Method for examining opto-kinetic reflex and ocular kinetic reflex using virtual vision target

Abstract

A visual-eye movement reflex examination method by utilizing a virtual visual target comprises the following steps: 1) a virtual visual target image for visual stimulation is displayed by a virtual visual target optical display system; 2) an eyeball movement image of a detected person caused by the virtual visual target image is photographed by an eyeball movement image collection system; 3) the eyeball movement image is processed by an image processing module, thus forming a curve of the position of a pupil which is changing with the time; the visual-eye movement reflex examination method by utilizing the virtual visual target of the invention can facilitate the vestibular detection.

Description

technical field [0001] The invention relates to an eye movement inspection method, in particular to a visual-eye movement reflex inspection method using a virtual visual target. Background technique [0002] Visual-eye movement reflex examination is an important means for neurology, ophthalmology, otology, etc. to evaluate eye movement and related neuromodulation functions. [0003] At present, eye movement detection methods mainly stimulate eye movement through light-emitting diode matrix or direct projection methods. These methods have the following disadvantages: ① need to configure a huge peripheral target device, such as a cylindrical test room with a radius of about 1 meter , mirrors, motors, etc. Through the cooperation of these auxiliary equipment, the visual stimulation images that induce eye movement can be produced to test the vestibular function. But no matter utilize light-emitting diode matrix form or direct projection, owing to must be equipped with equipment...

Problems solved by technology

[0003] At present, eye movement detection methods mainly stimulate eye movement through light-emitting diode matrix or direct projection methods. These methods have the following disadvantages: ① need to configure a huge peripheral target device, such as a cylindrical test room with a radius of about 1 meter , mirrors, motors, etc., through the cooperation of these auxiliary equipment, the visual stimulus images that induce eye movement can be produced to test the vestibular function

But no matter utilize light-emitting diode matrix form or direct projection, owing to must be equipped with equipment such as above-mentioned test room, and test room can not be reduced further, otherwise will influence detection result, like this, will inevitably lead to utilize the peripheral visual target equipment of the device of existing method It is bulky, not only takes up a lot of space, but also requires specialized personnel for special installation. It needs to occupy a certain amount of space and carry out certain infrastructure installations when equipped. After installation, it cannot be carried or moved casually. It is not suitable for outdoor and mobile tests. place, which not only brings great inconvenience to popularization and use, but also is not conducive to the detection of vestibular function anytime and anywhere; ② using the existing methods of huge peripheral visual target equipment in the process of use, its various parts will inevitably produce mechanical wear, affect its service life; ③ most of the inspection equipment using the existing methods are imported from abroad, which is not only inconvenient to maintain but also very expensive; ④ during the use of the inspection equipment using the existing methods, its mechanical parts such as motors will generate noise, and the To a certain extent, it will affect the tested personnel and affect the detection accuracy
