Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Such as Fig. 1, a kind of drawing method based on texturing methods or types of texture strokes style that first embodiment of the invention provides includes:
S101, selected digital image is obtained, and gray proces is carried out to selected digital image, obtain gray proces image.
S102, edge detection is carried out to the image subject in gray proces image, obtains image subject contour line；Wherein,
It include several inflection points on image subject contour line.
S103, using each inflection point as cut-point, image subject contour line is divided into several segments, obtains several sub- contour lines,
And path is delineated according to several sub- contour lines acquisitions are several.
S104, according to each line weight value for delineating path, be arranged it is each delineate path delineate mode；Wherein, it hooks
Picture mode includes: that paintbrush pushing height or lines delineate number.
S105, all pixels point gray value in image subject contour line is extracted, and according to preset gray threshold range,
All pixels point is clustered, several coloring color lumps are obtained.
S106, in each coloring color lump, carry out tiling arrangement by preset direction by the lines of preset length, establish
The coloring path of each coloring color lump, and each coloring number for colouring path is determined according to the gray value of each coloring color lump.
S107, basis delineate path, delineate mode, coloring path and colour the paint that number draws selected digital image.
For step S101, optionally, selected digital image be can be, but not limited to as mountain stone landscape image.Selected digital image can be with
For the photograph of live shooting or the image obtained from the network media.
Preferably, it is calculated by the following formula the gray value of each pixel of selected digital image, selected digital image is carried out at gray scale
Reason obtains gray level image；
F (i, j)=0.30R (i, j)+0.59G (i, j)+0.11B (i, j)；
Wherein f (i, j) is gradation conversion function, and i, j represent a pixel in the position of two-dimensional space vector, i.e., i-th
Row, jth column；R (i, j) is the i-th row, the R value in the rgb color mode of the pixel of jth column；G (i, j) is the i-th row, jth column
Pixel rgb color mode in G value；B (i, j) is the i-th row, the B value in the rgb color mode of the pixel of jth column.
Specifically, from the network media or being taken on site to mountain stone landscape image, calculated according to above-mentioned formula each in image
The gray value of pixel, value range 0-255 obtain the grayscale image of landscape image so that black-white-gray state is presented in image, from
And remove it is extra variegated in image, to improve the treatment effeciency of server.
Edge detection is carried out to the image subject in the stone image of mountain for step S102, specifically:, obtains selected mountain stone
The contour line of mountain stone in image, contour line at this time are irregular curves, and there are multiple inflection points.
For step S103, specifically: with the inflection point on the contour line of mountain stone in the stone image of mountain, as cut-point, by mountain
The contour line of stone is divided into several segments, obtains several cross-talk contour lines, and then, calculates the folder between two adjacent cross-talk contour lines
Angle merges two adjacent cross-talk contour lines if angle is less than preset value, and hooks the contour line after merging as one
Draw path；Otherwise, path directly is delineated using each sub- contour line as one；Then it obtains and several delineates path.
Preferably, preset value can be, but not limited to as any one value between 30 degree to 40 degree, specific value and can
It is adjusted according to the actual situation.Because traditional Chinese Painting is all the drafting of one section of one section of style of writing, by the way that the contour line of mountain stone is carried out
Segmentation forms so that the subsequent contour line to different sections carries out different processing and has discrepant style of writing.
It for step S104, is obtaining after several segments delineate path, according to each corresponding fringe region in path of delineating
The area ratio of color lump area and drawing area determines each line weight value for delineating path, further according to each line for delineating path
Thickness value, be arranged it is each delineate path delineate mode.
Preferably, the area of drawing area is the area of painting canvas or drawing paper.
Specifically, delineating there are two types of modes: it is optional, the first determine it is each delineate path to delineate mode as follows: will
Each line weight value for delineating path is compared with preset line weight value, and acquisition is each to delineate the corresponding paintbrush in path
Push height；Wherein, preset line weight value is that the pushing when area and paintbrush previously according to drawing area are painted is high
Degree, the calculated different thickness values for pushing the lines sketched out corresponding to height are preset according to picture in the actual operation process
The height pushed when size and the paintbrush drawing of cloth calculates lines when the corresponding paintbrush of 2~3 height delineates path
Thickness value sets 2~3 profile thickness value sections to correspond to the paintbrush pushing height for delineating path, according to obtained contour line
The thickness of item is worth pushing height when corresponding section setting paintbrush is started writing.
Optionally, second of determination it is each delineate path to delineate mode as follows:
Each line weight value for delineating path is compared with preset line weight value, acquisition is each to delineate path
Corresponding lines delineate number；Wherein, preset line weight value is, when the area and paintbrush previously according to drawing area are painted
Lines delineate number, and calculated lines delineate the thickness value of the lines sketched out corresponding to number.In actual operation, root
Corresponding 2~3 profiles of the thickness value for setting 2~3 sections according to the thickness value of lines delineate number, what thicker lines were delineated
Number is more.
The gray value of all pixels point of connected region inside mountain stone contour line, root are extracted for step S105, specifically:
According to multiple preset intensity value ranges, by all pictures of connected region inside the mountain stone contour line in same intensity value ranges
Vegetarian refreshments is clustered, and same color lump is classified as, to obtain several coloring color lumps.
For step S106, in each coloring color lump, by preset length lines by unified direction coloring color lump
Inside carries out tiling arrangement, obtains the coloring path of each color lump, further according to each coloring color lump gray value determine it is each
The coloring number in color path, such as: when presetting the section that gray value is 0-128, coloring number is 1 time, and gray value is
When 129-255, coloring number is 2 times, according to the gray value interval of each coloring color lump, to determine the coloring of each coloring color lump
Number.
For step S107, as shown in Figures 2 and 3, according to it is each delineate path and its it is corresponding delineate mode, draw every
One delineates the lines in path, draws out the profile diagram of selected digital image.
According to the coloring path of each coloring color lump and corresponding coloring number, the inside of the profile diagram of selected digital image is drawn
Texture then completes the drafting of the paint of selected digital image.
Specifically, obtained profile is delineated path, delineates mode, coloring path and coloring number, electric treatment letter is generated
Number control mechanical arm and more switching devices of configuration clamp different writing brushes, dip ink or pigment is painted, when drawing
The profile of mountain stone image is first drawn, then draws the texture of coloring coordinates measurement mountain stone image.
