- the mirror 700 is disposed to be inclined such that the vertical direction has a Z-axis and a predetermined angle ⁇ 6 so as to project the monocular of the user, while the camera 800 is inclined at a predetermined angle ⁇ 5 , ⁇ 6 .
- the photographing direction is set so that the monocular of the user 20 positioned at a predetermined distance range d in front of the half mirror 200 can be photographed through the reflective mirror 700 arranged in the lower position.
- the half mirror 200 and the reflection mirror 700 each have a size of 20mm ⁇ 15mm, which is 1/2 of 40mm ⁇ 30mm, which is the size of a single eye of a general user, and the Y-axis length of the telephoto lens type camera 800 is 30mm.
- the X-axis length of the iris image capture device 10 according to the present invention is 20 mm in width of the reflection mirror 700, the thickness of the other components (first and second light sources, status indicators, etc.) and the housing
- the maximum length is 30mm
- the Y-axis length is 20mm in length of the reflection mirror 200 and 30mm in length of the camera, and the thickness of other components (first and second light sources, status indicators, etc.) and the housing is maximum.
- the length in the Z-axis direction may be 80 mm, and the maximum length may be 30 mm by adding the vertical length 15 mm of the half mirror 200 and the vertical length 15 mm of the reflective mirror 700.
- the iris image capture device 10 may be configured as schematically shown in FIG. 9.
- Half mirror 200, half mirror 200, first light source 300, second light source 400, state indicator 500, direction showing a user staring at iris image capture device 10 Reflector for controlling the angle of the indicator 600, the reflecting mirror 700, the camera 800, the indicator indicator 910 for driving the state indicator 500 and the direction indicator 600, the reflecting mirror 700
- the camera controller 930 is a front surface of the half mirror 200 which is a predetermined distance range for the user 20 to accurately photograph the iris at the up, down, left, and right positions corresponding to the half mirror 200.
- the camera 800 is controlled to photograph the user's monocular.
- the central controller 950 receives the monocular image of the user captured by the camera 800 from the camera controller 930 and captures the iris image based on the received monocular image and a reflection point by infrared light in the monocular image. That is, the central control unit 950 analyzes the positions of the reflection points of the infrared light emitted by the first light source 300 and the second light source 400 in the monocular image of the user captured by the camera 800, and thus the half mirror 200. ) The distance from the front part to the user's monocular can be calculated, and the iris image area can be captured by finding the position of the user's iris and monocular in the photographed monocular image of the user. In this case, the iris capture algorithm may use a variety of methods known in the art.
- the central control unit 950 analyzes the monocular image 1020 of the user captured by the camera 800, as illustrated in FIG. 10, and the first light source 300 or the second light source ( The reflection points of the infrared light irradiated by 400 are not respectively within the optimal monocular image capture area 1040 or iris image capture area 1060, or the user's monocular or iris 1000 is respectively optimal monocular image capture area 1040. Or, if not within the iris image capture area 1060, to direct the user to move the iris image capture device 10 forward and backward to position his monocular within a preset distance range. ) To display the indicator light indicating to the user that the single eye of the user facing the half mirror 200 is not within a preset distance range.
- the central control unit 950 analyzes the monocular image of the user photographed by the camera 800, so that the user is closer to or smaller than the minimum vertical distance d 1 , not within the preset distance range d. If the distance d 2 is located farther away, the indicator controller 910 may be controlled to display the indicator light indicating that the monocular is not located within the preset vertical distance range d through the status indicator 500.
- the central control unit 950 analyzes the monocular image 1020 of the user captured by the camera 800, and the reflection points of the infrared light irradiated by the first light source 300 or the second light source 400 are respectively optimized. If not within the monocular image capture area 1040 or the iris image capture area 1060 of (e.g., the reflection point of the infrared light emitted by the second light source 300 is above or above the optimal iris image capture area 1060). Located at the bottom), allowing the user to move the iris image capture device 10 in the up, down, left and right directions to position the center of his monocular to a point corresponding to the center of the half mirror 200.
