[0050] <System Embodiment>

[0051] The present disclosure provides a testing system. Figure 1 It is a hardware schematic diagram of a test system provided according to an embodiment of the present disclosure.

[0052] Reference Figure 1 The test system 1 includes a device under test 11, a host computer 12, a camera 13 and a power supply 14, a serial port board 15, a first network card 16 and a second network card 17.

[0053] It should be noted that in order to prevent the test process from being affected by the external environment, the device under test 11, camera 13, power supply 14, serial port board 15, first network card 16 and second network card 17 in the test system 1 can be placed in a dark box.

[0054] The power supply 14 is connected to the host computer 12 through the second network card 17, and the power supply 14 is also connected to the device under test 11. The host computer 12 controls the power supply 14 to supply power to the device under test 11 through the second network card 17. Generally, the power supply 14 can be a DC power supply, and this embodiment does not limit the model of the DC power supply.

[0055] The host computer 12 is connected to the device under test 11 via the serial port board 15 , and the host computer 12 is used to send a control instruction for controlling the device under test 11 to move to the device under test 11 via the serial port board 15 .

[0056] Usually, the serial port board 15 can be a USB to UART serial port chip, through which a seamless conversion between a USB interface and a UART serial port can be realized. The operator can convert a USB interface to a UART serial port through a simple plug-in operation, thereby realizing serial port communication between devices.

[0057] The camera 13 is connected to the host computer 12 via the first network card 16 , and the host computer 12 is used to control the camera 13 to record the movement process of the device under test 11 to obtain a first recorded video, and analyze the first recorded video to obtain a target test result of the device under test 11 .

[0058] <Method Example>

[0059] Figure 2 A test method for a device under test according to an embodiment of the present disclosure is shown. The test method for the device under test can be implemented by a host computer, which can be Figure 1 The host computer 12 shown in the figure, wherein the host computer is connected to the device under test, the power supply and the camera respectively, and the power supply is connected to the device under test. Figure 2 As shown, the testing method of the device under test in this embodiment may include the following steps S2100 to S2300:

[0060] Step S2100: Controlling the movement of the device under test while the device under test is powered by the power supply.

[0061] The power supply may be a DC power supply, and this embodiment does not limit the type of the DC power supply.

[0062] In this embodiment, the host computer may send a power supply instruction to the power supply, so that the power supply supplies power to the device under test based on the power supply parameters carried in the power supply instruction.

[0063] The power supply parameter may be a voltage, which is usually a voltage when the device under test is in a normal working state.

[0064] Specifically, refer to Figure 1 and Figure 3 , the host computer is connected to the power supply through the second network card, and the power supply is also connected to the device under test. The host computer can send a power supply instruction to the power supply through the second network card, and the power supply instruction carries a voltage at which the device under test can work normally. After the power supply receives the power supply instruction sent by the host computer, it can supply power to the device under test based on the voltage to ensure that a normal working environment is provided for the device under test.

[0065] In an optional embodiment, in this step S2100, when the device under test is powered by the power supply, controlling the movement of the device under test may further include: when the device under test is powered by the power supply, sending a control instruction for controlling the movement of the device under test to the device under test, so that the device under test moves according to the control instruction.

[0066] The control instruction may be a Uart instruction.

[0067] Specifically, refer to Figure 1 and Figure 3 , the host computer is connected to the device under test through the serial port board. When the device under test is powered by the power supply, the host computer can send a control instruction for controlling the movement of the device under test to the device under test. After the device under test receives the control instruction sent by the host computer, it can start to move. It should be noted that the so-called movement includes, for example but not limited to, lighting effects and sports movements.

[0068] In another optional embodiment, when the device under test receives the control instruction sent by the host computer, it can respond to the control instruction and return a confirmation instruction to the host computer to confirm whether it moves normally. The confirmation instruction is a Uart instruction.

[0069] After executing the above step S2100 and controlling the movement of the device under test in the case where the device under test is powered by the power supply, the following steps are performed:

[0070] Step S2200: When the device under test is in motion, control the camera to record the motion process of the device under test to obtain a first recorded video.

[0071] The first recorded video includes a second recorded video of each round of movement of the device under test in the multiple rounds of movement during the movement process.

[0072] Generally, a round of motion in a motion process refers to a complete motion. For example, taking the motion structure in the device under test in motion as an example, the motion structure moving from the bottom to the top and then returning from the top to the bottom can be called a round of motion. In a motion process, generally multiple rounds of motion are included.

[0073] Specifically, refer to Figure 1 and Figure 3 , the host computer is connected to the camera through the first network card. When the device under test is in motion, the host computer can send a recording instruction to the camera through the first network card. After the camera receives the recording instruction, it can record each round of multiple rounds of motion of the device under test during the motion process, obtain the second recorded video corresponding to the multiple rounds of motion, and return it to the host computer through the first network card. The host computer will analyze the recorded video through the open source computer vision library (OpenCV) to obtain the test results of the device under test. It can be understood that the recorded video includes, for example but not limited to, the motion trajectory and light changes to be tested.

[0074] When the device under test is in motion during the execution of step S2200, the camera is controlled to record the motion process of the device under test. After obtaining the first recorded video, the following steps are performed:

[0075] Step S2300: Obtain a target test result of the device under test according to the first recorded video.

[0076] In an optional embodiment, the step S2300 of obtaining the target test result of the device under test according to the first recorded video may further include the following steps S2310 to S2330:

[0077] Step S2310: for any wheel movement of the device under test during the movement process, compare the second recorded video of the device under test in the any wheel movement with the standard video to obtain a first test result of the device under test in the any wheel movement.

[0078] Among them, the standard video is a recorded video that has passed manual inspection. Usually, when the device under test is in the first round of movement, on the one hand, the camera can record the device under test to obtain a second recorded video; on the other hand, the tester's human eyes will also observe the movement of the device under test. If the second recorded video of the first round of movement passes the manual verification, the second recorded video of the first round of movement can be used as the standard video. It can be understood that if the second recorded video obtained by the first round of movement recording fails to pass the manual verification, the second recorded video obtained by the second round of movement recording will continue to be manually verified until the second recorded video obtained by a certain round of movement recording passes the manual verification, and the second recorded video obtained by the round of movement recording is stored in the host computer as the standard video.

[0079] Optionally, this step S2310 compares the second recorded video of the device under test in the arbitrary wheel movement with the standard video for any wheel movement of the device under test during the movement process, and obtaining the first test result of the device under test in the arbitrary wheel movement may further include the following steps S2311 to S2313:

[0080] Step S2311: for any round of motion of the device under test during the motion process, grayscale processing is performed on each frame of the second recorded video of the device under test and each frame of the standard video in the any round of motion.

[0081] Step S2312, obtaining the similarity between each frame image of the second recorded video after grayscale processing and the corresponding frame image of the standard video.

[0082] Step S2313, obtaining a first test result of the device under test in the arbitrary wheel motion according to the similarity between each frame image of the second recorded video after grayscale processing and the corresponding frame image of the standard video.

[0083] Next, the above steps S2311 to S2313 are explained. The upper computer reads each frame of the stored standard video through the cv2.imread() function in OpenCV, and converts each frame of the image from the BGR color space to the grayscale space through the cv2.cvtColor() function in OpenCV to facilitate image grayscale analysis, and saves each frame of the processed grayscale image through the cv2.imwrite() function in OpenCV.

[0084] In addition, after receiving the second recorded video of the device under test in any wheel motion sent by the camera, the host computer will also read each frame of the second recorded video through the cv2.imread() function, and convert each frame of the image from the BGR color space to the grayscale space through the cv2.cvtColor() function to facilitate image grayscale analysis, and save each frame of the processed grayscale image through the cv2.imwrite() function.

[0085] Finally, the host machine will use the cv2.matchTemplate() function in OpenCV to compare the similarity of each frame of the standard video and each frame of the second recorded video to achieve comparative analysis of the recorded images. Among them, this function evaluates the similarity of two frames of images by calculating the structural similarity index (SSIM). Generally, the similarity ranges from -1 to 1, and the closer the value is to 1, the more similar the two frames of images are. During the test, the host machine will use the above algorithm to compare and analyze the second recorded video of each round of movement of the device under test with the standard video, and obtain the preliminary test results of each round of movement as the first test results of each round of movement.

[0086] Step S2320: obtaining a second test result of the device under test in the arbitrary wheel motion according to the first test result of the device under test in the arbitrary wheel motion.

[0087] Optionally, the step S2320 of obtaining the second test result of the device under test in the arbitrary wheel motion according to the first test result of the device under test in the arbitrary wheel motion may further include the following steps S2321 to S2322:

[0088] Step S2321: for any wheel movement of the device under test during the movement process, obtain the movement time of the device under test in the any wheel movement.

[0089] For example, taking the moving structure in the device under test being in motion as an example, since the moving structure moves from the bottom to the top and then returns from the top to the bottom, which can be called a round of motion, the time for the moving structure to move from the bottom to the top and then returns from the top to the bottom is the motion time of the device under test in the round of motion. For example, the motion time can be 3s, 6s, etc., depending on the actual test, and this embodiment does not limit this.

[0090] Step S2322, obtaining a second test result of the device under test during the arbitrary wheel movement according to the first test result of the device under test during the arbitrary wheel movement, the movement time, and a confirmation instruction returned by the device under test in response to the power supply instruction as to whether the arbitrary wheel moves normally.

[0091] Specifically, after the upper computer obtains the first test result of each round of movement of the device under test during the movement process, for any round of movement, the upper computer can combine the first test result of the device under test in that round of movement, the movement time, and the confirmation instruction returned by the device under test in response to the power supply instruction as to whether the round of movement is normal, to obtain the second test result of the device under test in that round of movement.

[0092] According to the above steps S2311 to S2322, the host computer combines the preliminary test results of each round of movement, the movement time of the device under test in each round of movement, and the confirmation instruction of whether each round of movement of the device under test is normal in response to the power supply instruction, and obtains the confirmation instruction of the device under test in each round of movement. final Test results, test results are more accurate.

[0093] Step S2330: Obtain a target test result of the device under test according to the second test result of each round of movement of the device under test in the multiple rounds of movement.

[0094] Specifically, the host computer may combine the second test result of each round of movement of the device under test in multiple rounds of movement into the target test result of the device under test.

[0095] Specifically, after obtaining the target test result of the device under test, the host computer will save the target test result to a local file. If the test result corresponding to a certain round of movement in the target test result is passed, the test result of the certain round of movement can be marked as Pass; if the test result corresponding to a certain round of movement in the target test result is failed, the test result of the certain round of movement can be recorded as Fail.

[0096] It should be noted that the host computer will also perform statistical analysis on the target test results. For example, when a Fail item appears in the target test results, the host computer will read the current voltage and current, compare and analyze them with the voltage and current of the normal operation of the device under test, and record them in the test log. This will determine whether the test failure is caused by unstable power supply voltage / current, thereby saving R&D analysis time.

[0097] According to the embodiment of the present disclosure, the host computer is connected to the device under test, the power supply and the camera respectively, and the power supply is also connected to the device under test. Specifically, the host computer can control the power supply to supply power to the device under test, and when the power supply is used to supply power to the device under test, the host computer can control the movement of the device under test, and when the control device is in motion, control the camera to record the movement process of the device under test to obtain a first recorded video, and then obtain the target test result of the device under test according to the first recorded video. Through the embodiment of the present disclosure, based on the hardware foundation of the host computer, the camera and the power supply, dynamic automatic testing of the device under test is realized, saving human resources and time.
