In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] like Figures 1 to 2 As shown, an embodiment of the present invention provides a camera and inertial sensor collaborative testing device, which includes a rotating platform 101 and a picture card assembly 401. The rotating platform 101 is used to detect the inertial sensor in the VR device, and the picture card assembly 401 is used to detect the camera in the VR device. At the same time, the rotating platform 101 and the picture card assembly 401 cooperate with each other to comprehensively detect the matching degree between the inertial sensor and the camera.

[0036] like Figure 3 As shown, the rotating platform 101 is capable of three degrees of freedom rotation. The VR device is fixed on the rotating platform 101 and rotates along with the rotating platform 101. During the rotation process, the VR device has three rotation angles and rotation speeds. The actual rotation angle and rotation speed of the VR device are consistent with those of the rotating platform 101 and are manually set by the staff. At the same time, the inertial sensor in the VR device can detect the rotation angle and rotation speed to be verified, and compare the verification value with the set value to perform inertial sensor testing.

[0037] The rotating platform 101 includes a first base 102, a first rotating assembly, and a second rotating assembly. The first rotating assembly can rotate relative to the first base 102, and the second rotating assembly can rotate relative to the first rotating assembly to form a rotation with two degrees of freedom. Furthermore, the first rotating assembly includes two first support plates 103 and a first connecting component. The two first support plates 103 are arranged side by side, and the first connecting component is located between the two first support plates 103. The two first support plates 103 are connected to each other by the first connecting component to form a whole. Figure 4 As shown, the first support piece 103 includes a first horizontal portion 201, a first extension portion 202, and a second extension portion 203. The first extension portion 202 and the second extension portion 203 are located at opposite ends of the first horizontal portion 201. The first horizontal portion 201 and the first extension portion 202 are bent at their connection locations, and the first horizontal portion 201 and the second extension portion 203 are bent at their connection locations. It is understood that the first horizontal portion 201 and the first extension portion 202 are angled, and the first horizontal portion 201 and the second extension portion 203 are angled. The first horizontal portion 201, the first extension portion 202, and the second extension portion 203 enclose an open first accommodating area. The reduced number of connecting structures between the two first support pieces 103 contributes to a lighter weight of the first rotating assembly.

[0038] A first motor 204 is provided on the first base 102 , and an output end of the first motor 204 is connected to the first connecting component. It can be understood that the first motor 204 can drive the first rotating assembly to rotate relative to the first base 102 .

[0039] The second rotating assembly is located in the first accommodating area, which is beneficial to reducing the overall volume of the rotating platform 101. The second rotating assembly includes two second supporting plates 104 and a second connecting component. The two second supporting plates 104 are arranged side by side, and the second connecting component is located between the two second supporting plates 104. The two second supporting plates 104 are connected to each other through the second connecting component to form a whole. Figure 5 As shown, the second support piece 104 includes a second horizontal portion 205, a third extension portion 206, and a fourth extension portion 207. The third extension portion 206 and the fourth extension portion 207 are respectively located at the two ends of the second horizontal portion 205. The position where the second horizontal portion 205 is connected to the third extension portion 206 is bent, and the position where the second horizontal portion 205 is connected to the fourth extension portion 207 is bent. It can be understood that the second horizontal portion 205 is at an angle to the third extension portion 206, and the second horizontal portion 205 is at an angle to the fourth extension portion 207. The second horizontal portion 205, the third extension portion 206, and the fourth extension portion 207 form an open second accommodating area.

[0040] Furthermore, a second motor 208 is provided on the first extension portion 202. The second motor 208 is located between the first extension portion 202 and the third extension portion 206. The output end of the second motor 208 is connected to the third extension portion 206. Driven by the motor, the second support plate 104 can rotate relative to the first rotating assembly, that is, the second rotating assembly rotates relative to the first rotating assembly. During the rotation process, the second rotating assembly gradually moves out of the range of the first accommodating area, allowing the VR device to rotate with a second degree of freedom. To ensure smooth rotation of the second rotating assembly relative to the first rotating assembly, the fourth extension portion 207 is rotationally connected to the second extension portion 203. It is understood that the position of the rotation axis of the fourth extension portion 207 and the second extension portion 203 is approximately aligned with the output shaft of the second motor 208.

[0041] Among them, a third motor 209 is provided on the second connecting component, the output shaft of the third motor 209 is connected to the second base 105, and the VR device is connected to the second base 105. When the third motor 209 rotates, the VR device can rotate relative to the second rotating component, thereby forming the third degree of freedom of rotation of the VR device.

[0042] In some examples, a sliding seat 301 and a screw rod 302 are connected to the bottom of the first base 102. The bottom of the sliding seat 301 is provided with a threaded hole structure, and the screw rod 302 engages with and passes through the threaded hole structure. When the screw rod 302 rotates, the sliding seat 301 can move along the direction of the screw rod 302, thereby adjusting the overall position of the rotating platform 101, facilitating the alignment of the VR device with the image card assembly 401, improving the positioning flexibility of the VR device, and facilitating comprehensive testing.

[0043] In some examples, a plurality of anti-seismic supports 305 are provided at the bottom of the first base 102. Specifically, four anti-seismic supports 305 are provided, each located at an angle of the first base 102. The anti-seismic supports 305 are connected to the top of the sliding base 301 via fasteners, ensuring the overall position stability of the rotating platform 101 and preventing horizontal relative movement between the rotating platform 101 and the sliding base 301. The anti-seismic supports 305 can enhance the stability of the rotating platform 101. When external vibrations occur, the anti-seismic supports 305 will buffer the external vibrations, preventing the external vibrations from being directly transmitted to the rotating platform 101 and affecting the detection results.

[0044] In some examples, a fixed seat 303 is provided at the bottom of the sliding seat 301. The fixed seat 303 is used to support the sliding seat 301 and, at the same time, facilitate the fixing of the position of the screw rod 302. Specifically, a receiving groove is provided in the middle of the fixed seat 303, and the screw rod 302 is located in the receiving groove. It can be understood that the two ends of the screw rod 302 are rotatably connected to the fixed seat 303, and the rotation of the screw rod 302 is not affected while ensuring the position of the screw rod 302. Furthermore, to ensure that the sliding seat 301 can move along the direction of the screw rod 302 and prevent the sliding seat 301 from rotating, a slide rail 304 is provided on the top of the fixed seat 303, and a recessed structure is provided at the bottom of the sliding seat 301. The slide rail 304 is embedded in the recessed structure, further limiting the travel direction of the sliding seat 301.

[0045] In some examples, the camera and inertial sensor collaborative testing equipment further includes a frame structure for supporting the rotating platform 101, providing a certain height for the transmission platform to facilitate operation by a worker in a standing position. Specifically, a crossbeam is provided in the middle of the frame structure, and the fixing seat 303 is connected to the top of the crossbeam.

[0046] In some examples, a reinforcing plate 106 is provided between the two first support plates 103 , and a reinforcing plate 106 is provided between the two second support plates 104 . The reinforcing plate 106 is used to further connect the two first support plates 103 and the two second support plates 104 to ensure the structural stability of the first rotating assembly and the second rotating assembly.

[0047] like Figures 6 and 7 As shown, the chart assembly 401 is horizontally arranged above the rotating platform 101, and a certain distance is maintained between the chart assembly 401 and the rotating platform 101 to avoid affecting the posture and position change of the rotating platform 101. Furthermore, the chart assembly 401 includes a chart body.

[0048] In some examples, the image card assembly 401 also includes a substrate 402 and a light source 403. The light source 403 is fixedly connected to the substrate 402. Specifically, the light source 403 uses a parallel light source 403. The parallel light source 403 irradiates light to the image card body, so that the VR device can capture the pattern on the image card body. In order to expose the image card body within the field of view of the VR device, a hollow portion is provided on the substrate 402. The image card body is within the range of the hollow portion, and it is ensured that the light emitted by the parallel light source 403 can pass through the hollow portion to reach the VR device.

[0049] In some examples, the chart assembly 401 further includes at least two light-transmitting panels 404, each arranged side by side and maintained horizontally. A fixing structure 405 is provided at the edge of the hollow portion, which is used to position the light-transmitting panels 404. Specifically, multiple fixing structures 405 are provided, each having a recessed portion. The edges of the light-transmitting panels 404 can fit into each recessed portion, thereby supporting the light-transmitting panels 404. The chart body is positioned between the light-transmitting panels 404, maintaining a flat surface. Adjusting the position of the light-transmitting panels 404 can adjust the position of the chart body, facilitating operation.

[0050] In some examples, a portion of the fixed structure 405 is fixed to the base plate 402 by fasteners, thereby defining the extreme position of the light-transmitting plate 404; another portion of the fixed structure 405 can produce horizontal displacement at the edge of the hollow portion, thereby fine-tuning the position of the light-transmitting plate 404 to accommodate camera detection of the VR device. Specifically, a horizontal adjustment bracket 501 and a horizontal adjustment bolt 502 are provided at the position of the fixed structure 405. The horizontal adjustment bolt 502 passes through the horizontal adjustment bracket 501, and the end of the horizontal adjustment bolt 502 abuts against the movable fixed structure 405. As the horizontal adjustment bolt 502 is screwed in, the end of the horizontal adjustment bolt 502 gradually applies force to the fixed structure 405, thereby fine-tuning the position of the light-transmitting plate 404, that is, fine-tuning the position of the image card body.

[0051] like Figure 8 As shown, in some examples, the camera and inertial sensor collaborative testing device further includes a housing 503, with the rotating platform 101 and the image card assembly 401 both located within the housing 503. Specifically, the image card assembly 401 is located at the top of the housing 503. Several vertical adjustment brackets 504 are provided on the inner wall of the housing 503. The image card assembly 401 is disposed on the vertical adjustment brackets 504, thereby suspending the image card assembly 401 within the housing 503. Vertical adjustment bolts 505 are provided on the vertical adjustment brackets 504. The vertical adjustment bolts 505 pass through the vertical adjustment brackets 504 and the base plate 402. The vertical adjustment bolts 505 are tightened with nuts 506 to prevent relative movement between the vertical adjustment bolts 505 and the vertical adjustment brackets 504 without hindering relative rotation. Nuts 506 are provided at the positions where the vertical adjustment bolt 505 is inserted into the base plate 402 and the positions where it passes through the base plate 402. The two nuts 506 clamp the base plate 402. During the rotation of the vertical adjustment bolt 505, the height of the corresponding position of the base plate 402 can be fine-tuned, thereby ensuring that the chart body is always in a horizontal state, which is conducive to improving the detection accuracy.

[0052] During use, by controlling the rotation angle and speed of the three axes, the rotation trajectory and equivalent of the VR device can be obtained. The built-in inertial sensor of the product will also provide corresponding data feedback during the rotation process. The two sets of data are then compared and calibrated to calibrate the parameters and accuracy of the built-in inertial sensor of the VR device.

[0053] Furthermore, the light source 403 is fixed to the base plate 402, and the chart body is sandwiched between the light-transmitting plates 404, forming the chart assembly 401. The light-transmitting plates 404 and the chart body are first placed roughly in the center of the base plate 402. The horizontal adjustment bolts 502 are then used to fine-tune the chart body so that it is located exactly in the center of the base plate 402. The calibration fixture is then used to calibrate the chart body. After the position is adjusted, the position of the fixing structure 405 is restrained by fasteners to maintain the adjusted position of the chart body. Finally, the vertical adjustment bolts 505 are used to fine-tune the level of the chart body, allowing for camera testing or coordinated testing of the camera and inertial sensor.
