Abstract

The present invention provides a method for detecting the frame rate of a head-mounted display device, comprising the following steps: fixing the head-mounted display device to a device support, and the device support rotates axially at a preset angular velocity; The angle mark is displayed on the screen of the head-mounted display device, indicating the rotation angle of the head-mounted display device detected by the sensor of the head-mounted display device; Displays the frame rate of the device. The present invention also provides a detection device for the frame rate of the head-mounted display device. The method and device for detecting the frame rate of a head-mounted display device of the present invention can effectively improve the detection efficiency and detection accuracy of the frame rate of the head-mounted display device, and are suitable for detecting the frame rate of a head-mounted virtual reality device.

Description

technical field [0001] The invention relates to the technical fields of computer vision and artificial intelligence, in particular to a method and device for detecting the frame rate of a head-mounted display device. Background technique [0002] Virtual reality technology (Virtual Reality, referred to as VR), through computer graphics, machine vision technology, artificial intelligence technology and other technologies to construct a simulated reality model and realize human-computer interaction, to generate the same feedback information as in the real world, in order to achieve The effect of entering the virtual world enables users to get the same sensory experience as in the real world. [0003] At present, the frame rate is one of the technical parameters that need to be improved in the virtual reality system and equipment. The low frame rate causes discontinuity or distortion of the scene, which makes the virtual environment perceived by users not realistic enough. In...
