System for real-time collection of eyeball movement and head movement

Abstract

The invention discloses a system for real-time collection of eyeball movement and head movement. The systems includes an eye patch body, an eye movement camera system, a light source and fixation targets, wherein the eye patch body is arranged symmetrically and vertically, the eye movement camera system is used for collecting eyeball images of a user, and the light source is used for providing illumination for eyeballs; the fixation targets include a front fixation target, a left front fixation target and a right front fixation target, the fixation targets are arranged separately on bilateralhorizontal semicircular canal planes, left front / right rear semicircular canal planes and right front / left rear semicircular canal planes of the user, and the three fixation targets are fixed to the head of the user, so that head-shaking suppression tests are performed; and the eye movement camera system, the light source and the three fixation targets are installed on the same side of the eye patch body so that eye movement images of the user are collected. The head-shaking suppression tests on different planes of the three pairs of semicircular canals can be achieved simultaneously, the movement positions of the head of the user can be recorded in real time, and the eye movement images of the user are collected.

Description

technical field [0001] The invention relates to the technical field of image acquisition for short-distance testing of eyeball movement information, in particular to a system for real-time collection of eyeball movement and head movement. Background technique [0002] The vestibule is an important system responsible for maintaining the balance of the human body, mainly composed of the peripheral vestibule and the central vestibule. The peripheral vestibule includes three pairs of semicircular canals and otolithic organs. Once any of the three pairs of semicircular canals in the human body is dysfunctional, it will lead to balance dysfunction, and then produce symptoms such as vertigo. Quantitative and qualitative testing of semicircular canal dysfunction is an important basis for doctors in departments related to vertigo diseases such as otolaryngology and neurology to give patients a final diagnosis of the disease. [0003] According to the frequency characteristics of the...

Problems solved by technology

This technical solution is mainly used for nystagmus acquisition in ordinary vestibular function tests such as optokinetic tests and saccade tests; when it is applied to head shake suppression tests (suppression head impulse, SHIMP), the technical limitation of the projection system can only examine a pair of horizontal semicircular canals , failed to achieve the head shake inhibition test of three pairs of semicircular canals in different planes
