Embodiment 1

[0158] Example 1: Customs clearance system applied to large-scale users

[0159] The invention can be applied to the customs clearance system of large-scale users. An example is as follows: a long-distance iris recognition system is used at a certain customs port to verify the identity of a person. The user presents his ID in front of an access door to show his identity, or uses a card reader to let the computer read out his ID number; then the front gate of the channel opens and people enter the channel; when entering the channel, the user looks ahead and releases Walk slowly, at this time, the clear image of the iris of the person will be automatically collected from the front long distance; if the identification is passed, and it is indeed the person on the certificate, open the back gate of the passage, and the person can walk through the passage at a normal pace; Pass, it indicates that there is a problem with the person's identity, and security personnel need to check and co...

Embodiment 2

[0161] Example 2: Iris recognition system applied to VIPs

[0162] The invention can be used in the iris recognition system of VIPs. The usage process is as follows: At the entrance of a high-level club, visitors need to be identified by iris recognition, but since the guests are more distinguished, in order not to arouse the guests' disgust, it is inconvenient for the equipment to be aimed at the guests to operate, so the club entrance adopts Long-distance iris image recognition device. When the guest enters the hall, when passing through the gate, stay in a fixed position for 3 seconds and look ahead. During this process, a clear image of the iris is captured by a remote collection device 3 meters away and recognized The identity of the guest and the voice of "Mr. XX, welcome." This allows guests to feel the safety measures of the clubhouse, and at the same time makes them very convenient and satisfied.

Abstract

The invention discloses a distant range iris identifying system and a method thereof. The system includes: a camera / long focus lens for shooting eye image; a collecting card; a main control computer for collecting image by controlling the camera / long focus lens through the collecting card; a controllable clouds terrace for controlling the camera / long focus lens raising falling or left and righ rotary set on computer under controlled by the computer; a display / clew device for displaying the image collected by the camera / long focus lens or clewing under controlled by the main control computer; a height test sensor set on an identifying channel top for testing human height; an infrared source set on two sides of the channel door front for supplying light to image shoot; a singlechip control circuit for controlling the height testing sensor and the infrared source working. The system can shoot clear iris image continuously in distant range (beyond three meters) and identify which can increase practicability and enlarge application range for identifying iris.

Description

Technical field [0001] The invention relates to a system and method for iris recognition at a long distance. The invention integrates image processing, pattern recognition, optical technology, automatic control and other technologies, and is applied to the iris recognition direction in the field of biometric recognition. Background technique [0002] Iris recognition technology is one of the current biometric recognition technologies with the highest accuracy and best anti-counterfeiting, and has a broad market application prospect. The steps of iris recognition generally include iris image acquisition, live detection, preprocessing, feature extraction and feature matching. [0003] The current iris technology can achieve fast and accurate identification. For example, the patents of the State Intellectual Property Office of China: 1. Tan Tieniu, Wang Yunhong, Ma Li, "Identity Recognition Method Based on Living Iris", application number: 01144524.6; and 2. Tan Tieniu, Wang Yunhong...
