Abstract
The invention discloses a method for vectorizing an electricity drawing. The method comprises the following steps of: a, scanning an electricity drawing, and obtaining a black and white image by decoloring and sharpening; b, carrying out corrosion and expansion treatment on the black and white image and eliminating burrs and pits of the image; c, establishing an electric component vector template, and carrying out recognition on the black and white image and the components in the black and white image by using relevant measurements and then carry out template matching; and d, generating a vector diagram. In the method, the mode of image recognition and template matching is adopted to vectorize the electricity drawing, so that not only are the computation quantity and the conversion time reduced, but also the conversion accuracy is high, the error rate is greatly reduced, and the promotion value is very high.
Description
Technical field
The present invention relates to a kind of method of electric power drawing vectorization.
Background technology
The a variety of methods that raster pattern are converted into editable polar plot have been arranged in the prior art.The electric power drawing is the more special drawing of a class, has comprised a large amount of electric power components and parts in it, some technique of painting more complicated, it is big that the vector quantization that uses method of the prior art to carry out the electric power drawing not only has an operand, shortcomings such as transformation time is long, and transform low precision, the error rate height.
Summary of the invention
The objective of the invention is to provide a kind of simple, reasonable method, the electric power drawing is converted into polar plot.
In order to achieve the above object, technical scheme of the present invention is: a kind of method of electric power drawing vectorization, and this method may further comprise the steps successively:
A, the electric power drawing is scanned, through discolor, sharpening obtains artwork master;
B, artwork master is corroded and expansion process the burr of removal of images and pothole;
C, set up electric power components and parts vector template, adopt correlated measure that artwork master and components and parts are wherein discerned and carry out template matches;
D, generation polar plot.
The mode of employing image recognition and template matches is carried out vector quantization to the electric power drawing and has not only been reduced operand, has shortened transformation time, and transforms the precision height, and error rate greatly reduces, and has extraordinary promotional value.
Embodiment
Below in conjunction with embodiment the present invention is further specified.
A kind of method of electric power drawing vectorization, this method may further comprise the steps successively:
A, the electric power drawing is scanned, through discolor, sharpening obtains artwork master;
B, artwork master is corroded and expansion process the burr of removal of images and pothole;
C, set up electric power components and parts vector template, adopt correlated measure that artwork master and components and parts are wherein discerned and carry out template matches;
D, generation polar plot.
All simple distortion of making under the situation that does not break away from core of the present invention or modification all fall into protection scope of the present invention.
