FIG. 1 shows a schematic diagram of a virtual reality device display quality detection system 100, according to one embodiment of the invention. As shown in fig. 1, the system 100 includes at least one inspection signal source 110, an inspection control device 120, a three-axis controllably movable turret 130, and a plurality of inspection devices 140. The detection signal source 110 is connected to the virtual reality device to be detected and the detection control device 120, the detection control device 120 is connected to the three-axis controllable motion turntable 130 and the plurality of detection devices 140, and the virtual reality device to be detected is fixed on the three-axis controllable motion turntable 130 so as to rotate along with the three-axis controllable motion turntable.
According to the embodiment of the present invention, the detection signal source 110 can output a dedicated detection signal pattern and detection audio. The detection control device 120 is configured to complete communication between the plurality of detection devices 140, and generate corresponding control instructions to the detection signal source 110 and the plurality of detection devices 140 according to the detection items. The plurality of detection devices 140 includes a bright color detection device 142, an audio analysis device 144, a photoelectric conversion capture device 146, and a plurality of capture devices 148, each for performing a different detection item related to the display quality of the virtual reality device. Optionally, the detection items include screen display detection, audio detection, and system delay detection. According to an embodiment of the present invention, the bright color detection device 142 and the photoelectric conversion capture device 146 are used for executing test contents related to screen display detection, the audio analysis device 144 is used for executing test contents related to audio detection, and the plurality of shooting devices 148 are used for capturing the screen display contents of the virtual reality device to be tested and the movement axis corresponding scales of the three-axis controllable movement turntable 130 from multiple angles and multiple directions in the system delay detection.
According to an embodiment of the invention, the detection control means 120 may be configured as a module arranged on a computing device, for example comprising a system memory and one or more processors, the communication between the system memory and the processors being realized via a data bus. The detection control device 120 includes at least: a connection management unit 122, a judgment unit 124, and a control unit 126, as shown in fig. 1. In addition, the detection control device 120 may further include a touch display screen or physical keys (e.g., buttons, knobs, etc.) for receiving input and output display of the tester, which is not limited by the invention.
Fig. 2 shows an interactive flowchart of a method 200 for detecting display quality of a virtual reality device according to an embodiment of the invention. The following describes in detail a detection scheme of display quality of a virtual reality device according to an embodiment of the present invention with reference to fig. 1 and 2.
The method 200 begins at step S210, and in response to the detection items input by the tester, the determining unit 124 in the detection control device 120 determines the corresponding detection signals and target detection devices according to the detection items, wherein the target detection devices may be one or more of the detection devices 140, and for convenience of description, any one of the target detection devices is generally referred to by the detection device 140 in fig. 2. Then, the judging unit 124 transmits the judgment result to the control unit 126 coupled thereto, and the control unit 126 generates a control instruction based on the judged detection signal on the one hand and generates a rotation instruction and a detection instruction based on the detection item on the other hand.
According to an embodiment of the present invention, the determination unit 124 of the detection control means determines that the target detection means is a bright color detection device or a photoelectric conversion capture device when the detection item is screen display detection, and thus the control unit 126 generates a detection instruction and instructs the connection management unit 122 to transmit the detection instruction to the bright color detection device or the photoelectric conversion capture device. Similarly, when the detection item is audio detection, the determination unit 124 determines that the target detection apparatus is an audio analysis device, and the control unit 126 generates a detection instruction and instructs the connection management unit 122 to transmit the detection instruction to the audio analysis device. When the detection item is the system delay detection, the determination unit 124 determines that the target detection apparatus is the plurality of photographing apparatuses, and the control unit 126 generates a detection instruction and instructs the connection management unit 122 to transmit the detection instruction to the plurality of photographing apparatuses.
On the other hand, according to still another embodiment of the present invention, the control unit 126 of the detection control apparatus generates a first rotation instruction when the detection item is the screen display detection or the audio detection, and instructs the connection management unit 122 to give the first rotation instruction to the three-axis controllable motion turret 130; similarly, when the detected item is the system delay detection, a second rotation command is generated to the three-axis controllable motion turret 130.
According to one implementation of the present invention, the detection control device 120 stores the corresponding relationship between the detection item, the detection signal, the target monitoring device, the control command, the detection command and the rotation command in association with each other in advance, for example, by using the detection item identifier as a key, and stores parameters such as the detection signal, the target monitoring device, the control command, the detection command and the rotation command in association with each other. In response to a certain detection item, the detection control device 120 can quickly acquire a series of parameters corresponding to the detection item.
Subsequently, in step S220, the connection management unit 122 in the inspection control device 120 transmits a control instruction to the inspection signal source 110. According to the embodiment of the present invention, various detection signals (or detection signal patterns) for detection, such as a full white field signal, a full black field signal, a positioning signal, etc., are stored in advance at the detection signal source 110.
Meanwhile, in step S230, the connection management unit 122 in the detection control device 120 transmits a rotation instruction to the three-axis controllable moving turret 130.
Meanwhile, in step S240, the connection management unit 122 in the detection control device 120 transmits a detection instruction to any one of the detection devices 140.
It should be noted that the execution order of step S230 and step S240 is not limited by the embodiment of the present invention.
After the detection control device 120 sends each instruction, correspondingly, in step S250, after receiving the control instruction, the detection signal source 110 identifies the screen display parameters of the virtual reality device to be tested and generates a corresponding detection signal for the virtual reality device to be tested to display. According to an embodiment of the present invention, the control command includes a description or an indication of the detection signal, and the detection signal source 110 may select a corresponding detection signal from the pre-stored detection signals according to the indication and adjust the detection signal to a detection signal suitable for the screen display of the virtual reality device to be detected. Optionally, the detection signal source 110 generates a detection signal corresponding to the intrinsic resolution and the refresh rate of the virtual reality device to be detected, so as to ensure that the detection signal diagram can be normally input.
According to one embodiment of the present invention, when the detected items are screen display detection such as brightness, color gamut coverage, color display accuracy, etc., the detection signals include a full white field signal, a full red field signal, a full green field signal, a full blue field signal, and a 24-color pure color signal. When the detection item is screen display detection such as a refresh rate, black-and-white response time, etc., the detection signal includes a full white field signal, a periodic full black field, and a full white field switching signal.
When the detection item is audio detection, such as sound quality related detection of sound pressure level, maximum output voltage, harmonic distortion, sound frequency response and the like, the detection signal comprises an audio detection signal in the frequency range of 20Hz to 20000 Hz.
When the detection item is system delay detection, the detection signal is a positioning signal and comprises points or lines which can be used for positioning.
The above description of the detection signal and the detection item is only used as an exemplary description, and in practical application, a corresponding detection signal and detection item use case may be formulated according to test requirements. The invention is not limited in this regard.
Correspondingly, in step S260, after receiving the rotation instruction, the three-axis controllable motion turntable 130 rotates at a constant speed by a predetermined rotation angle and a predetermined rotation speed, and drives the virtual reality device to be tested to rotate together.
As described above, in the embodiment according to the present invention, the rotation command is divided into the first rotation command and the second rotation command. The three-axis controllable motion turntable 130 fixes the virtual reality device to be tested in a static state when receiving the first rotation instruction, and rotates at a constant speed by a preset rotation angle and a preset rotation speed when receiving the second rotation instruction.
That is to say, when the detection item is screen display detection or audio detection, the virtual reality device to be detected does not need to rotate, and the three-axis controllable motion turntable 130 remains stationary at this time. When the detection item is system delay detection, the virtual reality device to be detected needs to keep a rotation state along a certain coordinate axis, and at the moment, the three-axis controllable motion turntable 130 can rotate along a preset rotation angle according to a preset rotation speed.
Accordingly, in step S270, the object detection device 140 executes the measurement content after receiving the detection instruction.
According to one embodiment of the invention, when the detection item is screen display detection such as brightness, color gamut coverage, color display accuracy and the like, the target detection device is a bright color detection device which measures brightness and chromaticity coordinates of a corresponding detection signal at an exit pupil position of the virtual reality device to be detected.
According to one embodiment of the invention, when the detection item is screen display detection such as a refresh rate, a black and white response time and the like, the target detection device is a photoelectric conversion capture device, and the photoelectric conversion capture device measures an electric signal with positive correlation of screen brightness change at the exit pupil position of the virtual reality device to be detected.
According to an embodiment of the present invention, when the detection item is audio detection, such as sound quality related detection of sound pressure level, maximum output voltage, harmonic distortion, sound frequency response, etc., the target detection apparatus is an audio analysis device, and the audio analysis device measures decibels of each channel corresponding to the detection signal.
According to an embodiment of the present invention, when the detection item is system delay detection, the target detection apparatus is a plurality of shooting devices, the plurality of shooting devices shoot synchronously, and a high-speed camera test frame number during shooting can also be set, where the shooting content at least includes screen display content of the virtual reality device to be detected and a scale corresponding to a motion axis of the three-axis controllable motion turntable 130.
Subsequently, in step S280, the object detection device 140 returns the detection data to the detection control device 120, and the detection result is analyzed by the detection control device.
For example, in the screen display detection, the screen brightness is the brightness value when displaying the full white field test signal, the color gamut coverage is the result of the calculation of the chromaticity coordinates when displaying the full red field, full green field, and full blue field test signals, and the color display accuracy is the difference between the chromaticity coordinates and the nominal value when displaying the 24-color pure color signal. Meanwhile, the refresh rate is the period of the waveform of the electric signal when the full white field test signal is displayed, and the black and white response time is the time difference between the waveforms from 10% to 90% at the slope from dark to bright in the waveform of the electric signal when the signal is switched between the full black field and the full white field periodically.
For another example, in the system delay detection, images captured by a plurality of cameras (e.g., high-speed cameras) are sent to the detection control device 120, the time synchronization relationship of the captured contents of the plurality of high-speed cameras is obtained by analyzing the time codes of the captured images, and the waveform of the change of the image motion and the time is obtained by calculating the change rate between two adjacent frames of images, so that the time of the image and the time of the three-axis controllable motion turntable changing at the start and the stop of the detection is obtained, and the system delay is further calculated.
In addition, according to an embodiment of the invention, in the detection process, the distortion of the shot content can be caused by shooting through the lens in a high-speed motion state, so that the contour of a moving object can be more accurately determined by carrying out motion tracking on the shot content, the smear in the collected image is further eliminated, and the interference of the residual image caused by the smear on the detection result is avoided. Optionally, the shot content is subjected to motion tracking by using an optimized Camshift algorithm, and the Camshift algorithm (continuous Adaptive Mean-SHIFT) is an improvement of the Meanshift algorithm, and the basic idea is to perform Meanshift operation on all frames of a video image and take the result of the previous frame as the initial value of the search box of the Meanshift algorithm of the next frame, and so on. And will not be described further herein. It should be noted that the embodiment of the present invention only exemplarily shows one of the algorithms for removing smear by using motion tracking, and other related motion tracking or smear removing algorithms can also be combined with the embodiment of the present invention to complete the system delay detection.
According to the detection scheme of the display quality of the virtual reality equipment, the invention provides a relatively uniform detection system, and the display quality of the virtual reality equipment is detected aiming at detection items related to the user experience quality (such as screen display quality detection, audio display quality detection, system delay detection and the like).

However, the disclosed method should not be interpreted as reflecting an intention that: that the invention as claimed requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment.
