Description

A kind of method of the complicated grain pattern of efficient vector quantization ancient building
Technical field
The present invention relates to the side of a kind of pattern vector method, more particularly to a kind of complicated grain pattern of efficient vector quantization ancient building Method.
Background technology
Ancient building is the product of ancient times people's crystallization of wisdom and practical activity, carries abundant history, culture, art The information of aspect, is the important material in kind for studying its residing period.Ancient building is valuable matter input, with can not Reproducibility, once being destroyed, can cause heavy losses.Some grain patterns especially on ancient building, even more a kind of history culture Succession, therefore we need a kind of means by ancient building grain pattern carry out conversion form vector quantization electronic document, for research, Repair, the accurate scientific basis of offer is provided.
Existing most common ancient building grain pattern vectorization method, is all the form by cad software Freehandhand-drawings, this CAD The Normal practice that software is built to vector line segment is, it would be desirable to which the figure of construction carries out folded bottom, is positioned manually and draws sample Bar curve and camber line, drawing process need constantly to adjust radian with mouse right and left key, and this way is by mouse sensitivity Limitation, is only applicable to the figure situation relatively low compared with simple, required precision.When facing compared with complex figure, because curve is more, sample Bar curve adjustment difficulty is increased, and to the hypotaxia of figure, causes the efficiency reduction drawn.Therefore, painting based on CAD software There is following defect in method processed：1. input tool limited flexibility, precision is relatively low；2. it is low to draw efficiency, lines need to be entered repeatedly Row check and correction and adjustment.
The content of the invention
Goal of the invention：To solve the defect of prior art, a kind of side of the complicated grain pattern of efficient vector quantization ancient building is now provided Method, carries out figure Freehandhand-drawing with reference to Digitizing plate and coordinates R2V softwares to change, not only vector quantization precision is high, and can be efficiently quick Conversion.
Technical scheme：A kind of method of the disclosed complicated grain pattern of efficient vector quantization ancient building, including following step Suddenly：
The setting of drawing tool：Digital panel device is accessed into computer input, coordinates PhotoshopCS6 mapping softwares to carry out line Sample Freehandhand-drawing, vector quantization conversion is carried out using vector lines software R2V is turned；
Ancient building grain pattern is obtained：Ancient building grain pattern pattern is downloaded by shooting or network, the requirement of its definition is：Level and hang down Straight resolution ratio is more than or equal to 72dpi；
Grain pattern is drawn：The new files in PhotoshopCS6, file size is divided by understanding that ancient building grain pattern graphics details are defined Resolution is more than or equal to 200dpi, and the ancient building grain pattern figure drawn the need for acquisition is towed in new files, adjusts artwork Size is presented with details facilitates drafting to be advisable, and the newly-built layer of transparent figure layer on figure selects pressure sensi-tive pen and sets brush to be hard Bian Yuan, size is 4 ~ No. 5, and color is set to black, and lines of outline is carried out according to graphics shape on Digitizing plate using pressure sensi-tive pen Print, lines should keep smooth and round and smooth, and reduce the original style and features of grain pattern as far as possible, and Freehandhand-drawing is formed after bitmap lines, closes figure Figure layer where shape .jpg forms are stored as by Freehandhand-drawing figure layer；
Data conversion：The .jpg files of storage are imported into R2V softwares, operation menu bar image → conversion → 24 RGB → gray scale Order, completes first step conversion, the menu bar vector → Automatic Vector that reruns → source images selection is CAD diagram shape, Ran Houdian Hit and proceed by image vector, finally run and output vector file is selected in menu bar file option, its type is .dxf lattice Formula；
CAD is imported to use.
The digital panel device is WACOM PTH-851 models, and pressure sensi-tive pen is 1024 grades.
A kind of method of the disclosed complicated grain pattern of efficient vector quantization ancient building, it would be desirable to the complex figure of drafting Freehandhand-drawing in Photoshop CS6 softwares is positioned over to generate；By using computer entry device Digitizing plate, pressure sensi-tive pen, pen are utilized Brush selects to be hard-edge circle, and Brush Size is 4 to No. 5, and color is set to black, the artificial print of figure progress to needing structure；Draw Cloth pixel is typically chosen in more than 200dpi, to ensure the presentation of details；Print goes out after graph outline lines and stored on painting canvas For .jpg forms；And 24 RGB gray scale pictures are converted to R2V softwares, rear automatic vectorization turns to .dxf formatted files and led Enter CAD software to use.
Digitizing plate is applied in the drafting of ancient building grain pattern, using Digitizing plate electromagnetic induction principle, when pressure sensi-tive pen nib is moved Cutting magnetic field produces electric signal when dynamic, and is accurately read signal by multipoint positioning, so as to carry out lines drafting, face compared with During complex figure, many curvilinear structures can effectively be depicted using pressure sensi-tive pen, realize and efficiently draw, for turning for vector quantization Change, the conversion of vector graphics is realized using R2V softwares.
Beneficial effect：The method of the disclosed complicated grain pattern of a kind of efficient vector quantization ancient building, with reference to Digitizing plate The accurate drafting of complicated grain pattern can be realized, and is converted into vectorizations algorithms, accurate data is provided for follow-up study reparation.
