Embodiment Construction

[0015] The embodiments of the eye parameter detection device of the present invention will be described in detail below with reference to the drawings.

[0016] The eye is one of the most important organs of people, and it is also the sensory organ that makes people feel the discomfort or disease the most.

[0017] The visual organs of the human eye include the eyeball, visual pathway and appendages. The shape of the human eye is close to a spherical shape and is called an eyeball. The eyeball wall is a layer of tissue that surrounds the eyeball and consists of the sclera, choroid, and retina. The eyeball wall can be divided into three layers from the outside to the inside: fibrous membrane, pigment membrane, and retina. The fibrous membrane is composed of fibrous tissue, which is hard, tough and elastic, has a protective effect on the eyeball, and can maintain the shape of the eyeball, like an egg shell. The fibrous membrane can be divided into cornea, sclera and limbus cornea....

Abstract

The invention relates to eye parameter detection equipment which comprises a high-definition camera, an image detection device and a single chip computer AT89C51, wherein the high-definition camera is used for shooting the face of a detected person so as to obtain a detected face image, the image detection device is connected with the high-definition camera and is used for performing image processing on the detected face image, the single chip computer is connected with the image detection device, and is used for determining a plurality of eye parameters based on the image processing results of the image detection device, and the plurality of eye parameters include a pupil position and a palpebra superior and palpebra inferior distance. Through the eye parameter detection equipment, the plurality of eye parameters of the detected person can be fast and accurately detected, and thus a relatively large quantity of valuable reference data can be providing for judgment on the fatigue state judgment, identity recognition or image retrieval of subsequent detected persons.

Description

Technical field [0001] The invention relates to the field of image processing, in particular to an eye parameter detection device. Background technique [0002] The recognition of people’s eye features has a wide range of applications. For example, by detecting the distance between the upper and lower eyelids, people’s fatigue status can be judged. At the same time, due to the high degree of recognition of eye features, the extracted eye features can be used for identity recognition Or image retrieval. [0003] There are basically two eye feature recognition schemes in the prior art: (1) Using electrooculogram and electromyography to measure the opening and closing of the eyes and the position of the eyeball; (2) Using a camera to photograph the detected eyes under natural light The image of the person's eyes is then used to extract various features of the eyes by image processing. Both of these two identification methods have certain shortcomings: the former requires electrodes ...
