Description

Technical Field

[0001] The present application relates to the field of splicing screens, and more specifically, to a method for calibrating a splicing screen, a splicing display device, a computer-readable storage medium, and a processor. Background Art

[0002] A spliced ​​screen is made up of multiple screens, such as four in a 2x2 setup or nine in a 3x3 setup. Each screen displays a different portion of the image, and then is stitched together to create a complete picture. Therefore, the wall-mounting of a spliced ​​screen requires extreme precision, as even the slightest misalignment will cause the image to misalign, which is more noticeable on low-resolution images.

[0003] At present, in response to this situation, the existing technology mainly relies on manual measurement with a ruler and then installation. There is also direct use of customized racks for fixed installation. However, these installation methods all rely on physical fixation and manual alignment, which has certain uncertainties and cannot resist the misalignment of the whole machine caused by changes in the external environment. For example, over time, the rack will loosen, causing part of the whole machine to shift, which will cause the display of the spliced ​​screen to be misaligned, affecting the splicing display effect.

[0004] Therefore, there is an urgent need for a method that can automatically adjust the display misalignment of the spliced ​​screen to reduce the uncertainty of manual adjustment.

[0005] The above information disclosed in the background technology section is only used to enhance the understanding of the background technology of the technology described in this article. Therefore, the background technology may contain certain information that does not form the prior art known in this country to those skilled in the art. Summary of the Invention

In this calibration method, the display distance is determined based on the actual distance of the target display screen and the other display screens, and the position of the display screen is adjusted when the display distance is not within the corresponding predetermined range, thereby realizing automatic adjustment of the position of the display screen. Compared with the prior art in which the position of the display screen is manually adjusted, the calibration method of the present application reduces the uncertainty of manual adjustment and improves the user experience, thereby solving the problem of the difficulty in automatically adjusting the display misalignment of the spliced ​​screen in the prior art.

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0019] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0020] As mentioned in the background technology, it is difficult to automatically adjust the display misalignment of the spliced ​​screen in the prior art. In order to solve the above problem, a typical embodiment of the present application provides a method for calibrating the screen of a spliced ​​screen, a spliced ​​display device, a computer-readable storage medium and a processor.

[0021] According to an embodiment of the present application, a method for calibrating a spliced ​​screen is provided.

[0022] Figure 1 FIG. 1 is a flow chart of a method for calibrating a spliced ​​screen according to an embodiment of the present application. Figure 2 and Figure 4 As shown, the spliced ​​screen is composed of multiple display screens, namely display screen A, display screen B, display screen C and display screen D, which are represented by A, B, C and D respectively in the figure. Each of the above display screens is used to display a sub-screen. The method includes the following steps:

[0023] Step S101, obtaining the actual distance between the target display screen and other display screens;

[0024] Step S102, determining a display distance based on the actual distance, wherein the display distance is the distance between each other sub-screen and the target sub-screen, the other sub-screens being the screens displayed on the other display screens, and the target sub-screen being the screen displayed on the target display screen;

[0025] Step S103, determining whether the displayed distance is within a corresponding predetermined range;

[0026] Step S104 : If at least one of the display distances is not within the corresponding predetermined range, adjust the position of the display image until the display distance is within the corresponding predetermined range.

[0027] In the above-mentioned method for calibrating the screen of the spliced ​​screen, first, the actual distance between the target display screen and the other display screens is obtained; then, the display distance is calculated based on the actual distance of the target display screen and the actual distance of the other display screens, the display distance being the distance of each other sub-screen relative to the target sub-screen, and then, whether the display distance is within the corresponding predetermined range is determined. Finally, if at least one of the display distances is not within the corresponding predetermined range, the position of the display screen is adjusted until the display distance is within the corresponding predetermined range, that is, the display screen is in a non-misaligned position. In this calibration method, the display distance is determined based on the actual distance of the target display screen and the other display screens, and if the display distance is not within the corresponding predetermined range, the position of the display screen is adjusted, thereby realizing automatic adjustment of the position of the display screen. Compared with the prior art method of manually adjusting the position of the display screen, the calibration method of the present application reduces the uncertainty of manual adjustment and improves the user experience, thereby solving the problem of the difficulty in automatically adjusting the display misalignment of the spliced ​​screen in the prior art.

[0028] In a specific embodiment of the present application, there are two ways to obtain the actual distance between the target display screen and the other display screen. The first way is to directly obtain the actual distance between the other display screen and the target display screen through a position sensor. The second way is to calculate the actual distance between the other display screen and the target display screen by obtaining the angle information of the other display screen relative to the target display screen. The following is a detailed example to introduce the second method of calculating the actual distance through angle information. Figure 2 As shown, when display screen A is selected as the target display screen, taking the calculation of the actual distance of display screen D relative to display screen A as an example, first, the angle information of display screen B relative to display screen A (i.e., α) and the distance L between display screens A and D are obtained. Then, it can be concluded that the distance of display screen D relative to display screen A in the X-axis direction is L*cosα, and the distance in the Y-axis direction is L*sinα.

[0029] Of course, in a specific application process, obtaining the distance between the target display screen and the other display screens is not limited to the above two methods. The distance between the target display screen and the other display screens may also be calculated in other ways.

[0030] In actual application, since the size and resolution of the above-mentioned display screen can be accurately obtained when leaving the factory, the length and width of a pixel can be calculated based on the size and resolution of the above-mentioned display screen. In this solution, the actual distance between the above-mentioned target display screen and the other display screen can be obtained through a position sensor. After obtaining the actual distance between the above-mentioned other display screen and the target display screen, the corresponding number of pixels of the above-mentioned other display screen relative to the above-mentioned target display screen, that is, the display distance, is calculated based on the length and width of the above-mentioned pixels. Subsequently, it is determined whether the above-mentioned number of pixels is within the above-mentioned predetermined range. If the above-mentioned number of pixels is not within the corresponding predetermined range, the position of the display screen is adjusted until the above-mentioned number of pixels is within the corresponding predetermined range.

[0031] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] In one embodiment of the present application, when the display distance is not within the corresponding predetermined range, adjusting the position of the display screen until the display distance is within the corresponding predetermined range includes: determining the movement distance of the corresponding other sub-screen when at least the display distance is not within the corresponding predetermined range, that is, determining the movement distance of the other sub-screen whose display distance is not within the predetermined range; and controlling the other sub-screen to move the movement distance. In this embodiment, adjusting the position of the display screen based on the determined movement distance can more accurately adjust the position of the display screen.

[0033] To more accurately and efficiently determine the movement distance, in another embodiment of the present application, determining the movement distance of the corresponding other sub-screen includes calculating the movement distance based on the display distance. Specifically, if the display distance is not within the corresponding predetermined range, subtracting the display distance from the predetermined range to obtain the movement distance.

[0034] In another embodiment of the present application, obtaining the actual distance between the target display screen and the other display screens includes: obtaining a first actual distance and a second actual distance, the first actual distance being a distance in a first direction, and the second actual distance being a distance in a second direction, the first direction being parallel to a length direction of the target display screen, and the second direction being parallel to a width direction of the target display screen; determining the display distance according to the actual distances includes: determining a first display distance according to the first actual distance, the first display distance being a distance between a picture on each of the other display screens and a picture on the target display screen in the first direction; determining a second display distance according to the second actual distance, the second display distance being a distance between a picture on each of the other display screens and a picture on the target display screen in the second direction; and adjusting, if the display distances are not within the corresponding predetermined ranges, the position of the display screen until the display distances are within the corresponding predetermined ranges, including: adjusting, if at least one of the first display distances and / or at least one of the second display distances are not within the corresponding predetermined ranges, the position of the display screen until all of the first display distances and all of the second display distances are within the corresponding predetermined ranges. In this embodiment, the actual distances in two directions are obtained, and the display distances in two directions are subsequently obtained based on the actual distances, that is, the first display distance is determined based on the first actual distance, and the second display distance is determined based on the second actual distance. When at least one of the above-mentioned first display distances and / or at least one of the above-mentioned second display distances is not within the corresponding above-mentioned predetermined ranges, the position of the display screen is adjusted. This ensures that the position of the display screen can be adjusted more accurately, and further solves the problem in the prior art that it is difficult to automatically adjust the display misalignment of the spliced ​​screen.

[0035] In a specific embodiment of the present application, when at least one of the above-mentioned first display distances and / or at least one of the above-mentioned second display distances are not within the corresponding above-mentioned predetermined ranges, the display screen can be adjusted upward, downward, left, and right according to the first display distance and / or at least one of the above-mentioned second display distances.

[0036] Of course, in actual application, the display image is not limited to being adjusted upward, downward, leftward, or rightward, but may also be adjusted in other directions or in other ways (such as rotation, etc.).

[0037] In one embodiment of the present application, when the display distance is not within the corresponding predetermined range, the position of the display screen is adjusted until the display distance is within the corresponding predetermined range, including: when at least the first display distance and / or at least one of the second display distances is not within the corresponding predetermined range, determining the first moving distance and the second moving distance of the corresponding other sub-screen, the first moving distance being the moving distance in the first direction, and the second moving distance being the moving distance in the second direction; controlling the other sub-screen to move the first moving distance in the first direction; and controlling the other sub-screen to move the second moving distance in the second direction. In this embodiment, the other sub-screens are controlled to move in the first direction and the second direction according to the first moving distance and the second moving distance, thereby ensuring that the position of the display screen can be adjusted more accurately.

[0038] The present application also provides a splicing screen image calibration device. It should be noted that the splicing screen image calibration device of the present application can be used to execute the splicing screen image calibration method provided in the present application. The splicing screen image calibration device provided in the present application is described below.

[0039] Figure 3 Schematic diagram of a device for calibrating a spliced ​​screen according to an embodiment of the present application. Figure 2 As shown, the spliced ​​screen is composed of multiple display screens, each of which is used to display a sub-picture. The device includes:

[0040] An acquisition unit 10 is used to acquire the actual distance between the target display screen and other display screens;

[0041] A first determining unit 20 is configured to determine a display distance based on the actual distance, wherein the display distance is the distance between each other sub-screen and the target sub-screen, the other sub-screens being the screens displayed on the other display screens, and the target sub-screen being the screen displayed on the target display screen;

[0042] A second determining unit 30 is configured to determine whether the displayed distance is within a corresponding predetermined range;

[0043] The adjusting unit 40 is configured to adjust the position of the display image when at least one of the display distances is not within the corresponding predetermined range, until the display distance is within the corresponding predetermined range.

[0044] In the above-mentioned splicing screen screen calibration device, an acquisition unit is used to obtain the actual distance between the target display screen and other display screens; a first determination unit is used to determine the display distance based on the actual distance, the display distance being the distance between each other sub-screen and the target sub-screen, the other sub-screen being the screen displayed on the other display screen, and the target sub-screen being the screen displayed on the target display screen; a second determination unit is used to determine whether the display distance is within a corresponding predetermined range; an adjustment unit is used to adjust the position of the display screen when at least one of the display distances is not within the corresponding predetermined range until the display distance is within the corresponding predetermined range, that is, each other sub-screen is in a non-misaligned position. In this calibration method, the display distance is determined based on the actual distance obtained between the target display screen and the other display screen, and when the display distance is not within the corresponding predetermined range, the position of the display screen is adjusted, thereby achieving automatic adjustment of the position of the display screen. Compared with the prior art method of manually adjusting the position of the display screen, the calibration method of the present application reduces the uncertainty of manual adjustment and improves the user experience, thereby solving the problem of the difficulty in automatically adjusting the display misalignment of the splicing screen in the prior art.

[0045] In one embodiment of the present application, the adjustment unit includes a first determination module and a first control module. The first determination module is configured to determine the movement distance of the corresponding other sub-screen when at least the display distance is not within the corresponding predetermined range, i.e., to determine the movement distance of the other sub-screen whose display distance is not within the predetermined range; and the first control module is configured to control the other sub-screen to move the aforementioned movement distance. In this embodiment, the position of the display screen is adjusted based on the determined movement distance, thereby enabling more accurate adjustment of the position of the display screen.

[0046] To more accurately and efficiently obtain the movement distance, in another embodiment of the present application, the second determination unit includes a calculation module for calculating the movement distance based on the displayed distance. Specifically, if the displayed distance is not within the corresponding predetermined range, the displayed distance is subtracted from the predetermined range to obtain the movement distance.

[0047] In another embodiment of the present application, the acquisition unit includes an acquisition module for acquiring a first actual distance and a second actual distance, the first actual distance being the distance in a first direction, and the second actual distance being the distance in a second direction, the first direction being parallel to the length direction of the target display screen, and the second direction being parallel to the width direction of the target display screen; the first determination unit includes a second determination module and a third determination module, the second determination module being used to determine a first display distance based on the first actual distance, the first display distance being the distance between the images on each of the other display screens and the image on the target display screen in the first direction; the third determination module being used to determine a second display distance based on the second actual distance, the second display distance being the distance between the images on each of the other display screens and the image on the target display screen in the second direction; the adjustment unit also includes an adjustment module for adjusting the position of the display screen until all of the first display distances and all of the second display distances are within the corresponding predetermined range when at least one of the first display distances and / or at least one of the second display distances is not within the corresponding predetermined range. In this embodiment, the actual distances in two directions are obtained, and the display distances in two directions are subsequently obtained based on the actual distances, that is, the first display distance is determined based on the first actual distance, and the second display distance is determined based on the second actual distance. When at least one of the above-mentioned first display distances and / or at least one of the above-mentioned second display distances is not within the corresponding above-mentioned predetermined ranges, the position of the display screen is adjusted. This ensures that the position of the display screen can be adjusted more accurately, and further solves the problem in the prior art that it is difficult to automatically adjust the display misalignment of the spliced ​​screen.

[0048] In a specific embodiment of the present application, when at least one of the above-mentioned first display distances and / or at least one of the above-mentioned second display distances are not within the corresponding above-mentioned predetermined ranges, the display screen can be adjusted upward, downward, left, and right according to the first display distance and / or at least one of the above-mentioned second display distances.

[0049] Of course, in actual application, the display image is not limited to being adjusted upward, downward, leftward, or rightward, but may also be adjusted in other directions or in other ways (such as rotation, etc.).

[0050] In one embodiment of the present application, the adjustment unit further includes a fourth determination module, a second control module, and a third control module, wherein the fourth determination module is used to determine the first moving distance and the second moving distance of the corresponding other sub-screen when at least the first display distance and / or at least one of the second display distances is not within the corresponding predetermined range, the first moving distance being the moving distance in the first direction, and the second moving distance being the moving distance in the second direction; the second control module is used to control the other sub-screen to move the first moving distance in the first direction; and the third control module is used to control the other sub-screen to move the second moving distance in the second direction. In this embodiment, the other sub-screens are controlled to move in the first direction and the second direction according to the first moving distance and the second moving distance, thereby ensuring that the position of the display screen can be adjusted more accurately.

[0051] In a typical embodiment of the present application, a splicing display device is provided, comprising: a splicing screen, a position sensor, one or more processors, a memory and one or more programs, wherein the splicing screen is composed of multiple display screens, the position sensors are arranged on the display screens one by one, the processors are respectively communicated with the position sensors and the splicing screen, the multiple position sensors are used to obtain the actual distance between other display screens and the target display screen, and send it to the processors, the one or more programs are stored in the memory and are configured to be executed by the one or more processors, and the one or more programs include programs for executing any one of the above methods.

[0052] The above-mentioned splicing display device includes a splicing screen, a position sensor, one or more processors, a memory, and one or more programs. The processor of the above-mentioned splicing display device can execute any of the above-mentioned splicing screen image calibration methods. In the above-mentioned splicing screen image calibration method, the display distance is determined based on the actual distance between the target display screen and other display screens. When the display distance is not within the corresponding predetermined range, the position of the display screen is adjusted, thereby realizing automatic adjustment of the position of the display screen. Compared with the manual adjustment of the position of the display screen in the prior art, the calibration method of the present application reduces the uncertainty of manual adjustment and improves the user experience, thereby solving the problem of the difficulty in automatically adjusting the display misalignment of the splicing screen in the prior art.

[0053] In one embodiment of the present application, any two of the above-mentioned display screens are the same, and any two of the above-mentioned position sensors are the same, and one of the above-mentioned position sensors is a first position sensor and the other is a second position sensor. The position of the center of the above-mentioned first position sensor relative to the center of the corresponding above-mentioned display screen (that is, the display screen where the first position sensor is located) is a first position, and the position of the center of the above-mentioned second position sensor relative to the center of the corresponding above-mentioned display screen (that is, the display screen where the second position sensor is located) is a second position. The above-mentioned first position and the above-mentioned second position are the same, that is, the position sensors on the above-mentioned any two display screens are located at the same position on the corresponding display screen, which ensures that the actual distance of the display screen can be obtained more accurately.

[0054] In a specific embodiment of the present application, the projection of the center of the above-mentioned sensor on the back of the corresponding above-mentioned display screen coincides with the center of the back of the above-mentioned display screen, that is, the above-mentioned position sensor is located in the middle of the back of the above-mentioned display screen. The above-mentioned position sensor includes a generator and a receiver. After the target display screen is determined, the receiver on the target display screen is turned on to be in a working state, and the generators of other display screens except the target display screen are controlled to connect with the receiver on the target display screen, so as to obtain the actual distance of the other display screens, so that the position and angle of the other display screens relative to the target display screen can be further accurately obtained.

[0055] In another embodiment of the present application, the spliced ​​display device further includes: one or more processors, a memory, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, and the one or more programs include means for executing any one of the above methods.

[0056] In order to make those skilled in the art more clearly understand the technical solution of this application, the following will be described with reference to specific embodiments:

[0057] like Figure 4 As shown, for a spliced ​​screen composed of four display screens, when display screen A is selected as the target display screen, for display screen B (i.e. other display screens), when display screen B is not in the position (i.e. Figure 2 The distance between display B and display A in the X-axis direction (i.e., the first direction) obtained by the position sensor is 2000 mm, and the distance in the Y-axis direction is 0 mm. When display B is misaligned (i.e., Figure 2For example, the distance between display B and display A in the X-axis direction, as measured by the position sensor, is 2210 mm, and in the Y-axis direction, 10 mm. Based on the factory dimensions and resolution of the display, the length of a pixel is 1.042 mm, and the width of a pixel is 0.926 mm. If display B is misaligned, it can be calculated that the number of pixels in the X-axis direction relative to display A is 2121, and the number of pixels in the Y-axis direction is 11. Since display B is not misaligned, the number of pixels in the X-axis direction relative to display A is 1920, and the number of pixels in the Y-axis direction is 0. Therefore, display B needs to be moved by 2121 - 1920 = 201 pixels in the X-axis direction and 11 - 0 = 11 pixels in the Y-axis direction.

[0058] The above-mentioned image calibration device for the splicing screen includes a processor and a memory. The above-mentioned acquisition unit, first determination unit, second determination unit and adjustment unit are all stored in the memory as program units, and the processor executes the above-mentioned program units stored in the memory to realize corresponding functions.

The core can be set to one or more, and the problem of dislocation of the display of the splicing screen that is difficult to automatically adjust in the existing technology can be solved by adjusting the core parameters.

[0060] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.
