Preferably, in step S12, the television screen closest to the center of the television wall is selected as the base screen.
Preferably, the method further comprises the step S10: numbering each television screen, establishing an initial set, and pre-storing the number of each television screen in the initial set; step S12 specifically includes: selecting a television screen as a basic screen, and deleting a number corresponding to the television screen from the initial set; step S14 specifically includes: combining the spliced screens to a basic screen to form a new basic screen, and deleting the serial numbers of the spliced screens from the initial set; step S16 specifically includes: it is determined whether there are any remaining numbers in the initial set.
Preferably, the method further comprises the step S3: presetting a plurality of television screen distribution modes and a plurality of file conversion modes to be played, wherein the file conversion modes to be played correspond to the television screen distribution modes one to one; in step S2, the file to be played is converted to obtain the playing object of each tv screen with reference to the file to be played conversion mode corresponding to the current distribution mode of the tv screen.
In the invention, the current distribution mode of the television screens is determined by acquiring the relative distance of all adjacent television screens on the television wall and according to the acquired relative distance values. Therefore, by introducing the relative distance, a clear reference standard is provided for judging the current distribution mode of the television screen, the latest current distribution mode of the television screen can be accurately obtained in real time when the television wall is changed, and a foundation is laid for changing the playing mode of the television screen according to the updating of the television wall.
The invention can quickly convert the file to be played according to the converted television wall shape, ensures the real-time connection of the front and back playing of each television screen, and ensures that the television wall can work normally in the conversion process.

Detailed Description
Referring to fig. 1, the method for converting pictures of a spliced video wall provided by the invention comprises the following steps.
And S11, acquiring the relative distance between all adjacent television screens on the television wall.
And S12, selecting a television screen as a basic screen.
And S13, judging whether the basic screen has a spliced screen which is adjacent to the basic screen and has a relative distance smaller than a preset distance threshold value.
In practical application, two edges of adjacent television screens close to each other are parallel to each other in any state of the television screens on the television wall. Therefore, the distance between the two edges of the adjacent television screens close to each other is the relative distance between the adjacent television screens.
And S14, if yes, combining the spliced screen to the basic screen to form a new basic screen, and then returning to the previous step.
And S15, if not, taking the basic screen as an independent screen.
S16, it is determined whether there is an independent tv screen which is not defined as an independent screen. The purpose of this step is to find television screens that are neither defined as base screens nor as spliced screens. Specifically, in this embodiment, numbers of the television screens may be numbered, an initial set is established, numbers of the television screens are pre-stored in the initial set, and numbers corresponding to the basic screen are deleted from the initial set after each step S12, and numbers of the obtained mosaic screens are deleted from the initial set after each step S13; step S16 determines whether there is an independent television screen that is not defined as an independent screen by determining whether there are any numbers remaining in the initial set.
S17, if yes, reselecting a television screen as a basic screen, and then returning to the step S13. If there are numbers remaining in the initial set, this indicates that there are still tv screens in the tv wall that are not defined as either base screens or mosaic screens.
And S18, if not, determining the current distribution mode of the television screen according to the state of each independent screen. Specifically, if the initial set is an empty set, this indicates that there are no separate television screens that are not defined as separate panels.
And in combination with the steps S11 to S18, determining the current distribution mode of the tv screens according to the obtained relative distance values by obtaining the relative distances between all adjacent tv screens on the tv wall. Therefore, by introducing the relative distance, a clear reference standard is provided for judging the current distribution mode of the television screen, the latest current distribution mode of the television screen can be accurately obtained in real time when the television wall is changed, and a foundation is laid for changing the playing mode of the television screen according to the updating of the television wall.
In step 12, the television screen closest to the center of the television wall is selected as the basic screen, so that the spliced screen can be searched in a mode of diffusing from the center to the periphery, and simultaneous searching in multiple directions can be realized, so that the working efficiency is improved.
S3: presetting a plurality of television screen distribution modes and a plurality of file conversion modes to be played, wherein the file conversion modes to be played correspond to the television screen distribution modes one to one.
And S2, converting the file to be played according to the current distribution mode of the television screens to obtain the playing object of each television screen, and each television screen obtains the corresponding playing object to play. Specifically, in this step, the file to be played is converted with reference to the file to be played conversion mode corresponding to the current distribution mode of the television screens, so as to obtain the playing object of each television screen.
Therefore, by setting the corresponding relation between the file conversion mode to be played and the television screen distribution mode, the file to be played can be quickly converted according to the converted television wall shape, the real-time connection of front and back playing of each television screen is ensured, and the television wall can still normally work in the conversion process. The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
