The display information comprises display priority and display content displayed in a video or picture form. It should be noted that the display priority is divided into three levels: high priority, medium priority and low priority, in this embodiment, most of the presentation information is low priority. The high-priority display information has the highest importance degree and the largest required display area, and the low-priority display information has the lowest importance degree and the smallest required display area.
S200: and calculating to generate the display information quantity.
Specifically, the number of the display information under the same display priority is calculated at first, and the number of the display information is generated, so that each display priority corresponds to one display information number. And each display priority is correspondingly preset with a priority information quantity, the results corresponding to the corresponding display priorities can be obtained by multiplying the display information quantity and the corresponding priority information quantity, and the results corresponding to the three display priorities are added to obtain the display information quantity. The priority information quantity is preset with different numerical values according to different display priorities, and the priority information quantity corresponding to the high priority is the largest, and the priority information quantity corresponding to the low priority is the smallest.

. If the number of projectors in a certain multi-projection system is n, the corresponding display information amount threshold is D × n.
If the display information amount is less than or equal to the preset display information amount threshold, it is indicated that all the display information can be displayed at one time, at this time, only one display information list is generated, the display information list includes all the display information, and then, the process jumps to S500; if the display information amount is larger than the preset display information amount threshold, it indicates that the display information amount is too large and needs to be displayed in batches, and at this time, the process jumps to S400 to generate a plurality of display information lists.

Specifically, a plurality of preset empty display information lists are generated, the number of the display information lists is equal to the number M of turns, and the display information lists correspond to the turn numbers one to one, wherein the turn numbers are 1, 2, … … and M, and are used for representing each turn.
After generating an empty display information list, taking the display priority as a cycle characteristic, under the same display priority, dividing the number x of display information corresponding to the display priority by the total number M of turns, and generating a quotient of the average number x1 of the display priority,
the generated remainder is the random presentation number x2 of the presentation priority,
. Sequentially selecting x1 pieces of display information from all the display information corresponding to the display priority, respectively adding the display information into each display information list, after the distribution of x1 × M pieces of display information is completed, judging whether the random display number x2 is greater than 0, if the random display number x2 is greater than 0, randomly generating x2 turn numbers within the range of the turn total number M, wherein the randomly generated turn numbers correspond to the rest x2 pieces of display information one by one, and finally distributing the rest x2 pieces of display information to the display information list represented by the corresponding turn numbers; if the random presentation number x2 is equal to 0, then go directly to S403.
For example, if the total number of rounds M =3 and the number of pieces of presentation information corresponding to a low priority x =11, the average number of presentations generating a low priority x1=3 and the random number of presentations x2=2 are calculated. Therefore, 3 pieces of presentation information of low priority are assigned to each presentation information list, and the remaining 2 pieces of presentation information are randomly assigned to the 3 presentation information lists, each of which is randomly assigned 1 piece of presentation information at most.
S403: and generating display time according to the display information list.

After the processing is completed for all the presentation information lists, it jumps to S600.
S600: and judging whether the special display information list is empty or not.
Specifically, the special display information lists are used as the circulation feature, whether all the special display information lists are empty or not is sequentially judged, and if the special display information lists in the current circulation are empty, the step is skipped to S800 to directly allocate projector numbers to the display information lists; if the special display information list in the current cycle is not empty, the process jumps to S700.
S700: and distributing projector numbers for the display information in the special display information list.
In the current multi-projection system, each projector has a projector number, and each projector can project a standard picture according to a presentation model with a length-width ratio of 1: 1. In addition, it is necessary to supplement that the display information further includes a display size, and the display size is a specific length and a specific width of the display content.

S800: and distributing projector numbers for the display information in the display information list.
Specifically, in a certain display information list, the display priority is used as a circulation feature, and for the same display priority, the length and the width of the original display model are respectively enlarged according to the multiple relation k corresponding to the display priority in S700, so that the display model is updated. And then, carrying out image recognition on the display content, recognizing a key part in the display content, intercepting the display content with the size equal to that of the display model by taking the key part of the display content as a center according to the updated display model, and updating the display content. Distributing the display information according to the multiple relation k
And the number of each projector is bound with the display information corresponding to the current display content.
