Sign is described as follows among Fig. 2:
1-holder;
2-turning axle (rotary middle spindle is the x axle);
3-movable turning axle (rotary middle spindle is the y axle);
4-folding shaft (central shaft is the y axle, by folding control collector distance users distance);
5-left rotation and right rotation axle (central shaft is the z axle);
6-upper-lower rotating shaft (central shaft is the y axle);
7-face is as collector (band camera).
The concrete workflow of present embodiment is as follows:
A) when the user occurs, controller detects the user automatically;
B) picture that obtains according to the camera in the image surface collector 7 of controller, control rotating shaft 2 axle centered by the x axle, 360 degree rotations in the y-z plane make image surface collector 7 with a suitable theta alignment user face;
C) picture that obtains according to camera of controller, control left rotation and right rotation axle 5 is a central shaft with the z axle, 180 degree rotations in the x-y RHP; Simultaneously by folding shaft 4 and movable turning axle 3, improve or reduction face as collector 7 level heights, make face as collector 7 basic with face image height degree on same level, the face picture that collects in picture be basically about between two parties;
D) picture that obtains according to camera of controller, control upper-lower rotating shaft 6 axle centered by the y axle, 180 degree rotations in the x-z RHP, further accurate consumer positioning face;
E) controller is by folding shaft 4 and moving rotary axle 3, image surface collector 7 moved on in face of the user, so that image surface size of imaging in camera is moderate;
F) face begins to carry out the identification of face picture as recognizer, and display result.
Carrying out face when locating, adopting following method as recognizer:
Each rotating shaft control principle of controller all adopts motor rotation control.Take flow process d) in upper-lower rotating shaft 6 be example, suppose that control upper-lower rotating shaft 6 begins to turn clockwise at an angle, this controller is at first by the camera collection picture, calculate the similarity of picture and image surface template, find a local maximum of similarity value according to the value that calculates, make controller be stopped at the angle of corresponding maximum.Concrete situation may be: the support arm of upper-lower rotating shaft 6 controls is to spend the angle as initial angle with fixed head near 0, and 5 degree are changing value, turn clockwise.Along with the rotation of axle, the picture that the image surface collector obtains and the similarity of image surface template will increase gradually, and to a certain angle, such as 60 degree, this similar value can diminish, so the angle of upper-lower rotating shaft 6 and fixed head just is parked in 55 degree.
Flow process c) method and flow process d that adopt in) the different of two aspects are arranged: template be not only face as template, also comprise people's figure template; The method of seeking not only relies on the rotation change of an angle.
Can adopt earlier and highly regulate up and down, left rotation and right rotation highly is finely tuned up and down more again, about the process of finely tuning find the process of proper height and proper angle.Concrete situation may be: moving rotary axle 3 is from some angles (such as spending with 2 one-tenth on rotating shaft-90), be rotated counterclockwise take 5 degree as step-length, gather simultaneously the human body picture, according to the picture that collects, calculate the similarity of the template of itself and face+figure, when a certain angle, this similarity value reduces, and then moving rotary axle 3 is stopped at last angle; Left-right rotary rotating shaft 5 is started working, and similarly, this axle also is to begin rotation from a certain angle, is stopped at a certain angle so that the image surface of obtaining and image surface template have maximum similar value.This process also can repeat once to finely tune operation automatically.
Embodiment two:
Comprise electric platform in the present embodiment in the position adjusting mechanism, motor in the electric platform is connected with controller, controller is identified according to the image of image surface collector collection, the motor operation in the control electric platform, thus make the automatic adjusting range of position adjusting mechanism as the position of collector.
Electric platform is prior art, general is used for setting up monitor or detector, and can be divided into according to its rotating characteristics can only left rotation and right rotation or up and down rotary head and the all-directional tripod head that can left rotation and right rotation can rotate up and down again.Adopt electric platform can replace left rotation and right rotation mechanism and rotating mechanism up and down among the embodiment one.For carrying out height and far and near position adjustments, also can comprise front-back position regulating mechanism or height adjustment mechanism in the position adjusting mechanism, electric platform is fixed on front-back position regulating mechanism or the height adjustment mechanism, front-back position regulating mechanism or height adjustment mechanism pass through motor-driven, motor is connected with controller, controller compares according to the image surface and the human body figure template that collect, the running of control motor, thus carry out front and back position or upper-lower position adjusting.
The utility model increases controller at existing image surface recognition device, and this controller can move on to user moderate position in front with the image surface collector by functions such as rotation, displacements, has the 6 degree frees degree.Controller can arrange separately, also can be arranged in the main frame of existing image surface recognition device.
The function that the utility model makes the image surface collector have 360 degree integral-rotations, up and down rotations, left rotation and right rotation, move forward and backward can certainly only be finished wherein one or more function.The image surface collector also can adopt the adjustable focal length camera, and the adjustable focal length camera is connected with controller, carries out focus adjustment by controller control, so just can not need the front and back position adjusting device.
The utility model has reduced the requirement degree that the user is cooperated, and further strengthens the function of image surface recognition device aspect contactless.Those skilled in the art do not break away from essence of the present invention and spirit, can there be the various deformation scheme to realize the present invention, the above only is the better feasible embodiment of the present invention, be not so limit to interest field of the present invention, the equivalence that all utilizations specification of the present invention and accompanying drawing content are done changes, and all is contained within the interest field of the present invention.
