the cloud server sends a message to the second user to inquire whether to pay for watching;
if the inquiry result is yes, the second user pays the fee on the second mobile device, whether the fee is received or not is judged at the cloud service end, and if yes, the cloud service end issues an instruction to activate the digital content displayed by the corresponding display device.
3. The method for displaying digital content based on spatial anchor points according to claim 1, wherein after the cloud server issues an instruction to activate an article displayed by a corresponding display device according to the ID information corresponding to the display device, the method further comprises:
and judging whether the space distance between the second user and the current space anchor point exceeds a preset threshold value, if so, stopping displaying by the display equipment.
4. An apparatus for digital content presentation based on spatial anchor points, the apparatus comprising:
the second sending module is used for acquiring second image data for imaging a second physical world position and a space representation corresponding to the second image data captured by an image acquisition device in second mobile equipment based on second mobile equipment of a second user, and uploading the space representation corresponding to the second image to the cloud server;
the judging module is used for judging whether the second image data is matched with the stored first image data; the first image data is obtained by capturing a first physical world position through an image acquisition device in first mobile equipment based on the first mobile equipment of a first user;
the second processing module is used for returning a spatial anchor point with position information relative to the display equipment during matching, and the second mobile equipment of the second user receives the spatial anchor point sent by the cloud server; creating, by the first mobile device, a spatial representation of a first physical world location and a spatial anchor point based on the first image data, and sending, from the first mobile device to the cloud server, a gesture of the spatial representation and the spatial anchor point for cloud storage, the cloud server binding virtual content related to digital content with the spatial anchor point, the virtual content related to digital content including item information describing a displayed item and ID information of a display device displaying the item; the second mobile equipment acquires the ID information corresponding to the display equipment according to the received space anchor point and uploads the ID information to the cloud server; the cloud server side issues an instruction according to the ID information corresponding to the receiving display equipment so as to activate the digital content correspondingly displayed by the corresponding display equipment;
and when the digital content is not matched with the spatial anchor point, the second mobile equipment of the second user does not receive the spatial anchor point, and the digital content is not displayed by the display equipment.
5. An electronic device, comprising: one or more processors;
a memory;
one or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the one or more processors, the one or more programs configured to perform the method of any of claims 1-3.
6. A computer-readable storage medium, having stored thereon program code that can be invoked by a processor to perform the method according to any one of claims 1 to 3.
