Abstract
The invention discloses a method for determining a marked line in a picture in a PLT format. A hole pattern graphic element and the marked line are needed to be processed in numerical control shock wave punching software, and marked line information contained in the picture in the PLT format can be quickly acquired. The method comprises the following steps of: inputting the picture to be converted in the PLT format, and reading line data in the picture in the PLT format; if the line is not closed, calculating the length of the line, and when the length of the line is greater than a set value, determining that the line is the marked line; and if the line is closed and the perimeter or area of the line exceeds the set value, determining that the line is the marked line. By the method, the conversion efficiency of identifying the marked line in the picture in the PLT format in the numerical control shock wave punching software can be effectively improved.
Description
Technical field
The invention belongs to field of image recognition, definite method of particularly a kind of PLT format picture setting-out lines in the numerical control vector graphical element transfer process.
Background technology
The numerical control surging and punching machine adopts to drive and impacts on rapidoprints such as leather apace towards mouth, thereby on materials such as leather, forms hole.Be the vestige that on the processing platen, stays setting-out in practical application, the operator places rapidoprint according to the vestige of setting-out.
In numerical control software, often need use the picture of PLT form.Include the lines data in the PLT format picture, can directly be used by digital control systems such as digital-controlled carving machines.But be to need to discern the setting-out line information that is comprised in the PLT format picture in software application such as numerical control surging and punching software.When software can not be discerned automatically, be to adopt by hand to mark the setting-out lines in softwares such as numerical control surging and punching at the PLT picture, this method speed is slow, and the location is inaccurate.But the setting-out lines in the accurate recognition PLT picture of also having no idea in the existing numerical control surging and punching software systems.
Therefore be badly in need of the computing method of the setting-out lines in the quick identification PLT picture in a kind of numerical control surging and punching machine software.
Summary of the invention

3) driving the numerical control punching machine processes by the setting-out line information after discerning successively.
Further, said 3) setting-out line information in identification and the definite PLT format picture in may further comprise the steps:
21): read the lines data in the PLT format picture, form lines array T2, make that N is the number of lines among the lines array T2, empty setting-out lines array T1;
22): judge whether N is 0, if, output setting-out lines array T1, end loop; If not, get into step 23);
23): read the N bar lines data of lines array T2, make N=N-1, judge whether these lines data are closed curve, if be non-closed curve, then get into next step) if closed curve then gets into step 26;
24): the lines length of calculating the lines data;
25): whether judge lines length greater than setting value th1, if, then be judged to be the setting-out lines, join setting-out lines array T1, if not, then return step 22);
26): lines perimeter L or the area A that lines enclose of calculating lines;
27): judge whether the lines perimeter L surpasses setting value th2 or whether area A that lines enclose surpasses setting value th3, if any condition is set up, then is judged to be the setting-out lines, joins setting-out lines array T1, and returns step 22);
28):, then be hole pattern unit, and return step 22) if neither set up;
Further, said setting value th2 is maximum perimeter Lmax, and said setting value th3 is maximum area Amax;
Wherein, Lmax representes that maximum identification aperture Dmax confirms to satisfy the maximum lines girth of pass condition, and Amax representes that maximum identification aperture Dmax confirms the maximum identification area; Lmax calculates through following formula: Lmax=3.14 Dmax; Amax calculates Amax=0.785*Dmax*Dmax through following formula;
Further, the value of said setting value th1 comes to confirm as the case may be;
Further, the value of said maximum identification aperture Dmax comes to confirm as the case may be.
The invention has the advantages that: the invention provides a kind of in numerical control surging and punching machine software; Automatically discern the computing method of setting-out lines from the PLT format picture; Can obtain the setting-out line information that is comprised in the PLT format picture fast, effectively improve the conversion efficiency of PLT format picture identification setting-out lines in the numerical control surging and punching software.
