The embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. For the structures, products and the like disclosed by the embodiments, the description is relatively simple because the structures, the products and the like correspond to the parts disclosed by the embodiments, and the relevant parts can be just described by referring to the method part.
The embodiment of the invention discloses an augmented reality display method, as shown in figure 1, comprising the following steps:
s101, receiving signal source identification information;
s102, associating the signal source identification information with the content information to generate associated information, wherein the associated information is used for representing the association relationship between the signal source identification information and the content information;
and S103, sending the content information and the associated information to the user.
The signal source includes an object that can emit a broadcast signal, the broadcast signal may include a visual signal, such as a visible light image, or may include a non-visual signal, such as an infrared image, and the user may receive the signal emitted by the signal source through an augmented reality display device worn by the user.
The signal emitted by the signal source comprises signal source identification information. Alternatively, the signal source may include an identification number, and the identification number may be a fixed number or a temporarily assigned number, and further, the identification number may have uniqueness or uniqueness within a specific range. The signal source identification information may carry an identification number of the signal source for distinguishing from other signal sources.
The embodiment of the present invention does not limit the manner of receiving or sending information, and may exemplarily include a mobile communication network, a wireless local area network, bluetooth, or other various optional technical solutions.
In S101, the signal source identification information may be received by capturing an image, acquiring a visible light image, an infrared image, or the like.
In S102, the content information may include content information locally generated or stored by the augmented reality display device, or may include content information received by the augmented reality display device and generated or stored by another device. And the augmented reality display device associates the received signal source identification information with the content information and generates associated information, wherein the associated information is used for representing the association relationship between the signal source identification information and the content information. Since the signal source identification information has uniqueness, the signal source identification information can be uniquely associated with the content information.
In S103, the content information and the associated information are sent to the user, and particularly, when a plurality of users exist in the area or the network and the plurality of users need to receive different content information, the associated information may indicate the content information that the users need to receive to the user, so as to avoid the users from receiving irrelevant content information.
The technical scheme disclosed by the embodiment of the invention can be used for pushing the specific content information to the user in a targeted manner, and the user is prevented from receiving and displaying a large amount of redundant content information irrelevant to the user.
In addition, the user also desires that specific content information be displayed at a corresponding position accurately when viewing the content information through the augmented reality display device. Generally, the display position of the content information can be obtained by means of completely depending on the operation of a processor, but is not accurate and reliable.
Optionally, before sending the content information to the user, the method may further include:
and S104, sending display setting information to the user, wherein the display setting information comprises display position information, and the display position information is used for indicating the display position of the content information.
For example, as shown in fig. 2, the guide may install a signal source on the top of a banner of the guide and transmit display setting information indicating a display position of content information, i.e., a virtual reality area, to the user. The tourist can see the content information displayed in the virtual reality area moving along with the tour guide through the augmented reality display device along with the travel of the tour guide, and the content information can comprise related information about the explanation of the tour guide to the scenic spot.
Optionally, S101 may further include:
s1011, receiving the signal source identification information, including receiving a plurality of signal source identification information, where the association information may be used to represent an association relationship between the plurality of signal source identification information and the content information.
For example, as shown in fig. 3, in a game played by multiple players, such as a chess or a card game, a plurality of fixed signal sources may be placed on a chess or card table, for example, one signal source is placed at each of four corners of the chess or card table. The display setting information is sent to the user, the display position of the content information can be indicated to be the chess and card table, and further, the display position can be in the area enclosed by the four signal sources. For table games, the position marking of content information needs higher precision, such as the position of a chessman, and the traditional calibration mode based on image recognition and background operation cannot realize real-time high-precision display. The technical scheme disclosed by the embodiment of the invention can be used for solving the complex situation, for example, two parties play table tennis with the assistance of an augmented reality display device, and the embodiment of the invention can also greatly reduce the calculation amount required by position calibration on the basis of ensuring the precision.
Illustratively, during a speech, a speaker can attach a patch-type signal source to 4 vertices of a rectangular white board, and establish a virtual information display area according to the positioning of four corners of the rectangular white board, and an augmented reality display device of an audience can display content information in the virtual information display area corresponding to the position of the white board according to received position information. Because of the quadrangular positioning, the positioning of the position during the display is more accurate, for example, when the speaker indicates the corresponding position in the virtual information display area with a marking tool, a laser pointer, a baton, or the like, there is no deviation in the position of the marking object in the field of view of the listener.
Optionally, S103 may further include:
s1031, receiving an authentication request sent by a user;
s1032, according to the authentication request, the content information and the associated information are sent to the user.
The disclosed content information without authority can be sent to each user without authentication. However, for non-public content information, it should be transmitted only to the user with access right, so the right assignment should be performed to the user, and the user authentication should be performed before transmitting the content information.
Optionally, the allocation mode of the access right is not limited in the present invention. In the embodiment of the invention, the host of the augmented reality display equipment receives an authentication request sent by a user, confirms the access authority of the user according to the received authentication request, and sends content information and associated information to the user for the user with the access authority passing the authentication, otherwise, does not send the content information and the associated information.
The technical scheme disclosed by the embodiment of the invention can complete the pushing of the content information of multiple users in an augmented reality scene, and can also perform static or dynamic calibration on the display position of the content information, so that the positions of the content information observed by different users at the same time can be accurately matched.
