檢測牆面塗料顏色均勻度之圖像分析法

Application of Digital Image Processing in Analyzing the Uniformity of Paint Color Coated on a Wall Surface

摘要


本文在於探討應用數位相機與圖像處理技術來評量牆表面塗料均勻度的圖像分析法。實驗樣品圖像用數位相機拍得後,進行RGB與HSV顏色模型的分色處理,並分別通過濾波、均量化與正規化處理後,再統計顏色像素值的標準差、變異數、均方差與峰值信噪比等,據此來檢驗採用圖像處理方法的合適性。實驗統計結果顯示,採用中値濾波與正規化HSV顏色模型的圖像處理法,可以有效地提高檢測方法的可靠度。在實務應用上,本文的檢測方法可以快速地檢測分析牆表面塗料顏色分佈的均勻程度,施工人員可據此進行噴塗補強改善。

This paper presents an application of a digital camera and the techniques of digital image processing (DIP) in automatically analyzing the uniformity of paint color coating on a wall surface. The DIP methods such as filter process, equalization and normalization were individually considered to enhance the quality of test images. The experimental results demonstrate that the combination of median filter and normalization of HSV color space are helpful for promoting the reliability of analyzing the uniformity of paint color coated on a wall surface, which also shows the practicability of the presented method.
