When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.
In the application, the horizontal defect of the head-mounted device is caused by manufacturing and installation errors or defects existing in the chip, and when the head-mounted device is in a horizontal initial state, the defect that a detection result of a sensor deviates from an initial zero position occurs. For head-mounted devices, particularly virtual reality devices, horizontal defects can have an impact on imaging performance. Depending on the manner of use, horizontal defects in the head-mounted device that can affect the display effect generally include two situations, namely a pitch angle deviating from an initial zero position in the vertical direction and a roll angle deviating from the initial zero position in the horizontal direction. The deviation in the two directions can cause the picture displayed by the head-mounted device under normal wearing to be inclined, and the viewing experience of the user is affected.
Fig. 1 is a schematic structural diagram of a horizontal defect detection apparatus for a head-mounted device. The application provides a detection device includes, quiet platform 1 moves platform 2 and sets up anchor clamps 3 on moving platform 2, wherein:
the static platform 1 is used for maintaining the horizontal state of the whole detection device; the movable platform 2 can rotate relative to the static platform 1, and the movable platform 2 is in surface contact with the static platform 1; the movable platform 2 is used for driving the head-mounted equipment to be tested 5 to rotate;
the clamp 3 includes a fixing plate 31 and a clamping member 32, a clamping space for fixing the to-be-tested head-mounted device 5 is formed between the fixing plate 31 and the clamping member 32, a wire-passing hole 311 is formed in the fixing plate 31, and the wire-passing hole 311 is used for passing through the data connection line 6, so that the to-be-tested head-mounted device 5 is connected with the data processing device 7 through the data connection line 6.
When the detection device provided by the application is actually used for detection, the static platform 1 is fixed and is in a horizontal static state, and the movable platform 2 is stacked on the static platform 1. The head-mounted device under test 5 is clamped and fixed by the fixing plate 31 and the clamping member 32 in the clamp 3. The clamp 3 is arranged on the top surface of the movable platform 2, and the to-be-tested head-mounted device 5 is in a horizontal state under the combined action of the fixing plate 31, the clamping piece 32 and the top surface of the movable platform 2. For most of the headsets, the rear shells thereof are flat, and the two ends in the transverse direction are provided with the glasses legs or the glasses leg connecting parts, which are arranged at the two ends of the rear shells, accordingly, as shown in fig. 2, in order to ensure that the headset 5 to be tested maintains a good horizontal state, the fixing plate 31 should be attached to the rear shell surface of the headset 5 to be tested, and a hole structure for passing or accommodating the glasses legs and the glasses leg connecting parts is arranged on the fixing plate 31, so that the fixing plate 31 is in contact with the rear shells of the headset 5 to be tested, and the horizontal state of the headset 5 to be tested is maintained.
In actual use, the gravity acceleration measurement value of the to-be-detected head-mounted device 5 in a horizontal state is detected through the gravity sensor built in the to-be-detected head-mounted device 5, the detected gravity acceleration measurement value is transmitted to the data processing device 7 through the data connecting line 6, and the pitch angle and the roll angle are calculated through the data processing device 7, so that whether the to-be-detected head-mounted device 5 has a horizontal defect or not is judged. Because, most of head-mounted devices's data connecting wire interface also sets up on the backshell, consequently in the technical scheme that this application provided, still need set up on fixed plate 31 and be used for through the line hole 311 of data connecting wire 6, the line hole 311 should be enough to hold the data connecting wire joint with the head-mounted devices 5 looks adaptation that awaits measuring. In the actual detection process, the rear shell of the to-be-detected head-mounted device 5 is contacted with the fixing plate 31, the to-be-detected head-mounted device 5 is fixed in the clamping space through the clamping piece 32, and then the to-be-detected head-mounted device 5 is connected with the data processing device 7 through the data connecting line 6 through the wiring hole 311 on the fixing plate 31.
As shown in fig. 5, the movable platform 2 is installed on the top surface of the static platform 1, and can rotate relative to the static platform 1, so that the movable platform 2 drives the to-be-tested head-mounted device 5 to rotate by a preset angle. The static platform 1 transfers the horizontal state to the movable platform 2 through surface contact with the movable platform 2. In order to maintain the horizontal state, a level ruler and a leveling component 12 for adjusting the horizontal state of the static platform 1 can be arranged on the static platform 1.
Further, as shown in fig. 2, at least three leveling members 12 are arranged on the plane of the static platform 1 away from the movable platform 2. The leveling member 12 includes a leveling screw 121 having one end fixed to the stationary platform 1, and a support block 122 screwed to the other end of the leveling screw 121. In this embodiment, one side of the static platform 1, which is far away from the movable platform 2, that is, the bottom surface of the static platform 1, is provided with three leveling parts 12, a supporting block 122 in each leveling part 12 contacts with a table top or a working table top, the supporting block 122 is connected with the static platform 1 by a leveling screw 121, and the supporting block 122 can adjust the position on the leveling screw 121, so as to change the distance between the table top and the static platform 1, and level the static platform 1 by the cooperation of the three leveling parts 12. To further improve the stability of the device, the supporting block 122 may be made of a material with a buffering function, such as rubber, soft plastic, and non-slip foam.
The movable platform 2 can be driven by a motor or manually rotated relative to the static platform 1. The motor driving mode enables the rotating speed of the moving platform to be uniform, detection is facilitated, and the rotating speed in each detection process is the same. However, the motor driving the platform to rotate may bring vibration to the detection process, which may affect the detection result, and a reducer and a transmission mechanism are required, which increases the weight of the whole detection device, making it difficult to maintain and adjust the horizontal state. Therefore, the movable platform 2 can be rotated relative to the static platform 1 in a manual mode, namely, a rotating part for rotating the movable platform 2 is further arranged on the movable platform 2, so that an operator can push the movable platform 2 in a handheld mode to rotate the movable platform 2.
Further, in the technical solution provided by the present application, as shown in fig. 1, the movable platform 2 is stacked on the stationary platform 1, and the stationary platform 1 is a disc-shaped structure with a cylindrical rotating shaft 11 at the center. The movable platform 2 is a disc-shaped structure with a round hole 21 at the center; the rotating shaft 11 passes through the circular hole 21, and the rotating shaft 11 and the circular hole 21 are in clearance fit. In practical use, the top surface of the static platform 1 is used for contacting the movable platform 2 to play a supporting role, therefore, the area of the top surface of the static platform 1 should be ensured to be larger than that of the bottom surface of the movable platform 2, so that the whole bottom surface of the movable platform 2 contacts the top surface of the static platform 1. Such structure not only increases effective support area, can also balance each part of movable platform 2, makes and guarantees enough big face and face contact between movable platform 2 and quiet platform 1, makes movable platform 2 maintain sufficient level state under the support of quiet platform 1.
In addition, the contact surface between the movable platform 2 and the static platform 1 should ensure enough flatness and friction coefficient so as to maintain stability when the two platforms rotate mutually. The flatness of the contact surface can be ensured, and the fluctuation influencing the detection result can be avoided when the movable platform 2 rotates relative to the static platform 1; the friction coefficient of the contact surface is ensured to avoid that the mutual rotating speed between the two platforms is too high, so that the gravity sensor is influenced by the action of centripetal acceleration in the rotating process to influence the measuring result. Obviously, the friction coefficient between the two contact surfaces is not suitable to be too large, because the too rough contact surface can make the movable platform 2 and the static platform 1 difficult to rotate mutually, which brings inconvenience to the detection process; the friction coefficient between the two contact surfaces is not too small, because the too smooth contact surface is easy to cause the rotation change between the platforms too fast, and the acceleration influencing the detection result is formed. For example, in some embodiments provided in the present application, the movable platform 2 and the stationary platform 1 are made of wood material or glass material with a suitable friction coefficient.
In one solution, as shown in fig. 2, the fixed plate 31 is fixed vertically on the movable platform 2. Because most of head-mounted devices are when initial state, the backshell keeps vertical, therefore fixed plate 31 vertical fixation can be when moving platform 2 and be the horizontality on moving platform 2, and fixed plate 31 is vertical state to make the laminating keep vertical state at the head-mounted devices backshell on fixed plate 31, guarantee that head-mounted devices maintains initial state. As shown in fig. 5, two lens holes 312 are further disposed on the fixing plate 31, and the diameter of the lens hole 312 is larger than the outer diameter of the optical lens assembly in the head-mounted device 5 to be tested. The lens hole 312 provided on the fixing plate 31 is used for accommodating a lens module protruding from the rear shell side of the to-be-tested head-mounted device 5. The built-in lens module of the head-mounted device generally protrudes from the surface of the rear shell, so that two lens holes 312 for accommodating the lens module are formed in the fixing plate 31, and the rear shell of the head-mounted device 5 to be tested can be attached to the fixing plate 31, so that the head-mounted device 5 to be tested is kept in a horizontal state. The lens hole 312 is arranged to prevent the lens from directly contacting the fixing plate 31, so that pollution to the lens in the detection process is reduced. In addition, the display screen of the head-mounted device 5 under test is observed from the lens hole 312 to ensure that the head-mounted device 5 under test is in normal operation during the detection process.
In one embodiment, the clamping member 32 includes a pressing plate 321 and a pushing mechanism 320 connected to the pressing plate 321; the pushing mechanism 320 is used for driving the pressing plate 321 to move towards or away from the fixing plate 31; the pressing plate 321 is parallel to the fixing plate 31 and is used for fixing the to-be-tested head-mounted device 5, so that the rear shell surface of the to-be-tested head-mounted device 5 is attached to the fixing plate 31. During actual detection, after the rear shell of the to-be-detected head-mounted device 5 is attached to the fixed plate 31, the pushing mechanism 320 pushes the pressing plate 321 to press the front shell portion of the to-be-detected head-mounted device 5, so that the rear shell of the to-be-detected head-mounted device 5 is closely attached to the fixed plate 31 in the whole detection process. Simultaneously, compress tightly the head-mounted device 5 that awaits measuring through clamp plate 321, can also guarantee that the bottom of the head-mounted device 5 that awaits measuring contacts the top surface of moving platform 2, realize that the head-mounted device 5 that awaits measuring is also in the horizontality on horizontal.

In order to keep the to-be-detected head-mounted device 5 in a horizontal state all the time in the detection process, after the pressing plate 321 reaches a proper position, the pressing plate should be kept unchanged in position, so in this embodiment, a locking knob 322 is further arranged at a position where the handle main body 3251 is hinged to the movable platform 2, and after the handle 325 is pulled to the proper position, the locking knob 322 is screwed to lock the position of the handle main body 3251, so that the situation that the position of the handle 325 changes to cause looseness and damage to the horizontal state of the to-be-detected head-mounted device 5 in the detection process is avoided.
In order to realize the hinge connection between the handle body 3251 and the movable platform 2, a hinge hole protruding from the movable platform 2 should be formed on the movable platform 2.
