Problems solved by technology

[0003] However, the above method needs to convene many testers to carry out double-blind tests. The more the number of testers, the closer the final results are to the real situation, but the higher the test cost is, the test cost and the correctness of the test results will become Proportional
In addition, the test results obtained by using the above test methods are very subjective, and the data cannot be quantified, resulting in low accuracy of the test results

Embodiment 1

[0089] Generate control commands according to preset rotation angles;

[0090] driving the head-mounted display device to rotate according to the control instruction;

[0091] Obtain the angle data of the gyroscope in the head-mounted display device in real time, and when the angle data of the gyroscope in the head-mounted display device changes, send a frame of white image to the head-mounted display device; at the same time, obtain the screen light intensity value of the head-mounted display device in real time through the photosensitive sensor and system time; when the angle data remains unchanged within the preset time range, stop acquiring the screen light intensity value and the system time;

[0092] Generate a light intensity change curve according to the screen light intensity value and the system time;

[0093] Analyzing the light intensity change curve to obtain the system time corresponding to the maximum screen light intensity value and the initial time of the lig...

Embodiment 2

[0096] Generate control commands according to preset rotation angles;

[0097] driving the head-mounted display device to rotate according to the control instruction;

[0098] Obtain the angle data of the gyroscope in the head-mounted display device in real time. When the angle data of the gyroscope in the head-mounted display device changes, send the preset first image to the head-mounted display device and obtain the sending time; at the same time, obtain the head-mounted display in real time through a high-speed camera The screen of the device displays the image and the system time to obtain a second image to form a second image set; when the angle data remains unchanged within a preset time range, stop acquiring the second image;

[0099] sequentially acquiring a second image in the second image set;

[0100] Analyzing the second image, if the second image is the same as the preset first image, acquiring the system time corresponding to the second image; the sending time ...

Embodiment 3

[0101] Such as Figure 5 Shown, embodiment three of the present invention is:

[0102] Preset the rotation angle on the PC side, and generate control commands according to the preset rotation angle;

[0103] The main control board forwards the control commands sent by the PC to the stepper motor driver;

[0104] The stepper motor driver drives the VR head-mounted display device to rotate a preset rotation angle according to the control instruction;

[0105] The PC side sends a frame of white image to the VR head-mounted display device; at the same time, the main control board sends a sampling command to the photosensitive sensor;

[0106] The photosensitive sensor is located directly in front of the screen of the VR head-mounted display device, and obtains the light intensity value of the screen of the VR head-mounted display device according to the sampling command sent by the main control board, and forwards the acquired light intensity value of the screen to the PC termin...

Abstract

The invention relates to the testing field, and particularly relates to a method and a system for testing head-mounted display device performance. When angle data of a gyroscope in the head-mounted display device change, a frame of white image is sent to the head-mounted display device; the screen light intensity value and the system time of the head-mounted display device are acquired in real time; when the angle data remain unchanged in a preset time range, acquisition of the screen light intensity value and the system time is stopped; according to the screen light intensity value and the system time, a light intensity change curve is generated; the light intensity change curve is analyzed to obtain the system time corresponding to the maximum screen light intensity value and the initial time of the light intensity change curve; and the difference between the system time corresponding to the maximum screen light intensity value and the initial time of the light intensity change curve is calculated, and the response time of the head-mounted display device is obtained. The performance of the head-mounted display device is tested automatically, and accurate testing data can be obtained.

Description

technical field [0001] The invention relates to the field of testing, in particular to a performance testing method and system for a head-mounted display device. Background technique [0002] Virtual reality technology is a computer simulation system that can create and experience virtual worlds. It uses a computer to generate a simulated environment, which is an interactive three-dimensional dynamic scene and a system simulation of entity behavior that integrates multi-source information to immerse users in the environment. At present, the sensitivity test of virtual reality head-mounted display devices on the market requires a large number of testers to obtain test results through double-blind tests. Testers experience the same scene by wearing virtual reality head-mounted display devices from different manufacturers. Fill in the questionnaire results, subjectively judge the high + low sensitivity of the virtual reality head display equipment, and then sort the virtual re...
