Embodiment Construction

[0027] The above and other technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0028] refer to figure 1 , the present embodiment provides a portable wireless nystagmus testing instrument, including a spectacle frame assembly 1 and a headband 2 . Wherein, the main body of the frame assembly 1 is similar to the frame of swimming goggles. Adopting this structure is based on portability considerations. Currently, most nystagmometers on the market are constructed similar to VR eyes. In actual use, it is impossible to do other things while wearing the existing nystagmus meter to test nystagmus. Therefore, the acceptance of users in this regard is not ideal. In this embodiment, after the user wears the wireless nystagmus testing instrument, he can do other things whil...

Abstract

The invention provides a medical nystagmus test method, which includes the step of acquiring eyeball movement: respectively acquiring eyeball movement images from lenses with folded angles through two cameras, and tracking the central position of the pupil through an image processing method. And obtain the horizontal nystagmus signal, track another image through the image processing method to track the central position of the pupil and obtain the vertical nystagmus signal; the step of obtaining the nystagmus characteristic parameter: the horizontal nystagmus obtained under different posture states The signal and the longitudinal nystagmus signal are processed to obtain the characteristic parameters of nystagmus; the step of determining the direction of the torsion angle of the nystagmus is: performing horizontal nystagmus polarization on the characteristic parameters of the transverse nystagmus, and performing longitudinal nystagmus characteristic parameters on the longitudinal nystagmus Polarization, to obtain the torsion angle of the nystagmus and determine the direction of the torsion angle of the nystagmus.

Description

technical field [0001] The present invention relates to a medical testing method based on big data processing, and more specifically relates to a medically applicable nystagmus testing method. Background technique [0002] Nystagmus, referred to as nystagmus, is a rhythmic movement of the eyeballs that is not controlled by the mind. Vestibular nystagmus consists of alternating slow and fast phase movements. Congenital nystagmus, also known as congenital essential nystagmus, is a disease with complex manifestations, serious harm, undiscovered etiology and difficult treatment. The onset of the disease is early, and the main clinical manifestation is the regular swing of the eyeball, which can cause amblyopia, side vision and difficulty in fixation, etc., seriously affecting visual function. [0003] At present, nystagmus is often used in medicine to test eye movements. For example, there is a patent document with the publication number CN205548517U disclosing a nystagmus met...
