Embodiment 1

[0035] The computer-aided splicing method for color patterns of the invention is used for splicing modules with colored patterns and straight edges. Below in conjunction with embodiment, specifically illustrate its operation step:

[0036] 1. Scan. Such as image 3 In , there are a total of 3 colored puzzle modules that need to be spliced ​​together. Number them, and the numbers of the three modules I, II, and III in the figure are 1, 2, and 3, respectively. The shapes of the jigsaw puzzle modules are all isosceles right triangles, in which the length of the right-angled side of module 1 is 13.8 cm, the length of the hypotenuse of module 2 is 27.6 cm, and the length of the right-angled side of module 3 is 13.8 cm. Number the edges of each jigsaw module in turn, the specific numbers are as follows image 3 shown. The three jigsaw puzzle modules are scanned sequentially under the same scanning conditions, and converted into color graphics in digital format. Pay special att...

Abstract

The invention discloses a computer-assisted mosaicing method for color patterns and belongs to the technical field of computer image processing. The method comprises the steps of scanning, coding, pairing, simulation mosaicing and real-object mosaicing, wherein n scanned mosaicing modules and edges of mosaicing modules are numbered, points are sampled at equal intervals at edges, color codes of sampled points are extracted, data are established, color codes of edges having the same point sampling number are matched to judge whether edges are paired, and real mosaicing is conducted. According to the method, color information of edge characteristic points and edge lengths serve as mosaicing evidences, and initial screening is conducted with edge information length matching serving as the first condition for mosaicing, so that the time for mosaicing computation is saved.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a computer-aided splicing method for color patterns. Background technique [0002] In production and life, people need to splice and restore some fragments into complete graphics, such as splicing and restoration of flat materials such as metal sheets, important paper documents that have been shredded due to misuse, and banknotes. But the splicing work is cumbersome, and the amount of labor increases exponentially with the number of fragments. Manual splicing is time-consuming and laborious. In fact, most of the stitching time is spent on repetitive tasks such as comparison, trial stitching, and adjustment. However, due to the large number of human-involved components, splicing errors often occur due to human factors (such as human fatigue). [0003] The fragment assembly problem has several characteristics. First of all, in most cases, it is impossible to p...
