The procedure functions in the compare between partial image of dynamic collection and corresponding image of the airscape. in chapter 5, basing on the analysis of correlative theory of digital image, we introduce the improved fasted - down algorithm and simulative anneal algorithm, which applies to nn calculation, an d bring forward the unique and effective means, correlative original value evaluation. basing on the combination of correlative arithmetic, a stable, high - speed and exact correlative arithmetic is formed, which makes it possible to apply computer vision detection of single - needle quilting in industrial production
本文展開研究並取得一定成效:構建了基於pci總線的微機實時圖像採集系統;在採集的布料總圖(鳥瞰圖)的基礎上,通過數字圖像的數字濾波、圖像增強、邊緣檢測等處理,提取布料圖像的邊緣,對輪廓的矢量化的象素點進行搜索,得到相應的圖案矢量圖,從而確定絎縫的加工軌跡,生成加工指令;在進給加工過程中,
