Embodiment 1

[0023] figure 1 It is an implementation flowchart of an LED display-based LED cabinet positioning method provided by an embodiment of the present invention, and is described in detail as follows:

[0024] In step S101, the number of LED cabinets in the LED display screen and the order in which the LED cabinets are connected are obtained;

[0025] Connect each LED box in the LED display, and configure the serial number of each LED box according to the order of connection.

[0026] In step S102, according to the quantity and the order, configure the serial number of each LED box;

[0027] Configure the unique identification of each LED box. According to the quantity and the order, the serial number of each LED box is configured through a sorting function, and the serial number of each LED box is different.

[0028] Establish a corresponding relationship between the serial number of the LED cabinet and the unique identifier of the LED cabinet, and record and store it, wherein ...

Embodiment 2

[0034] refer to figure 2 , figure 2 It is an implementation flowchart of step S103 of an LED display-based LED cabinet positioning method provided by an embodiment of the present invention, and is described in detail as follows:

[0035] In step S201, the resolution of the video image is obtained, and the resolution is converted into a preset resolution;

[0036] Wherein, the scaling ratio can be generated through the resolution of the video image and the set resolution, and the corresponding compression or pixel filling can be performed through the scaling ratio, so as to convert the resolution into a preset resolution.

[0037] In step S202, the video image is divided into video image areas of each of the LED cabinets according to a preset division order, the division order includes from top to bottom and from left to right;

[0038] Wherein, the preset size can be set by the user, or the default size of the system can be used.

[0039] In step S203, the coordinates of ...

Embodiment 3

[0045] refer to image 3 , image 3 It is an implementation flowchart of step S104 of an LED display-based LED cabinet positioning method provided by an embodiment of the present invention, and is described in detail as follows:

[0046] In step S301, in the positioning coordinates of the video image area displayed by the LED box, according to the serial number, determine the LED box corresponding to the serial number;

[0047] In step S302, extract the determined positioning coordinates of the LED box corresponding to the serial number as the positioning coordinates corresponding to the serial number;

[0048] In step S303, the positioning coordinates corresponding to the serial number are configured in the LED box.

[0049] Wherein, in the LED box, configure the positioning coordinates corresponding to the serial number, and judge whether the serial number is the last serial number, and stop the configuration when the serial number is the last serial number.

[0050] In t...

Abstract

The invention is applicable to the technical field of LED (Light Emitting Diode) display and provides an LED box body positioning method and device based on an LED display screen and the LED display screen. The method comprises the following steps: obtaining the number of LED box bodies in the LED display screen and the connecting sequence of the LED box bodies; according to the number and the sequence, configuring a sequence number of each LED box body; obtaining video images displayed in the LED display screen, and detecting the video images to obtain positioning coordinates of a video image area displayed by each LED box body; according to the sequence numbers, configuring the positioning coordinates of the LED box bodies. The LED box body positioning method and device based on the LED display screen and the LED display screen have the advantages that the LED box body positioning efficiency is improved, the LED box bodies are enabled to be capable of displaying correct video image areas, and the LED display screen can display correct video images.

Description

technical field [0001] The invention belongs to the technical field of LED displays, and in particular relates to an LED display-based LED cabinet positioning method, device and LED display. Background technique [0002] An LED display screen usually consists of a plurality of LED cabinets, each LED cabinet displays an area of ​​a video source image, and the corresponding display area of ​​each LED cabinet is usually positioned manually. For example, connect each LED cabinet according to certain rules; or first locate the area setting according to the fixed mode, and then relocate the area according to the disordered display image on the LED display body. [0003] However, the existing LED cabinet positioning method requires manual positioning. One LED cabinet positioning operation can only locate one LED cabinet. Since there are many LED cabinets in the LED display screen, manual positioning of the LED The workload of the LED cabinet in the display screen will be very larg...
