Technical Field
The invention relates to the field of image technology processing, in particular to an image stitching method in the printing industry.
Background
In the conventional printing process, the situation that the image provided by the customer is not matched with the printing format often occurs, as shown in fig. 1, because the printed image provided by the customer is smaller, the image is required to be spliced and then expanded to a proper printing format, and then the image is printed. As shown in fig. 2, the printed pictures provided by the clients are directly copied into a plurality of directly spliced pictures, but the left, right, up and down edges of the pictures have overlapping parts, if the pictures are naturally spliced without clipping, the patterns at the position a of the edges of the two pictures can be seen from the enlarged view of the spliced part shown in fig. 3 to generate the condition of irregular splicing, so that the picture effect after printing can be greatly influenced. The traditional processing method is that drawing staff adopts a manual mode to carry out drawing repairing treatment, the processing efficiency is low, the drawing repairing effect is not ideal enough, and time and manpower are wasted.
Disclosure of Invention
The invention aims to overcome the defects and provide a judging method for whether patterns in printing can be spliced or not and a pattern splicing method. By the method, whether the patterns to be printed can be spliced and expanded or not can be rapidly judged.
The invention is realized by the following technical scheme: a judging method for judging whether patterns in printing can be spliced or not comprises the following steps:
acquiring a pattern to be printed;

and according to whether the splicing line can be found on the pattern to be printed, the result is used as a basis for judging whether the pattern can be spliced or not. The range of the similarity a between the color value of each pixel point on the reference line and the color value of each pixel point on the spliced line is as follows: 0% < a +.100%. In order to achieve the best splicing printing effect, the color values of the pixel points on the reference line and the splicing line are completely consistent with the color values of the pixel points on the reference line.
And according to whether the splicing line can be found on the pattern to be printed, the result is used as a basis for judging whether the pattern can be spliced or not.
Further, the acquiring the color value of each pixel point on the reference line on the pattern to be printed specifically includes: and calculating the color value of each pixel point by adopting a straw algorithm, and globally analyzing the same module.
The invention also provides a pattern splicing method in printing, which comprises the following specific steps:
acquiring a pattern to be printed;
selecting an arbitrary point on the pattern to be printed, and drawing an arbitrary straight line passing through the point as a reference line to obtain color values of all pixel points on the reference line on the pattern to be printed;
finding another stitching line along any direction from a datum line on a pattern to be printed, and determining the stitching line as an available stitching line when the similarity between the color value of each pixel point on the stitching line and the color value of each pixel point on the datum line on the pattern to be printed reaches a preset standard;
and according to whether the splicing line can be found on the pattern to be printed, the result is used as a basis for judging whether the pattern can be spliced or not. The range of the similarity a between the color value of each pixel point on the reference line and the color value of each pixel point on the spliced line is as follows: 0% < a +.100%. In order to achieve the best splicing printing effect, the color values of the pixel points on the reference line and the splicing line are completely consistent with the color values of the pixel points on the reference line.
After the splice lines are found on the patterns to be printed, reserving the patterns between the reference lines and the splice lines as first splice units, and copying a plurality of required splice units; and the reference line or the spliced line is used as the spliced edge of each spliced unit to splice so as to meet the requirement of pattern splicing.
Furthermore, in order to enrich the artistic effect brought by different splicing modes, the splicing units can be directly connected together or connected together after mirror images.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a judging method for judging whether patterns in printing can be spliced or not and a pattern splicing method, by the method, whether the patterns to be printed have ductility can be judged quickly by using a computer program, and because pictures provided by customers can not necessarily meet the breadth requirement in actual printing, if a picture unsuitable for splicing and extending is subjected to manual pattern repair treatment, the accuracy of the patterns provided by the customers can be damaged, and the method is time-consuming and labor-consuming and has poor effect. Meanwhile, the invention can also rapidly judge whether the image meets the expansion condition by judging whether the similarity of the color values of each pixel point on the datum line and the splicing line reaches the preset standard or not, and rapidly realize the expansion and use of the image by arranging the splicing unit.
