All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method considers that the existing control method of the spliced screen group is only suitable for the spliced screen group arranged regularly, and the display requirements of the spliced screen group in other arrangement modes are difficult to meet, so that the applicability of the mode is poor; and the windowing mode in the mode is difficult to meet the requirement of a user for windowing across screens at any position. The embodiment of the invention provides a method, a device and a server for controlling a spliced screen group, and the technology can be applied to scenes for displaying and controlling the spliced screen group in various arrangement modes, in particular scenes for displaying and controlling the spliced screen group in irregular arrangement.
In order to facilitate understanding of the embodiment of the present invention, a detailed description is first provided for a control method of a tiled screen group disclosed in the embodiment of the present invention, as shown in fig. 1, the method includes the following specific steps:
step S102, acquiring the position coordinates and the screen size of each screen in the spliced screen group input by a user; wherein, this concatenation screen group contains two at least screens.
The screen may be a Light Emitting Diode (LED) display screen, which is usually a flat panel television screen, that is, a device composed of small LED module panels and used for displaying various information such as text, images, and videos; the LED display screen usually integrates the microelectronic technology, the computer technology and the information processing, and has the advantages of bright color, wide dynamic range, high brightness, long service life, stable and reliable work and the like.
The spliced screen group comprises at least two screens, and the screens can be arranged in any mode according to user requirements, such as a straight line type, an angle type, an oblique line type and the like. The user can input the position coordinates and the screen size of each screen according to the arrangement mode of the screens in the spliced screen group and the size of each screen. During specific implementation, a user can manually input the position coordinates and the screen size of each screen in the upper computer through a preset user interface, wherein the screen is usually rectangular, the position coordinates can include four vertex coordinates of the rectangle corresponding to each screen, and the position coordinates can also only include coordinates of the upper left corner of each screen (equivalent to the coordinates of the upper left corner) for simplifying user calculation; the screen size may include the height and width of the screen.
And step S104, obtaining the size of the maximum rectangular area corresponding to the spliced screen group according to the position coordinate and the screen size of each screen.
Because each screen is rectangular, the size of the maximum rectangular area corresponding to the spliced screen group can be calculated according to the position coordinate and the screen size of each screen in the spliced screen group, and the size can include the width and the height of the maximum rectangular area. In specific implementation, the size of the maximum rectangular area can be obtained according to the position coordinate of the screen at the upper left corner and the position coordinate of the screen at the lower right corner in the spliced screen group.
And S106, determining the display position of the spliced screen group based on the size of the preset display area and the size of the maximum rectangular area so as to control the screen in the display position.
The size of the preset display area may be set according to the size of the upper computer, or may be set according to a user requirement, for example, set to 300 × 200 or 400 × 300, and in some embodiments, the size may also be referred to as a pixel value. In specific implementation, the size of the maximum rectangular area can be scaled according to a proportional relationship between the size of the maximum rectangular area and the size of the display area, so as to obtain a display position of the tiled screen group, where the display position is usually included in the display area, so that the screen in the display position can be controlled in the display area, where the display position includes the size of the display size and the corresponding position coordinate of each screen in the display area.
When a user controls a certain area in the display position through the upper computer, a windowing signal can be sent to the screen corresponding to the area, and therefore the purpose of controlling any screen in the spliced screen group is achieved.
The invention provides a control method of a spliced screen group, which comprises the steps of firstly, acquiring the position coordinate and the screen size of each screen in the spliced screen group input by a user; further, according to the position coordinates and the screen size of each screen, the size of the maximum rectangular area corresponding to the spliced screen group is obtained; and then determining the display position of the spliced screen group based on the size of the preset display area and the size of the maximum rectangular area so as to control the screen in the display position. In the method, the size of the maximum rectangular area corresponding to the spliced screen group is obtained according to the position coordinates and the screen size of each screen in the spliced screen group input by a user, the display position of the spliced screen group is determined based on the size of the maximum rectangular area and the preset display area, and the screens in the spliced screen group are controlled at the display position.
The embodiment of the invention also provides another control method of the spliced screen group, which is realized on the basis of the method of the embodiment; the method mainly describes a specific process of obtaining the size of the maximum rectangular area corresponding to the mosaic screen group (realized by the following steps S204-S206), a specific process of determining the display position of the mosaic screen group (realized by the following steps S208-S212) based on the preset size of the display area and the size of the maximum rectangular area, and a specific process of controlling the screen in the display position (realized by the following steps S214-S218); as shown in fig. 2, the method comprises the following specific steps:
step S202, acquiring the position coordinates and the screen size of each screen in the spliced screen group input by the user.
In specific implementation, after the position coordinate and the screen size of each screen in the spliced screen group input by a user are obtained, the parameter information of each screen in the spliced screen group input by the user can be received; the parameter information comprises an identification code corresponding to each screen; and stores the position coordinates, screen size, and identification code of each screen.
The parameter information may include not only the identification code corresponding to each screen, but also display brightness, display color, display saturation, and the like corresponding to each screen. The identification code may refer to an ID (identity identification number) of a physical port corresponding to the screen, and generally, after the screen is windowed, when a user controls a certain screen through an upper computer, the upper computer may send a corresponding control instruction to the physical port of the screen to control the screen.
During specific implementation, a user can input the position coordinates, the screen sizes and the parameter information of each screen in the spliced screen group in the software of the upper computer, namely the user can set the position coordinates, the screen sizes and the parameter information of each screen in the spliced screen group in the software of the upper computer according to the requirements of the user; the upper computer can send the information input by the user to the bottom layer server so as to store the information input by the user.
And step S204, acquiring the position coordinates of the screen at the upper left corner and the position coordinates of the screen at the lower right corner in the spliced screen group.
Typically, the top left screen is the first screen in the first row of the group of tiles, and the bottom right screen is the last screen in the last row of the group of tiles.
And step S206, obtaining the size of the maximum rectangular area corresponding to the spliced screen group according to the position coordinate of the screen at the upper left corner, the position coordinate of the screen at the lower right corner and the screen size of the screen at the lower right corner.
Since it is cumbersome to input the coordinates of all the points of each screen, the above position coordinates may include only the coordinates of the upper left corner of the screen in the present embodiment. The coordinate difference can be obtained by the position coordinate of the screen at the upper left corner and the position coordinate of the screen at the lower right corner, and the size of the maximum rectangular area can be obtained by combining the coordinate difference with the screen size of the screen at the lower right corner. In a specific implementation, the screen size includes a width and a height of the screen, and the step S206 can be implemented by the following steps 10 to 13:
and 10, subtracting the abscissa value in the coordinate of the upper left corner of the screen at the upper left corner from the abscissa value in the coordinate of the upper left corner of the screen at the lower right corner to obtain an abscissa difference value.
And 11, subtracting the ordinate value in the upper left corner coordinate of the upper left corner screen from the ordinate value in the upper left corner coordinate of the lower right corner screen to obtain an ordinate difference value.
And step 12, adding the horizontal coordinate difference value to the width of the screen at the lower right corner to obtain the width of the maximum rectangular area.
And step 13, adding the difference value of the vertical coordinates to the height of the screen at the lower right corner to obtain the height of the maximum rectangular area. In a particular implementation, the dimensions of the largest rectangular area include the width and height of the largest rectangular area.
Taking the example that the spliced screen group comprises two screens, the process of obtaining the width and the height of the maximum rectangular area is described in detail. As shown in fig. 3, a schematic diagram of an arrangement of a tiled screen group is given, the tiled screen group in fig. 3 includes a screen 1 and a screen 2, where the screen 1 corresponds to the screen at the upper left corner, and the screen 2 corresponds to the screen at the lower right corner, and assuming that the coordinates of the upper left corner of the screen 1 are (100 ), the width of the screen 1 is 800, and the height is 600; the coordinate of the upper left corner of the screen 2 is (900,700), the width of the screen 2 is 800, the height of the screen 2 is 600, the abscissa value in the upper left corner of the screen 2 is subtracted by the abscissa value in the upper left corner of the screen 1 to obtain an abscissa difference value 900 and 100, which is 800, and the abscissa difference value is added by the width of the screen 2 to obtain a width of the maximum rectangular area 800+800, which is 1600; based on the manner of determining the horizontal coordinate difference, the vertical coordinate difference is determined to be 700-.
In step S208, the display size corresponding to the maximum rectangular area is determined according to the size of the display area.
In specific implementation, the size corresponding to the maximum rectangular area needs to be scaled according to the size of the display area, so that the display area can display the maximum rectangular area corresponding to the spliced screen group according to a certain proportion. The size of the display area comprises width and height, and the size of the maximum rectangular area comprises width and height; in some embodiments, the step S208 may be implemented by the following steps 20 to 24:
step 20, calculating a first aspect ratio of the maximum rectangular area based on the width and height of the maximum rectangular area. The first aspect ratio is the width of the largest rectangular area divided by the height of the largest rectangular area.
Step 21, calculating a second aspect ratio of the display area based on the width and the height of the display area. The second aspect ratio is the width of the display area divided by the height of the display area.
Step 22, judging whether the first aspect ratio is smaller than the second aspect ratio; if so, go to step 23, otherwise go to step 24.
And step 23, determining the height of the display area as the height of the display size corresponding to the maximum rectangular area, and determining the width of the display size according to the height of the display size.
When the first aspect ratio is smaller than the second aspect ratio, the height is taken as the main height, and at this time, the height of the display size of the maximum rectangular area is the height of the display area, and the width of the display size can be obtained by multiplying the height of the display size by the width of the maximum rectangular area and then dividing by the height of the maximum rectangular area.
And 24, determining the width of the display area as the width of the display size corresponding to the maximum rectangular area, and determining the height of the display size according to the width of the display size.
When the first aspect ratio is larger than the second aspect ratio, the width is taken as the main width, at this time, the width of the display size of the maximum rectangular area is the width of the display area, the width of the display size is multiplied by the height of the maximum rectangular area, and then the height of the display size can be obtained by dividing the width of the maximum rectangular area; when the first aspect ratio is equal to the second aspect ratio, the width of the display size of the maximum rectangular region is the width of the display region, and the height of the display size of the maximum rectangular region is the height of the display region.
Step S210, determining a scaling factor according to the size of the largest rectangular region and the display size.
In specific implementation, if the width is taken as the main value, the ratio of the width of the maximum rectangular area to the width of the display size is a proportionality coefficient; if the height is taken as the main, the ratio of the height of the maximum rectangular area to the height of the display size is a proportionality coefficient.
For example, assuming that the size of the preset display area is 300 × 200, the arrangement of the tiled screen groups is as shown in fig. 3, the width of the largest rectangular area is 1600, and the height is 1200; calculating to obtain a first aspect ratio of 1600/1200 and a second aspect ratio of 300/200; since 1600/1200 is <300/200, the height is dominant, i.e., the height of the display size is 200, the width of the display size is 200/(1200/1600) 267, and the scale factor is 1200/200 6.
And step S212, obtaining the display position of the spliced screen group based on the position coordinates and the proportionality coefficient of each screen in the spliced screen group.
In a specific implementation, the position coordinate may be an upper left corner coordinate, and the step S212 may be implemented by the following steps 30 to 33:
and step 30, subtracting the coordinates of the upper left corner of the screen at the upper left corner in the spliced screen group from the coordinates of the upper left corner of each screen to obtain a first coordinate corresponding to each screen.
Subtracting the abscissa value of the coordinate of the upper left corner of the screen at the upper left corner in the spliced screen group from the abscissa value of the coordinate of the upper left corner of the current screen for each screen in the spliced screen group to obtain the abscissa value of the first coordinate corresponding to the current screen; and subtracting the ordinate value of the upper left-hand coordinate of the screen at the upper left-hand corner in the spliced screen group from the ordinate value of the upper left-hand coordinate of the current screen to obtain the ordinate value of the first coordinate corresponding to the current screen. In a specific implementation, the coordinate of the upper left corner of the screen at the upper left corner is subtracted from the coordinate of the upper left corner of the screen at the upper left corner, so that the first coordinate of the screen at the upper left corner is (0,0), that is, the origin of coordinates.
And 31, dividing the first coordinate corresponding to each screen by the proportionality coefficient to obtain a second coordinate corresponding to each screen.
And dividing the abscissa value and the ordinate value in the first coordinate by the proportionality coefficient respectively aiming at each screen in the spliced screen group to obtain the abscissa value and the ordinate value of the second coordinate.
And 32, dividing the screen size of each screen by the scaling coefficient to obtain the corresponding display size of each screen. For example, if the width of the screen is 800, the height is 600, and the scale factor is 6, then the width of the screen in the corresponding display size is 800/6, and the height is 600/6.
And step 33, determining the display position of each screen based on the second coordinate and the display size corresponding to each screen to obtain the display position of the spliced screen group.
During specific implementation, the initial position of each screen can be located according to the second coordinate corresponding to each screen, the initial position is matched with the display size corresponding to each screen, and the display position of each screen can be obtained, wherein the display position comprises the initial position of the screen and a displayable area corresponding to the screen.
Step S214, monitoring the starting point and the ending point of the sliding of the mouse in the display position.
The user can operate the mouse in the upper computer to control the corresponding screen. And when the server monitors that the mouse slides on the display position corresponding to the spliced screen, acquiring a starting point and an ending point of the mouse sliding.
In step S216, the sliding area of the mouse is determined based on the start point and the end point.
Based on the start and end points, a swipe area of the mouse is calculated, which is typically a rectangular area. In a specific implementation, the coordinate corresponding to the ending point and the coordinate corresponding to the starting point may be used to calculate and determine the rectangular area corresponding to the sliding-through area.
Step S218, determining coordinates corresponding to the sliding region according to the proportional relationship between the size of the display region and the size of the maximum rectangular region, so as to control the screen corresponding to the coordinates corresponding to the sliding region.
The proportional relation between the size of the display area and the size of the maximum rectangular area is equivalent to the proportional coefficient, and according to the proportional coefficient and the sliding area, the actual corresponding coordinate (equivalent to the coordinate corresponding to the sliding area) of the sliding area can be obtained, and the actual corresponding coordinate corresponds to the coordinate in the maximum rectangular area corresponding to the spliced screen group, that is, according to the actual corresponding coordinate, the corresponding screen can be found in the spliced screen group to operate the screen, for example, open the window of the screen, or can be understood as opening the window of any screen in the spliced screen group by this method.
According to the control method of the spliced screen group, a user can flexibly set the arrangement mode of the spliced screen group and the size of each screen, and can also configure the screen group function of any screen so as to meet the configuration requirements of the user on different screens.
Corresponding to the control method of the spliced screen group, an embodiment of the present invention further provides a control device of the spliced screen group, as shown in fig. 4, the device includes:
the data acquisition module 40 is used for acquiring the position coordinates and the screen size of each screen in the spliced screen group input by the user; wherein, this concatenation screen group contains two at least screens.

In the method, the size of the maximum rectangular area corresponding to the spliced screen group is obtained according to the position coordinates and the screen size of each screen in the spliced screen group input by a user, the display position of the spliced screen group is determined based on the size of the maximum rectangular area and the preset display area, and the screens in the spliced screen group are controlled at the display position.
