for example, the interval time may be 1 second, 3 seconds, 5 seconds, or the like. In specific implementation, if the interval time is 3 seconds, the next piece of history message information can be displayed after the current piece of history message information is displayed for 3 seconds, and then each piece of history message information in the history message information to be displayed can be displayed.
Wherein, show every historical message information according to the interval time that sets up, include:
and in the first mode, each piece of history message information is displayed in a rolling mode according to the set interval time.
And secondly, popping up each piece of history message information according to the set interval time.
In the first mode, when there are a plurality of pieces of history message information to be displayed, each piece of history message information may be displayed in a rolling manner according to a set interval time. Specifically, when each piece of history message information is displayed in a scrolling manner, the scrolling manner may also be determined, for example, the scrolling manner may include a scrolling speed and/or a scrolling direction. Wherein the scrolling speed and the scrolling direction can be determined as desired. The scrolling direction may be horizontal scrolling, vertical scrolling, etc.
In the second mode, each piece of history message information can be popped up according to the set interval time. For example, the history message information is popped up, and each piece of history message information may be randomly popped up at any position on the AR message board, and each piece of history message information popped up may be displayed for a fixed time (e.g., 3 seconds). Wherein, the font size, color and other text information of each piece of popped-up history message information may be fixed. Or the font size, color and other text information of each piece of popped-up history message information can be changed along with the lapse of the display time; for example, the font size of the history message information may be font size 8 between the 1 st second and the 2 nd second of the display; the font size of the history message information can be 10 font size between the 2 nd and 3 rd seconds of the display.
It will be appreciated that the two displays described above may also be used in combination. Namely, the left message information is displayed by adopting the first mode and the second mode at the same time.
In the above embodiment, the history message information is displayed in a scrolling manner, a popping manner, and the like, so that richer history message information can be displayed.
In an optional implementation manner, the displaying, by the AR device, the history message information on the target AR message board includes:
selecting target historical message information from the historical message information corresponding to the target AR message board according to the acquired attribute characteristics of each piece of historical message information.
And secondly, displaying the target historical message information on the target AR message board through the AR equipment.
Here, when the number of the history message information corresponding to the target AR message board is large, the target history message information may be selected from the history message information corresponding to the target AR message board according to the attribute characteristics of each piece of history message information. Wherein the attribute characteristics include at least one of: the message leaving time; the number of characters of message information; the repetition degree of the message information; author information; and (4) message information type.
Here, the selected target history message information is made more valuable by selecting the target history message information from the history message information by using at least one attribute feature, for example, when the attribute feature includes a message leaving time, the selected target history message information can be made more time-efficient as the history message information closer to the current time.
The message leaving time refers to the release time of the message leaving information. The number of characters of the message information may be the number of characters included in the message information. The message repetition degree may be a ratio of the character with the largest occurrence frequency in the message, for example, if the history message is "refuel, refuel", the message repetition degree is 50%. The author information refers to basic information of a user who issues a message. The message information type may include: advertisement information (information issued by an administrator), non-advertisement information, and the like.
For example, when the attribute feature includes a message leaving time, a preset number of message leaving information closer to the current time may be selected from the history message as the target history message. When the attribute feature includes the number of characters of the message information, the message information with the number of characters within the set number range can be selected from the history message information as the target history message information. For example, the set number range is 7-15 (including 7 and 15), and if the number of characters of the history message information a is 7, the history message information is the target history message information; if the number of characters of the history message information a is 5, the history message information does not belong to the target history message information. When the attribute characteristics include author information, the history message information of which the author information is widely recognized by the user can be selected as the target history message information. When the attribute feature includes a message type, the history message of which the type is the announcement message may be used as the target history message.
In the above embodiment, under the condition that there are many pieces of history message information, the target history message information can be screened from the history message information based on the attribute characteristics of each piece of history message information to be displayed, so that the history message information can be displayed with emphasis, the display mode is flexible, and compared with the mode that the history message information needs to be manually corrected when an entity message board is used, the history message information can be stored more completely, and the history message information can be selected to be displayed more flexibly.
In an alternative embodiment, the method further comprises: and acquiring message information input by a user in a target AR message board displayed by the AR equipment, and storing the message information in a cloud server.
Here, after the target AR message board is displayed, the message information may be input in the target AR message board, and the input message information and the target AR message board are associated and then stored in the cloud server, so that the AR device may obtain the message information from the cloud server and display the message information on the AR device.
In a specific implementation, when the history message is displayed on the AR device, the first history message input by the AR device may be distinguished from the second history message input by another client. For example, the font and color of the first history message are set to be different from those of the second history message; alternatively, an identifier may be added to the first history message. The identifier may be an underline, an identification figure, or the like.
In the above embodiment, the message information may be input in the target AR message board displayed by the AR device, so that the AR device and other clients may view the input message information, thereby implementing sharing of the message information.
Referring to fig. 3, an interface schematic diagram of an AR device is shown, where the interface schematic diagram includes a target AR message board 31, and "history message information a, history message information B, history message information C, and history message information D" are shown on the target AR message board, where the history message information D is message information input by the AR device, and therefore a font shown by the history message information D is different from other history message information, and an identifier is shown in the history message information D: and (c).
When the method for displaying the message board is applied specifically, the AR message board can be arranged in scenes such as tourist attractions (mountains, beaches and the like), entertainment places (such as a backroom escape game scene and the like), so that different users can check the arranged AR message board in the scene, and interaction and transmission of information are realized.
