【摘要】：針對陶瓷閥芯表面缺陷特征復(fù)雜、嚙合表面存在研磨拋光區(qū)域等問題,現(xiàn)有基于視覺檢測的陶瓷閥芯表面缺陷檢測算法對不同種類陶瓷閥芯的適應(yīng)性較差且漏檢率高,該研究提出了一種分區(qū)域、多級優(yōu)化的陶瓷閥芯表面缺陷檢測算法。首先依據(jù)陶瓷閥芯表面反射率的不同,將其劃分為兩個(gè)檢測區(qū)域:拋光面(P)、非拋光面(Non P),然后根據(jù)陶瓷閥芯表面缺陷特征,將其分為兩類缺陷:G缺陷、C缺陷。在檢測過程中,搜索模板圖像金字塔信息,調(diào)整目標(biāo)灰度圖像位姿,經(jīng)掩模板(Mask)配準(zhǔn),提取出P區(qū)域、Non P區(qū)域,通過blob檢測、裂紋檢測,分別對P區(qū)域、Non P區(qū)域進(jìn)行缺陷提取。通過實(shí)驗(yàn)研究與系統(tǒng)設(shè)計(jì),分析了檢測算法的可行性、適用性,結(jié)果表明該研究算法針對不同種類陶瓷閥芯表面缺陷檢測漏檢率低,且能通過優(yōu)先級的合理設(shè)置,提高檢測效率。
[Abstract]:Aiming at the complex surface defects of ceramic spool and the problem of grinding and polishing area on meshing surface, etc. The existing ceramic spool surface defect detection algorithm based on visual detection has poor adaptability and high leakage rate to different kinds of ceramic spool. Multi-level optimization of ceramic spool surface defect detection algorithm. Firstly, according to the different surface reflectivity of ceramic spool, it is divided into two detection areas: polished surface Pao, non-polished surface Non P). Then according to the characteristics of ceramic spool surface defects, it is divided into two types of defects: G defect and C defect. In the detection process, the template image pyramid information is searched, and the target gray image pose is adjusted. The P region was extracted by mask Mask registration, and the P region was detected by blob, crack detection, respectively. Non P region for defect extraction. Through experimental research and system design, the feasibility and applicability of the detection algorithm are analyzed. The results show that the detection rate of different ceramic spool surface defects is low, and the detection efficiency can be improved by setting the priority reasonably.
