Preferably, panel confirms that module is used for the phase of close to each other two seamed edge according to the adjacent TV screen of each two Value of adjusting the distance determines panel assembled state.
Preferably, each locator is installed in the center of TV screen.
Preferably, reference object is arranged on the center of framework.
Preferably, locator is used to detect the vector value between reference object.
Preferably, in addition to panel selecting module and drive control module, a variety of panels are preset with panel selecting module Pattern, and can a kind of panel pattern of artificial selection be target panel;Drive control module connects panel selecting module and each respectively TV screen, for driving each TV screen to slide according to target panel.
In the present invention, coordinate setting module is by obtaining each TV screen when prelocalization and drawing in plane coordinates TV screen Distribution map, it is ensured that the TV screen distribution map in plane coordinates is consistent with the actual distribution situation that framework on TV shields, so as to protect Panel is demonstrate,proved and has confirmed that module determines the accurate of plane combination state according to panel distribution map.
In the present invention, video conversion module carries out parsing to video to be played according to panel assembled state and generates each TV The played file of screen.In this way, the TV screen combined state by combining each display screen, by the playing task of each display screen point Its TV screen included is cut, both ensure that the normal work of TV screen, in turn ensure that broadcasting for multiple TV screens on each display screen Put splicing.So as to advantageously ensure that on video wall, video playback file can weigh immediately with the change of TV screen assembled state New distribution, ensures the flexibility of video wall work.
Brief description of the drawings
Fig. 1 is a kind of video wall play system structure chart based on coordinate analysis proposed by the present invention.
Embodiment
Reference picture 1, a kind of video wall play system based on coordinate analysis proposed by the present invention, including:Framework, coordinate are fixed Position module, panel confirm module, video conversion module, panel selecting module and drive control module.
Framework, multiple TV screens, which are slidably mounted on framework, to be used to form video wall.
Coordinate setting module, its internal preset have plane coordinates.Coordinate setting module is connected with each TV screen, for obtaining Each TV screen is taken when prelocalization and the drafting TV screen distribution map in plane coordinates.Specifically, coordinate setting module includes:Installation The reference object of fixed position and the locator on each TV screen on framework.Locator is used to detect and reference Relative position between target is vector value, and the shape of each TV screen is pre-stored in coordinate setting module, and locator is fixed On TV screen.By the relative position of each locator and the TV screen installed is fixed, so, positioned In the case of device position, the installation site of TV screen can determine.Again because each locator is using same reference object as reference Positioned oneself, and the position of the reference object is stable, so, the relative position of each locator is stable.This embodiment party In formula, coordinate setting module be used for according to the testing result of locator and the installation site of locator in plane coordinates to each TV screen models to form TV screen distribution map.Because locator is relative with the TV screen at place stable, each locator is with reference to same Reference object, so, it is ensured that the TV screen distribution map in plane coordinates is consistent with the actual distribution situation that framework on TV shields. In present embodiment, each locator is installed in the center of TV screen, and reference object is arranged on the center of framework, with Just the producing efficiency of TV screen distribution map is improved.
Panel confirms module, is connected with coordinate setting module, for determining panel assembled state according to TV screen distribution map, Panel assembled state includes the display screen quantity after combination, the TV screen that each display screen includes and its ranking.Specifically, actual should In, each TV screen on video wall typically uses the motion mode of parallel sliding, so, the distance of adjacent TV screen can lead to The distance for crossing close to each other and parallel two seamed edge for calculating two TV screens is assessed.In present embodiment, panel is true Recognize module to be used to determine that panel combines according to the relative distance value of close to each other two seamed edge of the adjacent TV screen of each two The concrete mode of state is:Relative distance value and default distance threshold are contrasted, if relative distance value be less than or Equal to distance threshold, then judge that the two TV screens combine;Otherwise judge that two TV screens are separate.When it is implemented, away from 0 can be used from threshold value;If TV screen is connected by the way of being mutually embedded in, relative distance value is negative.
Video conversion module, panel is connected respectively and confirms module and each TV screen, for according to panel assembled state pair Video to be played carries out the played file that parsing generates each TV screen.Specifically, video conversion module confirms video to be played With the corresponding relation of each display screen.For example, if video to be played only had one, the multiple display of Video Quality Metric file driving Screen plays out to same video to be played.Because the TV screen combined situation of each display screen is different, so, Video Quality Metric text Part needs first to handle video to be played, the instant played file of each display screen is obtained, then according to display screen TV screen combined situation the played file that segmentation obtains each TV screen is carried out to instant played file.
If video to be played has multiple, Video Quality Metric file determines pair of each display screen and each video to be played first It should be related to, and drive video to be played corresponding to each display screen broadcasting.Because the TV screen combined situation of each display screen is different, institute So that Video Quality Metric file needs first to handle video to be played, obtains the instant played file of each display screen, so Carry out the played file that segmentation obtains each TV screen to instant played file according to the TV screen combined situation of display screen afterwards.
Played file corresponding to TV screen acquisition plays out.
Be preset with a variety of panel patterns in panel selecting module, and can a kind of panel pattern of artificial selection be target panel. Specifically, panel selecting module can use touch screen, so as to the displaying and selection of panel pattern.
Drive control module connects panel selecting module and each TV screen respectively, for driving each TV according to target panel Screen slides.
In present embodiment, module and panel selecting module are confirmed by panel, panel is confirmed and panel selective discrimination Come, advantageously ensure that the final panel that obtains confirms the accurate of result, so as to ensure the reliable and stable of video wall work.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto, Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
