Aiming at the problem of low resolution

low frame rate

and lack of anti-jamming capability of videonystagmography in benign positional parsmal vertigo（BPPV） diagnosis

a real-time wireless high-speed videonystagmography tracking system is proposed. The system constructs the core control board which can realize highspeed wireless transmission based on ARM Cortex-A7 architecture and 5 G WiFi module

use MIPI camera interface to ensure high-speed video acquisition

using H. 265 high-performance coding technology to achieve video lossless compression

completing the construction of the wireless transmission network through the real-time RTSP network transmission protocol

the terminal receives the nystagmus video through the wireless network

and performs the real-time nystagmus tracking algorithm analysis based on the dark pupil to acquire the nystagmus information. The effect of video resolution and frame rate on system precision and anti-jamming ability of different transmission modes are tested. The experimental results show that the proposed high-speed video-nystagmography tracking system has high precision and strong anti-interference ability

and can accurately obtain nystagmus trajectory

which lay the foundation for the diagnosis of the disease.
