Description
Technical field
The present invention relates to a kind of portrait collecting device and method, more specifically, the present invention relates to a kind of portrait intelligent acquisition Apparatus and method for.
Background technology
Present alert with MIS in, the portrait acquisition function is indispensable module.Gather the module of personnel's standard photographs as the ancillary staff, present function is still very original.After common way was operator's manual adjustment camera mount, running program was taken pictures, and manually pulled the people image position of virtual view-finder to the photo, location then, could obtain the portrait photo, also synthesize the electronics chest card.The omnidistance human eye that relies on carries out the judgement of effects such as photographic quality, portrait scope.
Existing portrait acquisition module relies on the support of staff wage adjustment joint camera fully, and when not gathering the portrait photo that obvious different heights are arranged, operating personnel will remove the height of manual adjustment support.
When taking pictures, need to require the personnel that gathered to keep motionless as taking a picture equally, control is taken pictures then.Portrait carries out manual positioning in the photo for taking again.The judgement of portrait quality also all is to rely on directly perceived the observation to judge.Mode of operation is very original, and efficient is low, and not reference, of low quality of the photo that obtains, and user friendly is also very poor.
Summary of the invention
The purpose of this invention is to provide a kind of software and hardware integrated solution that can carry out that equipment is controlled automatically, portrait is analyzed automatically, gather and cut apart.It can analyze the live video stream from camera automatically, carries out the automatic or manual control that support goes up and down, and realizes that the automatic or manual of portrait is located, cut apart, and accurately synthesizes the electronics chest card, thereby significantly improves the efficient and the quality of portrait collecting work.
First aspect of the present invention provides a kind of portrait intelligent acquisition equipment, comprising: portrait collecting device, single-chip microcomputer, camera mount, camera drive and people's face detection module.When starting the portrait capture program; The portrait collecting device produces reaction to CLIENT PROGRAM; By the camera drive controlling, will give special people's face detection module from each frame image data of the live video stream of camera; People's face detection module adopts the disclosed people's face detection sorter of Intel (cascade) to carry out people's face detection computations, to obtain the coordinate range Rect1 of people's face on the photo.(the head portrait photo size is 358 * 441 pixels according to general provision according to the universal law of the position of people's face and whole head portrait relation then; People's face is the position on the upper side of the centre in the head portrait scope usually); Carry out the compute location of head portrait scope; Obtain the coordinate range Rect2 of head portrait, realize the head portrait automatic positioning function.As long as the head portrait data cutout among the Rect2 is come out, just realized cutting apart automatically.Program can all draw Rect1, the Rect2 of each the frame picture in the video flowing, and on the interface, forms two along with the real-time animation frame of being gathered people's change.
Operating personnel are according to live video stream, camera parameters such as brightness, contrast are set after, begin to take.Program is taken 10 photos continuously according to the Rect2 that calculated at that time, accomplishes to cut apart automatically.Program portrait photo's computed image that intercepting is gone out then, according to photo parameters such as illumination, contrast, aberration, the computed image quality, and arrange and show.The operator can see the massfraction of any photo, also can click the feature of checking photo and show, and on the feature picture, drag the corresponding frame of Rect2, realizes the manual adjustment location.Can confirm then the picture data of selecting as final data.
Portrait intelligent acquisition equipment of the present invention has added monolithic processor controlled lifting motor to camera mount, and single-chip microcomputer can receive and handle the steering order from main frame; Program can judge that position of camera is a height or low according to people's face, portrait result of calculation in addition, sends instruction to single-chip microcomputer in view of the above, and the control motor rises or descends, thereby the height of realizing camera on the camera support is regulated.Operating personnel also can pull image up and down on the program picture, to reach the purpose of manual adjustments support height.
Second aspect of the present invention provides a kind of portrait intelligent acquisition method, comprises the steps:
(1) makes the com automation service routine, can start from any client of this type of function of needs;
(2) SDK of use camera is provided with parameter.Use the call back function register method of camera, register self-defining call back function, be used for handling each frame (frame) view data from the live video stream of camera.
(3) call back function one frame image data that will transmit is given special graphical analysis procedure, adopts the disclosed people's face of Intel to detect sorter (cascade) and carries out people's face detection computations, to obtain the coordinate range Rect1 of people's face on the photo.Then according to the universal law of the position of people's face and whole head portrait relation (the head portrait photo size is 358 * 441 pixels, the people's face position on the upper side of the centre in the head portrait scope usually according to general provision); Carry out the compute location of head portrait scope; Obtain the coordinate range Rect2 of head portrait, realize the head portrait automatic positioning function.As long as the head portrait data cutout among the Rect2 is come out, just realized cutting apart automatically.Through above result of calculation, the auxiliary pattern that on the image buffers data, draws is shown on the program interface, accomplish be shown to the user in real time, preview effect accurately, promptly two along with the real-time animation frames of being gathered people's change.
(4) operating personnel are according to live video stream, camera parameters such as brightness, contrast are set after, begin to take.Program is taken 10 photos continuously according to the Rect2 that calculated at that time, accomplishes to cut apart automatically.Program portrait photo's computed image that intercepting is gone out then, according to photo parameters such as illumination, contrast, aberration, the computed image quality, and arrange and show.The operator can see the massfraction of any photo, also can click the feature of checking photo and show, and on the feature picture, drag the corresponding frame of Rect2, realizes the manual adjustment location.Can confirm then the picture data of selecting behind the Base64 coding,, to return to the customer as final data.The filename that also can provide according to the customer in addition is saved in local file.
Key problem in technology point of the present invention is:
1, software program is all given special people's face detection algorithm with each frame data of video flowing, according to the universal relation of testing result and people's face and people image position, calculates the portrait scope.
2, added monolithic processor controlled lifting motor to support unit, single-chip microcomputer can receive and handle the steering order from main frame.
3, on program interface, definition and judge the up-down camera, pull people's face sensing range and pull the different operating of portrait capture frame scope issues steering order in view of the above or obtains picture region.
Beneficial effect of the present invention mainly contains the following aspects:
1, can realize the automatic or semi-automatic adjusting of camera heights, improve the camera location efficiency;
2, detect people's face, portrait automatically, and on program interface, provide demonstration directly perceived, obviously improve operator's work quality;
3, a plurality of portrait photos that list continuous shooting are as candidate item, and provide the Mass Calculation result respectively, make to select the portrait photo that science is more arranged.
