On quasi- image.In one embodiment, the standard picture is facial image, and the sphere of action is an elliptic region, is used
Elliptical major and minor axis and rotation angle can be set in family, the ellipse area can be shown on default location on facial image
Domain, user can change the position of sphere of action by dragging elliptical central point at this time, for example drag from the region of nose
To the region of eyes, then corresponding deformation process will be carried out to eye image, sphere of action and deformation as illustrated in fig. 2 c
Effect
Sphere of action is shown on standard picture, also facilitates user to check the expected effects of deformation, and according to the effect tune
The parameter of whole items deformation.In one embodiment, the relative position of the sphere of action is determined by characteristic point, in Fig. 2 b
Shown in human face characteristic point.The characteristic point of image, which refers in image, to be had distinct characteristic and can effectively reflect image substantive characteristics
And it can be identified for that the point of target object in image.If target object is face, just need to obtain face key point, if
As soon as target image is a house, then needing to obtain the key point in house.Illustrate the acquisition methods of key point by taking face as an example,
Facial contour mainly includes 5 eyebrow, eyes, nose, mouth and cheek parts, will also include pupil and nostril sometimes, generally
For realize facial contour more completely described, need the number of key point at 60 or so, if the only basic knot of description
Structure does not need that each position details is described in detail, or does not need description cheek, then can accordingly reduce key point number,
If necessary to describe pupil, nostril or the five features for needing more details, then it can increase the number of key point.On the image
The extraction of face key point is carried out, is equivalent to the corresponding position coordinate for finding each facial contour key point in facial image, i.e.,
Crucial point location, this process need to carry out based on the corresponding feature of key point, can clearly identify key point obtaining
It after characteristics of image, scans for comparing in the picture according to this feature, is accurately positioned the position of key point on the image.Due to
Characteristic point only occupies very small area (usually only several sizes to tens pixels) in the picture, and characteristic point is corresponding
Feature on the image occupied region be generally also it is very limited and local, there are two types of feature extraction modes at present:
(1) the one-dimensional range image feature extraction vertical along profile；(2) the two dimensional range image characteristics extraction of characteristic point Square Neighborhood.
There are many kinds of implementation methods for above two mode, such as ASM and AAM class method, statistics energy function class method, regression analysis side
Method, deep learning method, classifier methods, batch extracting method etc..Key point used in above-mentioned various implementation methods
Number, accuracy and speed are different, suitable for different application scenarios.
Since the deformation for being deflected into the collected image of imaging sensor on standard picture needs a mapping relations,
Different according to the mode of mapping, the mode of deformation can be divided into fixed deformation and tracking deformation, in one embodiment using solid
Setting becomes, and this deformation is fairly simple, it is only necessary to the absolute position of entire deformation range in the image sensor is set,
The pixel that implementation can be the Image Acquisition window by display device and imaging sensor corresponds, and judges deformation model
Position in a display device is enclosed, the corresponding position of imaging sensor acquisition window acquired image is carried out later corresponding
The advantages of deformation process, this deformation process mode be it is simple to operation in another embodiment, generate strain image when, first
The characteristic point of standard picture in obtaining step S203 determines the sphere of action in standard picture by the characteristic point
Position；From by identifying the first image corresponding with standard picture in imaging sensor institute acquired image；It will be in standard drawing
Identified position is mapped in the first image as in；Deformation process is done to the first image, generates strain image.The deformation mode
In, determine the relative position of deformation range in the target image, no matter how target image moves variation, and the deformation range is total
On the relative position, achieve the purpose that track deformation.In a typical application, the standard picture has been referring to work
Standard faces image, the standard picture pass through triangulation, there is 106 characteristic points, when sphere of action is arranged, utilize shape
The relative position for becoming range and characteristic point determines relative position of the sphere of action in facial image, to the collected people of camera
Face image does same triangulation, and later when mobile or rotation occurs for the face in camera, the deformation can be always
It is fixed on the relative position on face, to achieve the effect that track deformation.
For the tracking deformation mode in above-described embodiment, standard picture and acquired image use same set of feature
The number of point, characteristic point is identical, such as in standard picture No. 6 characteristic point and imaging sensor acquired image No. 6
Characteristic point, the position on standard picture and the position in acquired image are identical.Due to the center of sphere of action
In general point is always located in some triangle interior, therefore can determine sphere of action central point using 3 characteristic points
Position, as shown in figure 3, tri- points of A, B, C are the characteristic point in image, P is the center position of sphere of action, and D point is line segment
The extended line of AP and the intersection point of line segment BC, wherein the coordinate of A point is (Xa,Ya), the coordinate of B point is (Xb,Yb), the coordinate of C point is
(Xc,Yc), the coordinate of D point is (Xd,Yd), the coordinate of P point is (Xp,Yp), then available 2 linear difference coefficients Wherein BD, BC, AP and AD respectively indicate the length of line segment,
In standard picture
In, the coordinate of A, B, C, P are known value, therefore BD, BC, AP and AD can be used and calculate λ1And λ2；To image sensing

Identical characteristic point A1、B1、C1, A1、B1And C1Coordinate in the coordinate system of imaging sensor be given value, at this time use A1、B1
And C1Coordinate value and linear difference coefficient lambda1And λ2P corresponding with P point can be calculated1Coordinate system of the point in imaging sensor
In coordinate.If should be noted that A, B are identical with the number of C, A, B and C concurrent, P point is located on A point at this time, is not necessarily to
Calculate λ1And λ2Value；When the number of B and C is identical, then B, C, D concurrent, triangle is degenerated to line segment at this time, and the position of P is by λ2Certainly
It is fixed, without calculating λ1；When A and B concurrent or A and C concurrent, the case where the sequence of A, B and C can be exchanged, be converted into BC.It should
Scheme is thus to calculate P point using the relative position between linear difference coefficient record deformation central point and three characteristic points and reflect

The distalmost end of axis forward direction；When the number of A point is more than or equal to the label of 0, B point less than 0, target point is being located at sphere of action Y-axis just
To distalmost end.
Other than the position at center, it is also necessary to record the length R of sphere of action, the length can by two characteristic point E,
F and length factor S is described, specific: R=EF × S, R is given value in standard picture, and EF is characterized point E and characteristic point F
Between line segment length, it is possible thereby to calculate length factor Under the coordinate system of imaging sensor, E, F are corresponding
Characteristic point E1And F1Coordinate be given value, then length R of the sphere of action under the coordinate system of imaging sensor1Can by with
Lower formula calculates:E1F1× S, for the sphere of action of some shapes, with multiple length, such as oval tool
There are long axis and short axle, rectangle has long and width, multiple length factor S can be calculated separately for each length at this time, for remembering
Record the relative length of each length.
User can be set whether sphere of action follows the rotation of target image and rotate, if not following rotation, only
The x radial direction of sphere of action need to be kept parallel with screen width (horizontal) direction, while y radial direction is also inevitable high with screen
It is parallel to spend (vertical) direction.It is rotated when sphere of action needs to follow the rotation of target image, then it needs to be determined that effect model
The angle enclosed, the angle indicate that sphere of action needs to rotate how many angle to keep opposing stationary with the target image.Institute
State the vector that angle can be made of two characteristic points G and HDirection determine, such as sphere of action X-axis with's
Angle needs to keep a fixed value, and when the collected target image of imaging sensor rotates, the sphere of action is needed
It will be withIt is kept fixed angle, makes corresponding rotation.
The record of the parameters of the above sphere of action is to calculate relative value for reference with characteristic point, and pass in image
The actual parameter of sphere of action is calculated in the coordinate system of sensor, the disclosure is not limited the calculation of relative value, as long as
It is able to record the mode of the relative value of sphere of action parameters, is used equally for the disclosure.
