Description

Technical Field

[0001] This utility model belongs to the field of AR glasses technology, specifically relating to an AR glasses white balance calibration and detection device. Background Technology

[0002] AR glasses, or Augmented Reality glasses, are high-tech devices that combine computer vision technology and sensors to enhance a user's perception and interaction with the real world by overlaying virtual information onto their field of vision. However, the colors displayed by AR glasses can be affected by ambient light in different environments, such as indoors, outdoors, and in strong or weak light. White balance calibration adjusts the color output of AR glasses to accurately reproduce realistic colors under various lighting conditions, avoiding color casts.

[0003] Problems with existing technology: Currently used white balance calibration and testing devices for AR glasses lack a fixed support mechanism for AR glasses. Therefore, they are prone to shaking and displacement due to external forces during the calibration and testing process, which affects the accuracy of white balance calibration for AR glasses. Utility Model Content

[0004] The purpose of this invention is to provide an AR glasses white balance calibration and testing device. It can automatically adjust the distance between the AR glasses body and the reference mechanism by using a motor and lead screw installed inside the base, thereby improving the performance. Under the action of the clamping component and support frame, it can provide stable fixation for the AR glasses body, thereby avoiding shaking and thus achieving higher white balance calibration and testing accuracy.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] An AR glasses white balance calibration and testing device includes a base and an AR glasses body, wherein a housing is fixedly installed on the top of the base;

[0007] A reference mechanism is provided on the top of the housing, and a placement mechanism is provided on the top of the base;

[0008] The placement mechanism includes a motor and a clamping assembly. The motor drives a lead screw to move the connecting seat linearly, so that the connecting seat drives the support frame to move synchronously through the base plate.

[0009] The clamping assembly includes a fixed plate and a spring. A fixed rod is fixedly installed on one side of the fixed plate, and the spring pushes the clamping plate to move linearly on the surface of the limiting rod.

[0010] The placement mechanism drives the AR glasses body to move linearly, so that the AR glasses body moves through the housing to one side of the reference mechanism, and a light-emitting plate is fixedly installed on the top of the housing.

[0011] The motor is fixedly installed inside the base. The motor drives the lead screw to rotate inside the base. The lead screw is threadedly installed with the connecting seat, so that the connecting seat moves linearly inside the base.

[0012] The support frame and clamping assembly are both fixedly installed on the top of the base plate, and the AR glasses body is snapped onto the top of the support frame.

[0013] Two fixing plates and two clamping plates are provided. The limiting rod is fixedly connected between the two fixing plates. The fixing plate pushes one end of the clamping plate to abut against the AR glasses body.

[0014] The reference mechanism includes a top plate and a cardboard. A mounting frame is fixedly installed on the bottom of the top plate, and a pressure strip is provided on one side of the cardboard.

[0015] The top plate drives the mounting frame to be inserted into the housing, and the pressure strip is used to hold the paper and abut against the mounting frame.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention utilizes a motor and lead screw installed inside the base. Activating the motor causes the lead screw to drive the base plate linearly via a connecting seat. This movement of the base plate, through a support frame, allows the AR glasses to enter the housing for white balance calibration and testing. Simultaneously, a fixing plate is installed on the top of the base plate, and a clamping plate is located on the surface of the fixing rod and abuts against the fixing plate via a spring. Under the action of the spring, the two clamping plates can be pushed towards each other, thus clamping and fixing the AR glasses. Therefore, this invention avoids shaking caused by external forces during white balance calibration and testing of the AR glasses, thereby improving the accuracy of calibration and testing. Furthermore, this invention uses a light-emitting plate installed on the top of the housing to emit light with controllable brightness and color temperature, which, in conjunction with the reference mechanism, enables white balance calibration and testing. Since the cardboard inside the mounting frame is fixed by a pressure strip, and the pressure strip is fixedly installed to the mounting frame, the cardboard can be easily replaced.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, an AR glasses white balance calibration and testing device includes a base 1 and an AR glasses body 5, with a housing 2 fixedly installed on the top of the base 1;

[0026] A reference mechanism 3 is provided on the top of the housing 2, and a placement mechanism 4 is provided on the top of the base 1;

[0027] The placement mechanism 4 includes a motor 41 and a clamping assembly 46. The motor 41 drives the lead screw 42 to drive the connecting seat 43 to move linearly, so that the connecting seat 43 drives the support frame 45 to move synchronously through the base plate 44.

[0028] The clamping assembly 46 includes a fixed plate 461 and a spring 463. A fixed rod 462 is fixedly installed on one side of the fixed plate 461, and the spring 463 pushes the clamping plate 464 to move linearly on the surface of the limiting rod 465.

[0029] See attached document Figure 1 and Figure 2 In this embodiment, the placement mechanism 4 drives the AR glasses body 5 to move linearly, so that the AR glasses body 5 moves through the housing 2 to one side of the reference mechanism 3. The top of the housing 2 is fixedly installed with a light-emitting plate 6.

[0030] In the above embodiment, the AR glasses body 5 can be inserted into the housing 2 by activating the placement mechanism 4. A vertical push-pull baffle is provided at one end of the housing 2. By pushing and pulling upward, the placement mechanism 4 and the AR glasses body 5 can be inserted into the housing 2. Once inside the housing 2, the baffle can be released to seal the housing 2, reducing the impact of external light on white balance calibration and detection.

[0031] Furthermore, the light-emitting plate 6 is installed inside the housing 2, and the light-emitting plate 6 can control the brightness and color temperature through the device's own control system controller. By achieving different brightness and color temperatures, the white balance of the AR glasses body 5 can be detected. And by cooperating with the reference mechanism 3 and the light-emitting plate 6, the white balance of the AR glasses body 5 can be calibrated.

[0032] See attached document Figure 2 , Figure 3 and Figure 4 In this embodiment, the motor 41 is fixedly installed inside the base 1. The motor 41 drives the lead screw 42 to rotate inside the base 1. The lead screw 42 is threadedly installed with the connecting seat 43, so that the connecting seat 43 moves linearly inside the base 1.

[0033] In the above embodiment, since the base plate 44 is threadedly installed to the lead screw 42 via the connecting seat 43, when the starting motor 41 drives the lead screw 42 to rotate, the connecting seat 43 can drive the base plate 44 to slide linearly on the top of the base 1.

[0034] Specifically, since the support frame 45 and the clamping assembly 46 are both fixedly installed on the top of the base plate 44, and the AR glasses body 5 is snapped onto the top of the support frame 45, when the base plate 44 moves, the support frame 45 and the clamping assembly 46 can drive the AR glasses body 5 to move synchronously and enter the interior of the housing 2 for white balance calibration and testing.

[0035] There are two fixing plates 461 and two clamping plates 464. The fixing plates 461 are fixedly installed with the base plate 44, and the limiting rod 465 is fixedly connected between the two fixing plates 461. The fixing plates 461 push one end of the clamping plate 464 to abut against the AR glasses body 5. Therefore, under the reaction force of the spring 463, the clamping plate 464 can clamp and fix the AR glasses body 5, thereby making the AR glasses body 5 more stable.

[0036] See attached document Figure 1 and Figure 5 In this embodiment, the reference mechanism 3 includes a top plate 31 and a cardboard 33. A mounting frame 32 is fixedly installed at the bottom of the top plate 31, and a pressure strip 34 is provided on one side of the cardboard 33.

[0037] In the above embodiment, the top plate 31 can drive the mounting frame 32 to be inserted into the housing 2, while the pressure strip 34 is used to abut the paper 33 against the mounting frame 32. The pressure strip 34 is fixedly installed with the mounting frame 32, so the paper 33 can be easily replaced by removing the pressure strip 34.

[0038] Based on the above structure, the cardboard 33 is a white object, and the area of ​​this white object in the image captured by the AR glasses 5 can be used as a reference standard. By analyzing the RGB values ​​of this area, its color deviation under the current ambient light is determined, and this is used as a basis for calibrating the white balance.

[0039] The working principle of this utility model is as follows: After the AR glasses body 5 is placed on the top of the support frame 45, the clamping plate 464 is pulled to both sides, and the clamping plate 464 compresses the spring 463. After the AR glasses body 5 is placed between the two clamping plates 464, the clamping plate 464 is released. Under the reaction force of the spring 463, the clamping plate 464 clamps and fixes the AR glasses body 5. Then, the motor 41 is started to drive the lead screw 42 to rotate. Since the base plate 44 is threaded to the lead screw 42 through the connecting seat 43, the base plate 44 can drive the AR glasses body 5 to move into the housing 2 to the set position through the support frame 45 and the clamping assembly 46. Then, the card 33 can be placed inside the mounting frame 32 and fixed by the pressure strip 34. Then, the reference mechanism 3 is inserted into the housing 2, and the light-emitting plate 6 is activated to emit the set brightness and color temperature. With the cooperation of the card 33 and the setting of the background system, the white balance calibration and detection of the AR glasses body 5 can be realized. The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
