METHOD OF MEASUREMENT OF FAST MOVEMENTS OF EYES AND DEVIATIONS OF SOLID VISION AND DEVICE FOR ITS REALISATION

摘要

FIELD: medicine.;SUBSTANCE: method includes obtaining of the image of eyes, analysis of parameters of eye movement, area choice where the eye pupil moves, finding of figure with size and form corresponding to the sizes and the form of pupil, analysis of movement of the centre of this figure. Thus the eyes are highlighted with an infra-red light source, controlling power of a source of illumination for reception of the most contrast image of eyes. Continuously images of both eyes are obtained by means of two videocameras established opposite to the face of the person. Mutual positions of videocameras are calibrated; the standard of a pupil is formed for its subsequent fast recognition and localisation on the image. Three-dimensional co-ordinates of pupils and view direction in space are defined and results of the analysis are transferred. The first and second videocameras make binocular optoelectronic system. The device also contains a controller, the first and the second blocks of image input, RAM, the first and the second calculators, an infra-red lighter.;EFFECT: application of the given group of inventions allows to increase rate and accuracy of diagnostics of disturbances of solid vision, provides possibility of application of the device in any conditions of illumination, at the expense of exception of dependence of the received image from external illumination.;2 cl, 5 dwg
