Description
Technical field
The utility model belongs to the digital electric technical field, relates to a kind of USB camera, relates in particular to a kind of twin-lens USB camera.
Background technology
Camera is divided into digital camera and simulation camera two big classes.The analog video signal that traditional simulation camera obtains image information to be needed earlier video capture device to be produced is caught card through specific video and is converted digital signal to, and then processing such as just can store.Digital camera can directly be caught image and be produced digital signal, is transferred in the computer by string, parallel port or USB interface then.The general structure of digital camera head comprises cmos image sensor, graphics processing unit, JPEG compression unit and USB device interface as shown in Figure 1.Wherein, cmos image sensor is in order to acquisition of image data, graphics processing unit is handled the view data of cmos image sensor collection, and the view data after the JPEG compression unit will be handled is compressed, and is transferred on the display unit by the USB device interface then image is shown.Compared to the simulation camera, the digital camera head tool has great advantage, as: cmos image sensor directly produces original image data; The JPEG compression of hardware supports standard; Main flow usb bus equipment interface at a high speed etc.Because the whole cost of simulation camera is higher, and the transmission speed of USB interface is higher than the speed of serial ports, parallel port far away, so current market focus mainly is the digital camera head of USB interface.
In public places of business such as Internet bar, hotels,, need the registration client identity authentication according to the public security requirement.Traditional register method is to use the identity card registration.Recently the appearance of faking along with identity card presses for a kind of new registration authentication mode, and wherein the identity identifying method based on biological informations such as people's faces begins to promote the use of.In concrete the application, generally use visible light USB camera, but, bring very big difficulty to identification owing to be subjected to the variation of the influence----surround lighting of illumination; Change the harmful effect that identification is brought in order to evade surround lighting, adopt infrared camera to improve the reliability of identification usually; But the infrared light photo is gray level image (monochrome image), and it is clear inadequately to be used for preserving when keeping on file, so all there is certain problem in such scheme.How to address the above problem is an important directions of current research.
