Diameter range;
C. determining spacing range and pore diameter range are combined, and the corresponding spy is determined by the size in this feature region
The quantity of the pattern demarcation interval of sign and specific pattern, i.e., the collocation pattern of specific spacing/density and specific aperture;
D. in minimum area-encasing rectangle to characteristic area according to X, Y-direction is inquired point by point, if in characteristic area
Point, then inquire the gray scale, and pattern is specifically corresponded to by grey scale mapping;
E. spacing is obtained by pattern, finally determines punch position;
F. inquiry pattern obtains aperture, and affairs unitary relationship is constituted with punch position;
G. the processing technology information of the various point locations and aperture in record storage this feature region.By amplitude of variation with it is whole
Body brightness conditions identify the classification of this feature, so that it is determined that the integrated mode selected, by using flat in characteristic area
The size of equal brightness and standard deviation comes the spacing range in discrimination model and pore diameter range, and is combined, then by grey scale mapping
Specific pattern, and the punch position determined by specific pattern and aperture constitute business unitary relationship, between by changing direction, becoming
Away from, variable density, the mode for a variety of variables combination arrangement for becoming aperture, effective arrangement in the hole in feature is realized so that effect is more
Sample greatly improves image detail feature expressive ability, and shares a set of final Mapping standard between multiple features, it is ensured that protects always
The strong or weak relation between feature is held, the harmony that feature shows in image imaging process is effectively ensured.
It further illustrates, in the feature reconstruction of step (4), the outermost hole is using the center of characteristic area as coordinate original
Point establishes polar coordinates, and outermost hole is obtained along polar coordinates.Feature reconstruction is realized by obtaining outermost hole, and it is more to form feature
Side shape searches out the region of true hole arrangement to arrange offer condition to the hole of feature transition boundary, avoids between feature or special
Hole between sign and boundary interferes.The outermost hole can also be by using the center of characteristic area as coordinate origin, establishing
Bounding box establishes polar coordinates further according to bounding box, and outermost hole is obtained along polar coordinates.
It further illustrates, further includes using the maximum pitch of holes in characteristic area as offset in the feature reconstruction of step (4)
Distance deviates the characteristic polygon outward.By the outside offset-expanded of characteristic polygon to acquisition, boundary is effectively avoided
In punching and feature punching interfere or hole between the too small problem in gap.
It further illustrating, the borderline region described in step (4) between each characteristic area cuts transition boundary into strips,
Include the following steps:
A. image will be customized and the characteristic polygon of each reconstruct asks poor, obtain whole borderline region connection figure;
B. the boundary line for finding out characteristic area adjacent two-by-two, the angle point to define boundaries;
C. it rejects and repeats boundary angle point;
D. using each angle point as the severing position of boundary image, the whole borderline region connection figure is subjected to severing, is cut out
It is cut into strip transition boundary.Since in the entire scope of customization image, image detail characteristic area has passed through characteristic area
Hole arrangement is carried out in domain, and on the basis of the aperture machining information being extracted at the same time in characteristic area, its borderline region is cut
Transition boundary into strips, the transition border area be conducive between remaining each characteristic area are processed acquisition of information, from
And effectively determine hole arrangement.
It further illustrates, determines arrangement and the aperture in hole described in step (4) according to transition boundary, include the following steps:
A. the center of the characteristic area on acquisition transition boundary both sides, 2 lines, and using the direction of line as side
The hole arragement direction on boundary;
B. the average brightness of the respective fritter fringe region on transition boundary both sides is obtained, then seeks the average value of the two, really
Determine transition brightness;
C. border style table is inquired by the transition brightness, determines the size of transition border area internal orifice dimension;
D. hole arrangement, and record storage machining information are carried out to transition boundary along the plane coordinate system direction of customization image.
Since transition boundary is mainly excessive between carrying out each characteristic area, the transition border area is long and narrow, therefore (vertical along transition
Boundary) direction can receiving hole quantity it is few, be not necessarily to consider to become spacing or variable density thus, the arrangement mainly for hole is aligned
Direction and aperture account for, to realize the arrangement in the hole in transition boundary area.The progress hole arrangement includes that basis is cut
Transition boundary into strips seeks minimum area-encasing rectangle, and coordinate system is determined according to the long and short side of minimum area-encasing rectangle;It is surrounded in minimum
Boundary is inquired point by point according to hole arragement direction and coordinate system in rectangle, if the point of coincidence boundary, then inquires point ash
Degree, specifically corresponds to pattern by grey scale mapping, obtains spacing by pattern, determine punch position.
It further illustrates, step (2) further includes Image erosion, and described image corrosion is the size according to image to each spy
Sign region carries out quantitative corrosion and shrinkage characteristic zone boundary.It is for shrinkage characteristic region wherein to carry out the purpose of Image erosion
Boundary is polished with feature, characteristic area arrangement range interference is avoided the problem that, and at the same time removing the long and narrow or sharp row of being not easy
The feature corner of cloth processing, in order to effectively carry out in subsequent feature and the arrangement in the hole of transition boundary.
Further illustrate, step (1) if described in colored customization image color RGB image, then according to 0.11B+0.59G
+ 0.30R ratios are converted into gray scale picture;If the space picture of CMYK, HSV or YCbCr color is then first converted to the face of RGB
In the colour space, gray scale picture is converted into according still further to 0.11B+0.59G+0.30R ratios.To effectively be suitable for different types of coloured silk
Color customizes image, and gray proces are convenient and simple, and adaptability is wider.
It further illustrates, further includes the weight in the characteristic area after summarizing and the machining information of transition boundary in step (5)
New root is ranked up according to feature locations, and multiple portions are split into further according to pore size, generates complete artistic punching decorative panel
Manufacturing process information.The hole arrangement method is by shrinking characteristic area according to corrosion, arrangement, range of arranging expansion, cutting out
Except modes such as remaining boundary, boundary severing and boundary arrangements, taken into account to the full extent in feature and feature to realize
Edge has been effectively ensured image and has not occurred the problems such as boundary interference, boundary vacancy because selecting the mode of feature based, improved hole
The stability of decorative panel imaging.
