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 application.
In the related technology, the optical machine is tested by installing a script, so that the optical machine continuously runs for a specified time, a log is recorded in the running process, and after the running is finished, a worker copies the log through a system, manually analyzes the log, judges the error times and obtains the current test result.

Based on the above technical problem, the present embodiment provides a method for testing an optical device, specifically referring to fig. 1, where fig. 1 is a flowchart of the method for testing an optical device provided in the present embodiment, and the method specifically includes:
and S110, acquiring a multi-frame test image of a projection picture acquired by the camera.
In the embodiment, the projector performs projection, projects a projection picture in a projection area, and collects a plurality of frames of projection images including the projection picture by using the camera. The frame number is not limited in the embodiment, and the user can customize the setting. It can be understood that, the testing for the optical engine is generally performed periodically, that is, in a testing period, a plurality of tests are performed, and the present embodiment provides a description about one test in steps S110 to S130 to obtain a current testing result. In this embodiment, the projection picture is not limited, and the user can set the projection picture according to actual requirements.
And S120, performing image calculation on the multi-frame test image to obtain a current test result.
In this embodiment, image calculation is performed on multiple frames of test images to obtain a current test result, it can be understood that after the test is completed in the whole test period, image calculation is sequentially performed on multiple frames of test images of each test to obtain the current test result, or image calculation is performed on multiple frames of test images of the current test to obtain the current test result during the test period, and users can select the current test result according to actual requirements in the two modes. In this embodiment, the mode of image calculation is not limited, the brightness calculation may be performed on the test image, the definition calculation may also be performed, the corresponding current test result may be set according to the test requirement, and when the optical machine test method is to test the opening and closing of the optical machine door, the current test result includes the successful opening of the door and the failed opening of the door; when the optical machine testing method is an on-off test of the optical machine, the current testing result comprises successful lighting and failed lighting.
In an implementation manner, please refer to fig. 2, where fig. 2 is a schematic flowchart of a current test result obtaining process provided in an embodiment of the present application, and the process includes:
and S121a, performing brightness calculation on the test image to obtain a brightness value.
In this embodiment, the performing the luminance calculation on the test image may include: acquiring an initial brightness value of each pixel in a test image, calculating an image brightness average value of the test image according to the initial brightness value of each pixel in the test image, and taking the image brightness average value as a brightness value; or may include: converting the initial brightness value of each pixel in the test image into a logarithmic space to calculate the logarithmic space brightness average value of the test image; carrying out anti-log calculation on the logarithmic space brightness average value of the test image to obtain an image brightness average value of the test image, and taking the image brightness average value as a brightness value; or may include: acquiring reference images of a projection picture under different brightness values, matching the test image with the reference images in sequence, determining that the brightness value of the test image is consistent with the reference brightness value of the reference image successfully matched when the matching is successful, and taking the reference brightness value as the brightness value; of course, other calculation modes can be provided, and the user can customize the setting.
S122a, determining the average brightness value of the test images with continuous preset frame numbers according to the brightness value.
And selecting test images with continuous preset frame numbers from the multi-frame test images, and determining the average brightness value according to the brightness value. For example, the test images of consecutive preset frames include image a, image B, image C, image D, and image E, and the corresponding brightness values are a, B, C, D, and E in sequence, so that the average brightness value is (a + B + C + D + E)/5.
And S123a, determining the current test result according to the relation between the brightness average value and the preset average value.
In this embodiment, the preset average value is not limited, and the user can customize the setting. It is understood that when the brightness average value is greater than or equal to the preset average value, the current test result is determined as the first result. For example, when the optomechanical test method is to test the opening and closing of the optomechanical door, the first result is that the door is successfully opened; when the optical machine testing method is an on-off test of the optical machine, the first result is that the lighting is successful.
Of course, when the brightness average value is smaller than the preset average value, the current test result is determined as the second result, for example, when the opto-mechanical test method is to test the opening and closing of the opto-mechanical door, the first result is that the door fails to open; when the opto-mechanical testing method is an on-off test of the opto-mechanical, the first result is a light-up failure.
Further, when the average brightness value is smaller than the preset average value, two situations may exist, the first is that the test image is an image of a projection image, and a dark image, i.e., a dark field image, is displayed, and the other is a non-projection image, i.e., the optical engine is not bright or the door of the optical engine is not opened, so that the accuracy of the obtained result is low only by judging that the optical engine is not bright or the door of the door is not opened by using the average brightness value smaller than the preset average value. In order to solve the technical problem, the embodiment provides a scheme that when the brightness average value is smaller than a preset average value, whether the image is a no-projection image or a dark field image is judged; and determining the current test result according to the judgment result. It can be understood that the optical engine is not bright or the optical engine door is not opened, and the difference between the brightness of the displayed dark image is small, assuming that the brightness value is 200 at the maximum, the brightness of the dark field is 50, and the brightness is 10 when the dark image is not bright, the change value of the brightness jump occurring in the continuous frames is small and should be lower than the difference value 40 between the brightness of the dark field and the brightness when the dark image is not bright, and the dark field and the non-bright condition (no projection image) can be identified through such a change rule. Therefore, the precision of the test result can be improved by the mode.
In another implementation manner, please refer to fig. 3, where fig. 3 is a schematic flow chart of another current test result acquisition provided in the embodiment of the present application, including:
s121b, performing definition calculation on the test image to obtain a definition value.
The present embodiment does not limit the way of calculating the sharpness value, and reference may be made to the related art.
And S122b, determining the current test result according to the definition value.
Specifically, when the definition value is greater than or equal to a preset definition threshold value, the current test result is a first current test result; and when the definition value is smaller than the preset definition threshold value, the current test result is a second current test result. Specifically, when the opto-mechanical testing method is to test the opening and closing of the opto-mechanical door, the first current test result is that the door is successfully opened, and the second current test result is that the door is failed to be opened; when the optical machine testing method is an on-off test of the optical machine, the first result is that the lighting is successful, and the second current testing result is that the lighting is failed.
And S130, displaying the current test result.
And displaying the current test result on the display device, wherein the current test result comprises but is not limited to the test data, the curve corresponding to the test data and the test result.
Based on the technical scheme, the current test result is obtained by using the collected multi-frame test image, and the actual and real current test result can be obtained by using the test image to perform image analysis, so that the wrong current test result caused by data writing in the related technology when analysis is performed according to the log but failure in effect is avoided; in addition, the current test result is obtained by performing image calculation on the test image, and the efficiency of obtaining the current test result is higher than that of obtaining the current test result by utilizing manual judgment in the related technology.
Based on the above embodiments, this embodiment provides a specific optomechanical testing method, mainly tests the switch of the optomechanical door, including:
setting a switch test condition of an optical machine cabin door; acquiring a multi-frame test image of a projection picture acquired by a camera; performing image calculation on a plurality of frames of test images to obtain a current test result; and displaying a current test result, wherein the current test result comprises successful cabin door opening and failed cabin door opening.
The switch test conditions of the optical engine compartment door comprise the test times, the test time and the opening and closing time of the optical engine compartment in each test.
Therefore, the current test result is automatically obtained by carrying out image calculation on the multi-frame test image of the projection image acquired by the camera, the low accuracy that the opening is successfully determined only by inputting the data of the equipment for controlling the opening of the optical engine cabin door according to log analysis in the related technology is avoided, the conditions that the data is not effective and the optical engine cabin door is not opened are ignored, the test result is automatically obtained in the embodiment, manual analysis is not needed, and the test efficiency for testing the opening and closing of the optical engine cabin door is greatly improved.
Based on the foregoing embodiments, this embodiment provides a specific optical machine testing method, and the main on/off test of an optical machine includes:
setting the on-off test condition of the optical machine; acquiring a multi-frame test image of a projection picture acquired by a camera; performing image calculation on a plurality of frames of test images to obtain a current test result; and displaying the current test result, wherein the current test result comprises the successful lighting and the failed lighting.
Specifically, a test device is prepared, and the electronic device projecting the installed test software can be a PC; running the tested projection and PC for 24 to 72 hours; the PC views the generated test report (the camera takes a projection picture). Specifically, in the continuous operation process, an optical machine switch test condition is set in the PC so that the PC can control the optical machine switch, wherein the on-off test condition includes, but is not limited to, the number of tests, the time of the tests, and the time of turning on and off the optical machine during each test, the camera collects a plurality of frames of test images of a projection picture, then the PC performs image calculation on the plurality of frames of test images to obtain a current test result, and displays the test result, and after a period of test is completed, a test report can be viewed at the PC, and the test report includes all the test results and the test images.
Therefore, the embodiment reduces the manual participation in the test and improves the working efficiency; through program analysis test image, more accurate, the people only need set up test platform and test environment, starts the testing tool, and the program can automated inspection, if make mistakes can take a picture the record, can output the test report after accomplishing.
Further, in the on/off test of the optical machine, the current test result is that the lighting is successful, and correspondingly, the image calculation is performed on the multi-frame test image, and after the current test result is obtained, the method further includes: calculating the definition change rate of a third target test image and a fourth target test image in the multi-frame test images; judging whether the definition change rate is smaller than a preset change rate threshold value or not; if the change rate is smaller than the preset change rate threshold value, determining that the projection picture is abnormal; and if the change rate is larger than or equal to the preset change rate threshold value, determining that the projection picture is normal.
Wherein the sharpness change rate is equal to the absolute value of the sharpness difference/interval time. For example, when the sharpness value of the first target test image H is H, the image capturing time is t3, the sharpness value of the second target test image Y is Y, and the image capturing time is t4, the sharpness change rate is the absolute value of the sharpness difference/interval time, i.e., | (H-Y)/(t4-t3) |.
Specifically, when the definition change rate is greater than or equal to the preset change rate threshold, it is determined that the projection picture is normal, and when the definition change rate is less than the preset change rate threshold, it is determined that the projection picture is abnormal, which may be in a wire drawing or screen-blooming state. Therefore, whether the projection picture is normal or abnormal can be determined through the definition change rate, and the universality of the optical machine test is improved.
Further, after displaying the current test result, the method further includes: judging whether the current test frequency meets a preset test frequency in the startup and shutdown condition test; if yes, storing all test results in a database; if the current test frequency does not meet the preset test frequency, executing the step of acquiring the multi-frame test image of the projection picture acquired by the camera until the current test frequency meets the preset test frequency, and storing all test results into a database; and outputting all test results.
It can be understood that 1 is added to the current number of tests after each test is completed, so as to ensure that the completed tests of the current test period are accurately recorded. When the test is finished, all test results are stored in the database so as to be convenient for the user to consult at any time. Of course, for the optical machine test, the test result has only two kinds of results, after all the test results are output, the times of the two kinds of test results in the test of the period are counted, and the final test result of the period is determined according to the times.
For example, when the optomechanical test method is to test the opening and closing of the optomechanical door, the door opening success frequency is g, the ratio is α, when α is greater than or equal to a first preset ratio, the door testing success is determined, when the optomechanical test method is to test the opening and closing of the optomechanical door, the lighting success frequency is f, the ratio is β, and when β is greater than or equal to a second preset ratio, the opening and closing of the optomechanical door is determined to be successful.
