Abstract
The camera automatic adjusting method based on face recognition technology that the invention discloses a kind of, adjust automatically camera is realized in conjunction with human body proximity sensor, electric motor, camera and face recognition technology, camera adjustment is realized automatically by software, reduce operation and the learning cost of user, retain adjustment switch simultaneously, meets different usage scenarios.
Description
Technical field
The camera automatic adjusting method based on face recognition technology that the present invention relates to a kind of, is related to that human body is close, face
Identification technology, cooperates camera, and application product includes bank self-aid apparatus etc..
Background technique
It is retained in self-service device in use, generally requiring acquisition user image, but the shooting direction of camera is toward in the past
It is fixed, the user to height not in coverage be not it is very friendly, present invention mainly solves the problem of be: automation adjustment
The shooting direction of camera meets the shooting demand of deviation before and after height difference, standing place.
Present self-service device is higher and higher to self-help requirement, and many functions make every effort to realize by shirtsleeve operation, to the greatest extent
Amount reduces the intervention of user.
The necessary means of user's field image are left and taken in video recording of taking pictures as one, and camera must can not on self-service device
It is few, need to adjust the shooting direction of camera in user's operation, to meet reliability, the validity of image.
Current portions self-service device is adjusted by the way of manually adjusting camera and rotating upwardly and downwardly, and there are also equipment component peaces
Electric motor is filled, by user operable switch come motorized adjustment.
By the way of manually adjusting and taking the photograph, release handle needs to be arranged near camera, user inappropriate for height
For, operation is a problem.
By the way of motorized adjustment, user needs the position of the switch of motorized adjustment clear first, and there are learning costs.
Both modes require user according to height, erect-position to adjust camera, if camera needs after mobile erect-position
It readjusts, and user's arm length may not have the inappropriate problem of adjustment in the opereating specification of design, if needed
The second people is wanted to assist the essential meaning for then losing self-service device.
Summary of the invention
For the above technical problems, the purpose of the present invention is: propose a kind of taking the photograph based on face recognition technology
As head automatic adjusting method, the automatic adjustment for realizing camera reduces user's to meet the shooting demand of people of different heights
Operation and learning cost, more meet the essence of self-service device.
The technical solution of the invention is as follows is achieved: a kind of camera adjust automatically based on face recognition technology
Method includes the following steps: step 1, according to instrument size and type, pacifies in the position that can accurately collect user's approach signal
Fill human body proximity sensor；Step 2, height value is taken in the height ratio of body according to human body average height and face, in equipment
At first about half meter, the intersection point of camera shooting direction and height value is taken, takes this camera direction for default stop place；Step 3,
It is resident on backstage by software, the signal of human body proximity sensor is acquired, when receiving human body close signal, camera starting
And start to identify face；Step 4, it identifies face, according to the moving direction of face, is clapped by electric motor adjust automatically camera
Direction is taken the photograph, to guarantee face in the reasonable shooting angle of camera；It is unidentified to arrive face, then it does not adjust；Step 5, work as application
When requirements of process shoots user picture, camera shows shooting window；Step 6, there are deviations, face for user standing place or so
When not placed in the middle, user is reminded to move by way of text/voice；Step 7, human body close signal is not detected or fails
Face is recognized, then by adjusting electric motor, rotates upwardly and downwardly automatically scanning front region, is automatically stopped when recognizing face；
Step 8, it when human body proximity sensor signal becomes nobody, or can not detect face, then stop motor rotation, and carry out correlation
Prompt.
Preferably, in outside, user adjusts camera side by regulating switch for the regulating switch setting of the electric motor
To.
Preferably, in the electric motor rotation process, it not will do it shooting operation, can be clapped after angle stabilization
It takes the photograph.
Preferably, the camera is the camera for supporting automatic face focusing.
Preferably, the human body proximity sensor is mounted on hits exactly in front of equipment 0.5 meter on panel below operation display
Position.
Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages:
A kind of camera automatic adjusting method based on face recognition technology of the invention, in conjunction with human body proximity sensor,
Electric motor, camera and face recognition technology realize adjust automatically camera, and camera adjustment is realized automatically by software, reduce
The operation of user and learning cost, while retaining adjustment switch, meet different usage scenarios.
Specific embodiment
The present invention addressed below.
A kind of camera automatic adjusting method based on face recognition technology of the present invention, including walk as follows
It is rapid: step 1, according to instrument size and type, man body approaching sensing to be installed in the position that can accurately collect user's approach signal
Device；Step 2, height value is taken in the height ratio of body according to human body average height and face, before equipment at about half meter, takes and take the photograph
As the intersection point of head shooting direction and height value, take this camera direction for default stop place；Step 3, by software on backstage
It is resident, the signal of human body proximity sensor is acquired, when receiving human body close signal, camera starts and starts to identify people
Face；Step 4, face is identified, according to the moving direction of face, by electric motor adjust automatically camera shooting direction, to protect
Reasonable shooting angle of witness's face in camera；It is unidentified to arrive face, then it does not adjust；Step 5, when application flow needs to shoot
When user picture, camera shows shooting window；Step 6, when user standing place or so is not placed in the middle there are deviation, face, lead to
The mode for crossing text/voice reminds user to move；Step 7, human body close signal is not detected or fails to recognize face,
Then by adjusting electric motor, automatically scanning front region is rotated upwardly and downwardly, is automatically stopped when recognizing face；Step 8, work as human body
Proximity sensor signal becomes nobody, or can not detect face, then stops motor rotation, and carry out related prompt.
In outside, user adjusts camera direction by regulating switch for the regulating switch setting of the electric motor.
In the electric motor rotation process, shooting operation not will do it, can be shot after angle stabilization.
The camera is the camera for supporting automatic face focusing.
The human body proximity sensor, which is mounted below the operation display, hits exactly in front of equipment 0.5 meter of position on panel.
A kind of camera automatic adjusting method based on face recognition technology of the invention, in conjunction with human body proximity sensor,
Electric motor, camera and face recognition technology realize adjust automatically camera, and camera adjustment is realized automatically by software, reduce
The operation of user and learning cost, while retaining adjustment switch, meet different usage scenarios.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand the contents of the present invention and be implemented, and it is not intended to limit the scope of the present invention, it is all according to the present invention
