Abstract
Description
Technical Field
[0001] This disclosure relates to the field of electronic product technology, and in particular to a testing device and testing system. Background Technology
[0002] Laptops' Time of Flight (TOF) sensors come with an adaptive dimming function. In adaptive mode, when a user turns their head 55° to 65° in front of the laptop, the screen will automatically dim to save power.
[0003] This function needs to be tested in two scenarios. In the first scenario, with the laptop in adaptive mode, the tester simultaneously turns their head and shoulders left and right at distances of 45cm, 55cm, and 65cm from the computer, with the rotation angle between 55° and 65°, holding each position for 10 seconds. When the TOF (Time-of-Flight) sensor fails to recognize the target image, the computer screen automatically dims. A total of 480 tests are required. In the second scenario, with the laptop in adaptive mode, the tester tilts their head up and down at distances of 45cm, 55cm, and 65cm from the computer, holding each position for 10 seconds. Again, when the TOF sensor fails to recognize the target image, the computer screen automatically dims. A total of 480 tests are required. Currently, testing this function is entirely manual, requiring the person and device to perform different actions at different distances. For a single laptop, this requires up to 960 tests, which is inefficient, time-consuming, labor-intensive, and lacks accuracy. Utility Model Content
[0004] This disclosure provides a testing apparatus and a testing system to at least solve the above-mentioned technical problems existing in the prior art.
[0005] According to a first aspect of this disclosure, a testing apparatus is provided, comprising:
[0006] Track structure,
[0007] The rotating structure includes a base slidably connected to the track structure and a rotating component capable of rotating relative to the base. A support rod is fixedly connected to the center of the rotating component, and a rotating shaft assembly is rotatably connected to the top of the support rod.
[0008] A human body model, fitted around the outer periphery of the support rod, and capable of rotating relative to the base around a first rotation center with the rotating assembly; and
[0009] A human head model is fixedly connected to the rotating shaft assembly and can rotate relative to the support rod around the second rotation center with the rotating shaft assembly;
[0010] The rotating shaft assembly is equipped with an image acquisition and recognition unit to identify the image in front of the human body model and determine the test result. The first rotation center and the second rotation center satisfy the vertical condition.
[0011] In one embodiment, the rotating assembly includes a rotating disk, which is rotatably connected to the base and coaxially arranged with the base, and the support rod is fixed to the rotating disk.
[0012] In one embodiment, the track structure is arranged along a first direction, the support rod is arranged along a second direction, and when the human body model faces the first direction, the rotating component is in an initial position relative to the base, and the rotation angle of the rotating disk is 0°; wherein, the first direction and the second direction satisfy the perpendicular condition.
[0013] In one embodiment, the rotating component also has a rotatable position relative to the base. When the rotating component is in the rotatable position, the rotating disk rotates clockwise or counterclockwise around the first rotation center by a first angle to simulate the human body turning around and turning its head.
[0014] In one possible implementation, the first angle is 55° to 65°.
[0015] In one embodiment, the rotating component further includes a positioning pointer, which is fixed on the rotating disk and points in the same direction as the human body model; the edge of the base is provided with a positioning slot, which can be engaged with the positioning pointer for positioning.
[0016] In one embodiment, the rotating shaft assembly includes a support portion disposed at the top of the support rod, a rotating portion rotatably connected to the support portion, and a connecting portion disposed on the rotating portion. The image acquisition and recognition unit is disposed on the support portion. The human head model is fixedly connected to the connecting portion and can rotate clockwise or counterclockwise around the second rotation center with the rotating portion to simulate the nodding action of a human body.

[0018] In one embodiment, a control component is also included, which is connected to the track structure and the rotating structure.
[0019] According to a second aspect of this disclosure, a testing system is provided, including a testing device and a testing apparatus as described in any of the above embodiments, wherein the device under test is located in front of the track structure and facing the human body model.
[0020] In this disclosure, the testing device utilizes a human body model and a head model, along with a track structure and a rotating structure, to effectively and accurately change the testing distance, turn the head, and nod the head to meet testing requirements. Furthermore, compared to a human subjectively and arbitrarily turning their head, the synchronous rotation of the human body model and head model by the rotating components provides higher accuracy, further ensuring testing accuracy. In addition, the testing device performs automated testing; the image acquisition and recognition unit accurately captures the image from the testing machine and automatically judges the test results, greatly improving testing efficiency and freeing up manpower.

Detailed Implementation
[0030] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0031] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0032] Reference Figure 1 and Figure 2 As shown, this disclosure discloses a testing device in an exemplary embodiment, including a track structure 1, a rotating structure 2, a human body model 3, and a human head model 4. The rotating structure 2 includes a base 21 slidably connected to the track structure 1 and a rotating component 22 capable of rotating relative to the base 21. A support rod 23 is fixedly connected to the center of the rotating component 22, and a rotating shaft assembly 24 is rotatably connected to the top of the support rod 23. The human body model 3 is fitted around the outer periphery of the support rod 23 and can rotate relative to the base 21 around a first rotation center with the rotating component 22. The human head model 4 is fixedly connected to the rotating shaft assembly 24 and can rotate relative to the support rod 23 around a second rotation center with the rotating shaft assembly 24. The rotating shaft assembly 24 is provided with an image acquisition and recognition unit to recognize the image in front of the human body model 3 and determine the test result. The first and second rotation centers satisfy a perpendicular condition.
[0033] In one embodiment, the testing device further includes a control component 5, which is connected to the track structure 1 and the rotating structure 2.
[0034] In this embodiment, it should first be noted that the directions of front, back, left, right, up, and down in this disclosure are based on the direction when the testing device is in normal use. For example, when the rotating structure 2 moves forward along the track structure 1, it causes the human body model 3 and the head model 4 to move closer to the laptop computer under test; when the rotating structure 2 moves backward along the track structure 1, it causes the human body model 3 and the head model 4 to move away from the laptop computer under test. When the rotating component 22 rotates left and right, it causes the human body model 3 and the head model 4 to simulate turning their heads left and right. When the rotating shaft component 24 rotates upward, it causes the head model 4 to raise its head; when the rotating shaft component 24 rotates downward, it causes the head model 4 to lower its head. The control component 5 is connected to the track structure 1 and the rotating structure 2. By pre-programming, it can control the rotating structure 2 to move along the track structure 1 to different set positions, control the rotating component 22 to rotate relative to the base 21 at different set angles, and control the rotating shaft component 24 to rotate up and down. The test apparatus disclosed herein is primarily used to test the adaptive dimming function built into the TOF sensor of a laptop computer. This adaptive dimming function determines whether the user is turning their head based on the difference in reflectivity between the user's front and side faces. When the user is looking at the screen, the screen remains constantly lit; when the user moves away from the screen, the screen automatically dims, thus saving power and reducing interference with others. For example, when the user is talking to someone, the screen automatically dims to protect the user's privacy. A TOF sensor is a sensor that uses the emission and reflection of light waves to measure distance. It determines the distance to an object by calculating the time difference between the emission of light waves to the target object and their reflection back. Specifically, TOF distinguishes between a person and an object based on their appearance and shape, and determines whether the user is turning their head based on the difference in reflectivity between the user's front and side faces, with reflectivity determined by human skin. Therefore, the shapes of the human body model 3 and the head model 4 need to be designed to be similar to and nearly identical to those of real people. The materials used for the human body model 3 and the head model 4 must be commercially available artificial skin with a 99% similarity to real skin. Since the test requires that at least 85 out of every 100 tests meet the requirements, the test is considered passed, and the 1% error due to the difference between real and artificial skin can be ignored. The human body model 3 and the head model 4 are respectively mounted on the support rod 23 and the rotating shaft assembly 24, facilitating individual disassembly and replacement of the models. In summary, the testing device disclosed herein uses the human body model 3 and the head model 4, combined with the track structure 1 and the rotating structure 2, to effectively and accurately complete changes in test distance, head turning, and nodding movements to meet test requirements. Compared to the subjective, arbitrary head turning angle of a real person, the synchronous rotation of the human body model 3 and the head model 4 by the rotating assembly 22 is more accurate, further ensuring the accuracy of the test. Furthermore, the testing device performs automated testing; the image acquisition and recognition unit can accurately capture the image of the testing machine and automatically judge the test results, greatly improving testing efficiency and freeing up manpower.
[0035] In one embodiment, the rotating assembly 22 includes a rotating disk 221, which is rotatably connected to the base 21 and is coaxially arranged with the base 21. A support rod 23 is fixed on the rotating disk 221.
[0036] Specifically, in one embodiment, the track structure 1 is arranged along a first direction, and the support rod 23 is arranged along a second direction. When the human body model 3 faces the first direction, the rotating component 22 is in its initial position relative to the base 21, and the rotation angle of the rotating disk 221 is 0°. The first direction and the second direction satisfy the perpendicularity condition.
[0037] In this embodiment, the first direction is the direction in which the rotating structure 2 can move closer to or further away from the laptop under test, which is the X direction in the three-dimensional Cartesian coordinate system. The second direction is the direction in which the vertical direction is located, which is the Z direction in the three-dimensional Cartesian coordinate system. When the human body model 3 is facing the laptop under test, the rotation angle of the rotating disk 221 is 0°.
[0038] In one embodiment, the rotating component 22 also has a rotatable position relative to the base 21. When the rotating component 22 is in the rotatable position, the rotating disk 221 rotates clockwise or counterclockwise around the first rotation center by a first angle to simulate the turning and rotating movements of a human body.
[0039] Specifically, in one embodiment, the first angle is 55° to 65°.
[0040] Preferably, the first angle is 60°.
[0041] In this embodiment, the rotating disk 221 rotates clockwise or counterclockwise around the first rotation center, that is, the rotating disk 221 rotates to the right or left, so that the human body model 3 and the human head model 4 rotate to the right or left by a first angle. Since the first angle of 55° and 65° are the boundary angles between the test pass and the test failure, which are prone to errors and lead to inaccurate test results, the first angle is preferably 60° during the test.
[0042] In one embodiment, the rotating component 22 further includes a positioning pointer 222, which is fixed on the rotating disk 221. The direction pointed to by the positioning pointer 222 is the same as the orientation of the human body model 3. The edge of the base 21 is provided with a positioning slot 211, which can be positioned with the positioning pointer 222.
[0043] In this embodiment, by setting a positioning pointer 222, which works with the positioning slot 211 to lock and limit the position, it not only positions the rotation angle but also indicates the rotation angle, making the testing process more intuitive and allowing personnel to observe in a timely manner whether the testing conditions meet the requirements.
[0044] In one embodiment, the rotating shaft assembly 24 includes a support portion 241 disposed at the top of the support rod 23, a rotating portion 242 rotatably connected to the support portion 241, and a connecting portion 243 disposed on the rotating portion 242. The image acquisition and recognition unit is disposed on the support portion 241. The human head model 4 is fixedly connected to the connecting portion 243 and can rotate clockwise or counterclockwise around the second rotation center with the rotating portion 242 to simulate the nodding action of a human body.
[0045] In one embodiment, the rotating structure 2 has at least a first position, a second position and a third position on the track structure 1, and a scale display part is provided on the track structure 1 along the length direction of the track structure 1.
[0046] In this embodiment, it is sufficient to ensure that the distance between the laptop under test and the human body model 3 is at least 45cm, 55cm, and 65cm. For example, when the rotating structure 2 is in the first position on the track structure 1, the position of the rotating structure 2 on the track structure 1 corresponding to the scale display is 0cm, and the laptop under test is 45cm in front of this position; when the rotating structure 2 is in the second position on the track structure 1, the position of the rotating structure 2 on the track structure 1 corresponding to the scale display is 10cm, and the laptop under test is 55cm in front of this position; when the rotating mechanism is in the third position on the track structure 1, the position of the rotating structure 2 on the track structure 1 corresponding to the scale display is 20cm, and the laptop under test is 65cm in front of this position.
[0047] Reference Figure 3 As shown, this disclosure also provides a testing system, including a device under test 6 and a testing apparatus as described in any of the above embodiments, wherein the device under test 6 is located in front of the track structure 1 and is positioned toward the human body model 3.
[0048] In this embodiment, the device under test 6 is usually a laptop computer. At the beginning of the test, the device under test 6 is positioned in front of the track structure 1, facing the human body model 3. The human head model 4 is also in a level position and does not rotate up or down. The distance between the human body model 3 and the device under test 6 is 45cm.
[0049] Reference Figure 4As shown, in the first test scenario, the test device has two preset programs: program one is to rotate to the left and program two is to rotate to the right. After the test begins, the image acquisition and recognition unit acquires photo 1 of the device under test 6, then starts the test device and selects program 1 or program 2. Correspondingly, the rotating disk 221 rotates 60° to the left or right and holds at the 60° left or right position for 10 seconds. Then, the image acquisition and recognition unit acquires photo 2 of the device under test 6. The brightness of photo 1 and photo 2 is compared to determine whether the brightness of photo 2 is lower than that of photo 1. If so, the test is recorded as passed and the test count is incremented by one. If not, the test is recorded as failed and the test count is incremented by one. After the test count is incremented by one, it is determined whether the set number of cycles of 40 has been reached. If not, the test cycle is repeated and program 1 or program 2 is executed again. If so, the rotating structure 2 is controlled to move to a position where the distance between the human body model 3 and the device under test 6 is 55cm or 65cm. The test cycle is repeated and the test device is started again and program 1 or program 2 is selected. After 240 tests, the test structure is statistically analyzed, and the test is completed.
[0050] Reference Figure 5 As shown, in the second test scenario, the test device has two preset programs: Program 1 is "looking up," and Program 2 is "looking down." After the test begins, the image acquisition and recognition unit acquires photo 1 of the device under test 6, then starts the test device and selects Program 1 or Program 2. Correspondingly, the rotating shaft assembly 24 rotates up or down and holds the up or down position for 10 seconds. Then, the image acquisition and recognition unit acquires photo 2 of the device under test 6. The brightness of photo 1 and photo 2 is compared to determine whether the brightness of photo 2 is lower than that of photo 1. If so, the test is recorded as passed and the test count is incremented by one. If not, the test is recorded as failed and the test count is incremented by one. After the test count is incremented by one, it is determined whether the set number of cycles of 40 has been reached. If not, the test is repeated using Program 1 or Program 2. If so, the rotating structure 2 is controlled to move to a position where the distance between the human body model 3 and the device under test 6 is 55cm or 65cm. The test is repeated, and the test device is started again and Program 1 or Program 2 is selected. After 240 tests, the test structure is statistically analyzed, and the test is completed.
[0051] Furthermore, a third test scenario is provided. The test device has four preset programs: program one is leftward rotation, program two is rightward rotation, program three is head tilting, and program four is head tilting. After the test begins, the image acquisition and recognition unit acquires photo one of the device under test 6, then starts the test device and selects program one or program two. Correspondingly, the rotating disk 221 rotates 60° to the left or right. Based on the previous step, program three or program four is selected. Correspondingly, based on the rotating disk 221 at the 60° left or right position, the rotating shaft assembly 24 rotates up or down and holds the up or down position for 10 seconds. Then, the image acquisition and recognition unit acquires photo two of the device under test 6. The brightness of photo one and photo two is compared to determine whether photo two is... If the brightness is lower than that of Photo 1, the test is recorded as passed and the test count is incremented by one; otherwise, the test is recorded as failed and the test count is incremented by one. After incrementing the test count, it is determined whether the set number of cycles (40) has been reached. If not, the test cycle is repeated using Program 1 or Program 2. If so, the rotating structure 2 is moved to a position where the distance between the human model 3 and the device under test 6 is 55cm or 65cm, and the test cycle is repeated to restart the test device and select Program 1 or Program 2. After 480 tests, the test structure is statistically analyzed, and the test is completed.
[0052] Understandably, the testing process of the testing system can be adaptively configured according to actual needs. The testing system disclosed herein uses testing equipment, employing a human body model 3 and a head model 4, along with a track structure 1 and a rotating structure 2. This allows for effective and precise control of changes in testing distance, head turning, and nodding movements to meet testing requirements. Furthermore, compared to the subjective, arbitrary head turning of a human, the synchronous rotation of the human body model 3 and head model 4 by the rotating component 22 provides higher accuracy, further ensuring testing accuracy. In addition, the testing device performs automated testing; the image acquisition and recognition unit accurately captures the image from the testing machine and automatically judges the test results, greatly improving testing efficiency and freeing up manpower.
