Detailed Description
The following detailed description of the disclosed embodiments will be made in conjunction with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Before introducing the display control method of the special-shaped LED display screen provided by the present disclosure, a target application scenario related to each embodiment in the present disclosure is first introduced, where the target application scenario includes an electronic device, and the electronic device may be, for example, a Personal computer, a workstation, a notebook computer, a smart phone, a tablet computer, a smart television, a smart watch, a PDA (Personal Digital Assistant, chinese), and the like.
Fig. 1 is a flowchart illustrating a display control method of a special-shaped LED display screen according to an exemplary embodiment, which is applied to an electronic device, and as shown in fig. 1, the method includes:
in step 101, a picture to be played and special-shaped screen information of a special-shaped LED display screen are obtained.
Wherein the abnormal screen information includes: the number of the display surfaces, the connection relation of the display surfaces and the size of the display surfaces of the special-shaped LED display screen are determined.
For example, the special-shaped LED display screen is usually modified from a conventional LED display screen to a special display screen shape to adapt to the overall structure and environment of a building, for example, LED display screens with various shapes such as LED magic cube, LED letter screen, LED ddj table, etc. The special-shaped LED display screen in this embodiment generally refers to a polyhedron-shaped special-shaped LED display screen. After receiving the to-be-played picture sent by the sending card through the program playing control software on the electronic device, before adjusting the to-be-played picture to display on the special-shaped LED display screen, the special-shaped screen information of the special-shaped LED display screen is generally acquired first to adjust the to-be-played picture according to the special-shaped screen information, so that the to-be-played picture can be completely displayed on the special-shaped LED display screen.
The step of acquiring the special-shaped screen information specifically comprises the following steps: the electronic equipment acquires the CAD coordinate information of the special-shaped LED display screen, or the electronic equipment imports the stored CAD coordinate information of the special-shaped LED display screen; and acquiring the number of display surfaces, the connection relation of the display surfaces and the size of the display surfaces of the special-shaped LED display screen according to the CAD coordinate information.
In addition, in a normal situation, the electronic device is in communication connection with the sending card, and after the to-be-played picture is adjusted through the following steps 102 and 105, the adjusted to-be-played picture (playing plane picture) is sent to the receiving card, so that the adjusted to-be-played picture is displayed on the special-shaped LED display screen through the receiving card. Wherein, this receiving card is located the box of dysmorphism LED display screen.
In step 102, according to the special-shaped screen information and a preset special-shaped screen slicing strategy, based on the corresponding relationship between the picture to be played and each display surface in the special-shaped LED display screen, the picture to be played is sliced, and a slice picture of the special-shaped LED display screen is obtained.
For example, in a general case, the special-shaped LED display screen includes a plurality of display surfaces (for example, a square hexahedral LED display screen includes six display surfaces), and the size and connection relationship of the six display surfaces and each display surface are determined according to the special-shaped screen information; and then according to the corresponding relation between each display surface in the special-shaped LED display screen and the picture to be played, determining which display surface of each display surface the picture to be played needs to display, and slicing the picture to be played according to a preset special-shaped screen slicing strategy, so that the sliced picture to be played (namely the sliced picture) can be displayed in the display surface.
In step 103, the slice images are spliced according to a preset slice image splicing strategy to obtain a spliced plane image corresponding to the special-shaped LED display screen.
For example, after the slice of the special-shaped LED display screen is obtained in step 102, in order to facilitate the user to adjust the slice according to the special-shaped LED display screen, the user is usually enabled to adjust the slice in the display interface of the electronic device. Therefore, the slice images are spliced according to a preset slice image splicing strategy to obtain spliced plane images, and the spliced plane images correspond to the special-shaped LED display screen.
In step 104, display screen information of a display interface on the electronic device is obtained, and the tiled planar picture is adjusted according to the display screen information to obtain a planar picture to be played corresponding to the display interface.
Illustratively, the display screen information of the display interface includes the size of the display interface and a target display area in the display interface, and after the spliced planar picture is scaled in an equal proportion according to the display screen information, the planar picture to be played which can be played on the display interface is acquired.
In step 105, the to-be-played flat screen is played on the display interface.
Illustratively, after the planar picture to be played is obtained in the step 104, the planar picture to be played is played on the display interface, so that the user can adjust the position of each slice in the planar picture to be played after being scaled in equal proportion (which is equivalent to adjusting the position of each slice in the spliced planar picture) according to the playing effect on the display interface, so that the adjusted planar picture to be played can be better played on the display interface, that is, the playing effect of the picture to be played on the special-shaped LED display screen is adjusted.
Exemplarily, as shown in fig. 2, which is a schematic diagram of a display control method of the special-shaped LED display screen shown in fig. 1, the special-shaped LED display screen 210 is in a hexahedron shape and includes six display surfaces, and when the pictures of the to-be-played surfaces are sliced and spliced into the spliced planar picture shown by 220 according to the sizes and the connection relationships of the six display surfaces and the corresponding relationship between the image in the to-be-played picture and each display surface. It can be understood that, in order to facilitate the user to observe the playing effect of the to-be-played picture on the special-shaped LED display screen 210 in the program playing control software, the spliced flat screen 220 needs to be scaled to obtain the to-be-played flat screen shown in the display interface 230 on the electronic device.
Fig. 3 is a flow chart of a slicing processing method according to fig. 1, and as shown in fig. 3, the step 102 includes:
in step 1021, a preset number of display surfaces to be played are determined in the display surface according to the corresponding relationship between the picture to be played and each display surface in the special-shaped LED display screen and the special-shaped screen information.
For example, in a general situation, the to-be-played picture sent by the sending card includes images that need to be displayed on each to-be-played display surface in the special-shaped LED display screen, and the user needs to adjust the images included in the to-be-played picture to clearly and completely display the images on each to-be-played display surface of the special-shaped LED display screen. Therefore, first, the corresponding relationship between the picture to be played and each display surface in the special-shaped LED display screen needs to be determined according to the picture to be played and the special-shaped screen information obtained in the step 101 (that is, the image and the special-shaped screen information which are required to be displayed on each display surface in the special-shaped LED display screen are determined according to the picture to be played), and then the preset number of display surfaces to be played is determined in each display surface according to the corresponding relationship and the special-shaped screen information.
In step 1022, the to-be-played image is cut according to the to-be-played display surface, and a preset number of to-be-played planes are obtained.
In an example, after the display surface to be played is determined, the picture to be played is cut, so that the cut plane to be played is used for displaying on each display surface to be played respectively.
In step 1023, the plane to be played is sliced according to a preset special-shaped screen slicing strategy, and a slice picture of the special-shaped LED display screen is obtained.
Specifically, if the number of edges included in the nth to-be-played plane is m, according to a preset special-shaped screen slicing strategy, obtaining (m-2) slice pictures of the nth to-be-played plane, adding the slice pictures obtained after slicing the nth to-be-played plane, and obtaining the slice pictures of the special-shaped LED display screen, where m is greater than or equal to 3.
Illustratively, the cut picture to be played includes n planes to be played, each plane is an irregular m-polygon, and the preset slicing policy is to perform triangle slicing on the m-polygon. When m is larger than or equal to 3, for example, if one to-be-played plane of the n to-be-played planes is a pentagon, a reference point is determined in five points of the pentagon, the reference point is respectively connected with other points in the pentagon to obtain three triangular slice pictures, and the slice pictures sliced by each to-be-played plane are respectively obtained, so that the slice pictures of the special-shaped LED display screen can be obtained.
In addition, when m <3, for example, the plane to be played back is circular, it can be understood that the circular picture to be played back is still sliced into circular slices according to a preset slicing strategy.
For example, the nth plane to be played is sliced according to the above method, and if the shape of the nth plane to be played is a trapezoid, two slices can be obtained after the trapezoid is sliced. When the trapezoid and the two sliced pictures after the slicing process are represented by row-column position + pixel point, for example, the trapezoid is an image with 2 rows and 7 columns, and the pixel points in each row are 5, 3, 6, 7, 2, 8, and 9, which are stored as 5367289 and 5367289; and in the two slices after the slicing processing, the first slice can be divided into 2 rows and 3 columns, the pixel points of each row are 5, 3 and 6, and stored as 2 rows and 3 columns 536536, and the second slice can be divided into 2 rows and 4 columns, the pixel points of each row are 7, 2, 8 and 9, and stored as 2 rows and 4 columns 72897289.
Fig. 4 is a flowchart of a picture adjustment method according to fig. 1, and as shown in fig. 4, the step 104 includes:
in step 1041, display screen information of a display interface on the electronic device is obtained.
In step 1042, the shape and size of the stitched planar picture are determined;
in step 1043, according to the display screen information, the tiled flat screen is adjusted to the to-be-played flat screen of the display interface according to the perspective transformation rule.
Illustratively, the display screen information of the display interface includes a size of the display interface and a target display area in the display interface, a target proportion that needs to be scaled is determined according to the target display area and a size and a shape of the tiled planar picture, the target proportion is scaled for the tiled planar picture through a perspective transformation rule, and the tiled planar picture is adjusted to be a planar picture to be played.
The perspective transformation rule is that the spliced plane picture is projected to a new viewing plane (i.e. in the display interface), and a plane picture to be played, which has the same shape and a certain proportion with the spliced plane picture, is obtained on the new viewing plane. In the perspective transformation process, the matrix of the original image (i.e. the stitched planar picture) is usually multiplied by the transformation matrix to obtain the planar picture to be played.
In summary, the present invention provides a display control method for a special-shaped LED display screen, which is applied to an electronic device, and includes: acquiring a to-be-played picture and special-shaped screen information of a special-shaped LED display screen, wherein the special-shaped screen information comprises: the number of display surfaces, the connection relation of the display surfaces and the size of the display surfaces of the special-shaped LED display screen are determined; acquiring a slice picture of the special-shaped LED display screen based on the corresponding relation between a picture to be played and each display surface in the special-shaped LED display screen according to the special-shaped screen information and a preset special-shaped screen slice strategy; splicing the slice pictures according to a preset slice picture splicing strategy to obtain a spliced plane picture corresponding to the special-shaped LED display screen; acquiring display screen information of a display interface on the electronic equipment, and adjusting the spliced planar picture according to the display screen information to obtain a planar picture to be played corresponding to the display interface; and playing the plane picture to be played on the display interface.
