Embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
The adaptive location iris image capturing system that the utility model provides mainly comprises light fixture 1, distance-measuring equipment 2, video camera (5,6), processor 7 and control parts of motion.Light fixture 1, face video camera 6, iris video camera 5 and distance-measuring equipment 2 are fixed on The Cloud Terrace 8, and 5 optical axises of face video camera 6 and iris video camera remain on a plane in the vertical direction.The alignment lens target 9 of iris video camera 5 and face video camera 6.Computing machine 11 control figure processor 7, controller 10 and driver 12, control The Cloud Terrace 8 by control and drive system 12.
Concrete, the utility model mainly comprises light fixture 1, distance-measuring equipment 2, micro-control unit 3, display 4, iris video camera 5, face video camera 6, digital processing unit 7, The Cloud Terrace 8 and computing machine 11, micro-control unit 3, display 4, iris video camera 5, face video camera 6 are connected with digital processing unit 7 respectively with computing machine 11, and light fixture 1, distance-measuring equipment 2, iris video camera 5 and face video camera 6 are fixed on The Cloud Terrace 8.
Wherein, light fixture 1 is near-infrared LED light source, and display 4 is liquid crystal display.Distance-measuring equipment 2 is connected with micro-control unit 3.Distance-measuring equipment 2 and micro-control unit 3 are set up in parallel, and the optical axis of iris video camera 5 and face video camera 6 remains on a plane in the vertical direction.System also comprises controller 10 and driver 12, arranges controller 10 and driver 12 respectively, arrange driver 12 between The Cloud Terrace 8 and computing machine 11 between digital processing unit 7 and computing machine 11.
The identification process of the adaptive location iris image capturing system that the utility model provides is as follows:
Being captured under near infrared lamp throws light on of iris image is carried out.First face video camera 6 carries out scanning, detecting face in visual field.After face being detected, system locates human eye in image frame, and the center of human eye, according to about the position control The Cloud Terrace of human eye in picture and rotate up and down, is aimed in the center of iris video camera 5 by digital processing unit (DSP) 7.After the center of iris is aimed in the center of iris video camera 5, start distance-measuring equipment 2, detection human eye is to the distance of video camera front end, and camera control system, according to the distance controlling video camera zoom of human eye to video camera, ensures that iris image pixel meets the requirement of iris recognition.Because iris image now might not be iris image clearly, therefore, camera control unit needs to control video camera sequential focusing, all import video flowing into DSP7, video flowing, under the detection of algorithm, finds standard compliant iris image clearly, and carries out subsequent treatment.
The adaptive location iris image capturing system that the utility model provides adopts autozoom technology and perceived distance technology initiatively to find the eyes of people, then is amplified by human eye iris region interested, and shooting meets the iris image of criterion of identification.
The embodiment of the above is better embodiment of the present utility model; not limit concrete practical range of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence change that all shapes according to the utility model, structure are done is all in protection domain of the present utility model.
