In embodiments of the present invention, user can use mobile terminal as scanning device, to shooting document, certificate, sea
The picture that report etc. is formed is acquired and adjusted, while being optimized to the border of picture, removes the background area of picture boundary
Domain, can also recognize text information in picture, be converted into editable document format.
Based on this, the embodiment of the present invention provides a kind of image processing method, refer to Fig. 1, and it is institute of the embodiment of the present invention
The schematic flow sheet of a kind of image processing method provided, as illustrated, this method comprises the following steps：
Step S101, gathers the first picture region in pending picture.
Further, step S101 is refined as follows：
According to the brightness value of each pixel in processing picture, each side of the first picture region is determined by preset strategy
Edge；
According to each picture region of edge collecting first；
Wherein, first picture region is quadrangle.
First picture region described herein is the region of user's needs collection in pending picture, the first picture region
Image parameters information can have part and be clearly distinguishable from other regions (other in i.e. pending picture outside the first picture region
Region), that is to say, that the first picture region is with obvious boundary.For example, document (such as PPT documents) institute is being shot
During the picture of formation, due to the difference of focusing and brightness of finding a view in itself, document areas part luma is higher in view area, and
Background area portion brightness outside document areas is relatively low, so when being ultimately imaged, document area pixel point is bright in picture
Angle value and the brightness value gap of document areas perimeter pixel can be than larger, by each pixel pixel value in picture
Can have the brightness value inside and outside obvious boundary, boundary if expression, in picture can have obvious drop.
The calculating and processing of data for convenience in the embodiment of the present invention, carries out boundary determination in a linear fashion, in inspection
Measure and directly extend to form corresponding boundary straight line to two ends after the boundary line segment for meeting preset length, if document content is rectangle
, though when shooting angle there is the document content region on difference, final photo to be also quadrangle, so finally can determine whether
Go out four boundary straight lines, the region that four boundaries are surrounded is the first picture region scope, determines the model of the first picture region
The first picture region is drawn after being cut or split after enclosing.
The above-mentioned line segment that first fixes limit, is carrying out the mode of line segment extension generation boundary straight line, because need to only determine part
Boundary line segment, it is possible to largely reduce the operand of the processing assembly of mobile terminal, reduce picture processing mistake
Journey while picture processing speed can also be lifted, allows user to obtain more preferable usage experience the occupancy of process resource.
Step S102, designated shape is adjusted to by first picture region, generates the first picture.
Further, step S102 is refined as follows：
Four apex coordinates of first picture region are obtained, the corresponding rectangle region of first picture region is calculated
The length-width ratio in domain；
According to four apex coordinates and the length-width ratio of the rectangular area of first picture region, described is calculated
One picture region is converted to the transformation equation of rectangular area；
First picture region is adjusted to rectangular area using the transformation equation, the first picture is generated.
It should be noted that being influenceed by shooting angle, the first picture region is usual and non-rectangle, and smart machine can be by four
Side shape region is adjusted to behind rectangular area, generates corresponding picture.
Specifically, in embodiments of the present invention, the origin of coordinates can be then based on first by preset coordinate origin
Coordinate system is set up in picture region, the coordinate on first four summits of picture region can be thus obtained respectively, is thrown using perspective
Shadow equation calculates four apex coordinates of the corresponding rectangular area of the quadrilateral area, is sat according to the four of rectangular area summits
Mark calculates the length-width ratio of the rectangular area, then calculates the conversion side that first picture region is converted to rectangular area
Journey, the transformation equation said here can be homography conversion, and corresponding rectangle picture can be generated after conversion.
Step S103, recognizes the text information in first picture, by the pictorial information and text in first picture
Word information saves as the document of specified format.
It should be noted that OCR (Optical Character Recognition, optical character identification) skill can be passed through
Art recognizes the text information in the first picture.OCR technique refers to the character information of mobile terminal check picture, by detection it is dark,
Bright pattern determines its shape, and shape then is translated into computword with character identifying method.
Its text information and pictorial information after text information, are saved as specified lattice by the embodiment of the present invention in identification picture
The document of formula, to facilitate user to enter edlin to document content according to demand in use.Wherein, specified format can be doc
Form, pdf forms, txt forms, PPT forms etc..
As preferred, the pictorial information and text information in the first picture are saved as PPT forms by the embodiment of the present invention
Document, the documents of PowerPoint PPT forms can compatible pictorial information and text information simultaneously, if first in pending picture
The corresponding PowerPoint PPT document contents of picture region, are still saved as the document of PowerPoint PPT forms after treatment,
Document content obtains higher reduction degree, so as to close to the original presentation manuscript PPT documents of displaying, facilitate user to be read
Read, furthermore, picture letter and text information in the document of PowerPoint PPT forms can carry out further according to the demand of user
Editor.
Further, the method for the embodiment of the present invention also includes：
In response to the operational order for the text information, the text information is modified.
It should be noted that in actual application, user sometimes needs increase annotation, note reading or content
On increase and decrease, user can be to operational order of the mobile terminal input pin to the text information, and mobile terminal can be in response to
The operational order, and correspondence modification is carried out to text information according to the operational order.In addition, if the embodiment of the present invention is by first
Pictorial information and text information in picture save as the document of PowerPoint PPT forms, for PowerPoint PPT format files
All edit operations, such as increasing effect animation, replacement background picture, increase video/audio etc. can refer in the operation of user
Under order, accordingly edited.
The image processing method of the embodiment of the present invention, after the first picture region in gathering pending picture, is adjusted
It is whole to recognize text information in the first picture to generate the first picture, then for designated shape, and by the picture in the first picture
Information and text information save as the document of specified format.Compared with prior art, technical solution of the present invention being capable of automatic data collection
Respective regions in picture are simultaneously adjusted, and without collection manually and adjustment, improve the degree of accuracy and automation of picture processing
Degree, it is higher to the reduction degree of processing region image content, while the text information in picture can also be identified, and will
