Said shooting module comprises camera and has the whirligig of round end that said camera links to each other with the round end of said whirligig, is used to make the camera rotation.Wherein, the anglec of rotation of said round end is the 0-360 degree.Wherein, the anglec of rotation of said round end is preferably 90 degree, be used to make camera collection to direct picture be vertical with the scene picture.
As one of preferred version of the utility model, said camera is a staggered scanning type camera.
As one of preferred version of the utility model, said camera head further can also comprise the picture conversion module; The input end of said picture conversion module links to each other with the output terminal of said camera, is used for the picture rotation back output that this camera collection is arrived.
As one of preferred version of the utility model, said picture conversion module is through software or IC chip control.
Compared to prior art, the camera head in the described a kind of face identification system of the utility model is on the basis of adopting conventional staggered scanning camera; When installing or taking; Through whirligig camera is revolved and to turn 90 degrees, the scene left and right sides that makes camera collection arrive is narrow, and is wide up and down; And pass through the picture conversion module with picture reverse rotation 90 degree, improve the visuality of picture.
The beneficial effect of the utility model is:
1. this device can improve the resolution of the people's face that collects.Owing to being revolved, interleaved camera turn 90 degrees installation; Can improve the resolution of the vertical texture of gained facial image face; The HFS of the vertical texture of face can well keep, and cross grain relative high frequency part is few, and technology such as employing deinterlace interpolation are enough to handle.
2. the scene left and right sides that collects of this device is narrow, wide up and down, and adaptable height scope is big; Narrow, the wide up and down monitoring scene that also can well adapt to the left and right sides.
3. this device adopts conventional staggered scanning camera to replace the camera of high definition, thereby has reduced the cost of face identification system.
