【摘要】:液滴面積是表征材料表面憎水性的有效方法,因而介紹了適用于復合絕緣材料污層憎水性能狀態(tài)描述的液滴面積測量軟件開發(fā)流程,著重闡述了圖像識別液滴形態(tài)各個關鍵環(huán)節(jié)的核心算法。軟件開發(fā)的圖像處理環(huán)節(jié)采用拉普拉斯高斯算子,先以高斯低通濾波器平滑處理圖像信號,再以拉普拉斯算子高通濾波實現目標對象邊界提取。依據人工污穢試驗特點,合理設置灰度閾值等手段,將液滴圖像與背景圖像實現分離。并在此基礎上開展了復合絕緣子人工污穢試驗研究,以液滴面積最大值代表污層的憎水性能。研究表明使用LOG算子,并結合靛藍液滴,可以有效提高液滴面積法在污層憎水性能狀態(tài)描述中的精度,并可應用于復合絕緣子人工污穢試驗中憎水性的精細化分析。
[Abstract]:The droplet area is an effective method to characterize the hydrophobicity of the surface of the material. Therefore, the software development flow of droplet area measurement suitable for describing the hydrophobicity of the composite insulating material is introduced. The key algorithms for image recognition of droplet morphology are discussed. In the image processing of software development, Laplacian Gao Si operator is used to smooth the image signal, then Laplace operator high pass filter is used to extract the target object boundary. According to the characteristics of artificial contamination test, the drop image is separated from the background image by setting the gray threshold reasonably. On this basis, the artificial pollution test of composite insulator is carried out. The maximum of droplet area represents the hydrophobicity of the polluted layer. The results show that the LOG operator combined with indigo droplet can effectively improve the accuracy of the liquid drop area method in describing the hydrophobicity of the polluted layer and can be applied to the fine analysis of hydrophobicity in the artificial pollution test of composite insulator.
