【摘要】：輪廓線的變點(diǎn)識(shí)別是質(zhì)量管理的研究熱點(diǎn)之一,當(dāng)前研究多以輪廓整體變化為識(shí)別對(duì)象,而對(duì)局部變化問題研究相對(duì)較少,且更少有在發(fā)現(xiàn)變異時(shí)間的同時(shí)能夠?qū)ふ业阶兓瘏^(qū)域在個(gè)體輪廓曲線上位置的系統(tǒng)方法。本文針對(duì)輪廓線局部變化識(shí)別問題,提出基于小波變換和聚類分析的方法。通過仿真性能評(píng)價(jià),并與現(xiàn)有方法進(jìn)行比較,結(jié)果顯示本方法能夠在更小的差異度檢測出變化并準(zhǔn)確定位變化區(qū)域。在文章的末尾,本文采用了一個(gè)實(shí)例對(duì)該方法的效果進(jìn)行驗(yàn)證。
[Abstract]:The variable point recognition of contours is one of the research hotspots of quality management. At present, most of the research focuses on the overall change of contours, but there are relatively few studies on the local change problems, and there are few systematic methods to find the position of the changing regions on the individual contours at the same time as the variation time is found. In this paper, a method based on wavelet transform and clustering analysis is proposed to solve the problem of local change recognition of contours. The simulation performance is evaluated and compared with the existing methods. The results show that this method can detect the change and accurately locate the change area at a smaller degree of difference. At the end of the paper, an example is used to verify the effect of this method.
