Eye imaging system, method and device

Abstract

The invention provides an eye imaging system, method and device. The eye imaging system comprises a light path control module, a light source module, a photosensitive module (33) and a display module(34); the eye imaging system comprises multiple light paths; one light path is generated from the light source module and is projected to an eye (1) via the light path control module, and the light reflected by the eye (1) is projected to the photosensitive module (33) via the light path control module and is displayed on the display module (34). In the eye imaging system, a pupil location technique is introduced, the pupil of the eye is irradiated by the aid of an LED light source, reflected light of the pupil is collected, and working distance is thereby judged accurately.

Description

technical field [0001] The present invention relates to an imaging system, in particular to an eye imaging system, method and device. Background technique [0002] With the continuous advancement and development of science and technology, people pay more attention to the primary screening of eye diseases, especially the screening of fundus diseases such as diabetic retinopathy. Traditional eye imaging systems are bulky, difficult to carry, expensive and unpopular, cumbersome to operate, and difficult to apply to bedridden patients. They are gradually replaced by hand-held eye imaging systems. The design is simple, and there are imaging problems such as uneven illumination, inaccurate working distance, and defocus caused by chromatic aberration, especially the inaccurate working distance. During operation, images are often formed at the front and rear of the working distance, and the resolution of the obtained eye image cannot reach the best. Excellent effect; there is also ...
