Description
Technical Field
[0001] This utility model relates to the field of AR glasses technology, and in particular to an AR glasses auxiliary testing device. Background Technology
[0002] With the continuous development of information technology, augmented reality (AR) technology has received much attention in recent years. Augmented reality is a technology that cleverly integrates virtual information with the real world. It simulates and applies computer-generated virtual information to the real world, with the two types of information complementing each other to "enhance" the real world.
[0003] As a mainstream display technology for AR glasses, the performance of optical waveguides greatly affects the user experience. Therefore, accurately measuring the display performance of optical waveguides in AR glasses is crucial for improving the overall manufacturing process of AR glasses.
[0004] In related technologies, AR glasses are mainly supported by head molds, and the performance of the glasses is tested using equipment such as luminance meters. However, head molds are expensive to manufacture, have complex testing structures, are not compatible with different glasses, and cannot accurately locate the eye point for measurement. Utility Model Content

This results in accurate test results, good repeatability, improved testing efficiency, and reduced testing costs. During the test, the temples of the AR glasses can be placed on the side support, while the main body of the AR glasses is placed on the main support. By rotating the side support and adjusting the temples placed on it to be outside the test path of the test camera, interference from the temples to the test process can be effectively avoided.

[0011] In some examples, two alignment portions are spaced apart on the first surface, and the angle between the mating surfaces of the two alignment portions and the first surface is the same; or, the mating surfaces of the two alignment portions are parallel to the first surface.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0034] Where there is no conflict, the following embodiments and features can be combined with each other.
[0035] AR glasses are head-mounted devices, and when testing their waveguide display performance, they need to be fixed in place, and a suitable testing or viewing angle needs to be determined. Specifically, a CCD can be used to test the optical waveguide, achieving non-destructive, high-precision, and rapid measurement of the waveguide's performance. The CCD can capture the distribution of scattered light intensity on the optical waveguide transmission line to determine the waveguide's transmission loss.
[0036] The head model used in the testing process of related technologies can only provide some support for AR glasses. It cannot accurately adjust the alignment angle between each pair of glasses and the test camera during testing, nor can it accurately locate the eye point for measurement.
[0037] In view of this, the present invention proposes an AR glasses auxiliary testing device 100.
[0038] like Figures 1 to 5 As shown, the AR glasses auxiliary testing device 100 proposed in this utility model is used to support the AR glasses to be tested (not shown) and align them with the test camera (not shown). The AR glasses auxiliary testing device 100 includes: a support fixture 10 and an alignment fixture 20.
[0039] like Figure 1As shown, the support fixture 10 includes a main support 11 and a side support 12. The main support 11 supports the main body of the AR glasses, allowing the AR glasses to face the test camera. The side support 12 is rotatable relative to the main support 11 and is used to hold the temples of the AR glasses, so that adjusting the side support 12 will adjust the angle of the temples.
[0040] Furthermore, combined Figure 1 and Figure 2 As shown, the alignment fixture 20 is mounted on the main support 11. That is, the main support 11 of the present invention can also have the alignment fixture 20 mounted on it when determining the eye point position of the AR glasses, and the alignment fixture 20 removed before testing the AR glasses, and the AR glasses to be tested placed in it.
[0041] Furthermore, the main body 21 of the alignment fixture 20 is provided with an outwardly protruding alignment part 22, which is used to align with the test camera.
[0042] As can be seen from the above technical solution, the AR glasses auxiliary testing device 100 proposed in this utility model, by installing different alignment fixtures 20 on the main support body 11, can accurately locate the test eye point position of different AR glasses after the test camera and alignment part 22 are aligned. It can also adjust the test eye point position of the same AR glasses at different angles, thereby realizing the test camera's testing of the waveguide display performance of the same AR glasses at different angles, or realizing the test camera's accurate positioning of the test eye point position of different AR glasses. After finding the test position, the AR glasses to be tested can be placed on the main support body 11, and the test camera will then perform waveguide testing on the AR glasses at the previously positioned position. In the above testing process, it is only necessary to install and remove different alignment fixtures 20 and adjust the test camera and alignment part 22 to achieve alignment. The operation is simple, the structure design of the alignment fixture 20 is simple, resulting in accurate test results, good repeatability, improved testing efficiency, and reduced testing costs.
[0043] During the test, the temples of the AR glasses can be placed on the side support 12, while the main body of the AR glasses is placed on the main support 11. By rotating the side support 12 and adjusting the temples placed on it to be outside the test path of the test camera, the interference of the temples on the test process can be effectively avoided. This ensures that there are no other obstacles interfering with the test camera's testing of the AR glasses' optical waveguide, further improving the accuracy of the test results.
[0044] Furthermore, since the rotation angle of the adjustable side support 12 of this invention is adjustable, it can be compatible with AR glasses that support different temple angles.
[0045] It is understandable that, compared to the use of head molds to support AR glasses in the prior art, the AR glasses auxiliary testing device 100 of this embodiment has a simple structure, and the test eye point of different AR glasses can be accurately located by replacing the alignment fixture 20 with the alignment part 22 which has a different structure.
[0046] In this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the main support body 11 is also provided with mounting holes 113. Fasteners can pass through the mounting holes 113 to fix the carrier fixture 10 on the test table, so that the carrier fixture 10 provides reliable support for the alignment fixture 20 or the AR glasses under test, and makes the position of the AR glasses under test relative to the test camera within a measurable range, which facilitates the measurement of the optical waveguide.
[0047] In this invention, the adjustable angle of the side support 12 relative to the main support 11 can be achieved by setting a hinge structure between the two; alternatively, a pivot axis can be used between the side support 12 and the main support 11 to achieve rotation, and a telescopic electric cylinder or a small linear motor can be used to fix the position of the side support 12 relative to the main support 11 after it is opened to a certain angle; alternatively, a bolt can be used to connect the two, with the upper part of the bolt having a thread and the lower part having a smooth surface. When the bolt is screwed downward into the mounting hole, the side support 12 can be fixed in a specific position relative to the main support 11. When it is necessary to adjust the angle between the two, the bolt is screwed upward out of the mounting hole, leaving the smooth surface of the bolt in the mounting hole, and the side support 12 can be rotated relative to the main support 11 using the bolt as a rotation axis. The above structures are only exemplary, and the adjustable angle of the side support 12 relative to the main support 11 can also be implemented in other possible ways, which are not limited by this invention.
[0048] In addition, the side support 12 can rotate relative to the main support 11 at angles from 0 to 90 degrees, such as 0, 10, 15, 20, 30, 40, 60, 70, 80, and 90 degrees.
[0049] In some embodiments of this utility model, the alignment fixture 20 and the main support 11 are detachably connected.
[0050] For example, bolt holes can be provided on one of the alignment fixture 20 and the main support body 11 and through holes can be provided on the other. Fasteners can be screwed into the bolt holes to achieve the connection between the alignment fixture 20 and the main support body 11.
[0051] For example, one of the alignment fixture 20 and the main support body 11 is provided with a slot, and the other is provided with a buckle. The buckle and the slot cooperate to realize the connection between the alignment fixture 20 and the main support body 11.
[0052] For example, the alignment fixture 20 and the main support 11 are connected by a plug-in connection. Specifically, as shown below... Figure 2 As shown, the main support body 11 is provided with multiple slots 111, such as... Figure 4 As shown, the alignment fixture 20 is provided with multiple insertion posts 2111. When the multiple insertion posts 2111 are inserted one-to-one into the slots 111, the alignment fixture 20 is mounted on the main support body 11. In these examples, the plug-in connection structure is simple and facilitates the assembly and disassembly of the alignment fixture 20.
[0053] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.
[0054] In some specific examples, such as Figure 5 As shown, each end of the main support 11 has a slot 111, and each alignment fixture 20 has a corresponding pin 2111. This allows the alignment fixture 20 and the main support 11 to be stably installed relative to the main support 11 by using only the minimum number of pins 2111 and slots 111. The installation position is uniquely determined. After installation, part of the bottom surface of the alignment fixture 20 can contact part of the surface of the main support 11 to form a stable surface support, ensuring that the alignment fixture 20 will not move during the testing process of the test camera.
[0055] In some examples of this utility model, such as Figure 3 As shown, the support fixture 10 also includes two lugs 114, which are perpendicular to the surface of the main support 11. Each lug 114 is positioned close to a slot 111, which is located between the lugs 114 and the side support 12. When the insertion post 2111 of the alignment fixture 20 is inserted into the slot 111, the bottom of the alignment fixture 20 contacts the main support 11, the rear of the alignment fixture 20 contacts the lugs 114, and the front of the alignment fixture 20 contacts the side support 12. This makes the position of the alignment fixture 20 relative to the support fixture 10 relatively fixed, so that it will not shake when the test camera is aligned, and the test is accurate.
[0056] In some embodiments of this utility model, such as Figure 3As shown, the main body 21 includes a first connecting portion 211 and a second connecting portion 212 that are perpendicularly connected to each other. The first connecting portion 211 is installed in contact with the main support body 11. The first surface 2121 of the second connecting portion 212 has a protruding alignment portion 22, and the side of the alignment portion 22 away from the second connecting portion 212 forms a mating surface 221. In these examples, the perpendicularly connected first connecting portion 211 and second connecting portion 212 allow the main body 21 to have two surfaces with different spatial orientations. On one surface, the first connecting portion 211 is conveniently equipped with the aforementioned insertion post 2111 and can form a stable contact with the main support body 11. On the other surface, the second connecting portion 212 can face the testing direction of the test camera, and the alignment portion 22 is provided thereon for alignment with the test camera.
[0057] In a specific example, the first connecting part 211 can contact and limit the aforementioned support lug 114, main support 11 and side support 12 respectively, thereby fixing the position of the alignment fixture 20 relative to the carrying fixture 10.
[0058] Furthermore, such as Figure 3 As shown, the mating surface 221 is parallel to or at an angle to the first surface 2121. That is, when the mating surface 221 is parallel to the first surface 2121, after the alignment part 22 is aligned with the test camera, the observation angle of the camera under test is kept unchanged, the alignment fixture 20 is removed, and the AR glasses under test are placed on the main support 11. The main body of the AR glasses is mainly on the surface where the first surface 2121 of the original second connecting part 212 is located, and the test camera will test the optical waveguide perpendicular to the main body of the AR glasses. When the mating surface 221 is at an angle to the first surface 2121, after the alignment part 22 is aligned with the test camera, the observation angle of the camera under test is kept unchanged, the alignment fixture 20 is removed, and the AR glasses under test are placed on the main support 11. The main body of the AR glasses is still on the surface where the first surface 2121 of the original second connecting part 212 is located, and the test camera will test the optical waveguide of the AR glasses under test at the observation angle determined by the previous alignment.
[0059] Since light of a specific wavelength enters the waveguide of AR glasses at a specific angle, it will be diffracted by the grating structure of the waveguide to achieve coupling in and out, thus allowing the light to propagate in the waveguide. Therefore, during the testing process, the test camera also needs to be positioned at a certain angle to detect the waveguide of the AR glasses under test in order to measure the transmission loss of the waveguide.
[0060] In some examples, two alignment portions 22 are spaced apart on the first surface 2121, and the angles formed by the mating surfaces 221 of the two alignment portions 22 and the first surface 2121 are the same; or, the mating surfaces 221 of the two alignment portions 22 are both parallel to the first surface 2121. In these examples, the two alignment portions 22 can each simulate the optical waveguide region corresponding to an eyeball. When the two alignment portions 22 are simultaneously aligned with two test cameras, the transmission performance of the optical waveguides in the two regions of the AR glasses under test can be accurately measured, thereby further improving the testing efficiency of the AR glasses under test. In addition, the distance between the centers of the two alignment portions 22 of different alignment fixtures 20 can be set differently, thereby simulating the interpupillary distance of different AR glasses corresponding to different eye distances of different people, improving the accuracy and compatibility of testing the optical waveguide performance of different interpupillary distances. In other words, this utility model can simulate the human eye's observation angle and observation distance by setting two alignment portions 22. Alignment is achieved by adjusting the alignment unit 22 with the test camera. After alignment, the alignment fixture 20 is removed, and the AR glasses are placed in the adjusted position, thus enabling accurate measurement of the performance of the AR glasses' optical waveguide. The alignment process is simple, convenient, efficient, and reusable.
[0061] In a specific example, the alignment part 22 is cylindrical. After the alignment part 22 is aligned with the test camera, the lens outline of the test camera coincides with the outer outline of the alignment part 22. That is, the lens outline of the test camera is circular, and the outer outline of the alignment part 22 is also circular. When the two are completely aligned, it indicates that the optical axis center of the test camera coincides with the detection point of the optical waveguide under test, and the detection angle is appropriate, making the alignment more accurate and easier to distinguish. This improves the accuracy of the alignment and the convenience of operation, and also improves the reliability of the test results.
[0062] In other specific examples, the alignment part 22 is cylindrical. After the alignment part 22 is aligned with the test camera, the lens axis of the test camera coincides with the central axis of the mating surface 221 of the alignment part 22. In these examples, it can also be ensured that the optical axis center of the test camera coincides with the detection point of the optical waveguide under test, and the detection angle is appropriate, making the alignment more accurate and the detection results more reliable.
[0063] In some embodiments of this utility model, such as Figure 1 and Figure 3As shown, the side supports 12 include two components, each rotatably connected to one end of the main support 11. The two side supports 12 can rotate in directions away from or towards each other. When two side supports 12 are provided, the two temples can be adjusted, ensuring that the AR glasses with two temples avoid the test path of the test camera during testing, preventing interference from the temples during the test of the AR glasses' waveguide. The side supports 12 also further fix the two temples, ensuring that the entire AR glasses under test maintain a fixed posture and specific position relative to the support fixture 10, remaining stable during testing. This ensures a stable optical path propagation during the test of the waveguide by the test camera, resulting in accurate and reliable test results.
[0064] In specific examples, such as Figure 1 and Figure 3 As shown, the side support 12 is provided with a first groove 121. The opening of the first groove 121 faces the side where the alignment fixture 20 is installed, and the first groove 121 is used to place the temples. That is, by inserting the temples into the first groove 121, both temples of the AR glasses can change their angle relative to the main body of the AR glasses as the side support 12 rotates. The side of the first groove 121 facing the alignment fixture 20 is also the side facing the test camera, which facilitates the placement of the AR glasses under test and facilitates the test camera to detect the optical waveguide of the AR glasses.
[0065] In some examples of this utility model, such as Figure 3 As shown, the main support 11 is provided with a second groove 112, which is used to clamp part of the AR glasses, making the AR glasses more stable relative to the support fixture 10 and less prone to wobbling during testing, thus improving the accuracy of the test camera in testing the optical waveguide. By clamping part of the AR glasses with the second groove 112 and fixing the two temples of the AR glasses with the two first grooves 121, at least three parts of the AR glasses under test are fixed to the support fixture 10, thereby greatly improving the stability of the AR glasses during testing.
[0066] This utility model can use different support fixtures 10 paired with different alignment fixtures 20. The second groove 112 on different support fixtures 10 can have different widths, thereby adapting to clamp AR glasses of different thicknesses and improving the versatility, practicality and compatibility of the AR glasses auxiliary testing device 100 of this utility model.
[0067] In some examples, the main support 11 includes a fixing part and a clamping part, with the sides of the fixing part and the clamping part facing each other forming a second groove 112. The clamping part can be adjusted relative to the fixing part to change the clamping width of the second groove 112. In these examples, only one support fixture 10 is needed to clamp AR glasses of different thicknesses, making it highly adaptable.
[0068] In a specific example, bolt holes can be provided on the fixing part, and the distance between the fixing part and the clamping part can be adjusted by adjusting the depth of the bolt installed on the clamping part in the bolt holes, that is, adjusting the clamping width of the second groove 112; after the main body of the AR glasses is placed in the second groove 112, the main body of the AR glasses can be clamped by further tightening the bolts.
[0069] In some other specific examples, the main support 11 includes a base, a fixing part, and a clamping part. A spring is provided on the side of the clamping part away from the fixing part, and the other end of the spring is provided on the base. The spring usually drives the clamping part to move towards the fixing part, so that the main body of the AR glasses can be clamped between the clamping part and the fixing part. By applying force to the clamping part to overcome the spring force, the distance between the clamping part and the fixing part can be adjusted, and the main body of the AR glasses can be placed in the second groove 112 to fix the main body of the AR glasses.
[0070] In summary, the AR glasses auxiliary testing device 100 of the present invention can effectively support AR glasses and adjust the temple angles of the AR glasses, accommodating AR glasses with different temple angles. During testing, the test camera and temples do not interfere with each other. By aligning the alignment part 22 with the test camera, the accurate test eye point position can be found, resulting in high accuracy and repeatability of the test results. It is compatible with AR glasses testing with different interpupillary distances and can also meet the requirements of different waveguide testing angles. The entire AR glasses auxiliary testing device 100 has a simple structure and is easy to use, improving the efficiency of AR glasses waveguide testing and reducing testing costs.
