Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of LED display, and particularly relates to a method for obtaining an LED dot address, an LED dot system, and a storage medium. Background Art
[0002] In LED display applications, such as guardrail tubes, display screens, etc., it is required that LED dots have initial addresses. After the controller reads the initial addresses, it writes the reset addresses into the dots corresponding to the initial addresses. During application, the controller writes display data according to the reset addresses of the dots to achieve display. A dot consists of two parts, one is the R, G, B three-color light chips, and the other is the LED driver chip. The dot address is integrated in the LED driver chip. The LED driver chip receives the data from the controller and maps the data into a PWM dimming signal to control the R, G, B light chips to emit light.
[0003] In the existing dot address reset scheme, the dot outputs its own initial address bit by bit in the form of the R, G, B light chips being on or off. A photosensitive diode or a photosensitive triode is used to scan each dot in turn. According to the on or off state of each dot, the initial addresses of each dot in the system are obtained. Then the controller addresses the corresponding dot through the initial address and writes the reset address into the corresponding dot. During normal application, display data is written to the reset addresses of each dot to drive the RGB light chips to display. However, the existing dot address reset method has the following disadvantages: First, the scanning speed of each dot is quite slow. Assuming a dot has 8-bit addresses and there are a total of 128 dots, 8 * 128 scans are required, and the efficiency is quite low. Second, when using a photosensitive diode to scan each dot one by one, the on or off state of adjacent dots affects the detection of the current dot, resulting in a relatively high false detection rate.
[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention
[0005] In view of the above deficiencies of the existing technology, the purpose of the present invention is to provide a method for obtaining an LED dot address, an LED dot system, and a storage medium, so as to solve the problems of low efficiency and high false detection rate in the existing dot address reset scheme.
[0006] The technical solution of the present invention is as follows:
[0007] In the first aspect, the present invention provides a method for obtaining an LED dot address, which includes:
[0008] The controller outputs an address matching instruction to control each dot to output its own address through two states of on and off;
[0009] The controller controls the imaging device to obtain an initial address image of the on and off states of each dot;
[0010] The controller obtains the initial addresses of each light point based on the initial address image.
[0011] A further setting of the present invention, the step that the controller obtains the initial addresses of each light point based on the initial address image includes:
[0012] Obtain the position coordinates of each light point;

[0016] Control the imaging device to obtain the lighting state image of each light point;
[0017] Obtain the position coordinates of each light point according to the lighting state image.
[0018] A further setting of the present invention, the initial address image is the bit image of each bit address of the initial address, and the step that the controller obtains the initial addresses of each light point according to the position coordinates of each light point and the initial address image includes:
[0019] Judge the on and off states of the light points according to the pixel values of the position coordinates of each light point in the bit image;
[0020] Obtain the initial addresses of the light points according to the on and off states of each light point.
[0021] A further setting of the present invention, the step that obtains the position coordinates of each light point according to the lighting state image includes:
[0022] Calculate the sum of the continuous m*n pixel points occupied by the light points in the lighting state image to obtain the first pixel point value;
[0023] Compare the first pixel point value with the first preset pixel point value. If the first pixel point value is greater than the first preset pixel point value, it means that there is a light point at the current position coordinate. If the first pixel point value is less than or equal to the first preset pixel point value, it means that the current position coordinate is the transition position between the light points.
[0024] A further setting of the present invention, the step that the controller outputs an address matching instruction to control each light point to output its own address through two states of on and off includes:
[0025] The controller outputs the lowest-bit address matching instruction to the light points. The light points match the lowest bit of their own addresses with the address field of the lowest-bit address matching instruction. If both are high level or low level, the light is on; otherwise, the light is off.
[0026] Obtain the lighting state image and obtain the lowest-bit addresses of each light point according to the lighting state image.
[0027] Repeat the above steps until all bit addresses of each light point are traversed.
[0028] In a further setting of the present invention, in the step where the controller outputs an address matching instruction to control each light point to output its own address through two states of on and off, the controller outputs an address matching instruction to control the light point to output each bit of the initial address bit by bit.
[0029] In a further setting of the present invention, there are at least two light points. In the step where the controller outputs an address matching instruction to control each light point to output its own address through two states of on and off, each light point outputs its own initial address simultaneously.
[0030] In a second aspect, the present invention also provides an LED light point system, which includes a controller, a camera device and a plurality of light points.

[0041] Please refer to Figures 1 to 2 simultaneously. The present invention provides a preferred embodiment of a method for obtaining the dot address of an LED lamp.
[0042] In some embodiments, as Figure 1 shown, the present invention provides a method for obtaining the dot address of an LED lamp, which includes the steps of:
[0043] S100. The controller outputs an address matching instruction to control each dot to output its own address through two states of on and off;
[0044] Specifically, the dot includes a driving chip and a three-color lamp chip, namely an R lamp chip, a G lamp chip, and a B lamp chip, and the dot address is integrated in the driving chip. The dot's own address can be displayed through its two states of on and off. Therefore, before the initial address image is obtained by the imaging device, the controller will output an address matching instruction to control the on and off states of each dot. Please refer to Figure 2 simultaneously. The number of dots is at least two, such as Figure 2 dot 1, dot 2, dot 3, dot N - 1, and dot N in . When the controller outputs an address matching instruction to control each dot to output each bit of the initial address bit by bit, each dot outputs its own initial address simultaneously. It should be noted that the initial address of the dot refers to the node address before the reset address is set, or the reset address after the reset address is set, and the address of any other node.
[0045] S200. The controller controls the imaging device to obtain an initial address image of the on and off states of each dot;
[0046] Specifically, the imaging device may be a camera. The initial address image refers to the image obtained by the imaging device capturing the on and off states of the light points before the light points are further reset for their addresses. The imaging device is electrically connected to the controller and is controlled by the controller. When the controller controls each light point to output its respective light point address in a flashing manner, the controller controls the imaging device to capture the on and off states of each light point to obtain the initial address image of each light point. Since the light points output their own addresses bit by bit according to the address matching instructions of the controller for the initial address, the imaging device capturing the images of the on and off states of the light points is to capture the bit images of each bit of the initial address.
[0047] S300. The controller obtains the initial addresses of each light point according to the initial address image.
[0048] Specifically, there are three working modes for the light points: one is the normal working mode, which converts the data input from the DATA pin of the controller into a PWM signal to control the R lamp chip, G lamp chip, and B lamp chip to emit light; the second is the light point initial address bit-by-bit output mode, in which the light point outputs its own initial address bit by bit in a flashing manner according to the command of the controller; the third is the address reset mode, which locates the corresponding light point according to the obtained initial address and writes the reset address into the memory of the corresponding light point.
[0049] When the controller outputs an address matching instruction to control the bit-by-bit output of the initial address of each bit of the light points, after the imaging device acquires an image of the first bit address of the initial address of all the light points in the on and off states, the controller controls the light points to output the second bit address of the initial address through the output address matching instruction. The imaging device further acquires an image of the second bit address of the initial address of the light points, and stops until all bits of the initial address are output. Thereafter, the controller can obtain the initial address of each light point based on the obtained initial address image. In this way, in the address reset mode, the controller can address the corresponding light point according to the obtained initial address of the light point. The controller sends an address reset instruction, which includes the initial address and the reset address. All the light points in the system can receive this address reset instruction. If the address in the initial address field received by the light point matches its own initial address, the address in the reset address field is saved. After writing the reset addresses corresponding to all the calculated initial addresses into the light points, the reset address is programmed into the non-volatile memory of the light point uniformly according to the instruction of the controller. Among them, the memory of the light point is generally a non-volatile memory, including OTP, MTP, EEPROM, and FUSE, etc. In the bit-by-bit output mode of the initial address of the light point, according to the storage capacity of the controller, it can be selected to calculate the initial address uniformly after all the address bits are photographed, or calculate one by one after taking one picture. After obtaining the initial addresses of all the light points, address the corresponding light point according to this initial address, and write the reset address into the corresponding light point.
[0050] Among them, the reset address written into the light point in the address reset mode is generally the position coordinate of the light point in the system, or the arrangement order of the light points in the system, which is set according to the actual requirements of the system. There is no special requirement in this example. It can be understood that the current required for simultaneous programming is too large, and it is also possible to select to program another light point after one light point is programmed, or to program another part of the light points after a part of the light points are programmed.
[0051] In the above technical solution, the present invention controls each light point to output its own address in two states of on and off, and further scans all the light points through a camera to obtain an initial address image, so that the initial address of each light point can be read according to the initial address image. Compared with the existing method of scanning one by one using a photodiode, it not only improves the efficiency of obtaining the light point address, but also reduces the false detection rate. In this way, the obtained initial address can be written into the reset address in parallel, which can not only greatly improve the production efficiency, but also improve the production yield.
[0052] In some embodiments, the step of the controller obtaining the initial address of each light point according to the initial address image includes:
[0053] S310. Obtain the position coordinates of each light point;
[0054] In some embodiments, the step of obtaining the position coordinates of each light point includes:
[0055] S311. Control each light point to light up;
[0056] S312. Control the imaging device to obtain the lighting state image of each light point;
[0057] S313. Obtain the position coordinates of each light point according to the lighting state image.
[0058] Specifically, after the light point system is powered on, the controller sends a command to make all the light points in the light point system enter the full lighting mode. Then, control the imaging device to take a picture of all the light points after they are lit to obtain the lighting state image. The controller can calculate the position coordinates of each light point in the light point system according to the lighting state image.
[0059] Further, the step of obtaining the position coordinates of each light point according to the lighting state image includes:
[0060] S3131. Calculate the sum of the continuous m * n pixel points occupied by the light point in the lighting state image to obtain the first pixel point value;
[0061] S3132. Compare the first pixel point value with the first preset pixel point value. If the first pixel point value is greater than the first preset pixel point value, it means that there is a light point at the current position coordinate. If the first pixel point value is less than or equal to the first preset pixel point value, it means that the current position coordinate is the transition position between light points.
[0062] Specifically, assume that a light point in the captured initial address image occupies continuous m rows * n columns of pixel points. Calculate the sum of the m * n pixel points in the initial address image to obtain the first pixel point value, and compare the first pixel point value with the first preset pixel point value. If the first pixel point value is greater than the first preset pixel point value, it means that there is a light point at that position. If the first pixel point value is less than or equal to the first preset pixel point value, it means that that position is the transition position between light points. According to this method, calculate the coordinates of all the light point positions in the initial address image. It should be noted that the values of m and n are determined by the size of the light points in the picture captured by the camera. The first preset pixel point value is determined according to the empirical values obtained during debugging.
[0063] S320. Obtain the initial address of each light point according to the position coordinates of each light point and the initial address image.
[0064] Specifically, the controller calculates the initial address of the light points based on the acquired initial address image. It determines the on / off state of the light points by the pixel values at the position coordinates of each light point in the bit image, and then obtains the initial address of the light points based on the on / off state. Therefore, before calculating the initial address of each light point according to the acquired initial address image, the controller also needs to obtain the position coordinates of each light point. The specific calculation process of the initial address of the light points is as follows: The controller receives the bit address picture captured by the camera. According to the previously calculated position coordinates of the light points, at each position coordinate of the light points, it calculates the sum of the pixel points of m rows * n columns of the bit address picture to obtain the second pixel value, and compares the second pixel value with the second preset pixel value. If the second pixel value is greater than the second preset pixel value, it means that the light point at that position is in the on state, otherwise it is in the off state. On represents that the bit address is 1, and off represents that the bit address is 0. According to this calculation method, it calculates the bit addresses of the light points in all bit address pictures, and finally can obtain all the initial bit addresses of all the light points.
[0065] In some embodiments, the steps for the controller to output an address matching instruction to control each light point to output its own address through two states of on and off include:
[0066] S110. The controller outputs the lowest bit address matching instruction to the light point. The light point matches the lowest bit of its own address with the address in the address field of the lowest bit address matching instruction. If both are high level or low level, the light is on, otherwise the light is off;
[0067] S120. Obtain the lighting state image, and obtain the lowest bit address of each light point according to the lighting state image;
[0068] S130. Repeat the above steps until all the bit addresses of each light point are traversed.
[0069] Specifically, the light point outputs each bit address of the initial address bit by bit through the address matching instruction output by the controller. The specific process is as follows: The controller sends the lowest bit address matching instruction. The light point matches the lowest bit of its own address with the address in the address field of the command. If both are high level, the light is on, otherwise the light is off. According to the need, it can also be that the light is on when the level is low and the light is off when the level is high; then after the camera takes a picture, it sends the picture data to the controller, and the controller calculates the lowest bit address of all the light points in the system according to the calculation method of calculating the position coordinates of the light points; 3) Repeat the above process until all the bit addresses of the light points are traversed.
[0070] For example, assume that the light point has an 8-bit address, and the initial address of one of the light points is: 8’b1100_1001. The lowest-bit address matching instruction sent by the controller is 8’b0000_0001. The lowest bit of the initial address and the lowest bit of the address field of the address matching instruction are both high, so this light point is lit. The second lowest-bit address matching instruction is 8’b0000_0010, and this light point is turned off, until the highest-bit address matching instruction 8’b1000_0000, at which point this light point is lit. Therefore, the states of this light point from the lowest bit to the highest bit are: lit, off, off, lit, off, off, lit, lit. The camera can calculate the corresponding light point address code as 8’b1100_1001 based on the lit and off states of the 8 corresponding captured photos, and this address is the initial address of this light point.
[0071] It should be noted that when the camera captures the image of all the light points being lit and the bit address image of the initial address, both the light points and the camera should be maintained in fixed positions without changing their relative position relationship, otherwise it will cause the initial address calculation to be incorrect or make the initial address calculation more complex.
[0072] In some embodiments, the present invention also provides an LED light point address acquisition device, which includes a controller, an imaging device, and several light points. The controller is respectively connected to the imaging device and the light points. The controller includes a single-chip microcomputer (MCU), and the single-chip microcomputer includes a memory and a processor. The memory stores a computer program, and when the computer program is executed by the processor, it is used to implement the following steps:
[0073] S100: The controller outputs an address matching instruction to control each light point to output its own address through two states of lit and off; specifically as described in the embodiment of an LED light point address acquisition method, which will not be elaborated here.
[0074] S200: The controller controls the imaging device to acquire the initial address image of each light point in two states of lit and off; specifically as described in the embodiment of an LED light point address acquisition method, which will not be elaborated here.
[0075] S300: The controller obtains the initial address of each light point according to the initial address image; specifically as described in the embodiment of an LED light point address acquisition method, which will not be elaborated here.
[0076] In the above technical solution, the present invention controls each light point to output its own address in two states of on and off, and further obtains an initial address image by scanning all the light points with a camera, so that the initial addresses of each light point can be read according to the initial address image. Compared with the existing method of scanning one by one with a photodiode, it not only improves the efficiency of obtaining the light point address, but also reduces the false detection rate. In this way, the obtained initial addresses can be written into the reset addresses in parallel, which can not only greatly improve the production efficiency, but also improve the production yield.
[0077] In this embodiment, the imaging device may be a camera. The single-chip microcomputer calculates the image of the bit-by-bit light point address captured, obtains the initial address of the light point, and writes the reset address through this initial address. Considering the limitation of the computing resources of the single-chip microcomputer, the single-chip microcomputer can also upload the captured image to the computer through a serial port or a USB port. The Python on the computer calculates the initial address of the light point according to these images, and then sends these initial addresses to the single-chip microcomputer. The single-chip microcomputer then writes the reset address according to this initial address. The advantages of this method are: first, there are many publicly available image processing libraries in Python, and only a few functions need to be called to obtain the operation result; second, the computer has sufficient computing resources and fast computing speed; third, the library provides some algorithms to minimize the interference between light points, and the calculated initial address is more accurate and reliable.
[0078] In one implementation, the imaging device can use a mobile phone. The mobile phone calculates the image of the bit-by-bit light point address captured, obtains the initial address of the light point, and sends it to the controller through USB, Bluetooth or Wi-Fi, etc. The controller then writes the reset address according to this initial address, which can improve the computing speed.
[0079] In some embodiments, the present invention also provides a storage medium, on which a computer program is stored. When the computer program is executed by a processor, it is used to implement the following steps:
[0080] S100. The controller outputs an address matching instruction to control each light point to output its own address in two states of on and off; specifically as described in the embodiment of a method for obtaining an LED light point address, which will not be elaborated here.
[0081] S200. The controller controls the imaging device to obtain an initial address image of the on and off states of each light point; specifically as described in the embodiment of a method for obtaining an LED light point address, which will not be elaborated here.
[0082] S300. The controller obtains the initial addresses of each light point according to the initial address image. Specifically as described in the embodiment of a method for obtaining an LED light point address, which will not be elaborated here.
[0083] In summary, the LED light point address acquisition method, LED light point system and storage medium provided by the present invention have the following beneficial effects:
[0084] By controlling each light point to output its own address in two states, on or off, and further scanning all the light points through a camera to obtain an initial address image, the initial address of each light point can be read according to the initial address image. Compared with the existing method of scanning one by one using photosensitive diodes, it not only improves the efficiency of obtaining the light point address, but also reduces the false detection rate. In this way, the obtained initial address can be written into the reset address in parallel, which can not only greatly improve production efficiency, but also improve production yield.
