Step 101, collection target detection image, described target detection image comprises at least two chromatographys marks, and each chromatography mark is formed by the shower nozzle spray printing of different mass colour respectively.
Particularly, in chromatography process, such as, C (green grass or young crops), M (magenta), Y (Huang), K (black) four-colour chromatography process, when stock is successively by this four looks shower nozzle, person four look shower nozzle can mark on the same position of stock in spray printing chromatography, and usual spray printing is at the edge of stock.The target detection image that the present embodiment gathers, is the image including this four-colour chromatography mark, can gather target detection image by industrial camera lamp, and the target detection image of collection is input to computing machine carries out analyzing and processing.It will be appreciated by persons skilled in the art that four-colour chromatography process is only exemplary, double-colored chromatography, three look chromatographys etc. can also be adopted to carry out spray printing to stock.
More specifically, chromatography mark can be any one in cross curve mark, opal mark or single circle mark, also can be beyond this three kinds of chromatographys mark, any mark can demarcating spray printing position.
Step 102, determine each chromatography mark relative to standard sleeve marking note side-play amount.
Particularly, from target detection image, extract the position relationship that each chromatography mark and standard sleeve marking are remembered.Such as, cyan (C) chromatography mark is positioned at left side 0.001cm, the 0.2cm place, below of standard sleeve marking note, magenta (M) chromatography mark is positioned at the 0.06cm place, right side of standard sleeve marking note, yellow (Y) chromatography mark is positioned at the 0.013cm place, top of standard sleeve marking note, and black (K) chromatography mark is positioned at the 0.013cm place, left side etc. of standard sleeve marking note.Usual side-play amount comprises the combination of transversal displacement, vertical misalignment amount, transversal displacement and vertical misalignment amount, and that is, each chromatography mark is relative to the upper and lower, left and right position relationship of standard sleeve marking note.
Step 103, according to described side-play amount determination chromatography precision.
After determining the side-play amount of each chromatography mark relative to standard sleeve marking note, the precision of the printing quality relevant criterion determination chromatography that general administration announces can be published according to national news.Those skilled in the art are understandable that, side-play amount is less, chromatography precision is higher.
The present embodiment, the side-play amount determination chromatography precision marked by chromatography, solves in prior art, the technical matters that detection method error is larger.

Particularly, such as four-colour chromatography, gray level image will have the chromatography of four different gray scales to mark, can from chromatography Marker selection chromatography mark of these four different gray scales as reference mark.Such as, random selecting chromatography mark is remembered as standard sleeve marking.Again such as, select according to presetting algorithm.
Step 204, determine each chromatography mark relative to standard sleeve marking note side-play amount.
Particularly, such as four-colour chromatography, after determining standard sleeve marking note, determines its excess-three side-play amount that chromatography mark is remembered with this standard sleeve marking.
Step 205, according to described side-play amount determination chromatography precision.
Particularly, step 205 is identical with step 103, repeats no more herein.
Step 206, the gray-scale value marked according to each chromatography, determine the shower nozzle that each chromatography mark is corresponding.
Particularly, according to the corresponding relation of gray-scale value and color, determine that each chromatography marks original color.Such as, the gray-scale value of one of them chromatography mark is 0, so can determine that the shower nozzle spray printing that this chromatography mark is black by mass colour forms.
Step 207, according to each side-play amount, determine the adjustment direction and the adjustment amount that mark corresponding shower nozzle with each chromatography.
Particularly, determining between chromatography mark and shower nozzle after man-to-man corresponding relation, the side-play amount that can be marked by chromatography determines adjustment direction and the adjustment amount of corresponding shower nozzle.
Step 208, according to the adjustment direction of shower nozzle and adjustment amount, adjust the position of corresponding shower nozzle.
Particularly, after the adjustment direction determining each shower nozzle and adjustment amount, correspondingly can adjust the position of shower nozzle, thus improve chromatography precision.
More specifically, step 202 all can be performed by processor to step 207, and after the adjustment direction determining each shower nozzle and adjustment amount, processor can generate steering order, and steering order is exported to mechanical hook-up, is completed the adjustment of shower nozzle by mechanical hook-up.
