The eye point distance measurement assembly 40 is fixedly arranged on the image acquisition assembly 20 and is used to measure the distance and angle between the image acquisition assembly 20 and the measured object. The marquee light assembly 50 is arranged on the device frame 10. The marquee light assembly 50 includes a marquee light box 51 arranged in front of the fixing mechanism 32. The marquee light box 51 is provided with a plurality of test light sources which can be triggered in sequence. The electrical assembly 60 is arranged in the device frame 10. The electrical assembly 60 is electrically connected to the image acquisition assembly 20, the pose adjustment assembly 30, the eye point distance measurement assembly 40, and the marquee light assembly 50 respectively, so as to control the image acquisition assembly 20, the pose adjustment assembly 30, the eye point distance measurement assembly 40, and the marquee light assembly 50 respectively through the electrical assembly 60.
[0042] It can be understood that in the use of the VST effect detection device of the present application, the measured object, i.e. the VR head-mounted device, can be first fixed to the fixing mechanism 32; then the distance and angle between the Pancake end face of the VR head-mounted device and the image acquisition assembly 20 are measured by the eye point distance measuring assembly 40; then the relative pose between the measured object and the image acquisition assembly 20 is adjusted by driving the fixing mechanism 32 to move by the six-axis motion mechanism 31; finally, the various test light sources on the marquee box 51 are triggered in sequence, and the view displayed by the VR head-mounted device is acquired by the image acquisition assembly 20 to realize the delay measurement of the VR head-mounted device in the VST mode.
[0043] Exemplarily, the marquee box 51 of the present application can adopt LED lamps as test light sources.
[0044] In some embodiments, as shown in Figure 4 The image acquisition assembly 20 of the present application can include a camera mounting seat 21, a pair of acquisition cameras 22 and two lenses 23, the camera mounting seat 21 is fixedly arranged on the device frame 10, the pair of acquisition cameras 22 are fixedly arranged on the camera mounting seat 21, and the two lenses 23 are respectively arranged on the acquisition cameras 22, the marquee box 51 is located in front of the acquisition cameras 22, and the acquisition cameras 22 can respectively acquire the left eye display view and the right eye display view of the VR head-mounted device. In this way, the left eye display view and the right eye display view of the VR head-mounted device are respectively acquired by the two acquisition cameras 22 and the lenses 23, which can simulate the effect of human eyes to obtain more accurate test results.
[0045] Exemplarily, the acquisition cameras 22 of the present application can be industrial cameras, and the lenses 23 can be liquid lenses 23.
[0046] In some embodiments, as shown in Figure 5 The eye point distance measuring assembly 40 of the present application can include a guide rail fixing seat 41, a sensor guide rail 42, a sensor fixing seat 43, two displacement sensors 44 and a sensor driving member 45, the sensor guide rail fixing seat 41 is fixedly arranged on the image acquisition assembly 20, the sensor fixing seat 43 is slidably arranged on the sensor guide rail 42, the sensor guide rail 42 is fixedly arranged on the guide rail fixing seat 41, the two displacement sensors 44 are respectively fixedly arranged on the two sides of the sensor fixing seat 43, the sensor driving member 45 is fixedly arranged on the guide rail fixing seat 41 and is drivingly connected to the sensor fixing seat 43, and the displacement sensor 44 is communicatively connected to the six-axis motion mechanism 31. In this way, by driving the sensor fixing seat 43 to slide along the sensor guide rail 42 by the sensor driving member 45, the two displacement sensors 44 can be driven to move to measure the distance and angle between the Pancake end face of the VR head-mounted device and the image acquisition assembly 20. The sensor guide rail 42 can ensure the stability of the movement of the sensor fixing seat 43 to provide more accurate measurement data.
[0047] Exemplarily, the sensor driving member 45 of the present application can be a micro servo cylinder, which can be fixed on the guide rail fixing seat 41 through a micro servo cylinder locking block, and the piston rod of the micro servo cylinder is fixedly connected to the sensor fixing seat 43. When the eye point distance measuring assembly 40 is working, the sensor fixing seat 43 can be pushed outward or pulled inward by the micro servo cylinder, so that the sensor fixing seat 43 slides along the sensor guide rail 42. The displacement sensor 44 can be fixed to the sensor fixing seat 43 through a displacement sensor 44 locking block.
[0048] In some embodiments, as shown in Figure 6 The fixing mechanism 32 of the present application is a head mold arranged on the six-axis motion mechanism 31. The front side of the head mold is provided with a collection port, and the image collection assembly 20 is arranged in the head mold and can collect the view of the measured member through the collection port. In this way, the head mold can cooperate with the two collection cameras 22 to simulate the structure of a human head, which facilitates the assembly of the measured member and can provide more accurate test data.

The marquee light translation driving member 55 is arranged on the fixed frame 52 and is drivingly connected to the marquee light cantilevers 54, so as to drive the marquee light cantilevers 54 to slide along the fixed frame 52. The marquee light cantilevers 54 are connected to the two sides of the marquee light box 51, respectively. In this way, by sliding the marquee light cantilevers 54, the distance between the marquee light box 51 and the image collection assembly 20 can be adjusted, so that the VST effect detection device of the present application can adapt to VR head-mounted devices with different field angles of view. The marquee light translation driving member 55 is controlled by the electrical assembly 60, so that the VST effect detection device of the present application can automatically adjust the distance between the marquee light box 51 and the image collection assembly 20.
[0050] Exemplarily, as shown in Figure 10 The marquee light translation driving member 55 is a linear module fixedly arranged on the fixed frame 52 and located below the marquee light cantilevers 54. The marquee light assembly 50 further includes a floating shaft L plate 57 fixedly arranged on the marquee light cantilevers 54 and a floating shaft fixing plate 58 fixedly connected to the linear module.

The front side of the device frame 10 is provided with a storage compartment. When the VST effect detection device is not working, the marquee box 51 is placed in the storage compartment. This arrangement allows the marquee box 51 to be stored in the storage compartment when the VST effect detection device is not working, thereby reducing the placement space of the device. When the VST effect detection device is working, the marquee rotation drive 56 can drive the marquee box 51 to rotate to the working position, and the distance between the marquee box 51 and the image acquisition component 20 can be adjusted by the marquee translation drive 55.
