Description

A kind of the winged of view-based access control model identification knits vamp automatic cutting method
Technical field
The present invention relates to the cutting methods for flying to knit vamp, and in particular to a kind of winged vamp of knitting of view-based access control model identification is cut automatically Segmentation method.
Background technique
Fly to knit vamp technology to be disposably to knit out the fabric of a shoes to come, substitutes multi-panel sewing machine technique.This Sample greatly increases the production efficiency of vamp, but it is rectangle or trapezoidal for knitting out the vamp come, it is also necessary to by shoes Facial contour is cut into.It is cut on the market usually using laser cutting machine, it is general to use manually to the method for film original text, swash Light can only walk fixed track, and worker requires for vamp to be directed at cutting track before cutting each time, and efficiency is extremely low, Gong Rengong Work amount is big.And fly to knit and do not knit out profile to be cut on vamp, the laser cutting machine of general vision guide can not be used It is cut.
Summary of the invention
Winged the object of the present invention is to provide a kind of identification of view-based access control model knits vamp automatic cutting method, is flying to knit vamp On add mark point, cutting track is automatically matched to fly to knit on vamp by the mark point and is cut.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of the winged of view-based access control model identification knits vamp automatic cutting method, fly to knit vamp to increase on cut-out with Vamp has the mark point P of contrast, increases mark point P' on film original text first with graphics software, and by film original text and Mark point P' is converted into trail file, is cut by laser and machine-readable the trail file is taken to obtain cutting track and mark point P' Location information, and relative coordinate of the cutting track on mark point P' is obtained by matrixing；Meanwhile passing through visual identity Technology obtains the location information for flying to knit the mark point P on vamp；Then by trail file mark point P' and fly to knit vamp figure The mark point P of on piece is corresponding, relative coordinate of the cutting track on mark point P' is carried out matrixing again, acquisition flies to knit shoes The cut point coordinate in face, laser cutting machine read cutting of the cut point coordinate realization for flying to knit vamp to flying to knit vamp.
The cutting method specifically includes the following steps:
Step 1, fly to knit vamp to increase position mark point P1 and bearing mark point P2 on cut-out, wherein position The centre of area position in vamp symmetrical center line and being located at vamp is arranged in tagging point P1；Bearing mark point P2 is arranged in shoes At position in the symmetrical center line of face and close to toe cap；
Step 2 increases position mark point P1' and bearing mark point P2' using graphics software on film original text, and should Film original text and position mark point P1' and bearing mark point P2' are converted into trail file；
Step 3, laser cutting machine read above-mentioned trail file, obtain cutting track and position mark point P1' and direction The location information of mark point P2', and cutting track is obtained in the relative coordinate of mark point by matrixing；
The coordinate vector of position mark point P1' is
P1'=[P1'x, P1'y]T
The coordinate vector of bearing mark point P2' is
P2'=[P2'x, P2'y]T
Then position and orientation matrix of the mark point in world coordinate system are as follows:
The coordinate vector of cutting track is Pi, then cutting track is Pj relative to the coordinate vector of mark point P1' and P2' =T1*Pi；
Step 4, the picture for obtaining and flying to knit vamp of being taken pictures by camera, in conjunction with Visual identification technology in the picture for flying to knit vamp The upper location information for obtaining position mark point P1 and bearing mark point P2；
The coordinate vector of position mark point P1 is
P1=[P1x, P1y]T
The coordinate vector of bearing mark point P2 is
P2=[P2x, P2y]T
Then position and orientation matrix of the mark point in world coordinate system are as follows:
Step 5 by the position mark point P1' in trail file and bearing mark point P2' and flies to knit the position on vamp picture Tagging point P1 and bearing mark point P2 is corresponding, and relative coordinate of the cutting track on mark point P1' and P2' is carried out again Matrixing obtains the cut point coordinate for flying to knit vamp, realizes cutting track and flies to knit the matching of vamp, flies the cutting for knitting vamp Point coordinate vector is Pt=T1*Pj；
Step 6, laser cutting machine, which are read, to fly to knit the cut point coordinate pair of vamp and flies to knit vamp and cut.
The present invention fly to knit vamp to add the mark point that there is contrast with vamp on cut-out, by the film Trail file is formed after increasing mark point on original text, laser cutting machine obtains mark point on film original text after reading trail file and cuts The location information for cutting track is added by Visual identification technology acquisition in the location information for flying to knit the mark point on vamp, will be luxuriant and rich with fragrance The mark point of woods original text is corresponding with flying to knit mark point on vamp, cuts so that cutting track is matched to and fly to knit on vamp, The cutting method saves artificial comparison process, improves production efficiency, guarantees the accuracy of cutting.
