Eye image collector

An eye image and acquisition device technology, which is applied in the acquisition/recognition of eyes, instruments, characters and pattern recognition, etc., can solve the problem of affecting the iris recognition results of the eyes, cannot fully guarantee the accuracy and ease of use of the image acquisition process, and the inability to use errors. Eliminate and other problems to achieve the effect of eliminating the difference in pupil distance, stabilizing the zoom movement, and eliminating the use error

Problems solved by technology

However, because the above-mentioned traditional eye image acquisition device fails to provide accurate and quantitative prompt information, and whether the user's position is suitable is judged by the user himself, and the difference between the pupil distance of the user's eyes and the internal and external strabismus, etc. Errors cannot be eliminated
Therefore, the accuracy and ease of use of the image acquisition process cannot be fully guaranteed
At the same time, due to the stimulating effect of visible light on the eyes, the pupils of the eyes contract when the light is strong, otherwise the pupils dilate. The above changes in the pupils will change the shape of the iris texture of the eyes, thus affecting the recognition results of the iris of the eyes
Traditional eye image capture devices also fail to address this issue

Embodiment Construction

[0027] The specific implementation process of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] 1. Device composition and positional relationship

[0029] The device includes, and the device also includes the following parts: an eye image acquisition part, used to collect the user's eye image; a positioning part, which guides the user's eye into the field of view of the eye image acquisition part, and measures the user's eye and eye image acquisition Part distance. The positioning part includes a reflector again; a distance measuring part; an eye image acquisition control part, used to judge whether the user's eyes enter the collection range along the optical axis direction of the eye image acquisition part; an illumination part, in order to provide the user with suitable lighting. The above four components of the positioning component are consolidated in the external housing, wherein the distance measuring componen...

Abstract

A collection device of eye image is prepared for setting reflector at front external surface of externally-set shell, arranging distance measurement component above said reflector and illumination component below said reflector, setting eye image collection component at back of said reflector and setting eye image collection control component in externally-set shell.

Description

technical field [0001] The invention relates to an optical imaging device, in particular to an eye image acquisition device. Background technique [0002] To collect a complete and clear human eye image, it is necessary to limit the six degrees of freedom of the user's eyes relative to the acquisition device in three dimensions, up and down, left and right, and front and back. Therefore, the traditional eye image acquisition device must give a variety of prompt information, and the above information is very Difficult to quantify, it is up to the user to judge whether the position is appropriate based on experience. This causes the eyes to be difficult to locate accurately, and the user has to adjust his position through some complicated prompts provided by the device so that his eyes fall into the collection range of the collection device. Therefore, the main problem is that users must be trained to use the acquisition device correctly, and inexperienced users use it for to...
