If the user selects the "area a" option and the "area B" option, the holographic screens arranged in the "area a" option and the "area B" are required to play the play content setting option at the same time.
The setting options of the playing content comprise recommended content options and custom input options, wherein the recommended content options comprise but are not limited to preset publicity terms such as 'national immunity, crowdsourcing and consummation of city' and 'vaccination of new crown vaccine, building of great wall of immunity' and the like.

specifically, in this step, as shown in fig. 5, for the area a, the one-way time for the terminal to send the currently played content to the currently controlled holographic screen of the area a is t1-1, and the actual time for the terminal to send the currently played content to each of the currently controlled holographic screens is different because of different distances between different areas and the terminal, and in order to implement simultaneous playing of each of the currently controlled holographic screens, the currently played content cannot be played immediately after each of the currently controlled holographic screens receives the currently played content.
In this step, the actual time spent by each current hologram screen to be controlled to receive the current playing content is obtained.

specifically, as shown in FIG. 5, the one-way time for the terminal to transmit the currently played content to the current holographic screen to be controlled is t2-1, t3-1 and t4-1, respectively. Assuming that the longest time length among t1-1, t2-1, t3-1 and t4-1 is actually t4-1, in this step, the actual elapsed time with the longest time length is selected from the actual elapsed times, i.e., t4-1, and t4-1 is also referred to as the playing reference time.
Further, the play reference time means that when the terminal sends data at the same time point, all current to-be-controlled holographic screens receive the data sent by the terminal after the play reference time elapses.
Step S430: generating same-frequency playing time according to the playing reference time, and sending the same-frequency playing time to each current holographic screen to be controlled;
specifically, when the time consumed by all current to-be-controlled holographic screens for receiving the data sent by the terminal is known, each current to-be-controlled holographic screen can be simultaneously controlled according to the time, and further.

Specifically, in this step, the current to-be-controlled holographic screens are controlled to play the current playing content at the same-frequency playing time based on the same-frequency playing time, so that the problem that the current to-be-controlled holographic screens cannot be played simultaneously due to different consumed time for receiving data caused by different distances between each region and the terminal is solved. Therefore, the same-frequency playing is realized with high precision.
In another embodiment of the present invention, as shown in fig. 6 to 7, the generating the same-frequency playing time according to the playing reference time further includes:
step S431: acquiring a loss setting trigger instruction for starting transmission loss setting;
specifically, in this step, by obtaining the loss setting trigger instruction, it means that the user needs to set a custom transmission loss value. The user-defined transmission loss value is used for indicating the problem of time loss possibly caused by the performance of the terminal in the transmission process of the current playing content.
Step S432: generating a loss setting interface based on the loss setting triggering instruction, wherein a loss setting option and a reference setting option are displayed on the loss setting interface;
specifically, in this step, the loss setting interface is provided with setting guide, and the setting guide can guide the user to set the high efficiency and the rapidness in the process, so that the user experience can be improved.
Further, the setting guide, before being displayed on the wear setting interface, further comprises the following steps:
firstly, after the loss setting interface is generated, data transmission configuration data of a carrier of the loss setting interface is obtained.
Then, an intrinsic loss reference value is generated from the data transmission configuration data.
When the terminal is a mobile phone, the data transmission configuration data is a core control chip of the mobile phone, and a network data exchange technology supported by the current mobile phone and a data transmission speed which can be realized by the technology are calculated according to the core control chip.
After obtaining the data transmission speed, a person skilled in the art can generate an intrinsic loss reference value according to the data transmission speed, where the intrinsic loss reference value indicates an extra time required to be consumed by the current terminal in the signal transmission process under the current configuration.
Further, as shown in fig. 7, the reference setting option is the inherent loss reference value set in advance, that is, when the user sets on the loss setting interface, the inherent loss reference value can be seen, and the set reference selection is provided for the user through the inherent loss reference value.
On the other hand, the loss setting option provides a user with a possibility of self-defining setting, so that efficient and fast self-defining setting is achieved, for example, after the user knows the inherent loss reference value, but does not select the inherent loss reference value, but considers that the inherent loss reference value has a problem exceeding effective timeliness, for example, if the inherent loss reference value is set at 9, 2 and 2021, 6, 24 and the user sets the inherent loss reference value, then the inherent loss reference value may increase due to long-time use of the terminal, in this case, the user does not select the inherent loss reference value, but sets a self-defining value larger than the inherent loss reference value according to the loss setting option, so that more precise simultaneous play control is achieved, and the synchronous play precision is improved.
Step S433: obtaining a user-defined transmission loss value set according to the loss setting option and the reference setting option;
specifically, in this step, a user-defined transmission loss value is set by a user, that is, the user-defined transmission loss value in this step.
Step S434: and generating the same-frequency playing time according to the user-defined transmission loss value and the playing reference time.
Specifically, in this step, after the user-defined transmission loss value is obtained, and the playing reference time, the same-frequency playing time can be generated according to the user-defined transmission loss value and the playing reference time, so as to realize accurate and efficient synchronous playing control of a plurality of holographic screens in different areas.
In another embodiment of the present invention, in generating the same-frequency playing time according to the customized transmission loss value and the playing reference time, the same-frequency playing time is generated based on the following formula:
T＝α*ΔT+Φ；
wherein, T is the same frequency playing time, alpha is a fixed proportion value, delta T is the playing reference time, and phi is the user-defined transmission loss value.
Specifically, in this step, the fixed ratio α has a value of 3. As shown in fig. 5, when the play reference time Δ T is T-4, the one-way time for the terminal to send the current content to be played to the current hologram screen to be controlled for the first time is T-4. And then, the current holographic screen to be controlled sends feedback information to the terminal through a data communication module in the current holographic screen to be controlled, and the consumed time in the process is also t-4.
After the terminal acquires the feedback information sent by the current holographic screen to be controlled, the actual time consumed for the current holographic screen to be controlled to receive the current playing content can be acquired, at the moment, the terminal sends the same-frequency playing time to the current holographic screen to be controlled, the time t-4 is consumed in the process, and the total time spent from the current holographic screen to be controlled in the region D to receive the current playing content to the same-frequency playing time is 3 (t-4). Therefore, the fixed ratio value α has a value of 3.
Further, when the current to-be-controlled holographic screen of the area D farthest from the current to-be-controlled holographic screen has received the same-frequency playing time, the rest of the holographic screens in the current playing area have received the same-frequency playing time. At this time, the same-frequency playing time can be calculated by using the formula in addition to the preset custom transmission loss value phi, so that the simultaneous playing control of the current to-be-controlled holographic screen in the current playing area according to the same-frequency playing time is realized, and the efficient and accurate control is further realized.
In another embodiment of the present invention, as shown in fig. 8, after the controlling, according to the receiving success instruction, each of the current to-be-controlled holographic screens to simultaneously play the currently played content, the method further includes:
step S510: acquiring real-time display images formed after the current playing content is played by each current holographic screen to be controlled;
specifically, in this step, a real-time display image formed after the currently played content is played by each of the current to-be-controlled holographic screens is acquired based on an image acquisition device, and the image acquisition device is configured to match with each of the current to-be-controlled holographic screens and is used to acquire an image played by the current to-be-controlled holographic screen.
Step S520: generating a standard display image according to the current playing content;
specifically, in this step, after the current playing content is obtained, the standard display image may be generated in a simulated manner, where the standard display image is an image that is formed after the current playing content is displayed in a rational manner.
Step S530: judging whether the real-time display image is matched with the standard display image;
specifically, in this step, the effect of judging the display of each current to-be-controlled holographic screen is further achieved by judging whether the real-time display image is matched with the standard display image.
Step S540: if the real-time display images are judged to be the real-time display images, a playing effect display interface is generated and used for displaying the real-time display images.
Specifically, in this step, if it is determined that the real-time display image is matched with the standard display image, it is determined that the current display effect of the holographic screen to be controlled is better, that is, the current display effect can be displayed.
Furthermore, the images which are presented to the user and have good display effects are displayed on the premise that the display effects are judged better, and the user experience is improved.
In another embodiment of the present invention, as shown in fig. 9, after the determining whether the real-time display image matches the standard display image further includes:
step S551: if not, generating holographic screen fault information;
specifically, in this step, if the determination result is no, it is determined that the real-time display image is not matched with the standard display image, and at this time, a playback error is indicated.
Thus, the holographic screen failure information is generated. The holographic screen fault information indicates a corresponding holographic screen fault.
Step S552: and generating the fault reminding interface according to the holographic screen fault information, wherein the fault reminding interface is used for displaying the holographic screen fault information.
Specifically, in this step, the fault information of the holographic screen displayed through the fault prompting interface is realized by generating the fault prompting interface, so as to prompt a user to repair the relevant holographic screen.
In another embodiment of the present invention, as shown in fig. 10 to 11, the determining whether the real-time display image matches the standard display image specifically includes:

And considering that the real-time display image comprises a text image and a picture image, wherein the characteristic association relation comprises the text characteristic association relation and the picture characteristic association relation.
The text image is an image formed after the text content is displayed as an image. If the text content is "epidemic prevention and control, from my work", then, for the image formed by the text content of this type, the key image feature is the corner part in each preset font, such as the bending part of the upper left corner and the lower right corner of the "few" in "anti", and the part may have errors after being displayed, so the key image feature is preset.
In this embodiment, the text feature association relationship is an association relationship between the text image and a key image feature corresponding to the text image, and when the text image is detected, the key image feature corresponding to the text image can be identified through the text feature association relationship.
The picture image is picture content or an image formed after the picture and characters are displayed in a mixed mode. If the picture content is the content shown in fig. 11, the key image features of the image formed by the mixed display of the picture and the text are the preset five sense organs image features of the lion in fig. 11, the five sense organs image features include some arcs, and errors are easy to occur when the picture and text are displayed, so that the content including the arcs is preset as the key image features.
In this embodiment, the picture feature association relationship is an association relationship between the picture image and a key image feature corresponding to the picture image, and when the picture image is detected, the key image feature corresponding to the picture image can be identified through the picture feature association relationship.
Step S532: judging whether the key image features are contained in the standard image features preset in the standard display image;
specifically, in this step, after the key image feature is set, it may be determined whether the key image feature in the real-time display image is included in the standard display image by determining whether the key image feature is included in a standard image feature preset in the standard display image.
The standard image features are preset in the standard display image and used for being compared with key image features in the real-time display image, and whether the key image features are included in the preset standard image features in the standard display image or not is judged.
Step S533: if the key image features are contained in the standard image features, judging that the real-time display image is matched with the standard display image; and if the key image features are not contained in the standard image features, judging that the real-time display image is not matched with the standard display image.
Specifically, in this step, if it is determined that the key image feature is included in the standard image feature, it is determined that the real-time display image already displays content that is prone to error, and on the premise that the content that is prone to error is already displayed, the remaining simple content is inevitably free from error.
