In this embodiment, the conversion formula in the said color conversion cell 42 is:

Y＝0.299R+0.587G+0.114B

Cb＝0.564(B-Y)

Cr＝0.713(R-Y)

Wherein R, G, B represent the red, green, blue component of said core photo respectively; Y is meant that then luminance component, Cb refer to the chroma blue component, and Cr refers to the red color component; Parameter in the said conversion formula can be provided with according to actual needs, and this embodiment only with a kind of more excellent conversion parameter for example.

Because the shooting operation of core photo is to work in the open air usually; The common digital camera that camera adopts; Weather condition is that the sun is exposed to the sun, is the cloudy day sometimes that surround lighting changes relatively greatly, causes the brightness of photo and colourity that very big variation is arranged sometimes; Thereby the rgb value of same object is changed too big under surround lighting, be not easy to correct analysis.The YCbCr space then provides a kind of method that luminance component/blue component/red component is separated; Therefore said color conversion cell 42 converts said core photo into the YCbCr spatial data; Can exempt the influence of environmental factor comparison film brightness, make the utility model processing unit go for various environment for use.

As a kind of preferred implementation, said image identification unit 43 comprises: image binaryzation unit, picture search unit and decision unit (figure does not show).

Particularly, said image identification unit 13 is calculated the formula of the mean value of Cb component:

$U=\underset{j=1}{\overset{\mathrm{Width}}{\mathrm{\Σ}}}\underset{i=1}{\overset{\mathrm{Height}}{\mathrm{\Σ}}}{\mathrm{Cb}}_{\mathrm{ij}}/(\mathrm{Width}\×\mathrm{Height})$

Wherein, Width is the width of image, and Height is the height of image, by the resolution decision of said core photo.

In this embodiment; Behind the mean value that calculates said Cb component; Said image identification unit 43 adopts following formula to judge each pixel of said core photo, carries out image segmentation, converts the Cb component image of said core photo into binary image:

${\mathrm{Image}}_{\mathrm{ij}}=\left\{\begin{array}{cc}1& \mathrm{if}{\mathrm{Cb}}_{\mathrm{ij}}\≤\stackrel{\‾}{U}-30\\ 0& \mathrm{if}{\mathrm{Cb}}_{\mathrm{ij}}>\stackrel{\‾}{U}-30\end{array}\right.$

The value of the pixel of the binary image after the Image presentation video in the above-mentioned formula is cut apart.Said picture search unit is searched in said binary image, identifies the coordinate of the casing label that is arranged on four angles of core casing.

Partition value in the above-mentioned formula

gets through a large amount of test statistics; Through a large amount of photos is carried out Processing Test, confirm that the recognition effect of this value is best.Those skilled in the art can set the partition value that is different from

according to the needs in the practical operation.But note: if we strengthen partition value, the identified region that obtains will diminish, and might not identify mark, if reduce this partition value, possibly come out background also wrong identification so, causes our recognition result to lose efficacy.

In this embodiment, after the binary conversion treatment through said image binaryzation unit, the value in four orange casing labels and the binary image of some background interference after image segmentation is 1, and the value of all the other background images is 0.

At this moment; (value is that 1 pixel is assembled the contiguous pixels piece that forms to Blob in the said picture search unit searches image; Be blackening); Adopting each pixel 8 neighbours all around in the searching image, is that 1 neighbours' each other pixel is added on and forms a set together with value, is said Blob.Travel through whole core photo, obtain all values and be 1 consecutive data block (or claiming Blob).Calculate the area of each Blob, four Blob that area is maximum are as Search Results, and remaining disturbs as a setting and gives up to fall.

Said decision unit is identified as the coordinate of four casing labels with the position of center in image of the Blob of said four areas maximum; Further, can in the demonstration forms of said core photo, show the circle marker of four fillings respectively,, be convenient to desk checking whether the core casing gets four jiaos all discern correct to show recognition effect according to the coordinate of the casing label that calculates.

If recognition result is correct, then said image identification unit 43 gets into next and opens photo identification work.Judge that whether recognition result correctly can come to realize automatically, and when identification is correct, get into next photo identification work automatically through the corresponding judgment standard is set, and sends alarm when incorrect in said image identification unit 43; Also can let and show that the position of the circle marker of four fillings judges in the demonstration forms of operating personnel according to said core photo respectively; When operating personnel judge that recognition result is incorrect; Can be through the said operational means 17 of the said processing unit of above-mentioned connection; Like mouse, keyboard or touch-screen etc.; Click the image of four jiaos casing label 12 of core casing 11 in the core photo, obtain four angular coordinates, make said image identification unit 43 get into next photo identification work by next or shortcut F6 then;

Said image identification unit 43 repeats above-mentioned to casing label identification step, discerns all the core photos under this boring numbering file, with the photo four angular coordinate that obtains to being saved in the predefined array of program.

During the said analysis picture of said image interception unit 44 interceptings,, wiped out the useless background beyond the core case, the analysis picture after obtaining handling according to the coordinate of four casing labels in above-mentioned each core photo that recognizes.

In an embodiment; Said rename unit 45 calculates the following quantity of analyzing picture of file of same boring numbering through program; Retrieve and sort with filename; Obtain the position that each analyzes picture file, combine at last, each is analyzed picture file save as the filename form of shape like " boring numbering-which case-common a few case .jpg ".

Said report generation unit 46 gathers the analysis picture that belongs to identical boring numbering according to the title of said analysis picture, adopts the PDF generation technique, generates the report of core photo.

As a kind of embodiment for example, said report generation unit 46 is quoted iTextSharp.net class libraries, working procedure; Select boring numbering corresponding file folder, read the analysis picture in each file automatically successively, insert and analyze picture; And insert the corresponding file name, and carry out the scaling of image, place 4 rows at an A4 paper; The core photo that every row is two, and add contents such as header, footer, the page number and catalogue, form a complete core photo report.

Because when generating the report of core photo; The data volume of Flame Image Process is very big; The resolution of core photo is high again, and therefore said report generation unit 46 carries out the generation of core photo report again after all casing label coordinates are confirmed correctly; Let computing machine handle automatically exactly, need not operating personnel and wait for.

Again because the pdf form is adopted in the core photo report that said report generation unit 46 generates, even the photo number is very big, still can be very smooth open and browse pdf, when having avoided employing Word text, file is excessive and cause the shortcoming that can not open.
