The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in FIG. 1 does not constitute a limitation of the image detection apparatus, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, the memory 1005, which is a storage medium, may include an operating system, a network communication module, a user interface module, and a picture quality detection program.
In the image quality detection apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the image quality detection apparatus according to the present invention may be provided in the image quality detection apparatus, and the image quality detection apparatus calls the image quality detection program stored in the memory 1005 through the processor 1001 and executes the image quality detection method according to the embodiment of the present invention.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of an image quality detection method according to the present invention.
In this embodiment, the image quality detection method includes the following steps:
and step S10, inputting the same image quality display signal into the device to be detected and the standard image quality display device respectively.
Specifically, the execution subject of the present embodiment is the image quality detection apparatus that establishes communication connection with the apparatus to be detected and the standard image quality display apparatus in advance.
It should be understood that, in practical applications, the aforementioned image quality detection device may be any device capable of executing the image quality detection method provided by the present embodiment, such as a personal computer, a tablet computer, a smart phone, and the like, which are not listed here, and are not limited thereto.
In addition, in practical application, when establishing communication connection between the device to be detected and the standard image quality display device and the image quality detection device, a Low-Voltage Differential Signaling (LVDS) interface with a noise reduction function that is arranged in the devices may be specifically adopted, and other self-contained or external signal acquisition interfaces may also be adopted, which is not limited in this embodiment.
And step S20, collecting the image quality display signal currently displayed by the equipment to be detected to obtain the image quality display signal to be detected.
And step S30, acquiring the image quality display signal currently displayed by the standard image quality display equipment to obtain the standard image quality display signal.
Specifically, the obtained to-be-detected image quality display signal is the image quality display signal input to the to-be-detected device in step S10.
Accordingly, the standard image quality display signal is the image quality display signal input by the standard image quality display device in step S10.
In addition, it is worth mentioning that, in practical applications, in order to ensure the accuracy of the subsequent detection result, the acquired to-be-detected image quality display signal and the standard image quality display signal need to be the same frame of image.
It should be understood that the same frame of image in this embodiment specifically refers to an image corresponding to the same frame of data of the same streaming media resource displayed in the display screens of the device to be detected and the standard image quality display device at the current time, that is, when the detection operation is performed, the display signals displayed in the device to be detected and the standard image quality display device are the same display signal input at the same time.
In addition, the standard image quality display device may be predetermined by a technician according to an existing detection method, or may be determined by learning analysis of a large number of existing images based on a machine learning algorithm, which is not limited herein.
In addition, the determination standard of the standard image quality display device may be specifically determined according to the image quality requirement that needs to be met by the specified device to be detected, which is not limited in this embodiment.
In addition, it is worth mentioning that in practical applications, there may be a plurality of devices to be detected that are in communication connection with the image quality detection device in advance, that is, when the image quality detection instruction is received, the image quality display signal to be detected currently displayed by the plurality of devices to be detected may be acquired at the same time.
Step S40, respectively converting the to-be-detected image quality display signal and the standard image quality display signal according to a preset conversion rule, so as to obtain a to-be-detected image quality color data table corresponding to the to-be-detected image quality display signal and a standard image quality color data table corresponding to the standard image quality display signal.
Specifically, in this embodiment, the conversion rule is a binary conversion rule.
In addition, since in practical applications, the programming that can be generally recognized by the computer device is hexadecimal, in the present embodiment, the preset binary conversion rule is preferably a hexadecimal conversion rule. However, in a specific implementation, a person skilled in the art may select other binary rules, such as binary, octal, etc., for performing subsequent conversion between the image display signal to be detected and the standard image display signal according to needs, which are not listed here one by one, and no limitation is made to this.
In addition, in order to facilitate subsequent comparison operations, each comparison operation is performed on the color data in the to-be-detected image quality color data table and the color data in the standard image quality color data table converted from the display signal corresponding to the same frame of image, so as to ensure the validity of the comparison result, before the step S40 is executed, the to-be-detected image quality display signal and the standard image quality display signal may be numbered, and after the numbering is completed, the to-be-detected image quality display signal and the standard image quality display signal after the numbering are respectively subjected to binary conversion according to a preset binary conversion rule, such as a hexadecimal conversion rule.
In order to achieve the above object, it is necessary to satisfy that the numbers of the to-be-detected picture quality display signal and the standard picture quality display signal corresponding to the same frame image correspond to each other when numbering.
For example, when the same frame image corresponding to the collected to-be-detected quality display signal and the standard quality display signal is M1, the to-be-detected quality display signal may be numbered TM1, and the standard quality display signal may be numbered RM 1.
Accordingly, when the same frame image corresponding to the collected to-be-detected quality display signal and the standard quality display signal is M2, the number of the to-be-detected quality display signal may be TM2, and the number of the standard quality display signal may be RM 12.
It should be understood that the above is only an example, and the technical solution of the present invention is not limited at all, and in practical applications, a person skilled in the art may set different identification numbers for the to-be-detected image quality display signal and the standard image quality display signal according to needs, and perform numbering according to the set identification numbers, which is not limited herein.
In addition, in order to facilitate understanding of the operations in step S40 after numbering, in the present embodiment, the binary conversion rule is hexadecimal, and step S40 is subdivided into five steps of sub-step S401 to sub-step S405, which are described as follows:
and a substep S401 of determining the numbered pixels of the same frame of image corresponding to the to-be-detected image quality display signal and the standard image quality display signal, respectively, to obtain a to-be-detected image quality pixel point distribution table and a standard image quality pixel point distribution table.
For example, when the same frame image M1 corresponding to the to-be-detected image quality display signal TM1 and the standard image quality display signal RM1 is composed of 255 × 255 pixels, the obtained to-be-detected image quality pixel point distribution table is a pixel point distribution table composed of 255 rows and 255 columns, and each cell in the pixel point distribution table is a pixel point.
Correspondingly, the obtained standard image quality pixel point distribution table is also a pixel point distribution table consisting of 255 rows and 255 columns, and each lattice in the pixel point distribution table is a pixel point.
In addition, it should be understood that, since the to-be-detected image quality display signal and the standard image quality display signal correspond to the same frame image, two pixels determined according to the same abscissa and the same ordinate in the obtained to-be-detected image quality pixel point distribution table and the standard image quality pixel point distribution table are the same under normal conditions, that is, if they are different, it can be considered that there is an abnormality.
And a substep S402 of traversing the pixels in the distribution table of the pixels of the image quality to be detected, and performing hexadecimal conversion on the traversed pixels of the image quality to be detected according to a preset hexadecimal conversion rule to obtain hexadecimal color data of the pixels of the image quality to be detected, corresponding to the pixels of the image quality to be detected.
Specifically, because the conversion between any arbitrary systems is mature at present, and the embodiment does not involve the improvement of the system conversion process when performing the system conversion on the pixel point, no matter the hexadecimal system or other systems are used as the system conversion rules, when implementing the above operation, a person skilled in the art can directly implement the operation by using the existing system conversion method, and details are not described here.
And a substep S403, sequentially recording the obtained hexadecimal color data of the pixels of the to-be-detected image quality, and obtaining a to-be-detected image quality color data table corresponding to the to-be-detected image quality display signal.
Taking the distribution table of the image quality pixel points to be detected as one 255 × 255 pixel point distribution table as an example, after the processing of the substep S402 and the substep S403, the finally obtained color data table of the image quality to be detected is still one 255 × 255 table, that is, the table records the color data corresponding to the 255 × 255 pixel points, and the total number is 255 × 255.
And a substep S404 of traversing the pixels in the standard image quality pixel point distribution table, and performing hexadecimal conversion on the traversed standard image quality pixel points according to a preset hexadecimal conversion rule to obtain hexadecimal standard image quality pixel point color data corresponding to the standard image quality pixel points.
And a substep S405 of recording the hexadecimal standard image quality pixel point color data in sequence to obtain a standard image quality color data table corresponding to the standard image quality display signal.
Similarly, in practical application, the conversion and processing of the standard image quality pixel point distribution table are similar to those of the image quality pixel point distribution table to be detected, and are not repeated here.
Further, in order to facilitate the comparison of the color data performed in step S30, in this embodiment, the image quality color data table to be detected and the standard image quality color data table are preferably set as hexadecimal red, green and blue RGB color data tables, that is, the color data recorded in the image quality color data table to be detected and the color data recorded in the standard image quality color data table are both RGB data.
In order to facilitate understanding of the operation of sequentially recording the obtained hexadecimal color data of the to-be-detected image quality pixel point to obtain the to-be-detected image quality color data table corresponding to the to-be-detected image quality display signal, that is, the hexadecimal RGB color data table, the following is specifically described:
firstly, recording the obtained hexadecimal color data of the image quality pixel point to be detected in sequence to obtain an initial image quality color data table to be detected;
then, traversing the initial to-be-detected image quality color data table, and performing RGB conversion on traversed hexadecimal to-be-detected image quality pixel point color data according to a preset RGB data conversion rule to obtain to-be-detected image quality RGB data corresponding to the to-be-detected image quality pixel point color data;
and finally, recording the obtained RGB data of the picture quality to be detected in sequence to obtain a hexadecimal RGB color data table to be detected corresponding to the display signal of the picture quality to be detected, and taking the hexadecimal RGB color data table to be detected as the color data table of the picture quality to be detected.
In practical applications, the existing RGB conversion program may be specifically adopted, or a technician may recompile a suitable RGB conversion program according to needs and preset the RGB conversion program in the image quality detection device, so that the image quality detection device can execute the RGB conversion operation to complete the RGB conversion operation of the color data of the image quality pixel to be detected.
Correspondingly, the step of sequentially recording to obtain hexadecimal color data of the standard image quality pixel points to obtain a standard image quality color data table corresponding to the standard image quality display signal includes:
firstly, recording the obtained hexadecimal standard image quality pixel point color data in sequence to obtain an initial standard image quality color data table;
then, traversing the initial standard image quality color data table, and performing RGB conversion on the traversed hexadecimal standard image quality pixel point color data according to the RGB data conversion rule to obtain standard image quality RGB data corresponding to the standard image quality pixel point color data;
and finally, recording the obtained standard image quality RGB data in sequence to obtain a hexadecimal standard RGB color data table corresponding to the standard image quality display signal, and taking the hexadecimal standard RGB color data table as the standard image quality color data table.
It should be understood that the above is only a specific implementation manner, and the technical solution of the present invention is not limited in any way, and in practical applications, a person skilled in the art may select other manners as needed to implement the above operations, and is not limited herein.
Step S50 is to compare the color data described in the to-be-detected image quality color data table with the color data described in the standard image quality color data table, and generate an image quality detection report based on the comparison result.
Specifically, in this embodiment, it is preferable that the to-be-detected quality color data table and the standard quality color data table are converted into RGB data tables, and therefore the operation executed in step S30 specifically includes:
firstly, respectively traversing the to-be-detected image quality color data table and the standard image quality color data table, comparing the traversed to-be-detected image quality RGB data with the traversed standard image quality RGB data, and determining an offset value between the to-be-detected image quality RGB data and the standard image quality RGB data; then, the deviation values are recorded in sequence, and an image quality detection report is generated according to a preset allowable deviation range and the recorded deviation values.
Specifically, in order to facilitate a technician to locate an abnormal problem subsequently, in the image quality detection report in this embodiment, detection information of each pixel point in the same frame of image currently displayed by the device to be detected is recorded, where the detection information may specifically be abnormal information or normal information, and is not limited herein.
It should be understood that, in order to ensure the validity of the determined offset value, the traversed RGB data of the to-be-detected picture quality and the standard RGB data are specifically two pieces of RGB data determined according to the same abscissa and the same ordinate.
In addition, the allowable offset range may be specifically determined for a specification that needs to be met and is set by the device to be detected, for example, the allowable offset range is set to [ -5, 5], that is, if an offset value of the RGB data of the image to be detected corresponding to a certain pixel point in the color data table of the image to be detected with respect to the RGB data of the standard patient corresponding to the corresponding pixel point in the color data table of the standard image quality exceeds the allowable offset range, it may be determined that the pixel point is abnormal.
It is not difficult to find out through the above description that, in the image quality detection method provided in this embodiment, when performing image quality detection, the same image quality display signal is respectively input to the device to be detected and the standard image quality display device, then the image quality display signal to be detected currently displayed by the device to be detected and the standard image quality display signal currently displayed by the predetermined standard image quality display device, which are in communication connection with the image quality detection device, are respectively collected, and the collected image quality display signal to be detected and the standard image quality display signal are specified to be the same frame image, so that the accuracy of the subsequent detection result is ensured at the source.

It should be understood that the above is only an example, and the technical solution of the present invention is not limited in any way, and in practical applications, those skilled in the art can make settings according to needs, and the present invention is not limited herein.

It is not difficult to find out through the above description that, in the image quality detection method provided in this embodiment, after the image quality detection operation of the device to be detected is completed according to the currently displayed image of the same frame corresponding to the image quality display signal to be detected and the standard image quality display signal, and an image quality detection report is generated, whether the image quality of the device to be detected is abnormal or not is determined according to information recorded in the generated image quality detection report, and when it is determined that the image quality is abnormal, a pause play instruction is sent to the device to be detected and the standard image quality display device, so that the device to be detected and the standard image quality display device are controlled to stop playing the next frame of image, and the currently displayed image of the same frame. After the operation is completed, an abnormal pixel point marking instruction is sent to the equipment to be detected and the standard image quality display equipment, so that the equipment to be detected and the standard image quality display equipment respectively mark abnormal pixel points in the same frame of image displayed currently, and therefore technicians can more quickly and accurately locate and solve the abnormal problem according to detection results, and the detection process is more intelligent and efficient.
In addition, an embodiment of the present invention further provides a computer-readable storage medium, where an image quality detection program is stored, and when the image quality detection program is executed by a processor, the image quality detection method implements the steps of the image quality detection method described above.
Referring to fig. 4, fig. 4 is a block diagram illustrating a structure of the image quality detection apparatus according to the first embodiment of the present invention.

It should be noted that, in practical applications, in order to ensure the accuracy of the subsequent detection result, the acquired to-be-detected image quality display signal and the standard image quality display signal need to be the same frame of image.
It should be understood that the same frame of image in this embodiment specifically refers to an image corresponding to the same frame of data of the same streaming media resource displayed in the display screens of the device to be detected and the standard image quality display device at the current time, that is, when the detection operation is performed, the display signals displayed in the device to be detected and the standard image quality display device are the same display signal input at the same time.
Furthermore, in practical applications, in order to facilitate the subsequent contrast operation, each contrast operation is performed on the color data in the to-be-detected quality color data table and the standard quality color data table converted from the display signal corresponding to the same frame of image, thereby ensuring the validity of the comparison result, before the processing module 4004 performs the operation of converting the to-be-detected image quality display signal and the standard image quality display signal according to a preset conversion rule (specifically, a binary conversion rule), the to-be-detected image quality display signal and the standard image quality display signal may be numbered first, after the numbering is completed, the numbered image quality display signal to be detected and the numbered standard image quality display signal are respectively subjected to the binary conversion according to a preset binary conversion rule, such as a hexadecimal conversion rule.
In order to achieve the above object, it is necessary to satisfy that the numbers of the to-be-detected picture quality display signal and the standard picture quality display signal corresponding to the same frame image correspond to each other when numbering.
In addition, in order to facilitate understanding of the operation performed by the processing module 4004 after the numbering, the present embodiment takes the case that the binary conversion rule is hexadecimal, and the conversion operation performed by the processing module 4004 is specifically described as follows:
firstly, respectively determining pixel points of the same frame of image corresponding to the image quality display signal to be detected and the standard image quality display signal after numbering, and obtaining a distribution table of the pixel points of the image quality to be detected and a distribution table of the pixel points of the standard image quality;

In order to facilitate understanding of the operation of sequentially recording the obtained hexadecimal color data of the to-be-detected image quality pixel point to obtain the to-be-detected image quality color data table corresponding to the to-be-detected image quality display signal, that is, the hexadecimal RGB color data table, the following is specifically described:
firstly, recording the obtained hexadecimal color data of the image quality pixel point to be detected in sequence to obtain an initial image quality color data table to be detected;
then, traversing the initial to-be-detected image quality color data table, and performing RGB conversion on traversed hexadecimal to-be-detected image quality pixel point color data according to a preset RGB data conversion rule to obtain to-be-detected image quality RGB data corresponding to the to-be-detected image quality pixel point color data;
and finally, recording the obtained RGB data of the picture quality to be detected in sequence to obtain a hexadecimal RGB color data table to be detected corresponding to the display signal of the picture quality to be detected, and taking the hexadecimal RGB color data table to be detected as the color data table of the picture quality to be detected.
In practical applications, the existing RGB conversion program may be specifically adopted, or a technician may recompile a suitable RGB conversion program according to needs and preset the RGB conversion program in the image quality detection device, so that the image quality detection device can execute the RGB conversion operation to complete the RGB conversion operation of the color data of the image quality pixel to be detected.
Correspondingly, the step of sequentially recording to obtain hexadecimal color data of the standard image quality pixel points to obtain a standard image quality color data table corresponding to the standard image quality display signal includes:
