Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, which is a schematic diagram of an application of an LED display screen automatic intelligent parameter setting system in an embodiment, the system includes: the LED display screen comprises an LED display screen controller 200, an intelligent terminal 300 and a plurality of LED display pixel module units, wherein the LED display screen controller 200 is connected with the intelligent terminal 300 through a network, the LED display pixel module units are connected with the LED display screen controller 200, and the LED display pixel module units form a screen body of the LED display screen 100.
The special-shaped LED display screen is an LED display screen composed of non-simple matrixes, and referring to fig. 1, the middle of the LED display screen 100 is hexagonal, in order to fill the LED pixels into the space, the LED display pixel module unit can be of a rhombic structure, and the uniform distribution principle of the LED pixels is kept; the periphery is formed by fitting six semicircular arcs, each semicircular arc comprises a plurality of LED display pixel module units, display data are transmitted among the LED display pixel module units through high-speed network cables, and the LED display pixel module units can be divided into a plurality of groups to be connected into the LED display controller 200 for parallel display, so that the display quality is improved. Each LED display pixel module unit is supported by a structural frame (namely a box body), and LED pixels are uniformly distributed on the display surface. Each LED display pixel module unit comprises a control receiving card (namely a sub-controller) and a plurality of LED driving and power supplies, data are transmitted in series through the receiving and sending cards, the number of the LED pixels of the special-shaped LED display pixel module units is different and is distributed according to the special-shaped shape, and the size and the shape of each block depend on the production and the installation convenience.
As shown in fig. 2, an automatic intelligent parameter setting method for an LED display screen is provided, which includes the following steps:
The LED display pixel module unit is composed of a plurality of LED pixel modules, and each LED pixel module is composed of a plurality of LED pixels. The parameter setting of the conventional LED display pixel module unit is performed by using the pixel module as a minimum unit. In the present application, the LED display pixel module unit is set as a minimum unit, and generally, the LED display pixel module unit includes a plurality of LED pixel modules, and the LED display pixel module unit may also be referred to as a "box" in the industry. Each LED display pixel module unit corresponds to a sub-controller which is a data receiving control card. The LED display pixel module unit comprises a data input interface and a data output interface, and the LED display pixel module units are connected to the LED display screen controller through wires. The LED display screen body is formed by the LED display pixel module units, and the LED display pixel module units can be connected at will and installed according to any shape.
The LED display screen controller is connected with the LED display pixel module unit, and the LED display screen controller sends a control signal to the LED display pixel module unit to control the lightening of the LED pixels. The control signal is a coordinate signal, one coordinate for each LED pixel. For example, suppose that there are n pixels in the LED display pixel module unit, the n pixels all correspond to a coordinate at the controller end, the control signal is composed of n data, each data corresponds to a coordinate, and generally 1 indicates on, and 0 indicates off. The one-by-one lighting is to control one LED pixel to be lighted at a time, and the others are extinguished, for example, (0,1,0, … …, 0) to represent the lighting of the corresponding coordinate 2. For the controller end of the display screen, each coordinate corresponds to one LED pixel, but it is unknown that each coordinate specifically corresponds to which LED pixel in the LED display pixel module unit, so that it is necessary to identify which LED pixel in the LED display pixel module unit corresponds to, that is, identify the relative coordinate of the LED pixel in the LED display pixel module unit, thereby knowing the corresponding relationship between the control signal and the LED pixel.
And 204, when the LED pixels in the LED display pixel module unit are lightened one by one, scanning the LED display pixel module unit through the intelligent terminal, reading the relative coordinates of the lightened LED pixels in the LED display pixel module unit, recording the mapping relation between each control signal and the relative coordinates of the corresponding LED pixels, and storing the mapping relation into the sub-controllers corresponding to the LED display pixel module unit.
When the LED display screen controller controls the LED display pixel module unit to light one LED pixel at a time, the LED display pixel module unit is scanned through the intelligent terminal, and the relative coordinates of the lighted LED pixel in the LED display pixel module unit are recorded. The relative coordinates refer to the positions of the LED pixels in the LED display pixel module unit. The LED pixels corresponding to different control signals are different, so that after the relative coordinates of the LED pixels are read, the relative coordinates of the LED pixels and the control signals are stored in the branch controllers in a correlated mode, and the subsequent branch controllers can know which LED pixel is controlled to be turned on when receiving the control signals. The establishment of the mapping relation is part of intelligent parameter setting of the LED display screen. The LED display pixel module unit in any shape can be set by adopting the method, so that the applicability is wide, and time and labor are saved.
In order to distinguish different LED display pixel module units, each LED display pixel module unit needs to be named, and the naming is generally in the form of a number, for example, 001,002, 003, and the like, and may also be named in other manners, which is not limited herein. In order to enable the intelligent terminal to recognize the LED display pixel module unit, an identification code capable of being scanned and recognized is generated. The identification code is used for identifying the name of the LED display module unit. The identification code may be implemented by a two-dimensional code, a barcode, a digital code, a pulse, or the like, or may be implemented by other methods, for example, by alphanumeric, color combination, smart code, or the like, which is not limited herein.
And 208, controlling each LED display pixel module unit to display the identification code at a preset position by the LED display screen controller.
After a plurality of LED display pixel module units are spliced into the LED display screen, namely after the LED display screen is installed, each LED display pixel module unit is controlled to display the identification code, and the preset position can be the middle position of each LED display pixel module.
And 210, identifying the identification codes through the intelligent terminal, and scanning to determine the relative position relation between the LED display pixel module units.
The intelligent terminal identifies identification codes in the LED display pixel module units of the whole display screen, and scans and determines the relative position relation between the LED display pixel module units based on the identified names. For example, a total of 100 LED display pixel module units identify the relative position relationship between the adjacent LED display pixel module units, and assume that the identified unit named 001 and the unit named 020 are adjacent to each other, and determine the relative position relationship between the two units. The determination of the relative positional relationship may be calculated by setting a reference point, and in each LED pixel module unit, the relative positional relationship between the reference points is calculated to determine the relative positional relationship between the two LED pixel module units.
And 212, the LED display screen controller acquires the installation angle of each LED display pixel module unit.
The installation angle is actually the rotation angle of the LED display pixel module unit. Because each LED display pixel module unit may not be completely spliced in the horizontal direction during installation, but spliced by rotating a certain angle, in order to determine a data stream segment to be subsequently displayed, the installation angle needs to be calculated, and the acquisition according to the angle may be directly through manual input, for example, for installation design, each installation angle is known, so that the installation angle can be directly acquired. Of course, it is also possible that the installation angle is not designed at the beginning, and it needs to be calculated at this time, and the LED display pixel module unit can be scanned by the intelligent terminal to determine the included angle between the LED display pixel module unit and the horizontal direction as the installation angle.
And 214, determining a display data stream segment corresponding to each LED display pixel module unit by the LED display screen controller according to the relative position relation among the LED display pixel module units and the installation angle of each LED display pixel module unit.
In order to enable the subsequent video pictures to meet the visual requirements of people when being projected onto the LED display screen, namely, the pictures are required to be continuous and non-deformed, the corresponding display data stream segments are required to be set according to the relative position of the display screen where the LED display pixel module unit is located. The display data stream segment is used to indicate which part of the picture data is to be cut. For an LED display screen, the size of a projection image corresponding to the LED display screen is determined, for example, a picture corresponding to a 2048X1280 size, for the projection image, the projection image is composed of 2048X1280 pixels, each pixel corresponds to a position identifier in the image, a display data stream segment may be represented by the position identifier of the pixel, and which position identifier in the image corresponds to each LED pixel in the LED display pixel module unit is determined, so as to determine the display data stream segment corresponding to the LED display pixel module unit, where the display data stream segment includes: and the positions corresponding to the LED pixels are identified.
The original image projected to the LED display screen is a regular rectangular image, and since the irregular screen is irregular, the regular rectangular image needs to be mapped to the irregular screen, and the mapping process is actually an intercepting process, for example, if the LED display screen is a circle, an area corresponding to the circle needs to be intercepted from the rectangular image and mapped to the LED display screen, and other parts not intercepted are not displayed. Because the LED display screen is formed by splicing a plurality of LED display pixel module units, a display data stream segment corresponding to each LED display pixel module unit needs to be set.
And step 216, the LED display screen controller stores the display data stream segments corresponding to each LED display pixel module unit into the corresponding sub-controllers to complete the setting of the LED display screen parameters.
The method comprises the steps that a display data stream segment corresponding to each LED display pixel module unit is determined and then recorded into a corresponding sub-controller, and therefore, subsequently, the sub-controller receives the transmitted data stream and knows which part is intercepted to display, all the data streams are received in the actual receiving process of each sub-controller, and after the display data stream segment is known, all the data streams are intercepted and displayed.
In the above-mentioned embodiment, need not carry out complicated planning design to LED display pixel module unit at the beginning of the development, only need adopt intelligent terminal just can realize carrying out the automation setting to the parameter of dysmorphism screen after production, this greatly reduced the setting degree of difficulty of dysmorphism screen, reduced the application threshold, widened the application space of LED display screen, this mode is applicable to any dysmorphism screen, includes: discontinuous distribution block display, sector display, irregular cambered surface screen display, spherical surface screen display, double cambered surface annular belt display, hollow display of the surface of the artistic font body with font strokes and the like, the application market of the LED display screen is expanded, and more personalized play spaces are provided for the personalized design of designers.
In one embodiment, before the scanning, by the intelligent terminal, the LED display pixel module unit when the LED pixels in the LED display pixel module unit are turned on one by one, reading the relative coordinates of the turned-on LED pixels in the LED display pixel module unit, recording the mapping relationship between each control signal and the relative coordinates of the corresponding LED pixels, and storing the mapping relationship in the sub-controller corresponding to the LED display pixel module unit, the method further includes: when all the LED pixels in the LED display pixel module unit are controlled to be lightened, scanning through the intelligent terminal to obtain the edge outline of the LED display pixel module unit; establishing a grid template according to the edge profile and the LED pixel interval;
when lightening the LED pixel in the LED display pixel module unit one by one, scan the LED display pixel module unit through the intelligent terminal, read the relative coordinate of the LED pixel of lightening in the LED display pixel module unit, include: and reading the positions of the lighted LED pixels in the grid template, and determining the relative coordinates of the lighted LED pixels in the LED display pixel module unit.
In order to accurately read the relative coordinates of the lighted LED pixels in the LED pixel module unit, firstly, a grid template is established, and an area corresponding to the grid template needs to be larger than the LED pixel module unit, so that the LED pixels in the LED pixel module unit are all displayed in the grid template. Therefore, the size of the grid template can be established according to the edge outline of the identified LED pixel module unit, and then the size of the grid is established according to the LED pixel interval, so that the LED pixel interval is multiple of the grid size, and each LED pixel can be positioned on the intersection point of the grid. When the lighted LED pixels are scanned through the intelligent terminal subsequently, the positions of the lighted LED pixels in the grid template only need to be recorded, and therefore the relative coordinates of the lighted LED pixels in the LED display pixel module unit are determined.
In one embodiment, the creating a grid template according to the edge profile and the LED pixel pitch comprises: determining the edge of the outermost periphery according to the edge outline, and determining a rectangular area according to the edge of the outermost periphery; and establishing a grid template according to the LED pixel distance and the size of the rectangular area of the intelligent terminal, so that each LED pixel is positioned on the intersection point of the grid.
Referring to fig. 3, the intelligent terminal 300 scans the entire outline of the fully-lit LED display pixel module unit 101. Referring to fig. 4, after the intelligent terminal 300 scans the entire outline of the fully-lit LED display pixel module unit 101, a grid template 301 is generated on the screen of the intelligent terminal 300 according to the pixel distribution of the LED display pixel module unit 101. The grid templating pixels are arranged in the matrix of the LED pixels with the special-shaped outline actual modeling structure, which is beneficial to undistorted restoration display of images, uniform matrix distribution of the LED pixels, accurate and unique pixel mapping and no rotation calculation coordinate difference. Grid templated pixel placement requires a physical pixel coordinate matrix, i.e., a grid templated arrangement.
In one embodiment, the identifying code is identified through the intelligent terminal, and the relative position relationship between the LED display pixel module units is determined, wherein the identifying code is identified through the intelligent terminal, and the name corresponding to each LED display pixel module unit is obtained; based on the naming, the relative position relationship between the LED display pixel module units forming the LED display screen is obtained through scanning.
Wherein, in order to make intelligent terminal can discern the relative position relation between the LED display pixel module unit, need demonstrate the identification code that LED display pixel module unit corresponds, intelligent terminal just can distinguish different LED display pixel module units like this, records the relative position relation between each LED display pixel module unit.
In one embodiment, the scanning to obtain the relative position relationship between the LED display pixel module units forming the LED display screen includes: respectively scanning and acquiring relative position relations of a plurality of LED pixel module units adjacent around relative to the reference by taking each LED display pixel module unit as the reference; and determining the relative position relationship among the LED display pixel module units forming the LED display screen according to the relative position relationship among the adjacent LED display pixel module units.
In order to obtain the relative position relationship between the LED display pixel modules, each LED display pixel module unit is taken as a reference, and the relative position relationship between a plurality of LED pixel module units adjacent to the periphery and the reference is obtained through scanning. For example, 3X3 matrix arrangement can be adopted for shooting, each LED display pixel module unit displays an identification code, relative coordinates of eight LED display units, namely, upper, lower, left, right, upper left, lower left, upper right and lower right, are determined by taking the middle unit as a reference, and then 3X3 scanning is repeated by taking the LED display units as centers one by one until all the LED display units are positioned, and the whole screen setting is completed. In fig. 5, the LED display pixel module unit 302 is used as a center for scanning and positioning, in fig. 6, the LED display pixel module unit 303 is used as a center for scanning and positioning, and in fig. 7, the LED display pixel module unit 304 is used as a center for scanning and positioning.
In one embodiment, the obtaining the installation angle of each LED display pixel module unit includes: acquiring a first angle formed by the grid template and the horizontal direction of the screen of the intelligent terminal; acquiring a second angle between the horizontal direction of the screen of the intelligent terminal and the actual horizontal direction; and superposing the first angle and the second angle to obtain the installation angle of each LED display pixel module unit.
Referring to fig. 8, the LED display pixel module unit 101 of the irregular LED display 100 is usually installed non-horizontally, and has an angle with the horizontal direction, so that in order to display the display image conforming to the visual characteristics of human eyes, that is, the display image is used to the horizontal direction, the correction needs to be performed, and the correction is performed by rotating the same angle in the opposite direction. In the figure, alpha is an included angle between the intelligent terminal 300 and a horizontal plane, and beta is a rotation angle of the grid template 301 generated according to the shot LED display pixel module unit and the intelligent terminal in the horizontal direction, and the rotation angle can be obtained through a relative coordinate of the grid template. Because the horizontal direction of the intelligent terminal can not be kept during intelligent setting, the rotation angle of the LED display unit can be more accurate by introducing the alpha angle, and therefore the video image can be better and completely restored. The actual deflection angle is the superposition of the angle alpha and the angle beta. In some embodiments, the α angle may be obtained by a tilt sensor inside the smart terminal 300.
In one embodiment, the determining, by the LED display screen controller, the display data stream segment corresponding to each LED display pixel module unit according to the relative position relationship between the LED display pixel module units and the installation angle of each LED display pixel module unit includes: determining a data stream segment corresponding to a sub-controller of each LED display pixel module unit according to the relative position relationship among the LED display pixel module units, wherein each sub-controller corresponds to a sub-control area; rotating the relative coordinates of each LED pixel in the sub-control area according to the installation angle to obtain the relative coordinates of each rotated LED pixel in the sub-control area; and determining a display data stream segment according to the relative coordinates of the rotated LED pixels in the sub-control area, wherein the display data stream segment is a part of a data stream segment corresponding to the sub-controller.
Each sub-controller corresponds to a sub-control area, the sub-control area is larger than the area corresponding to the LED display pixel module unit, and each LED pixel can also correspond to the coordinate in the sub-control area after rotation is facilitated. As shown in fig. 9A, which is a schematic diagram of a sub-control area in an embodiment, a rectangular area in the diagram is the sub-control area, a semicircular area is an area corresponding to the LED display pixel module unit in the sub-control area, and it is assumed that the semicircular LED display pixel module unit is rotated by 90 degrees when actually installed, and as shown in fig. 9B, which is a schematic diagram after being rotated by 90 degrees clockwise, it is obvious that relative coordinates of each LED pixel in the sub-control area after being rotated change, and a display data stream segment is determined according to the relative coordinates of each LED pixel in the sub-control area after being rotated.
