Description

The APP of 3D mural paintings method for designing and its application based on depth of field picture stitching algorithm
Technical field
The present invention relates to light source coloration ability analysis field, is specifically spelled based on depth of field picture based on color similarity Meet 3D mural paintings method for designing and its APP of application of algorithm.
Background technology
In recent years, bore hole 3D is drawn with the interaction of its special artistic expression, superpower vision impact and great entertaining Property is received more and more attention and is pursued, and covers advertisement, exhibition, and the multiple fields such as household, with vast potential for future development. 3D draw be according to artistic expression be segmented into mural painting, draw, draw wall, recessed corner draw etc..Wherein, 3D mural paintings pass through plane Perspective Principles and shadow relation produce visual impression and equilibrium sense illusion, so as to present the three-dimensional effect of virtuality on two dimensional surface Really.On design tactics, the main multiple picture superposition by the different depth of field, and appropriate shade is stamped, make one to arrive difference soon The same picture of the depth of field is so as to producing visual stereoeffect.
But only minority artist grasps the special anti-perspective design theory of 3D pictures, the works amount for causing 3D to draw is less. It is long that 3D draws the design cycle, and masses generally do not know about the pain spots such as 3D picture art and become and hamper this artistic development popularization.
For this purpose, the positive in addition research and innovation of the present inventor, has founded a kind of 3D mural paintings based on depth of field picture stitching algorithm Method for designing and its APP of application.
Content of the invention
Present invention is primarily targeted at proposing a kind of 3D mural painting methods for designing based on depth of field picture stitching algorithm, adopt The material picture for processing respectively, by realizing 3D mural painting Fast back-projection algorithms, the fresco works of synthesis based on depth of field picture stitching algorithm True to nature, be rich in aesthetic.
The secondary objective of the present invention is to propose a kind of 3D mural painting intelligent design APP based on depth of field picture stitching algorithm, real The ease of Use of existing 3D mural paintings synthesis.
For achieving the above object, the technical solution used in the present invention is:
Based on the 3D mural painting methods for designing of depth of field picture stitching algorithm, comprise the following steps:

B. background flatten:Concentrate from background picture and choose background picture, background picture is transformed into from RGB color HSI color spaces, are split to picture using maximum variance between clusters, to segmentation after threshold value under picture region adopt Mean filter carries out Fuzzy Processing;
C. the splicing of background and picture frame picture:Picture frame picture is chosen from picture frame pictures, adjusts the wide, high of picture frame picture Ratio, makes the size of wide, the high and background picture of picture frame coincide, then background picture is filled in picture frame, Background is realized Piece and the fusion of picture frame picture, form band picture frame background picture;
D. foreground picture and being superimposed with picture frame background picture:Foreground image is positioned at 4/5 position with frame background first, Again foreground image is merged with band frame background, the 3D mural paintings after being synthesized.
The stronger picture of the background picture material selectiong depth of field degree;Picture frame picture materials choose the annular picture frame without background Picture;Foreground picture material needs to choose the big picture of dynamic strong, near big and far smaller and contrast.
The background is specifically included with the splicing of picture frame picture:
Determine the wide and high of picture frame inner spare area domain:The midpoint of picture frame picture is taken, first is looked for afterwards up and down It is not transparent point, asks its difference to obtain height, it is not transparent point to look for first to the left and to the right, asks its difference to obtain width;
According to the height and width that tries to achieve, the height and width for adjusting picture frame picture makes it equal to the size of background picture;
Background picture is switched to 4 passages and navigates to the intermediate point of picture frame picture to obtain ROI region;
Background picture is filled into the fusion that ROI region completes background picture and picture frame picture finally.
The foreground picture with specifically include with being superimposed for picture frame background picture:
Size according to 4/5 pair of foreground picture with picture frame background picture size is adjusted;
ROI region is obtained at 1/5 position with picture frame background picture;
Foreground image is merged with band picture frame background picture using mask.
3D mural painting intelligent design APP, including:
