Description
Technical field
The utility model relates to technical field of biometric identification, and in particular to a kind of iris capturing equipment with distance measurement feedback.
Background technique
Iris capturing equipment mostly uses the iris camera of fixed focal distance at present, to the distance between user and equipment
It is restricted, can be shorter with iris recognition section, have the shortcomings that focusing speed is slow using the iris capturing equipment of auto-focusing, uses
Family experience is poor.
Utility model content
In order to solve the above-mentioned technical problem, the iris capturing equipment with distance measurement feedback that the utility model proposes a kind of.
The iris capturing equipment with distance measurement feedback includes pedestal, image capture module, and there are two branch for the pedestal tool
Column, image capture module in the pillar of pedestal side by being equipped between rotatable two pillars for being fixed on pedestal of shaft
One motor, image capture module is interior to be equipped with iris camera, face camera, infrared lamp.
The improvement of iris capturing equipment of the utility model with distance measurement feedback is that the motor is servo motor, can be with
The angle that control image capture module is rotated up and down.
Iris capturing equipment of the utility model with distance measurement feedback further improvement lies in that, the motor be stepping electricity
Machine can control the angle that image capture module is rotated up and down.
Iris capturing equipment of the utility model with distance measurement feedback further improvement lies in that, described image acquisition module is also
Equipped with range sensor.
Iris capturing equipment of the utility model with distance measurement feedback further improvement lies in that, the iris camera can be with
Auto-focusing.
Iris capturing equipment of the utility model with distance measurement feedback further improvement lies in that, the face camera is shared
Two, one is infrared face camera, and one is colored human face camera, the transversely arranged composition face camera shooting of two cameras
Head group.
Iris capturing equipment of the utility model with distance measurement feedback further improvement lies in that, the face camera group,
Iris camera and range sensor fall down to be arranged successively from above, and the distance between face camera group and iris camera are less than
6cm。
Iris capturing equipment of the utility model with distance measurement feedback further improvement lies in that, the shaft is hollow circle
Cylindricality state, the connecting line of image capture module is by shaft intermediate void cabling, by pedestal column cabling channel and pedestal cabling
Slot is stretched out behind by pedestal.
Iris capturing equipment of the utility model with distance measurement feedback, instructs rainbow by the range information that range sensor measures
Film camera carries out auto-focusing, to promote focusing speed, the distance between face camera group and iris camera are less than
Face camera group and iris camera module are arranged close to by 6cm, it is possible to reduce parallax between the two, face camera
Focal length be less than iris camera, by captured by identification face camera in picture face position, motor can be instructed
The pitch angle for controlling image capture module, adapts to different user's height automatically, iris camera is made to photograph clearly iris
Image.
Detailed description of the invention
Fig. 1 is iris capturing equipment schematic diagram of the utility model with distance measurement feedback.
Fig. 2 is image capture module module position schematic diagram.
Fig. 3 is pillar hollow axle schematic diagram.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
As shown in Figure 1, Figure 2 and Figure 3, the iris capturing equipment with distance measurement feedback of the utility model includes pedestal 11, figure
As acquisition module 12, for the pedestal tool there are two pillar 111, image capture module 12 passes through the fixation that shaft 31 can be rotated up and down
Between two pillars 111 of pedestal, it is preferred that be equipped with a stepper motor, stepping electricity in the present embodiment in the pedestal column of right side
Machine can control the rotation angle of image capture module 12, and infrared face camera 211, colour are equipped in image capture module 12
Face camera 212, iris camera 22, infrared lamp 23, range sensor 24, arrangement mode is as shown in Fig. 2, wherein infrared lamp
23 and range sensor 24 completely in the inside of 12 shell of image capture module；Shaft 31 is hollow cylindrical conformation, and image is adopted
Collect the connecting line of module by shaft intermediate void cabling, by pedestal column cabling channel and pedestal cabling channel, behind by pedestal
It stretches out.
Wherein range sensor can measure the range information of user and equipment room, and iris camera 22 is instructed to carry out automatically
The focal length of focusing, two face cameras is less than iris camera 22, passes through people in picture captured by locating human face's camera
The position of face, can instruct the pitch angle of step motor control image capture module 12, adapt to different user's height automatically,
Iris camera 22 is set to photograph clearly iris image.
The distance between face camera group and iris camera 22 are less than 6cm, face camera group and iris camera
Parallax should be reduced as close as possible to setting, since camera lens is mostly cylindrical conformation, in the present embodiment, face camera group is taken the photograph with iris
As first 22 distance refers to the line in two face camera centers of circle at a distance from 22 center of circle of iris camera.
Combine accompanying drawings and embodiments that the utility model is described in detail above, those skilled in the art can
Many variations example is made to the utility model according to the above description.Thus, certain details in embodiment should not be constituted to this reality
With novel restriction, the utility model will be using the range that the appended claims define as the protection scope of the utility model.
