[0021] Please see Figures 1-2 As shown in this specific embodiment, a VR / AR module testing device includes: a shooting mechanism 10, a platform mechanism 20, and a base 30. Both the platform mechanism 20 and the shooting mechanism 10 are mounted on the base 30. The platform mechanism 20 is used to support a VR / AR module 40 to be tested, and the shooting mechanism 10 is used to acquire image information of the VR / AR module 40 to be tested. The shooting mechanism 10 includes a fisheye camera assembly 110, a first tilt adjustment slide 120, a second tilt adjustment slide 130, and a support rod 140. The fisheye camera assembly 110 is mounted on the first tilt adjustment slide 120 and can rotate around a first direction via the first tilt adjustment slide 120. The first tilt adjustment slide 120 is mounted on the second tilt adjustment slide 130 and can rotate around a second direction via the second tilt adjustment slide 130. The second tilt adjustment slide 130 is mounted on the base 30 via the support rod 140. The first and second directions are perpendicular to each other. For a better understanding of this application, please refer to... Figures 1 to 4 As shown, the first direction is the X direction, and the second direction is the Y direction. The fisheye camera assembly 110 mounted on the imaging mechanism 10 can capture images of the VR / AR module 40 under test, which is mounted on the stage mechanism 20. Based on the image information, a single OC (Open Center) test is performed on the VR / AR module 40 under test, making the OC test simple and low-cost. The fisheye camera assembly 110 is mounted on the first tilt adjustment slide 120, and the first tilt adjustment slide 120 is mounted on the second tilt adjustment slide 130, allowing the fisheye camera assembly 110 to rotate around the first and second directions. This flexibly adjusts the position of the fisheye camera assembly 110 and the VR / AR module 40 under test, improving detection accuracy and enhancing the applicability of the detection equipment.

[0022] In one embodiment, the fisheye camera assembly 110 includes a first fisheye camera 111, a second fisheye camera 112, and a camera mounting plate 113. Both the first fisheye camera 111 and the second fisheye camera 112 are positioned facing the stage mechanism 20 and mounted on the camera mounting plate 113, which is mounted on a first tilt adjustment slide 120. It should be noted that one fisheye camera corresponds to one VR / AR module 40 under test. By setting multiple fisheye cameras, multiple VR / AR modules 40 under test can be tested simultaneously. Alternatively, a single VR / AR module 40 can be tested, improving the flexibility of the testing equipment.

[0023] In one embodiment, the shooting mechanism 10 further includes a height adjustment slide 150, a second tilt adjustment slide 130 mounted on the height adjustment slide 150, and the height adjustment slide 150 disposed on the support rod 140. The height adjustment slide 150 can slide relative to the support rod 140 in a third direction, which is perpendicular to the first and second directions, i.e., the third direction is perpendicular to the plane formed by the first and second directions. For a clearer understanding of this application, please refer to... Figures 1 to 3 As shown, the third direction is the Z direction. The height between the fisheye camera and the VR / AR module 40 under test can be adjusted as needed, allowing for flexible adjustments based on testing requirements and improving the applicability of the testing equipment.

[0024] In one embodiment, the height adjustment slide 150 includes a support arm 151 with a through hole 152. A support rod 140 passes through the through hole 152, and the support arm 151 can be clamped to the support rod 140 by screws. The support rod 140 is threaded onto the support arm 151, allowing both to slide flexibly in the third direction. The screws secure the support arm 151 and the support rod 140, facilitating the adjustment of their positions and making the fisheye camera assembly 110 easy to adjust.

[0025] In one embodiment, please refer to Figure 4 As shown, the first tilt adjustment slide 120 includes a first rotating platform 121 and a first fixed platform 122. The first rotating platform 121 is rotatably mounted on the first fixed platform 122 about a first direction. The second tilt adjustment slide 130 includes a second rotating platform 131 and a second fixed platform 132. The second rotating platform 131 is rotatably mounted on the second fixed platform 132 about a second direction.

[0026] In one embodiment, please refer to Figure 3As shown, the stage mechanism 20 includes a module placement seat 210, a rotary slide 220, and a planar sliding slide 230. The module placement seat 210 is used to place the VR / AR module 40 under test. The module placement seat 210 is mounted on the rotary slide 220 and can rotate around the optical axis of the fisheye camera assembly 110 via the rotary slide 220. The rotary slide 220 is mounted on the planar sliding slide 230 and can slide in a first direction and a second direction via the planar sliding slide 230. The rotary slide 220 can adjust the rotation angle between the VR / AR module 40 under test and the fisheye camera to ensure that the crosshairs displayed on the VR / AR module 40 under test are located at the center of the fisheye camera, thereby improving detection accuracy. It can be understood that, in order to facilitate the testing of the VR / AR module 40 under test, the crosshairs are displayed on the VR / AR module 40 under test during the testing process, and the imaging mechanism 10 captures the crosshairs to obtain image information of the VR / AR module 40 under test, thereby improving the feasibility of the testing. The planar sliding stage 230 can adjust the position of the VR / AR module 40 under test and the center of the fisheye camera, improving the positioning accuracy of both and ultimately improving the detection accuracy of the detection equipment. Preferably, when the optical axis of the fisheye camera assembly 110 is aligned with the plane formed by the first and second directions, the optical axis is parallel to the third direction.

[0027] In one embodiment, the stage mechanism 20 further includes a guide slide 240 and a guide base 250. The guide slide 240 is disposed on the guide base 250 and can slide relative to the guide base 250 in a first direction or a second direction. A planar sliding slide 230 is mounted on the guide slide 240, and the guide base 250 is mounted on the base 30. The planar sliding slide carrying the VR / AR module 40 to be tested is slidably mounted on the guide slide 240, and by sliding the guide slide 240 in the first direction or the second direction, the module placement seat 210 for carrying the VR / AR module 40 to be tested is moved away from below the shooting mechanism 10, which facilitates the installation of the VR / AR module 40 to be tested into the module placement seat 210 of the stage mechanism, improves assembly efficiency, and avoids interference with the shooting mechanism 10.

[0028] In one embodiment, the module placement base 210 is provided with a first placement slot 211 and a second placement slot 212, which are used to accommodate the VR / AR module 40 to be tested. Installing the VR / AR module 40 to be tested through the first placement slot 211 and the second placement slot 212 improves assembly efficiency and convenience.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
