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.
