Description
Technical field
The utility model relates to technical field of biometric identification, and in particular to a kind of two axle The Cloud Terraces iris face acquisition device.
Background technique
Presented iris face acquisition device usually has fixed setting angle, and acquisition range is relatively narrow, it is desirable that user is actively
Into the acquisition range of equipment, cooperating equipment is acquired, and can not automate the different heights for adapting to user and position；There are also one
Class iris face acquisition device can manually adjust the pitch angle of image capture module, and such equipment is adapted to more use
Family height, but need to manually adjust, operation is cumbersome, and only has pitching function, can not adapt to laterally upper larger range of
User location；Another kind of iris face acquisition device can control motor and automatically adjust image capture module according to face height
Pitch angle, it is convenient to adapt to not have to user's height, but only there is pitching function, laterally upper larger range of use can not be adapted to
Family position.
Utility model content
In order to solve the above-mentioned technical problem, the utility model proposes a kind of two axle The Cloud Terraces iris face acquisition devices.
The two axle The Cloud Terraces iris face acquisition device includes image capture module, X-axis motor, y-axis motor and motor control
Molding block, the motor control module are electrically connected with X-axis motor, y-axis motor respectively.
The improvement of the utility model two axle The Cloud Terraces iris face acquisition device is that the X-axis motor, y-axis motor are
Stepper motor.
The utility model two axle The Cloud Terraces iris face acquisition device further improvement lies in that, the X-axis motor, Y-axis electricity
Machine is servo motor.
The utility model two axle The Cloud Terraces iris face acquisition device further improvement lies in that, described image acquisition module packet
Include the first a visible image capturing head of an infrared photography and one group of infrared lamp.
The utility model two axle The Cloud Terraces iris face acquisition device further improvement lies in that, the infrared camera and can
Light-exposed camera is automatic focusing camera head.
The utility model two axle The Cloud Terraces iris face acquisition device further improvement lies in that, the visible image capturing head
Angular field of view is greater than infrared camera.
The utility model two axle The Cloud Terraces iris face acquisition device, after triggering iris face registration or identification, if bigger
There is face in the colour imagery shot picture of angular field of view, image capture module pair can be controlled by X-axis motor, y-axis motor
Quasi- face；If not occurring face within the scope of colour imagery shot picture, image capture module is controlled by X-axis motor, y-axis motor
Camera angle is traversed, until occurring face in picture, image capture module is then controlled and is directed at face, the utility model can be with
Automatically different user's height and lateral user location are adapted to, iris recognition precision and ease for use are improved.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model two axle The Cloud Terraces iris face acquisition device.

Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
As shown in Figure 1, the two axle The Cloud Terraces iris face acquisition device includes image capture module 11, X-axis motor 12, Y
Motor control module inside spindle motor 13 and crust of the device, the motor control module respectively with X-axis motor 12, y-axis motor
It is electrically connected.The X-axis motor is responsible for controlling image capture module horizontal rotation, and the y-axis motor is responsible for control image and is adopted
Collect module pitch rotation.
Described image acquisition module includes 111 1 visible image capturing heads 112 of an infrared camera and one group of infrared lamp
113, it is one group that infrared lamp 113 described in preferred the present embodiment, which shares three, and the infrared camera 111 can be used to acquire
Iris image, it is seen that light video camera head 112 can be used to acquire facial image.
As shown in Fig. 2, two axle The Cloud Terraces iris face acquisition device described in the utility model is adopted by image capture module 11
Collect iris image and facial image, and by image transmitting to image processing apparatus 21, described image processing unit 21 is according to visible
Face location in picture captured by light video camera head 112 is calculated Face detection to picture center X-axis motor 12 and y-axis motor
13 respective rotation amounts send control instruction to motor control module 22, and obtain motor status by motor control module 22
Parameter, motor control module 22 control X-axis motor 12 and Y after receiving the rotation amount instruction of the transmission of image processing apparatus 21
Spindle motor 13 carries out the rotation of corresponding rotation amount.Thus by the camera face face of image capture module 11.At described image
Reason device 21 is data operation and storage platform, can be handled using portable mobile host or PC platform or high-performance MCU
Plate etc.；It is responsible for receiving user instructions, carries out image comparison, the storage of output motor control instruction and iris, face information.It is described
Motor control module 22 is responsible for driving X-axis motor 12, and y-axis motor 13 rotates respective angles, and feedback motor status parameter arrives
Image processing apparatus 21, the motor status parameter include stall, rotate forward angle feed-back, reverse angle feedback, initial bit feedback
Deng.
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.
