In one example, the user terminal is a mobile phone, the image capturing module of the user terminal includes a camera module, and the mobile phone can capture the live-action image through the camera module. Of course, the live-action image may also be collected by an image collecting device connected to the user terminal. For example, the user terminal is a mobile phone, the image capturing device connected to the mobile phone is a camera, and the live-action image can be captured by the camera. The image capturing device and the user terminal may be connected in a wireless or wired manner, which is not limited herein.
In the embodiment of the present disclosure, the user terminal may acquire at least one of an image, an image sequence, a video, and the like for a real scene. Wherein the sequence of images may comprise at least two images. In a possible implementation manner, a real-scene image acquired by the user terminal for a real scene may be used as the first image. In another possible implementation manner, the live-action image may be compressed to obtain the first image. In another possible implementation, an image sequence including the live-action image may be taken as the first image. In this implementation, the live-action image may be the most recently acquired image in the sequence of images. In another possible implementation manner, an image sequence including the live-action image may be compressed to obtain the first image. In this implementation, the live-action image may be the most recently acquired image in the sequence of images. In another possible implementation, a video including the live-action image may be taken as the first image. In this implementation, the live-action image may be a newly captured video frame in the video. In another possible implementation manner, the video including the live-action image may be compressed to obtain the first image. In this implementation, the live-action image may be a newly captured video frame in the video.
In this disclosure, the user terminal may generate a virtual information acquisition request according to the first image, and send the virtual information acquisition request to the server. The server may acquire the first image by receiving the virtual information acquisition request, so that visual information of a real scene faced by the user terminal may be acquired. In the embodiment of the present disclosure, the target object in the first image may be any type of object having virtual information to be presented in the first image. For example, in an application scenario of AR exhibition at a museum, the target object may be a history object, a painting, etc. in the museum.
In a possible implementation manner, the acquiring, in response to the virtual information acquisition request, virtual information corresponding to a target object in the first image includes: responding to the virtual information acquisition request, carrying out object identification on the first image to obtain identification information of a target object in the first image; and acquiring virtual information corresponding to the target object according to the identification information of the target object. As an example of this implementation, feature extraction may be performed on the first image to obtain features of the first image; and matching the features of the first image with the features of at least one preset object, and in response to the matching of the features of the first image with the features of any preset object, using the identification information of the preset object as the identification information of the target object in the first image, that is, using the preset object as the target object in the first image. Wherein the preset object may represent an object having corresponding virtual information. The feature of the first image may be determined to match the feature of any preset object in a case where the similarity between the feature of the first image and the feature of the preset object is greater than or equal to a third preset threshold. The identification information of the target object may be information that can be used to uniquely identify the target object, for example, the identification information of the target object may be a number, a name, or the like of the target object. As an example of this implementation, a first neural network for object recognition may be trained in advance, the first image is input to the first neural network in response to the virtual information acquisition request, and the first image is subjected to object recognition via the first neural network, so as to obtain identification information of a target object in the first image. Of course, in other examples, a pre-designed function for object recognition or the like may be used to perform object recognition on the first image to obtain the identification information of the target object in the first image. In this implementation, by responding to the virtual information acquisition request, performing object recognition on the first image to obtain identification information of a target object in the first image, and acquiring virtual information corresponding to the target object according to the identification information of the target object, it is possible to accurately acquire virtual information that matches a live-action image currently acquired by the user terminal.
In another possible implementation manner, the acquiring, in response to the virtual information acquisition request, virtual information corresponding to a target object in the first image includes: responding to the virtual information acquisition request, and performing character recognition on the first image to obtain identification information of a target object in the first image; and acquiring virtual information corresponding to the target object according to the identification information of the target object. For example, in an application scenario of AR exhibition in a painting and calligraphy exhibition hall, the painting and calligraphy displayed in the painting and calligraphy exhibition hall usually contain text information. In this case, by performing character recognition on the first image in response to the virtual information acquisition request, the identification information of the target object in the first image can be quickly and accurately obtained, and thus the virtual information that matches the target object in the live-action image currently acquired by the user terminal can be quickly and accurately obtained.
In the embodiment of the present disclosure, the virtual information may represent virtual information for displaying after being fused with information of a real scene. The virtual information may include one or more of text, picture, audio, video, and the like. For example, the virtual information corresponding to the target object in the first image may include text and/or video for introducing the target object. For another example, the target object in the first image is a drawing a containing a character a, and the virtual information corresponding to the target object may include a video of the character a walking in the drawing a. For another example, the target object in the first image is a landscape ancient painting B, and the virtual information corresponding to the target object may include videos of leaf shaking, river flowing, animal walking, and the like in the landscape ancient painting B.
In the embodiment of the disclosure, a target plane for displaying the virtual information may be determined according to the simplified first image, and a mapping relationship between a first coordinate system corresponding to the target plane and a screen coordinate system of the user terminal may be determined according to the position information of the target plane, so that the target plane for displaying the virtual information may be determined quickly and accurately based on the simplified first image, and thus the method may be applied to a complex scene, may facilitate to identify and track a target object more quickly and accurately in the complex scene, and may further complete a display processing process of the virtual information in a real scene quickly and accurately.
In a possible implementation manner, the simplifying the first image to obtain a simplified first image includes: detecting an object which meets a preset simplification condition in the first image; in response to detecting the object meeting the preset simplification condition, removing the object meeting the preset simplification condition from the first image to obtain a simplified first image. In this implementation, the preset simplification condition may represent a preset condition for simplifying the first image. In this implementation, the object satisfying the preset simplification condition may be removed from the first image by way of matting, setting the transparency to 100%, or adding a mask, etc. The object meeting the preset simplification condition in the first image is detected, the object meeting the preset simplification condition is removed from the first image in response to the detection of the object meeting the preset simplification condition, the simplified first image is obtained, the object meeting the preset simplification condition in the first image can be removed, the object which does not meet the preset simplification condition in the first image is reserved, the target plane for displaying the virtual information can be rapidly determined based on the first image after the object meeting the preset simplification condition is removed, and the target plane for displaying the virtual information can be accurately determined based on the object which does not meet the preset simplification condition and is reserved in the first image.
As an example of this implementation, the preset simplifying condition includes: the number of the characteristic points reaches a first preset threshold value and is not matched with an object to be marked in the target object. In this example, the target object may include one or more objects to be tagged. In this example, for any object in the first image, if the number of feature points of the object does not reach the first preset threshold, it may be determined that the object does not satisfy the preset simplification condition. If the number of the feature points of the object reaches a first preset value, calculating the similarity between the object and an object to be marked in the target object; if the similarity between the object and any object to be marked in the target object is greater than or equal to a fourth preset threshold, the object can be judged to be matched with the object to be marked, and therefore the object can be determined not to meet the preset simplifying condition; if the similarity between the object and each object to be marked in the target object is smaller than a fourth preset threshold, it can be determined that the object is not matched with each object to be marked of the target object, so that the object can be determined to meet the preset simplification condition. For example, the target object is a drawing a, and the target object includes 3 objects to be marked, namely a bridge b, a house c and a ship d. If the number of the feature points of the object reaches a first preset threshold and the similarity between the object and the bridge b is greater than or equal to a fourth preset threshold, matching the object and the bridge b, namely, judging that the object is the bridge b, and thus determining that the object does not meet the preset simplification condition; if the number of the feature points of the object reaches a first preset threshold value and the similarity between the object and the bridge b, the house c and the ship d is smaller than a fourth preset threshold value, it can be determined that the object is not matched with each object to be marked of the target object, and therefore it can be determined that the object meets the preset simplified condition. This example obtains a simplified first image by detecting an object in which the number of feature points in the first image reaches a first preset threshold and which does not match an object to be marked in the target object, and in response to detecting that the number of feature points reaches the first preset threshold and which does not match the object to be marked in the target object, removing the object in which the number of feature points reaches the first preset threshold and which does not match the object to be marked in the target object from the first image, whereby the speed and accuracy of determining the target plane for displaying the virtual information can be further improved.
It should be noted that although the preset simplification condition is described above by taking "the number of feature points reaches the first preset threshold and does not match the object to be marked in the target object" as an example, the skilled person can understand that the disclosure should not be limited thereto. The preset simplifying conditions can be flexibly set by those skilled in the art according to the requirements of practical application scenarios. For example, the preset simplifying condition may include: the area is smaller than or equal to a fifth preset threshold and is not matched with the object to be marked in the target object. As another example, the preset simplification conditions may include: the area is less than or equal to a fifth preset threshold. As another example, the preset simplification conditions may include: the target object belongs to a preset object type and is not matched with an object to be marked in the target object. As another example, the preset simplification conditions may include: belonging to a preset object type.
In another possible implementation manner, the simplifying the first image to obtain a simplified first image includes: detecting an object belonging to a preset object type in the first image; in response to detecting the object belonging to the preset object type, removing the object belonging to the preset object type from the first image, resulting in a simplified first image. In this implementation manner, the preset object type may be flexibly set according to an actual application scenario. For example, an object type that easily affects recognition of a target object may be set as the preset object type. For example, the preset object type may be a tree, a flower, a crowd, and the like.
In the embodiment of the present disclosure, a target plane for displaying the virtual information may be determined according to the simplified first image by a marker-less method, a marker-based method, or the like. Wherein the target plane may also be referred to as a plane reference. By adopting the marker-less method, a template card or a two-dimensional code does not need to be manufactured in advance, so that the determination of the target plane can be facilitated. The marker-less or marker-based technology in the related art needs to consume a large amount of computing resources, and in the embodiment of the disclosure, by simplifying the first image and determining the target plane based on the simplified first image, the computing resources can be saved, and the speed of determining the target plane can be improved. In addition, in the embodiment of the present disclosure, by using a server-client (server-client) architecture, a complex computing process is moved to the server, and the server determines a target plane, so that the computing efficiency and the positioning accuracy can be improved, the occupation of computing resources of the user terminal can be reduced, and the hardware requirement of the user terminal can be reduced, so that the user terminal can focus on the delay problem, display the processing result of the server in time, and can implement higher accuracy by using the computing resources of the server.
In a possible implementation manner, the determining, according to the simplified first image, a mapping relationship between a first coordinate system and a screen coordinate system of the user terminal includes: extracting feature points of the simplified first image; in response to the number of matched feature points between any plane in the simplified first image and a preset plane template reaching a second preset threshold value, determining the plane as a target plane for displaying the virtual information; and determining a mapping relation between a first coordinate system and a screen coordinate system of the user terminal according to the position information of the target plane. In this implementation, the feature point may refer to a point where the image gray value changes drastically or a point where the curvature is large on the edge of the image (e.g., the intersection of two edges). In this implementation manner, the preset plane template may be a plane where the number of any one feature point in the target object reaches a sixth preset threshold, where the sixth preset threshold is greater than or equal to the second preset threshold. That is, the preset plane template may be any plane of the target object with sufficient feature points, so that the marker-less method may be adopted to determine the target plane. In this implementation manner, if the number of feature points matched between any plane in the simplified first image and a preset plane template reaches a second preset threshold, the plane may be determined to be the preset plane template, so that the plane may be determined to be a target plane for displaying the virtual information; if the number of the matched feature points between any plane in the simplified first image and a preset plane template does not reach a second preset threshold value, determining that the plane is not the preset plane template, and thus not determining the plane as a target plane for displaying the virtual information. In this implementation, the x-axis and the y-axis of the first coordinate system may be on the target plane, and the z-axis of the first coordinate system may be perpendicular to the target plane. Of course, those skilled in the art may also flexibly set the relationship between the coordinate axis of the first coordinate system and the target plane according to the requirements of the actual application scenario, which is not limited herein. In this implementation manner, according to the position information of the target plane in the screen coordinate system of the user terminal, a mapping relationship between a first coordinate system corresponding to the target plane and the screen coordinate system may be determined. In this implementation manner, feature point extraction is performed on the simplified first image, in response to that the number of feature points matched between any plane in the simplified first image and a preset plane template reaches a second preset threshold, the plane is determined as a target plane for displaying the virtual information, and a mapping relationship between a first coordinate system and a screen coordinate system of the user terminal is determined according to the position information of the target plane, so that the mapping relationship between the first coordinate system corresponding to the target plane for displaying the virtual information and the screen coordinate system of the user terminal can be quickly, accurately and conveniently determined, and thus the display processing process of the virtual information can be quickly, accurately and conveniently completed.
In a possible implementation manner, the server may return the mapping relationship and the virtual information to the user terminal. The user terminal may display the virtual information on the target plane in the live-action image displayed by the user terminal according to the mapping relationship. That is, in this implementation, the user terminal may present the virtual information on the target plane.
In another possible implementation manner, the server may return the mapping relationship, the virtual information, and the first coordinate of the virtual information in the first coordinate system to the user terminal. The user terminal may determine a second coordinate of the virtual information in the screen coordinate system according to a first coordinate of the virtual information in the first coordinate system and the mapping relationship, and display the virtual information at the second coordinate in the live-action image displayed by the user terminal. In this implementation, the virtual information may be presented based on a first coordinate system corresponding to the target plane, and a first coordinate of the virtual information in the first coordinate system may be on the target plane or may not be on the target plane. For example, the x-axis and y-axis of the first coordinate system are on the target plane, and the z-axis of the first coordinate system is perpendicular to the target plane. If the z coordinate of the first coordinate is 0, the virtual information can be displayed on the target plane; if the z-coordinate of the first coordinate is not 0, the virtual information may not be displayed on the target plane, that is, the virtual information may also be displayed on a plane other than the target plane.
Fig. 2 shows another flowchart of an information presentation method provided by the embodiment of the present disclosure. In one possible implementation, the information presentation method may be executed by a user terminal or other processing device. The User terminal may be a User Equipment (UE), a mobile device, a terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, or a wearable device. In some possible implementations, the information presentation method may be implemented by a processor calling computer readable instructions stored in a memory. As shown in fig. 2, the information presentation method includes steps S21 through S24.
In step S21, a virtual information obtaining request is generated according to a first image, where the virtual information obtaining request includes the first image, and the first image is determined according to a live-action image acquired by the user terminal for a real scene.
In step S22, the virtual information acquisition request is sent to the server.
In step S23, receiving the virtual information corresponding to the target object in the first image returned by the server, and the mapping relationship returned based on the simplified first image.
In step S24, the virtual information is displayed in the live-action image displayed on the user terminal according to the mapping relationship.
In the embodiment of the disclosure, the user terminal may acquire the live-action image through the image acquisition module to obtain the first image. In a possible implementation manner, the acquired live-action image may be used as the first image. In another possible implementation manner, the first image is obtained by performing compression processing on the live-action image. In this implementation manner, the user terminal may compress the acquired live-action image to obtain the first image. The virtual information acquisition request is generated according to the first image obtained after the compression processing is carried out on the basis of the live-action image, and the virtual information acquisition request is sent to the server, so that effective visual information can be sent to the server, and the bandwidth and the flow can be saved.
In this disclosure, the user terminal may generate a virtual information acquisition request according to the first image, and send the virtual information acquisition request to the server. The server may acquire the first image by receiving the virtual information acquisition request, so that visual information of a real scene faced by the user terminal may be acquired. In the embodiment of the present disclosure, the target object in the first image may be any type of object having virtual information to be presented in the first image. For example, in an application scenario of AR exhibition at a museum, the target object may be a history object, a painting, etc. in the museum. In this embodiment of the disclosure, the server may, in response to the virtual information acquisition request, acquire virtual information corresponding to a target object in the first image, perform simplification processing on the first image to obtain a simplified first image, determine, according to the simplified first image, a mapping relationship between a first coordinate system and a screen coordinate system of the user terminal, and return the mapping relationship and the virtual information to the user terminal.
In the embodiment of the disclosure, a virtual information acquisition request is generated according to a first image, where the virtual information acquisition request includes the first image, the first image is determined according to a live-action image acquired by a user terminal for a real scene, the virtual information acquisition request is sent to a server, virtual information corresponding to a target object in the first image returned by the server is received, and the virtual information is displayed in the live-action image displayed by the user terminal according to a mapping relationship returned by a simplified first image, so that a target plane for displaying the virtual information can be determined quickly and accurately based on the simplified first image, and a display processing process of the virtual information in the real scene can be completed quickly and accurately.
In a possible implementation manner, the mapping relationship represents a mapping relationship between a first coordinate system and a screen coordinate system of the user terminal, where the first coordinate system represents a coordinate system corresponding to a target plane for displaying the virtual information; after the sending of the virtual information acquisition request to the server, before the displaying of the virtual information in the live-action image displayed by the user terminal according to the mapping relationship, the method further includes: receiving a first coordinate of the virtual information returned by the server in the first coordinate system; the displaying the virtual information in the live-action image displayed by the user terminal according to the mapping relationship comprises: determining a second coordinate of the virtual information in the screen coordinate system according to a first coordinate of the virtual information in the first coordinate system and the mapping relation; and displaying the virtual information based on the second coordinate in the live-action image displayed by the user terminal. In this implementation, the virtual information is presented at the second coordinate in the live-action image displayed by the user terminal. The virtual information may be displayed based on a first coordinate system corresponding to the target plane, and a first coordinate of the virtual information in the first coordinate system may be on the target plane or may not be on the target plane. For example, the x-axis and y-axis of the first coordinate system are on the target plane, and the z-axis of the first coordinate system is perpendicular to the target plane. If the z coordinate of the first coordinate is 0, the virtual information can be displayed on the target plane; if the z-coordinate of the first coordinate is not 0, the virtual information may not be displayed on the target plane, that is, the virtual information may also be displayed on a plane other than the target plane. In this implementation manner, the first coordinate of the virtual information in the first coordinate system, which is returned by the server, is received by the user terminal, the second coordinate of the virtual information in the screen coordinate system is determined according to the first coordinate of the virtual information in the first coordinate system and the mapping relationship, and the virtual information is displayed based on the second coordinate in the live-action image displayed by the user terminal, so that the virtual information can be displayed more flexibly, and a richer display effect of the virtual information can be realized.
In another possible implementation manner, the user terminal may display the virtual information on the target plane in the live-action image displayed by the user terminal according to the mapping relationship. That is, in this implementation, the user terminal may present the virtual information on the target plane.
In a possible implementation manner, the number of the virtual information is at least one item, and any one item of the virtual information includes an icon; the displaying the virtual information in the live-action image displayed by the user terminal according to the mapping relationship comprises: and for any item of virtual information, displaying an icon of the virtual information in the live-action image displayed by the user terminal according to the mapping relation. As an example of this implementation, the virtual information corresponding to the target object may include virtual information corresponding to the entire target object. The virtual information corresponding to the whole of the target object may represent virtual information corresponding to the whole of the target object, but not virtual information corresponding to an object to be marked in the target object. As another example of this implementation, the virtual information corresponding to the target object may include virtual information corresponding to an object to be marked in the target object. In this example, in a case where the target object includes a plurality of objects to be marked, the virtual information corresponding to the target object may include a plurality of items of virtual information in one-to-one correspondence with the plurality of objects to be marked. For example, the target object is drawing a, and the virtual information corresponding to the target object may include virtual information corresponding to the whole drawing a, as well as virtual information corresponding to the bridge b, the house c, and the ship d in the drawing a. The virtual information corresponding to the whole drawing A can be used for introducing an author, a history background and the like of the drawing A, and the virtual information corresponding to the bridge b can be used for introducing a name, a related story and the like of the bridge b. As an example of this implementation manner, for any item of virtual information corresponding to the target object, the icon of the virtual information may include a preset icon. In this example, the different virtual information may include the same preset icon. As another example of this implementation, the icon of the virtual information may include an icon of a type corresponding to the virtual information. For example, if the object to be marked corresponding to the virtual information is a ship d, the type icon corresponding to the virtual information may be an icon of a ship pattern. As another example of this implementation, the icon of the virtual information may include a name of an object to be marked corresponding to the virtual object. For example, the virtual information corresponding to bridge b may include "XX bridge". In this implementation manner, for any item of virtual information, according to the mapping relationship, the icon of the virtual information is displayed in the live-action image displayed by the user terminal, so that the relevant information of the target object can be provided for the user on the premise that the user does not largely block the target object from being viewed.
As an example of this implementation, the virtual information further includes detailed information; after the icon showing the virtual information, the method further comprises: outputting detailed information of the virtual information in response to trigger information for an icon of the virtual information. In one example, where the virtual information includes detailed information, an icon of the virtual information may be highlighted. For example, an icon of the virtual information may be controlled to blink, or the icon of the virtual information may be controlled to emit light, or the like. By highlighting the icon of the virtual information in case the virtual information comprises detailed information, the user can be prompted to trigger (e.g. click) the icon of the virtual information, so that the detailed information of the virtual information can be further provided to the user. In this example, by outputting the detailed information of the virtual information in response to the trigger information of the icon for the virtual information, the detailed information can be presented in response to the user requirement, so that the user can be provided with richer related information of the target object without greatly influencing the user to view the target object.
Of course, in other examples, the detailed information of the virtual information may be displayed at the same time as the icon of the virtual information without triggering.
In one example, the detailed information of the virtual information includes visual information; the outputting the detailed information of the virtual information includes: and displaying the visual information of the virtual information. In this example, the visual information of the virtual information may include at least one of text, images, video, and the like. By responding to the triggering information of the icon of the virtual information, the visual information of the virtual information is displayed, so that richer visual information related to the target object can be provided for a user through the user terminal in response to the user requirement.
For example, after the presenting the visual information of the virtual information, the method further comprises: hiding the visual information of the virtual information in response to an icon for the virtual information or trigger information of the visual information of the virtual information. In this example, by hiding the visual information of the virtual information in response to the icon for the virtual information or the trigger information of the visual information of the virtual information, it is possible to reduce interference of the virtual information with the user's viewing of the target object in response to the user's demand.
In another example, the detailed information of the virtual information includes audio information; the outputting the detailed information of the virtual information includes: and playing the audio information of the virtual information. In this example, by playing the audio information of the virtual information in response to the trigger information of the icon for the virtual information, it is possible to provide the user with richer auditory information related to the target object through the user terminal in response to the user's demand.
For example, after the playing the audio information of the virtual information, the method further includes: and in response to the trigger information of the icon aiming at the virtual information, pausing or stopping playing the audio information of the virtual information. In this example, by pausing or stopping playing of the audio information of the virtual information in response to the trigger information for the icon of the virtual information, it is possible to reduce the interference of the audio information of the virtual information with the user in response to the user's demand.

As an example of this implementation, the virtual information further includes detailed information; after the icon showing the virtual information, the method further comprises: outputting detailed information of the virtual information in response to trigger information for an icon of the virtual information.
In one example, the detailed information of the virtual information includes visual information; the outputting the detailed information of the virtual information includes: and displaying the visual information of the virtual information.

The mobile phone generates a virtual information acquisition request according to the first image and sends the virtual information acquisition request to a server, wherein the virtual information acquisition request comprises the first image. And the server receives the virtual information acquisition request and responds to the virtual information acquisition request to extract the characteristic points of the first image. And the server determines that the target object in the first image is the drawing A according to the characteristic point of the first image, and acquires virtual information corresponding to the drawing A. And the server detects the objects of which the number of the characteristic points in the first image reaches a first preset threshold, and in response to the detection that the number of any characteristic point reaches the objects of the first preset threshold, matches the objects of which the number of the characteristic points reaches the first preset threshold with the objects to be marked in the drawing A. And the server side responds to the fact that the object with the number of the characteristic points reaching the first preset threshold value is not matched with the object to be marked in the drawing A, removes the object with the number of the characteristic points reaching the first preset threshold value from the first image, and obtains a simplified first image. And the server extracts the characteristic points of the simplified first image, and determines the plane as a target plane for displaying the virtual information in response to the fact that the number of the characteristic points matched between any plane in the simplified first image and a preset plane template reaches a second preset threshold value. The server side can determine a mapping relation between a first coordinate system corresponding to the target plane and a screen coordinate system of the user terminal according to the position information of the target plane, and returns the mapping relation, the virtual information and a first coordinate of the virtual information in the first coordinate system to the user. The mobile phone may determine a second coordinate of the virtual information in the screen coordinate system according to the first coordinate of the virtual information in the first coordinate system and the mapping relationship, and display an icon of the virtual information based on the second coordinate in the live-action image displayed by the user terminal. Fig. 4 is a schematic diagram illustrating an information displaying method according to an embodiment of the disclosure. In the example shown in fig. 4, a target object 3100 is included in the first image 3000, and the target object 3100 is a drawing a.

The mobile phone may output detailed information of the virtual information in response to trigger information of an icon for the virtual information. Fig. 5 shows another schematic diagram of an information presentation method provided by the embodiment of the present disclosure. As shown in fig. 5, in response to the trigger information for the icon 3121, detailed information 3122 corresponding to the object to be marked 3110 may be presented. As shown in fig. 5, in one example, in a case where detailed information of any one item of virtual information is presented, icons of other items of virtual information may be hidden to reduce interference with a user viewing a target object. The mobile phone can also respond to the icon aiming at the virtual information or the trigger information of the detailed information of the virtual information, and hide the detailed information of the virtual information. In one example, after hiding the detailed information of the virtual information, icons of the items of virtual information may be re-presented.
