Abstract
Description
Technical Field
[0001] This application relates to the field of accuracy testing technology, and in particular to an accuracy testing method and apparatus. Background Technology
[0002] Currently, head-mounted devices (such as augmented reality (AR) devices / virtual reality (VR) devices) generally need to undergo accuracy testing through motion capture systems. The purpose of this testing is to ensure the accuracy and stability of the device's positioning, tracking, and user experience during use.
[0003] Existing methods for accuracy testing require users to first attach optical markers (such as reflective balls or small lights with light-emitting diodes, LEDs) to a head-mounted device. The user then moves around the test chamber while wearing the device. A motion capture system captures the position of the optical markers using a camera, thus obtaining the head-mounted device's true pose (e.g., tilt angle, rotation angle). Simultaneously, a camera on the head-mounted device captures changes in the field of view in that pose. These changes are then used to calculate the test pose of the head-mounted device. The accuracy of the head-mounted device can then be calculated using both the true and test poses. However, because this method requires the user to move around within the test chamber, the chamber must have sufficient space to accommodate the user and the head-mounted device, resulting in a relatively large test chamber.

[0042] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0043] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0045] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0046] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, the user should consider such a combination of technical solutions to be non-existent and not within the scope of protection claimed in this application.
[0047] Understandably, head-mounted devices (such as augmented reality (AR) devices / virtual reality (VR) devices) generally require accuracy testing through motion capture systems to ensure the accuracy and stability of positioning, tracking, and user experience during use.
[0048] Existing methods for accuracy testing require users to first attach optical markers (such as reflective balls or small lights with light-emitting diodes, LEDs) to a head-mounted device. The user then moves around the test chamber while wearing the device. A motion capture system captures the position of the optical markers using a camera, thus obtaining the head-mounted device's true pose (e.g., tilt angle, rotation angle). Simultaneously, a camera on the head-mounted device captures changes in the field of view in that pose. These changes are then used to calculate the test pose of the head-mounted device. The accuracy of the head-mounted device can then be calculated using both the true and test poses. However, because this method requires the user to move around within the test chamber, the chamber must have sufficient space to accommodate the user and the head-mounted device, resulting in a relatively large test chamber.
[0049] Therefore, to address the aforementioned shortcomings, this embodiment provides an accuracy testing method. An adjustment mechanism is provided to adjust the current pose of the device under test. In practical use, the actual pose of the device under test is first acquired. The adjustment mechanism then adjusts the device according to this actual pose. Next, the current image captured by the device is received, and the current test pose is determined based on this image. Finally, an accuracy test is performed based on the current test pose and the actual pose. Compared to existing methods that require a testing chamber with sufficient space to accommodate the user and the head-mounted device, this embodiment only requires sufficient space to accommodate the adjustment mechanism and the head-mounted device, thus reducing the overall size.
[0050] For ease of understanding, the following is combined with Figures 1 to 6 The accuracy testing method provided in the embodiments of this application will be described in detail.
[0051] Reference Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the accuracy testing method of this application. The first embodiment of the accuracy testing method of this application is presented as follows: Figure 1 As shown, in this embodiment, the accuracy testing method includes an accuracy testing device, which includes an adjustment mechanism for adjusting the current pose of the device under test.
[0052] It should be noted that the accuracy testing method provided in this embodiment can be applied to scenarios where accuracy testing is performed on any device under test, such as head-mounted devices (VR glasses, AR glasses, etc.). Of course, it can also be applied to other devices. This embodiment uses a head-mounted device for illustration.
[0053] It should also be noted that the aforementioned adjustment mechanism can be any mechanism that adjusts the current position of the device under test, such as a robotic arm or a platform with tilting, lifting, and rotating functions. This embodiment does not impose any restrictions on this. Furthermore, in actual use, the device under test can be placed on the adjustment mechanism, and the adjustment mechanism can be used to move the device under test, thereby changing the current position of the device under test (for example, it can move forward, backward, left, right, up, or down).
[0054] As one implementation method, refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of the accuracy testing device in the first embodiment of the accuracy testing method of this application, as shown below. Figure 2 As shown, the above-mentioned adjustment mechanism 1 can be described using a platform 13 that has tilting, lifting and rotating functions. That is, the above-mentioned adjustment mechanism 1 includes: a fixed base 11, a telescopic top rod 12, a platform 13 and a rotating part 14.
[0055] The top of the fixed base 11 is fixedly connected to one end of the telescopic top rod 12. The end of the telescopic top rod 12 away from the fixed base 11 can be fixedly connected to the bottom of the platform 13. The top of the platform 13 can be rotatably connected to the bottom of the rotating part 14. The top of the rotating part 14 can be used to support the device 2 to be tested.
[0056] The number of telescopic top rods 12 can be four, or other numbers; this embodiment does not limit this. The telescopic top rods 12 can extend and retract independently, causing the platform 13 to tilt forward, backward, left, right, or move up and down, thereby causing the device under test 2 to tilt forward, backward, left, right, or move up and down. The rotating part 14 can rotate relative to the platform 13, thereby allowing the device under test 2 to be adjusted to different directions.
[0057] It needs to be emphasized that, Figure 2 This is one implementation of the adjustment mechanism 1. Of course, other adjustment mechanisms 1 that achieve similar functions can also be used, and this embodiment does not limit this. The fixed base 11 described above can be fixed to the ground. Of course, the fixed base 11 can also be replaced with a movable base to achieve the walking and moving function.
[0058] In this embodiment, the above method includes:
[0059] Step S10: Obtain the actual pose of the device under test, and adjust the current pose of the device under test according to the actual pose of the device under test through the adjustment mechanism.
[0060] It is understood that the execution subject of this implementation method can be the processor in the aforementioned accuracy testing device, that is, a processor can be set in the accuracy testing device, and the processor can be connected to the aforementioned adjustment mechanism 1 to control the activity of the adjustment mechanism 1.
[0061] It should be understood that the aforementioned true pose to be tested can be the true pose of the device under test 2. In traditional methods of accuracy testing, the user is usually asked to wear the device under test 2 with optical markers attached and adjust it to the pose to be tested. The current pose of the device under test 2 can be calculated by photographing the position of the optical markers. This current pose can be used as the true pose of the device under test 2. At the same time, the camera on the device under test 2 can be used to photograph the field of view in front of the device under test 2. The virtual pose of the device under test 2 can be calculated based on the photographing results. This virtual pose can be the pose of the device under test 2 calculated under the influence of errors. When the virtual pose is inconsistent with the true pose, it indicates that the accuracy of the device under test 2 does not meet the requirements and needs to be adjusted.
[0062] In this solution, the processor can be pre-set with several real poses to be tested, and the current pose of the device 2 under test can be adjusted to the real poses to be tested by the control adjustment mechanism 1.
[0063] Step S20: Receive the current shooting result of the device under test after adjustment, and determine the current test pose of the device under test based on the current shooting result.
[0064] It should be noted that the aforementioned current shooting result can be the result obtained by shooting the scene in front of the field of view of the device under test 2. The aforementioned current test pose can be the virtual pose of the device under test 2 calculated after shooting by the camera. Therefore, in this embodiment, the device under test 2 can be equipped with a camera, which can be the same as that in the traditional solution, and will not be described in detail in this embodiment.
[0065] In practical use, after the current pose to be tested is adjusted to the actual pose to be tested via the adjustment mechanism 1, the camera of the device under test 2 can capture images of the scene within its field of view and transmit the captured images to the processor. Upon receiving the captured images, the processor can calculate the virtual pose of the device under test 2 based on these images, which serves as the current test pose. It should be emphasized that the specific calculation process can be consistent with traditional calculation processes, and this embodiment will not elaborate on it.
[0066] It should be emphasized that, in the process of obtaining the current test pose, since the device under test 2 can also be equipped with sensors, such as an accelerometer and an angular velocity sensor, the processor can also acquire the acceleration data collected by the accelerometer and the angular velocity data collected by the angular velocity sensor. Based on the acceleration data, angular velocity data and the current shooting results, the current test pose is determined together, thereby improving the accuracy of pose determination.
[0067] Step S30: Perform an accuracy test on the device under test based on the current test pose and the actual pose to be tested.
[0068] After obtaining the current test pose and the actual pose to be tested, the processor can compare the current test pose with the actual pose to be tested, and perform fine measurement tests on the device 2 to be tested based on the comparison results. This process is consistent with the traditional process, and will not be described in detail in this embodiment.
[0069] This embodiment includes an adjustment mechanism 1 to adjust the current pose of the device under test 2. In actual use, the actual pose of the device under test 2 can be acquired first. The adjustment mechanism 1 then adjusts the device under test 2 according to this actual pose. Next, the current image capture result of the device under test 2 is received, and the current test pose of the device under test 2 is determined based on this result. Finally, an accuracy test is performed based on the current test pose and the actual pose. Compared to existing methods that require a test chamber with sufficient space to accommodate the user and the head-mounted device, this embodiment only requires sufficient space to accommodate the adjustment mechanism 1 and the head-mounted device, thus reducing the overall size.
[0070] Meanwhile, since this embodiment eliminates the need for the user to wear the test device 2 with optical markers while moving within the test chamber, labor costs are reduced. Furthermore, while manual movement introduces "human error," this embodiment utilizes the adjustment mechanism 1 to minimize this error. Moreover, traditional methods using optical markers require the user to wear the test device 2 with optical markers beforehand and move within the test chamber for scene calibration, followed by accuracy testing. This embodiment, by eliminating the need for optical markers, avoids this calibration process, thus simplifying the operation.
[0071] Reference Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the accuracy testing method of this application. Based on the first embodiment described above, a second embodiment of the accuracy testing method of this application is proposed.
[0072] Considering that in the above embodiments, when performing accuracy testing, it is necessary to adjust the mechanism 1 to change the different scenes captured by the device under test 2, which still results in a large area being required to provide scenes from different directions, in order to further reduce the size, in this embodiment, referring to... Figure 4 , Figure 4 This is a schematic diagram of a precision testing device in the second embodiment of the precision testing method of this application, as shown below. Figure 4 As shown, in this embodiment, the accuracy testing device further includes a test chamber 3, which includes a chamber body 31 and a display screen 32. The chamber body 31 has a receiving cavity 33 inside, and the device to be tested 2 and the display screen 32 are received in the receiving cavity 33. The display screen 32 is located in front of the field of view of the device to be tested 2. The adjustment mechanism 1 is connected to the chamber body 31.
[0073] It should be noted that the aforementioned compartment 31 can be configured as an arc shape (i.e., Figure 4As shown in the diagram, it can also be configured in other shapes; this embodiment does not limit this, and the aforementioned chamber can be in a closed state. The aforementioned display screen 32 can be fixedly installed with the aforementioned chamber 31, and the display screen 32 can be positioned in a position that the camera of the device under test 2 can capture, that is, in front of the field of view of the aforementioned device under test 2. Furthermore, in this embodiment, the entire test chamber 3 can be placed on the aforementioned rotating part 14, and then the rotating part 14 can drive the entire test chamber 3 to rotate and tilt, thereby driving the device under test 2 inside the test chamber 3 to rotate and tilt.
[0074] It should also be noted that the above-mentioned display screen 32 can be a square screen, and the specific size can be set according to the actual situation. This embodiment does not limit this.
[0075] like Figure 3 As shown, in this embodiment, the step of receiving the adjusted current shooting result of the device under test includes:
[0076] Step S21: Determine the corresponding test screen based on the actual pose to be tested, and display the test screen on the display screen;
[0077] Step S22: Receive the current shooting results of the device under test on the display screen after adjustment.
[0078] It is understandable that the aforementioned test images can be images from which the virtual pose of the device under test 2 is calculated. In this embodiment, the scenes captured by the device under test 2 under different virtual poses can be pre-recorded using the device under test 2 with the required accuracy, forming test images corresponding to different virtual poses. Since the device under test 2 meets the requirements, the test images corresponding to each virtual pose should theoretically be consistent with the images captured under the corresponding real pose of the device under test. Therefore, each real position of the device under test can be bound to the corresponding test image to generate a mapping relationship.
[0079] In actual use, the processor can determine the test image corresponding to the actual pose to be tested based on the pre-generated mapping relationship, and send the test image to the display screen 32 for display. At this time, the camera of the device under test 2 can capture the test image, generate the current capture result, and feed it back to the processor. After receiving the current capture result, the processor can calculate the virtual pose corresponding to the device under test 2 as the current test pose, and finally compare the current test pose with the actual pose to be tested.
[0080] For example, if you want to test the pose of the device under test 2 when it is turned left and looking down, the pose of turning left and looking down can be used as the actual pose to be tested. The control adjustment mechanism 1 adjusts the device under test 2 to the actual pose to be tested and obtains the test screen corresponding to the actual pose to be tested. The test screen is displayed on the display screen 32. Then, the current shooting result of the device under test 2 on the test screen can be received. The current test pose of the device under test 2 can be calculated based on the current shooting result and compared with the actual pose to be tested, thereby completing the accuracy test.
[0081] Furthermore, since this embodiment can directly obtain the actual pose of the device under test 2 and the current test pose, compared with the existing ones, this embodiment does not need to perform data format conversion, trajectory alignment and calculation of errors, etc., simplifying the operation process, and can directly output the accuracy test results.
[0082] Meanwhile, since the test screen is displayed on the display screen 32 in this embodiment, the test screen can be adjusted in real time to achieve accuracy testing in different scenarios, thus improving flexibility.
[0083] Furthermore, considering the adoption Figure 4 The adjustment mechanism 1 may not be able to achieve 360° rotation, therefore refer to Figure 5 , Figure 5 This is another structural schematic diagram of the accuracy testing device in the second embodiment of the accuracy testing method of this application, as shown below. Figure 5 As shown, in this embodiment, the adjustment mechanism 1 includes: a fixed base 11, a first robotic arm 15, a second robotic arm 16, and a third robotic arm 17.
[0084] One end of the first robotic arm 15 is rotatably connected to the fixed base 11, one end of the second robotic arm 16 is rotatably connected to the end of the first robotic arm 15 away from the fixed base 11, one end of the third robotic arm 17 is rotatably connected to the end of the second robotic arm 16 away from the first robotic arm 15, and the end of the third robotic arm 17 away from the second robotic arm 16 is rotatably connected to the chamber 31.
[0085] It should be understood that the aforementioned fixed base 11 can be fixed to the ground, and the end of the first robotic arm 15 near the fixed base 11 can form a first joint. By rotating the first joint, the first robotic arm 15 can rotate horizontally and swing around the first joint within a certain range. The end of the second robotic arm 16 near the first robotic arm 15 has a second joint, through which the second robotic arm 16 can swing around the second joint within a certain range. The end of the third robotic arm 17 near the second robotic arm 16 has a third joint, through which the third robotic arm 17 can swing around the third joint within a certain range.
[0086] Meanwhile, the third robotic arm 17 is provided with a rotating part 14 at one end of the second robotic arm 16. The third robotic arm 17 can be rotatably connected to the chamber 31 through the rotating part 14, thereby realizing the rotation of the chamber 31. It should also be understood that the dimensions of the first robotic arm 15, the second robotic arm 16 and the third robotic arm 17 can be set according to the actual situation, and this embodiment does not impose any restrictions on this.
[0087] Understandably, the processor can pre-store the motion modes of the first robotic arm 15, the second robotic arm 16, the third robotic arm 17, and the rotating part 14 to move the device under test 2 to the actual pose to be tested. In actual use, the processor can first query the corresponding motion modes of the first robotic arm 15, the second robotic arm 16, the third robotic arm 17, and the rotating part 14 based on the actual pose to be tested, and then control the first robotic arm 15, the second robotic arm 16, the third robotic arm 17, and the rotating part 14 to move according to the corresponding motion modes, thereby adjusting the current pose of the device under test 2 to the actual pose to be tested.
[0088] Furthermore, in order to fix the component to be tested within the chamber 31, refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of test chamber 3 in the second embodiment of the accuracy testing method of this application; as shown Figure 6 As shown, in this embodiment, the test chamber 3 further includes a fixing part 4;
[0089] The fixing part 4 is disposed in the receiving cavity 33 and is fixedly connected to the chamber 31 for fixing the device to be tested 2.
[0090] It should be noted that the aforementioned fixing part 4 can be any component used to fix the device 2 under test, such as... Figure 6 As shown, the fixing part 4 in this embodiment can be described using a fixing rod and a head model. One end of the fixing rod can be fixed to the bottom inside the chamber 31, and the other end of the fixing rod can be fixedly connected to the head model, with the eye field of the head model facing the display screen 32. The device under test 2 is fixed to the eye part of the head model, so that the camera of the device under test 2 can capture images of the display screen 32.
[0091] Furthermore, in order to conduct accuracy testing under different environments, continue as follows Figure 6 As shown, in this embodiment, the test chamber 3 further includes a first temperature control component 51;
[0092] The first temperature control component 51 is disposed in the receiving cavity 33 and is used to adjust the temperature in the receiving cavity 33.
[0093] It is understood that the first temperature control component 51 can be any component with temperature acquisition and temperature regulation, such as a temperature sensor, heater and heat sink, or other devices. This embodiment does not limit this.
[0094] It should be understood that the aforementioned first temperature control component 51 can be disposed within the receiving cavity 33, such as... Figure 6 As shown, in this embodiment, the first temperature control component 51 can be specifically set inside the chamber 31 on the side away from the display screen 32. Of course, it can also be in other positions, and can be set according to the actual situation.
[0095] It should also be understood that the aforementioned first temperature control component 51 can also be connected to a processor. In actual use, the processor can receive the internal temperature collected by the first temperature control component 51 and compare it with a preset target internal temperature. Based on the comparison result, the processor controls the first temperature control component 51 to raise or lower the internal temperature. The preset target internal temperature can be set according to actual needs.
[0096] Furthermore, considering that prolonged use of the display screen 32 may result in high heat levels, therefore, continuing as follows... Figure 6 As shown, in this embodiment, the test chamber 3 further includes a second temperature control component 52;
[0097] The second temperature control component 52 is disposed in the receiving cavity 33 and is located close to the display screen 32. The second temperature control component 52 is used to dissipate heat from the display screen 32.
[0098] It should be noted that the second temperature control component 52 can be any component with temperature acquisition and temperature regulation capabilities, such as a temperature sensor, heater, and radiator. Of course, it can also be other devices, and this embodiment does not limit it.
[0099] It should also be noted that, in order to accurately collect the temperature of the display screen 32, the second temperature control component 52 in this embodiment can be located inside the chamber 31, close to the display screen 32. Simultaneously, the second temperature control component 52 can also be connected to the processor. Therefore, in actual use, the processor can receive the temperature of the display screen 32 collected by the second temperature control component 52 and compare it with a preset target temperature of the display screen 32. Based on the comparison result, the processor controls the second temperature control component 52 to raise or lower the temperature of the display screen 32. The specific preset target temperature of the display screen 32 can be set according to actual needs.
[0100] Furthermore, in order to achieve accurate testing under different humidity conditions, we continue as follows: Figure 6 As shown, in this embodiment, the test chamber 3 further includes a humidity control component 6;
[0101] The humidity control component 6 is disposed inside the receiving cavity 33 and is used to adjust the humidity inside the receiving cavity 33.
[0102] It is understood that the aforementioned humidity control component 6 can be a component with humidity acquisition and humidity regulation functions, such as a component with a humidity sensor, humidifier and dryer, and this embodiment does not limit it.
[0103] It is also understandable that, in order to improve the efficiency of humidity regulation, such as Figure 6 As shown, this embodiment can be provided with two humidity control components 6, which can be respectively set on the side of the chamber away from the display screen 32, and respectively located at both ends of the first temperature control component 51. Of course, they can also be in other positions, and this embodiment does not limit them.
[0104] The aforementioned humidity control component 6 can also be connected to a processor. In actual use, the processor can receive the humidity inside the chamber collected by the humidity control component 6 and compare it with the preset target humidity inside the chamber. Based on the comparison result, the processor controls the humidity control component 6 to humidify or dry the chamber. The preset target humidity inside the chamber can be set according to actual needs.
[0105] Furthermore, in order to achieve accurate measurements under sufficient light intensity, we continue as follows: Figure 6 As shown, in this embodiment, the test chamber 3 further includes a lighting component 7;
[0106] The lighting component 7 is disposed within the receiving cavity 33 and is used to adjust the brightness within the receiving cavity 33.
[0107] It should be understood that the lighting component 7 described above can be any component with light intensity acquisition function and light intensity adjustment function, such as a component with light intensity sensor and LED light, and this embodiment does not limit it.
[0108] And to ensure sufficient light inside the warehouse, such as Figure 6 As shown, this embodiment can be provided with two lighting components 7, which can be respectively set at the top and bottom of the compartment 31. Of course, they can also be in other positions, and this embodiment does not limit them.
[0109] The aforementioned lighting component 7 can also be connected to a processor. In actual use, the processor can receive the light intensity inside the chamber collected by the lighting component 7 and compare it with a preset target light intensity inside the chamber. When the light intensity inside the chamber is lower than the preset target light intensity, the processor controls the lighting component 7 to emit light. This preset target light intensity can be set according to actual needs. Furthermore, this embodiment can also simulate test conditions under different natural light environments using the aforementioned lighting component 7.
[0110] In addition, to achieve the above objectives, this application embodiment also provides an accuracy testing device, which includes: a processor and an adjustment mechanism 1;

[0113] This embodiment includes an adjustment mechanism 1 to adjust the current pose of the device under test 2. In actual use, the actual pose of the device under test 2 can be acquired first. The adjustment mechanism 1 then adjusts the device under test 2 according to this actual pose. Next, the current image capture result of the device under test 2 is received, and the current test pose of the device under test 2 is determined based on this result. Finally, an accuracy test is performed based on the current test pose and the actual pose. Compared to existing methods that require a test chamber with sufficient space to accommodate the user and the head-mounted device, this embodiment only requires sufficient space to accommodate the adjustment mechanism 1 and the head-mounted device, thus reducing the overall size.
