【摘要】：隨著計算機科技的進步,人工智能領域的發(fā)展,應用于紡織業(yè)的紋織CAD技術也朝著自動化、智能化的方向發(fā)展。在此背景下,本文設計了一套完整的紋織CAD系統(tǒng),系統(tǒng)集成了彩色像景混色算法,同時為紋織圖像編輯引入了矢量輔助和多圖層技術。本文提出了一套全新的應用于彩色像景設計的彩色像景混色算法,研究了混色理論在彩色像景設計中的應用,用若干種紗線顏色作為基色混合出數(shù)十萬種不同顏色,解決了彩色像景CAD分色技術中只能使用全緯線顯色結構和紗線擠壓的問題,實現(xiàn)了彩色像景設計流程的完全自動化。與彩色像景CAD分色技術相比,顏色數(shù)量多25%,占用內存由4GB減小至1GB,計算速度提高30倍左右;并且不依賴于GPU,僅僅使用PC級CPU便可在10秒以內完成一幅千量級像素位圖的計算。本文還在彩色像景混色算法中提出了一種紗線顏色自動選擇的方法,通過分析紋織圖像在HSV顏色空間的色調信息,解決了紗線顏色選擇問題,實現(xiàn)了紗線顏色自動選擇的功能。同時,本文提出了適用于紋織圖像的輪廓矢量化算法,通過矢量輪廓來劃分紋織圖像的區(qū)域,解決了紋織圖像區(qū)域分割和描述的問題,使得紋織圖像中不同的區(qū)域能夠運用不同的組織結構,形成紋理不同的織物效果;本文還研究了多圖層技術在編輯中的應用,使得紋織圖像處理能夠多次運用,減少設計師的工作的重復率。本文在Windows環(huán)境下實現(xiàn)了以上功能,程序代碼由C++完成,并引入了應用程序開發(fā)框架Qt和圖形設備接口 GDI+,利用其中的2D圖形庫輔助開發(fā)。
[Abstract]:With the progress of computer technology and the development of artificial intelligence field, the jacquard CAD technology applied in textile industry is also developing towards automation and intelligentization. Under this background, a complete jacquard CAD system is designed in this paper. The system integrates color image mixing algorithm, and introduces vector assistant and multi-layer technology for jacquard image editing. In this paper, a new color image blending algorithm for color image design is proposed. The application of color mixing theory in color scene design is studied. Several yarn colors are used as primary colors to mix out 100,000 different colors. The problem that color structure of full weft line and yarn extrusion can only be used in color image CAD separation technology is solved. Compared with the color image CAD color separation technology, the number of colors is more than 25, the occupied memory is reduced from 4 GB to 1 GB, and the calculation speed is increased about 30 times. The calculation of a thousand magnitude pixel bitmap can be completed within 10 seconds by using PC CPU, which is independent of GPU. In this paper, a method of automatic yarn color selection in color image blending algorithm is proposed. By analyzing the hue information of jacquard image in HSV color space, the problem of yarn color selection is solved, and the function of yarn color automatic selection is realized. At the same time, an algorithm of contour vectorization suitable for jacquard image is proposed in this paper. By dividing the region of jacquard image by vector contour, the problem of segmentation and description of jacquard image region is solved, which makes different area of jacquard image can use different structure and form different texture effect of fabric. This paper also studies the application of multi-layer technology in editing, so that the jacquard image processing can be used many times, and reduce the repetition rate of designer's work. This paper realizes the above functions under the Windows environment, and the program code is completed by C, The application development framework QT and the graphic device interface GDI are introduced, and the 2D graphics library is used to assist the development.
