in S103, all the standard images in the standard image library conform to the detection standard, and for the first actual image, the first standard image is the detection standard of the first actual image. The first similarity between the first actual image and the first standard image meets the set condition, which indicates that the first actual image meets the test standard, indicates that the result obtained after the display device executes the first set instruction meets the expectation, further indicates that the display device successfully executes the first set instruction, and further indicates that various signals are smoothly transmitted in the display device, and hardware related to the first set instruction normally works.
by adopting the technical scheme to detect the display equipment, the labor intensity of testers can be reduced. In addition, in the process of testing the display device, the situation of inattention always occurs to the tester, and more or less misjudgment occurs.
in an alternative embodiment, as shown in fig. 2, the determining that the first similarity between the first actual image and the first standard image in the acquired standard image library satisfies the set condition includes:
S201, acquiring a first similarity according to color histograms of the first actual image and the first standard image, wherein the color histograms include one or more of a histogram of a red channel, a histogram of a green channel, a histogram of a blue channel and a gray level histogram.

in an optional implementation manner, when a first similarity is obtained, a first set similarity is correspondingly set, and if the first similarity is greater than the first set similarity, it is determined that the first similarity satisfies the set condition.
In an optional implementation manner, when two first similarities are obtained, two first set similarities are correspondingly set, and if both the two first similarities are greater than the two corresponding first set similarities, it is determined that the first similarities satisfy the set condition. For example, when the two first similarities include a similarity of a red channel histogram and a similarity of a green channel histogram, the first set similarity includes a set similarity of the red channel histogram and a set similarity of the green channel histogram, and if the similarity of the red channel histogram is greater than the set similarity of the red channel histogram and the similarity of the green channel histogram is greater than the set similarity of the green channel histogram at the same time, it is determined that the first similarity satisfies the setting condition.
In an optional implementation manner, when three first similarities are obtained, correspondingly, three first set similarities are set, and if all the three first similarities are greater than the corresponding three first set similarities, it is determined that the first similarities satisfy the set condition.
in an optional implementation manner, when four first similarities are obtained, correspondingly, four first set similarities are set, and if the four first similarities are all greater than the corresponding four first set similarities, it is determined that the first similarities satisfy the set condition.
in this embodiment, the first similarity between the first actual image and the first standard image can be quickly obtained, so as to determine whether the first actual image meets the set condition.
In a specific embodiment, as shown in fig. 3, the determining that the first similarity between the first actual image and the first standard image in the acquired standard image library satisfies the setting condition includes:
s301, reading a first actual image A;
S302, acquiring a red channel histogram A.R histogram of the first actual image A, acquiring a green channel histogram A.G histogram of the first actual image A, and acquiring a blue channel histogram A.B histogram of the first actual image A;
S303, converting the first actual image A into a gray mode to obtain a gray histogram A.GRAY histogram of the first actual image A;
s304, reading a first standard image B;
S305, acquiring a red channel histogram B.R histogram of the first standard image B, acquiring a green channel histogram B.G histogram of the first standard image B, and acquiring a blue channel histogram B.B histogram of the first standard image B;
S306, converting the first standard image B into a gray mode, and acquiring a gray histogram B.GRAY histogram of the first standard image B;
the steps are used for acquiring a color histogram of a first actual image and acquiring a color histogram of a first standard image;
S307, acquiring A.R histograms and a first similarity ABR of the B.R histograms, acquiring A.G histograms and a first similarity ABG of the B.G histograms, acquiring A.B histograms and a first similarity ABB of the B.B histograms, and acquiring a first similarity ABGRAY of the A.GRAY histograms and the B.GRAY histograms;
in S307, four first similarities may be acquired: a first similarity ABR, a first similarity ABG, a first similarity ABB and a first similarity ABGRAY;
s308, judging whether the first similarity ABR, the first similarity ABG, the first similarity ABB and the first similarity ABGRAY are simultaneously greater than a first set similarity corresponding to the first similarity ABR, the first similarity ABG, the first similarity ABGRAY or not; if yes, executing S309, otherwise executing S310;
That is, in S309, it is determined whether the following four conditions are simultaneously satisfied: the first similarity ABR is greater than a first set similarity ABR, the first similarity ABG is greater than a first set similarity ABG, the first similarity ABB is greater than a first set similarity ABB, and the first similarity ABGRAY is greater than the first set similarity ABGRAY;
S309, determining that the first similarity meets a set condition;
and S310, determining that the first similarity does not meet the set condition.
In some optional embodiments, the step S202 of determining whether the first similarity satisfies the set condition according to the first similarity and the first set similarity may be implemented as:
Acquiring a cosine value between a first vector and a second vector, and judging whether the first similarity meets a set condition or not according to the cosine value and a set cosine value, wherein the first vector takes two or more first similarities as vector coordinates, and the second vector takes two or more first set similarities as vector coordinates;
If the cosine value is larger than or equal to the set cosine value, the first similarity meets the set condition, and if the cosine value is smaller than the set cosine value, the first similarity does not meet the set condition.
In the technical scheme, whether the first similarity meets the set condition or not can be accurately judged. For example, the first similarity a1 of the red channel histogram, the first similarity a2 of the green channel histogram, and the first similarity a3 of the gray histogram between the third actual image and the third standard image are acquired, and then the first vector a is (a1, a2, a 3); correspondingly, the first set similarity of the red channel histogram is b1, the first set similarity of the green channel histogram is b2, and the first set similarity of the gray histogram is b3, then the second vector b is (b1, b2, b3), the cosine values of the first vector a and the second vector b are cos θ, the larger the value of cos θ, the higher the degree of similarity between the third actual image and the third standard image, and the smaller the value of cos θ, the lower the degree of similarity between the third actual image and the third standard image. If the process of acquiring the third actual image is disturbed, the first vector becomes a' ═ δ × a ═ (δ × a1, δ × a2, δ × a3), where δ is a constant. At this time, if the first similarity is directly compared with the first set similarity to determine whether the first similarity satisfies the set condition, it is obvious that the change of the first vector a affects the determination result. And judging whether the first similarity meets the set condition by using the cosine values cos theta of the first vector a 'and the second vector b, wherein even if the first vector is changed from a to a', the angle between the first vector and the second vector is unchanged, and the judgment result is not influenced. Therefore, under the condition that certain interference exists, the technical scheme can still accurately judge whether the first similarity meets the set condition.
In fig. 4, in an alternative embodiment, the step of obtaining a library of standard images comprises:
s401, saving a second setting instruction executed by the display device.
The second setting instruction is a second setting instruction input by the user. S401 needs to be executed for a plurality of times, each time S401 is executed, a second setting instruction executed by one display device is saved, and the test represented by the first setting instruction saved each time is different. After being executed several times in S401, the saved several second setting instructions form a setting instruction sequence. Optionally, the set instruction sequence is saved in the form of a script.
when a user normally uses the display equipment, a certain sequence is formed between the two set instructions, for example, when the display equipment is a television, the television must be muted first, and then the muting can be cancelled; in the process of operating the television menu, the first-level menu must be accessed first, and the second-level menu can be accessed on the basis of the first-level menu. When a user normally uses the display device, the same operation has different functions in different application scenes, for example, when a television plays a video, a certain operation can reduce the volume, and when the television calls a menu, the operation can control the movement of a cursor. In view of this, the tester needs to input the second setting instruction to the display device in sequence, and correspondingly, the display device stores the second setting instruction in sequence, that is, the setting instructions in the setting instruction sequence are arranged according to the setting sequence.
Correspondingly, in S101, sending the first setting instruction that is not executed in the setting instruction sequence to the display device may be implemented as: and sending the first setting instruction which is not executed in the setting instruction sequence to the display equipment according to the setting sequence.
S402, when the display device correctly executes a second setting instruction, saving a second standard image displayed by the display device, wherein the second setting instruction is associated with the second standard image.
the display device correctly executes the second setting instruction, which means that the display device displays an expected image after the display device executes the second setting instruction. Whether the image displayed by the display device is an expected image or not needs to be judged by a tester. And if the expected image is not displayed after the display equipment executes the second setting instruction, the image is not saved. The tester or the display equipment is replaced to obtain a second standard image which corresponds to a second set instruction and meets the expectation; or debugging the equipment to acquire a second standard image corresponding to the second setting instruction and meeting the expectation. The standard images in the standard image library are arranged according to the setting sequence corresponding to the setting instructions in the setting instruction sequence. The second setting instruction is associated with the second standard image, which means that the setting instruction corresponds to the standard image one by one, so that in the test process, after the first actual image displayed after the display equipment executes the first setting instruction is obtained, the correct first standard image can be obtained.
In this embodiment, it is only necessary to ensure that the second setting instruction corresponds to the second standard image one to one. In an alternative embodiment, the order of acquiring the library of standard images comprises: and saving a setting instruction executed by the display device, and saving a standard image displayed by the display device after the display device correctly executes the setting instruction. That is, S401 is executed once, while S402 is executed once.
In an alternative embodiment, the order of acquiring the library of standard images comprises: and saving the setting instruction sequence executed by the display equipment, and saving the standard image corresponding to one setting instruction displayed by the display equipment after the display equipment executes the setting instruction in the setting execution sequence. I.e. S401 is performed several times first, and S402 is performed several times.
the technical scheme provides a test standard for an actual test process, namely, whether the display equipment passes the test represented by a certain set command or not needs to use the second standard image as a detection standard. In addition, in this embodiment, the tester may save the second setting instruction and the second standard image corresponding to the display device according to different display devices, and form a setting instruction sequence and a standard image library dedicated to the display device. Namely, different display devices can be tested by the testing method only by providing different set instruction sequences and different standard image libraries, so that the testing method is wider in application range.
in an alternative embodiment, sending the first setting instruction that is not executed in the setting instruction sequence to the display device may be implemented as: and directly sending the first setting instruction to the display equipment in a network communication mode.
In an optional implementation manner, the acquiring of the first actual image displayed after the display device executes the first setting instruction may be implemented as: and acquiring a first actual image displayed after the display equipment executes a first setting instruction in a software screenshot mode.
For example, when a display of a computer is tested, a first actual image displayed after the display executes a first setting instruction can be acquired through screenshot software.
Corresponding to the above two ways, in some alternative embodiments, a hardware block diagram as shown in fig. 5 is used to test the display device, where the testing apparatus 20 is used to execute the testing method, the testing apparatus 20 is connected to the display device 10 through the router 60, the signal generating apparatus 50 is connected to the display device 10, and the display device 10 can display the image signal sent by the signal generating apparatus 50, such as an ATV signal, a DTV signal, a CVBS signal, a YUV signal, an HDMI signal, and the like. Alternatively, the signal generating device 50 sends standard signals, such as standard images of 525 circles, 625 circles, 32 gray scales, 16 gray scales, color bars, color cards, and the like. The accuracy of the test can be increased. The testing apparatus 50 sends a first setting instruction to the display device 10 through the router 60, and the testing apparatus 20 further obtains a first actual image displayed after the display device 10 executes the first setting instruction through the router 60.
in a preferred embodiment, the first setting instruction that is not executed in the setting instruction sequence is sent to the display device, specifically: sending the first setting instruction to the display equipment through a matched input device of the display equipment;
The method includes the steps of acquiring a first actual image displayed after a display device executes a first setting instruction, specifically: a first actual image is acquired by the camera device.
In the embodiment, the manual operation of a tester can be simulated more truly, the interference of other signals to the display equipment can be avoided, and the test work on the display equipment can be completed more accurately. As for the input device associated with the display device, for example, a television is taken as an example, and if the television receives an operation command transmitted from a remote controller through an infrared receiving device, the input device associated with the television is an infrared receiving device. Compared with the method that the first setting instruction is sent to the display device through the debugging interface, if the first similarity between the first actual image and the first standard image meets the setting condition, the method that the first setting instruction is sent to the display device through the matched input device of the display device is adopted, and meanwhile, the matched input device of the display device can work normally is indicated. Therefore, the present embodiment can complete the testing work of the display device more comprehensively.
in some optional embodiments, the display device is tested by using a hardware block diagram shown in fig. 6, the signal generating device 50 provides an image signal for the display device 10, the testing device 20 is used for executing the testing method, and the testing device 20 can send a setting instruction to the display device 10 through the input device 30. In the process of sending the setting instruction, taking a television as an example, the input device 30 is an infrared receiving device, correspondingly, the output end of the testing device 20 may be connected to the input end of an infrared emitting device (not shown in the figure), the testing device 20 sends the setting instruction to the infrared emitting device in the form of an electrical signal, the infrared emitting device converts the setting instruction in the form of the electrical signal into the setting instruction in the form of an infrared signal, and then sends the setting instruction in the form of the infrared signal to the input device 30, the input device converts the received setting instruction in the form of the infrared into the setting instruction in the form of an electrical signal, and the display device 10 executes a corresponding action according to the setting instruction in the form of the electrical signal. Thereby enabling the first setting instruction to be transmitted to the display apparatus 10 through the companion input device 30 of the display apparatus 10. In fig. 6, the image pickup device 40 may acquire an actual image displayed by the display apparatus 10 and transmit the actual image to the test device 20.
In an alternative embodiment, as shown in fig. 7, when the display device is a tv, the testing method of the display device may be implemented as follows:
