Abstract

The invention provides a VR (Virtual Reality) equipment delay test device based on an optical flow camera, which is used for measuring the delay time between user action input and the display screen switching. The device comprises an optical flow camera module, a motorized turntable, a central processing module, a display module and VR glasses; the optical flow camera module is used for acquiringdisplacement information of a display picture of the VR glasses; the motorized turntable is used for simulating user action output; and the central processing module determines the delay time according to the displacement information and swing information of the turntable, and the display module displays the final delay result. The VR equipment delay test device based on the optical flow camera provided by the invention is characterized in that displacement is measured by utilizing the optical flow camera, and the delay time of the VR glasses is obtained according to a delay time calculation algorithm; and besides, the device can be used for the delay test of VR products.

Description

technical field [0001] The invention relates to the field of image processing and analysis, and more specifically, to a device for measuring delay time of VR equipment. Background technique [0002] With the rise and gradual improvement of virtual reality technology, VR products and VR consumption have gradually entered people's field of vision. VR technology is an emerging technology that combines computer image processing technology and stereo vision display technology. It is fundamentally different from the previous panoramic video and 3D movie display technologies, because it uses computer modeling and rendering of 3D animation, and displays it in real time through head-mounted devices. It focuses more on human-computer interaction and provides users with a Immersive experience. [0003] However, VR products currently have many technical defects that need to be resolved urgently. The most prominent problem at present is that when users use VR products for a long time, ...
