Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for correcting data processing, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system, such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than presented herein.
Fig. 1 is a flowchart of a correction data processing method according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, acquiring correction data of a non-rectangular module, wherein the arrangement format of the correction data is a non-rectangular array;
step S104, determining a correction data matrix template corresponding to the non-rectangular module based on the non-rectangular array, wherein the correction data matrix template comprises the non-rectangular array;
step S106, based on the position corresponding relation between the non-rectangular module and the correction data matrix template, writing the correction data into the correction data matrix template to obtain a correction data file, wherein the correction data matrix template comprises: the effective correction data correspond to the correction data of the channels corresponding to the lamp beads in the non-rectangular module, and the point-supplementing correction data are data without the channels corresponding to the lamp beads in the non-rectangular module;
and step S108, correcting the non-rectangular module based on the correction data file.
Through the steps, the correction data of the non-rectangular module is obtained, the correction data matrix template corresponding to the non-rectangular module is determined according to the non-rectangular array corresponding to the correction data, the correction data is written into the correction data matrix template based on the position corresponding relation between the non-rectangular module and the correction data matrix template, a correction data file can be obtained, finally, the non-rectangular module can be corrected according to the correction data file, the positions of the corrected data matrix template, which do not have channels corresponding to the lamp beads in the non-rectangular module, are supplemented with point-supplementing correction data, so that the correction of irregular non-rectangular modules can adopt a normal correction data matrix template to carry out correction processing, the point-correcting data is invalid, i.e. does not work, because the point-correcting data does not correspond to the lamp bead in the non-rectangular module. Consequently, realized directly, carried out the technological effect of rectifying to various types of non-rectangular module fast effectively, and then solved the technical problem that the correction work to non-rectangular module is loaded down with trivial details, inefficiency.
As an alternative embodiment, the "correction data matrix template includes a non-rectangular array" may refer to that the size of the correction data matrix template is not smaller than the size of the non-rectangular array, i.e. the number of rows and columns of the correction data matrix template is not smaller than the number of rows and columns of the non-rectangular array.
As an alternative embodiment, when determining the correction data matrix template corresponding to the non-rectangular module based on the non-rectangular array, various manners may be adopted, for example, the following manners may be adopted: determining the longest row number and the longest column number corresponding to the non-rectangular array; and determining a correction data matrix template corresponding to the non-rectangular module based on the longest row number and the longest column number. By determining the longest row number and the longest column number corresponding to the non-rectangular array, the non-rectangular module can be normalized in a rectangular array with the longest row number as the width and the longest column number as the length, that is, a correction data matrix template corresponding to the non-rectangular module is determined, so that the non-rectangular module can be corrected conveniently. It should be noted that, when determining the correction data matrix template corresponding to the non-rectangular module based on the longest row number and the longest column number, the longest row number and the longest column number are the minimum size of the correction data matrix template, and the size of the finally determined correction data matrix template may be larger than the minimum size, that is, as long as the correction data matrix template can contain the non-rectangular module.
As an optional embodiment, when the correction data is written into the correction data matrix template based on the position corresponding relationship between the non-rectangular module and the correction data matrix template to obtain the correction data file, various manners may be adopted, for example, the following manners may be adopted: under the condition that the rows and the columns of the correction data matrix template respectively correspond to the longest row number and the longest column number corresponding to the non-rectangular array, the correction data at the first row and column positions in the non-rectangular array are respectively written into the second row and column positions in the correction data matrix template as effective correction data, wherein the first row and column positions and the second row and column positions are the same row and column positions; acquiring point compensation correction data; and writing the dot-padding correction data into other positions except the row and column positions with valid correction data in the correction data matrix template to obtain a correction data file. After the correction data matrix template is determined, each position point in the non-rectangular array and each position point in the correction data matrix template are in one-to-one correspondence by using the rows and the columns according to the correction data matrix template. For example, a non-rectangular array having a bead at the third column of the second row in the correction data matrix template sized array would be written with valid correction data corresponding to the third column of the second row of the correction data matrix template, while a non-rectangular array having no bead at the fifth column of the fourth row in the correction data matrix template sized array would be written with padding correction data corresponding to the fifth column of the fourth row of the correction data matrix template. Therefore, the non-rectangular array can completely correspond to the array template of one rectangle, and the point-compensating correction data can not process the non-rectangular array due to the introduction of the point-compensating correction data, so that the correction effect can not be influenced by the adoption of the matrix template of the non-rectangular array.
As an alternative embodiment, when acquiring the dot correction data, various manners may be adopted, for example, the following manners may be adopted: determining a size range of the supplementary point data based on the correction data; and generating the supplementary point correction data within the size range of the supplementary point data. After determining which row and column positions are written with valid correction data, the remaining row and column positions can be determined from the correction data. And writing supplementary point correction data in the rest row-column positions, wherein the specific value of the supplementary point correction data can be determined according to the correction data, namely the value range of the effective correction data. For example, the size range of the dot-padding data can be determined according to the valid correction data, so that the written dot-padding correction data meet a certain writing requirement and conform to the range of the correction data of the non-rectangular module.
As an alternative embodiment, when performing correction processing on a non-rectangular module based on a correction data file, various manners may be adopted, for example, the following manners may be adopted: determining the same type of modules which are the same as the non-rectangular modules; and carrying out batch correction processing on the non-rectangular modules and the models of the same type based on the correction data file. After the correction data matrix template corresponding to the non-rectangular module is determined, because the module types are the same, and the corresponding correction data matrix templates are also the same, the modules of the same type as the non-rectangular module can be subjected to batch processing by using the same correction data matrix template, and the efficiency of correction work is improved to the maximum extent. It should be noted that the batch processing may be implemented as an option, for example, the batch correction processing may be performed on the non-rectangular modules of the same type only when the batch processing instruction is received.
As an alternative embodiment, the non-rectangular module may be a module of a target spherical screen. By corresponding the non-rectangular module to the module of the target spherical screen, the correction of the target spherical screen can be completed quickly and efficiently by the method. In addition, the correction data matrix template is specific to all the non-rectangular modules included in the target spherical screen, that is, only one correction data matrix template needs to be determined in one target spherical screen to correct all the non-rectangular modules included in the target spherical screen. In this alternative embodiment, the determined row and column of the correction data matrix template may be the row and column of the non-rectangular module corresponding to the longest row and column of all non-rectangular modules, thereby ensuring that the determined correction data matrix template may contain any non-rectangular module of all non-rectangular models of the target spherical screen. It should be noted that the target spherical screen is only an example, and other irregular-shaped screens may also be applied to the present application.
As an alternative embodiment, when performing correction processing on a non-rectangular module based on a correction data file, various manners may be adopted, for example, the following manners may be adopted: writing the correction data file into a synchronous dynamic random access memory SDRAM; and performing brightness and chromaticity compensation processing on the lamp beads in the non-rectangular module by reading a correction data file in the SDRAM. When the non-rectangular module is corrected based on the correction data file, the correction data file can be stored through the steps, the lamp beads in the non-rectangular module are subjected to accurate brightness and chromaticity compensation processing by reading the correction data file in the SDRAM, the stored correction data file can be directly used when the same non-rectangular module needs to be corrected again later, and the correction data file can also be applied to the correction of the module with the same type as the non-rectangular module corresponding to the correction data file, so that the trouble that the correction data file needs to be acquired again during each correction is omitted, and the correction work efficiency is improved.
Based on the above embodiment and the alternative embodiment, the present invention provides an alternative implementation, and the following description takes an LED spherical screen as an example.
The LED display screen has gained common application due to its characteristics of high brightness, wide visual range, long service life, large area, easy computer interface, rich support software, etc. At present, most of LED display screens are flat screens, a plurality of held LED modules are spliced into a box body, and then the LED box bodies are spliced into the flat display screen. The LED display screen is widely applied to the fields of outdoor advertising, stage background, data visualization and the like, but the application field of the LED display screen also provides wider requirements, the spherical screen can enable audiences to watch at 360-degree visual angles, spherical objects such as the earth and football can be directly displayed on the LED spherical display screen, visual and perfect video enjoyment is given to people, and the LED display screen can be applied to places such as science and technology museum exhibition, pilot flight simulation and the like.
For the correction of the LED flat panel, a point-by-point brightness compensation correction method is usually adopted to solve the problem of poor consistency of the display brightness and the chromaticity of the LED flat panel, and the correction data information of each pixel point corresponds to the brightness compensation of the R, G, B lamps of the pixel point. The LED spherical screen and the LED flat screen are different in module design structure, modules forming the LED flat screen are all rectangles with the same size, the inner lamp beads are arranged consistently and are all rectangular arrays, correction data obtained through correction of a correction camera are all effective data and correspond to module pixel points one to one, the correction data of each module are all the rectangular arrays arranged consistently, when an instruction of burning the correction data is reached, a computer stores the correction data in SDRAM (synchronous dynamic random access memory) of the module, the brightness of a R, G, B lamp when each pixel point of the module displays R, G, B pictures is changed, and finally the brightness and the chromaticity displayed by the module are enabled to have good consistency.
However, the correction method is not suitable for the LED spherical screen, the types of modules forming the LED spherical screen are various, the modules are generally designed to be non-rectangular, the quantity of the lamp beads in each row and each column on the same module may be different, and the data arrangement formats of the correction cameras corrected by the different types of modules are different and are non-rectangular arrays. At present, the one-to-one correspondence of each pixel point of a multi-type LED spherical screen module with correction data is very difficult, and the correction data arrangement format of a plurality of templates is needed, so that the correction work is very complicated.
In view of the above problem, an optional embodiment of the present invention provides a method for correcting data padding to implement correction data processing of an LED spherical screen, where the method includes the following steps:
(1) the method comprises the steps of firstly obtaining the longest line number and the longest line number of all module pixel points of the LED spherical screen, and making a pixel point arrangement matrix chart (namely the correction data matrix template) according to the line number and the line number, wherein the line number and the line number of the pixel points in the rectangular chart are not smaller than the longest line number and the longest line number of the module pixel points respectively, and the matrix chart is the correction data arrangement format of all modules. It should be noted that the module is a non-rectangular module (e.g., may be a trapezoidal module).
(2) And performing correction data point supplementing processing on each type of module of the LED spherical screen, and confirming effective correction data and point supplementing correction data of each type of module in a pixel point arrangement matrix diagram.
The effective correction data is data of channels corresponding to the beads in the SDRAM, namely each effective correction data can correctly perform brightness compensation on the corresponding bead, the number of the effective correction data is equal to the number of pixel points of each module of the type, and the number of the effective correction data in each row is equal to the number of corresponding rows and columns of the pixel points of each module of the type.
The point-supplementing correction data is data of the SDRAM without channels corresponding to the lamp beads, other correction data except the effective correction data in the correction data matrix template are point-supplementing correction data, the size of each point-supplementing correction data is within the size range supported by the effective correction data and can be normally stored in the SDRAM, and when the point-supplementing data is written in the SDRAM, no lamp beads corresponding to the point-supplementing correction data exist, so that the correction effect of the module is not influenced.
(3) And setting the address of each spherical LED screen module, and determining all the addresses of the modules of the same type as the same correction data template.
After point-by-point brightness compensation correction is carried out on the LED spherical screen through the correction camera to obtain correction data, a box address is selected to write in the correction data, the computer preferentially determines the address of the internal box module according to the box address, a correction data matrix diagram template of each module is determined, a correction data point supplementing command is carried out in a correction data file corresponding to the module, point supplementing correction data is filled, and a new correction data file is generated. And then writing the correction data file into the SDRAM of each module in the box body.
The effective correction data, namely the data obtained by correcting the camera, are provided with channels corresponding to the lamp beads, so that the brightness and chromaticity compensation can be correctly carried out on all the lamp beads in the module, and the point-supplementing correction data is not provided with channels corresponding to the lamp beads, so that the correction effect of the LED spherical screen cannot be influenced.
