Embodiment Construction

[0025] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as Figure 1-6 As shown, the single-channel iris detection device of the present invention includes a housing 1, and the housing 1 is provided with a collection window 12 for passing an iris image. When the iris of the human eye is collected, the human eye is close to the collection window 12, and the iris images of both eyes enter the device through the collection window 12 respectively.

[0027] A detecting device and an illuminating device are respectively arranged inside the casing 1 . Wherein, the detection device includes a camera board 2 on which an image sensor 21 for image acquisition is arranged. The front end of the image sensor 21 is provided with an objective lens 3 and an infrared filter 4 in sequence.

[0028] The iris images of both eyes passed through the acquisition window 1 pass through the infrared filter 4, ...

Abstract

The invention discloses a single-channel iris detection device, comprising a housing, wherein a collection window for iris image inputting is arranged on the housing; a detection device and an illumination device are respectively arranged inside the housing, the detection device comprises a camera plate, an image sensor for image acquisition is arranged on the camera plate, and an objective lens and an infrared filter are arranged at the front end of the image sensor in turn. Iris images of both eyes coming from the acquisition window pass through the infrared filter and are focused by the objective lens and imaged on the image sensor. The image sensor converts the iris image signals of both eyes into digital signals and transmits them to the camera board for processing. The single-channeliris detection device of the invention adopts a single channel to take photos of iris information of both eyes, and simultaneously captures images of two pairs of iris, which greatly simplifies the system structure and saves device cost.

Description

technical field [0001] The invention relates to single-channel iris detection equipment and belongs to the technical field of optical measurement. Background technique [0002] The iris is the ring-shaped tissue located between the black pupil and the white sclera of the eye, containing intertwined detailed features like spots, filaments, crowns, stripes, etc., which can identify a person. The iris detection equipment confirms the identity of the person by comparing the iris image, which has the characteristics of uniqueness, stability, anti-counterfeiting and non-contact. [0003] Iris recognition technology is to determine the identity of people by comparing the similarity between iris image features. According to the analysis and comparison of various human biometric identification technologies, iris recognition is "the most accurate", "the fastest processing speed" and "the most difficult to forge". This technology is now widely used in finance, customs, security and o...
