The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
For convenience of understanding, a system architecture applying the display screen matching method proposed by the present application is first described:
please refer to fig. 1, which is a schematic diagram of a system architecture for implementing the method for configuring a display screen according to the present application. The system architecture as illustrated in fig. 1, comprising: display screen 110, controller 120, device 130.
The display screen 110 may be formed by splicing a plurality of display modules, each display module having a receiving card for receiving and transmitting images. For example, in fig. 1, the display screen 110 is formed by splicing 16 display elements (each rectangular box represents one display element).
As an example, the display screen 110 may be an LED display screen, and correspondingly, the display component is an LED box in the LED display screen.
The controller 120, also called a sending card, is responsible for signal source processing, image transmission, and the like.
Each portal on the controller 120 may have at least one display element connected thereto, and different display elements connected to the same portal may be cascaded in sequence. In other words, a display assembly may access a portal on the controller 120, and the display assembly has an access location on the portal.
For example, in fig. 1, the controller 120 has 4 ports (hereinafter, for convenience of description, the 4 ports are respectively identified as port 1, port 2, port 3, and port 4 in the order from left to right in fig. 1), and each port is accessed with 4 display elements, and the cascade order of the 4 display elements on the ports, that is, the access positions, is indicated by the arrow direction.
As one example, the device 130 may have image capture functionality, e.g., the device 130 is a smartphone.
As another example, when the device 130 does not have an image capturing function, an image capturing device (not shown in fig. 1) may be further included in the system architecture shown in fig. 1, and the image capturing device is communicatively connected to the device 130.
Thus, the description of the system architecture shown in fig. 1 is completed.
On the basis of the system architecture shown in fig. 1, the following embodiments are used to describe the screen matching method proposed in the present application:
referring to fig. 2, a flowchart of an embodiment of a method for configuring a display screen according to an exemplary embodiment of the present application is provided, where in one example, the method is applicable to the apparatus 130 illustrated in fig. 1, and includes the following steps:
step 201: and acquiring a display screen image.
In the embodiment of the application, the display screen image comprises splicing information of the display screen formed by splicing the display components.
As an example, the mosaic information of the display component includes: the identification of the net port accessed by the display component and information for indicating the access position of the display component on the net port (hereinafter referred to as access position information).
In this example, as an optional implementation manner, the portal identifier and the access position information in the splicing information may be combined according to a preset combination rule, for example, the preset combination rule is [ portal identifier-access position information ]. Wherein the access location information may be represented by a concatenated sequence number.
For example, in fig. 1, the display module located in the first row and the first column on the display screen 110 is accessed to the portal 1, and the cascade sequence of the display module in the 4 display modules accessed by the portal 1 is the first position, that is, the access position of the display module on the portal 1 is the first position, and according to the above description, the splicing information of the display module may be [ 1-1 ].
As another example, the display elements in the first row and the third column on the display screen 110 are accessed to the portal 2, and the cascade sequence of the display elements in the 4 display elements accessed by the portal 4 is the third position, that is, the access position of the display elements on the portal 4 is the third position, and according to the above description, the splicing information of the display elements may be [ 4-3 ].
In an application, each display component on the display screen may be controlled by the controller of the display screen to simultaneously display its corresponding mosaic information, for example, as shown in fig. 3, which is an example of content displayed on each display component in the display screen.
When each display component simultaneously displays the corresponding splicing information on the display screen, the device 130 may shoot the display screen to obtain a display screen image; or the display screen is captured by the image capture device and the device 130 obtains the display screen image from the image capture device.
Step 202: and determining the position information of each display assembly in the display screen according to the splicing information of each display assembly in the display screen image.
In an application, since each display component on the display screen displays content under the control of the controller of the display screen, the controller of the display screen knows the content displayed on each display component on the display screen. Of course, in the embodiment of the present application, the content displayed on the display component is the splicing information of the display component, that is, the controller of the display screen knows the corresponding relationship between the display component and the splicing information.
Based on this, the device 130 may obtain the stitching information for each display component on the display screen from the controller of the display screen. Further, the device 130 may further identify splicing information of each display component from the display screen image acquired in step 201, and then may determine, for each identified splicing information, a position of the display component corresponding to the splicing information in the display screen according to a position of the splicing information in an area of the display screen image that includes the display screen.
The following description will be given specifically to how to determine the position information of each display component in the display screen according to the splicing information of each display component in the display screen image, and will not be described in detail here.
Step 203: and matching the display screen according to the position information of each display component on the display screen.
In application, after the device 130 performs step 202, the position information of each display component in the display screen determined in step 202 may be sent to the controller of the display screen, so that the controller of the display screen automatically performs screen matching.
The following is a brief description of the process of the controller screen configuration:
as can be seen from the above description, the controller of the display screen knows the corresponding relationship between the display components and the splicing information, and in this step 203, the controller can obtain the position information of each display component in the display screen, so that the controller can determine the corresponding relationship between the splicing information and the position information, and the corresponding relationship can be referred to in fig. 7. Furthermore, the splicing information comprises the identification of the net port accessed by the display component and the information of the access position, so that the controller of the display screen can write the position information corresponding to the splicing information into the corresponding receiving card according to the splicing information and the net port corresponding to the splicing information according to the information of the access position, and the screen matching of the display screen is completed.
The description of the embodiment shown in fig. 2 is thus completed.
According to the embodiment, the display screen can be matched through the embodiment after the display screen is installed, so that the display components can be spliced randomly in the installation process of the display screen, and the installation difficulty of the display screen is greatly reduced; meanwhile, the position information of each display assembly in the display screen can be automatically determined according to the splicing information of each display assembly in the display screen image, so that the display screen can be automatically matched after the display screen is installed, and the screen matching efficiency is greatly improved.
How to determine the position information of each display component in the display screen according to the splicing information of each display component in the display screen image is described by the embodiment shown in fig. 4 as follows:
as shown in fig. 4, the method comprises the following steps:
step 401: and converting the splicing information of each display component in the display screen image into text data corresponding to each display component.
As an example, the splicing information of each display component in the display screen image can be converted into text data corresponding to each display component through a character recognition algorithm. This conversion process is briefly described below by taking the OCR (Optical Character Recognition) algorithm as an example:
overall, the OCR algorithm is divided into two steps, image processing and text recognition, respectively. Among these, image processing typically includes: graying, binaryzation, noise reduction, inclination correction, character segmentation and the like, and each character in the display screen image can be obtained through an image processing process. Text recognition typically includes: extracting features, reducing dimensions of the features, and inputting the extracted features or the features subjected to dimension reduction into a trained classifier, wherein the output result of the classifier is recognized text data.
As shown in fig. 5, an example of converting the splicing information displayed by each display component in fig. 3 into text data is shown.
Step 402: and sequencing the text data corresponding to each display component according to a set text data sequencing format to obtain a text data sequence.
In the embodiment of the application, the arrangement format of the text data corresponding to each display component can be set according to the arrangement sequence of each display component on the display screen.
In this step 402, the text data corresponding to each display component is sorted according to the above-mentioned set text data arrangement format to obtain a text data sequence, for example, as shown in fig. 6, the text data sequence is an example of the text data sequence.
Through the processing, the arrangement sequence of the text data corresponding to each display component is consistent with the arrangement sequence of each display component on the display screen. For example, the text data [ 4-1 ] is located in the 2 nd row and 3 rd column in the text data sequence, and the display component corresponding to the text data is also located in the 2 nd row and 3 rd column on the display screen.
Step 403: and determining the position information of the display component corresponding to each text datum in the display screen according to the position information of each text datum in the text datum sequence.
As can be seen from the above description, the arrangement order of the text data corresponding to each display module is consistent with the arrangement order of each display module on the display screen, and therefore, in this step 403, the position information of the display module corresponding to each text data in the display screen can be determined according to the position information of each text data in the text data sequence.
As an example, the number of rows and columns of each text data in the text data sequence may be determined, the number of rows and columns may be determined as the position information of the text data, and the position information of the text data may be further determined as the position information of the display component corresponding to the text data in the display screen.
For example, in fig. 6, when the text data [ 4-1 ] is located in the 2 nd row and 3 rd column in the text data sequence, the position information of the text data is denoted as (2, 3), and similarly, the position information of the display element corresponding to the text data on the display screen is also denoted as (2, 3), indicating that the display element corresponding to the text data is located in the 2 nd row and 3 rd column in the display screen.
As another example, coordinate values corresponding to each text data in a preset coordinate system may be determined, the coordinate values may be determined as position information of the text data, and the position information of the text data may be further determined as position information of a display component corresponding to the text data in a display screen.
For example, in fig. 7, when the text data [ 4-1 ] is located in the 2 nd row and 3 rd column in the text data sequence, the position information of the text data is denoted as (2, 3), and similarly, the position information of the display element corresponding to the text data on the display screen is also denoted as (2, 3), indicating that the display element corresponding to the text data is located in the 2 nd row and 3 rd column in the display screen.
So far, the description of the embodiment shown in fig. 4 is completed.
By the embodiment shown in fig. 4, the position information of each display component in the display screen is determined according to the splicing information of each display component in the display screen image.
