钢桥涂装层对钢桥防腐至关重要，一般的涂装层检查可靠性较低，不利于钢桥的养护。针对该问题，采用多分辨率图像分类技术将多分辨率概念与空间灰度相关法、灰度差分法在多维空间进行了融合，运用空间灰度相关法与灰度差分法从图像中提取特征，产生一个多分辨率金字塔，采用最接近均值的重新分类算法进行聚类处理。图像处理结果与两次抽样方法在钢桥涂装检查评定过程中结合应用，可以提供准确的涂装层识别结果，便于进行缺陷率计算，为养护决策提供参考。
鋼橋塗裝層對鋼橋防腐至關重要，一般的塗裝層檢查可靠性較低，不利于鋼橋的養護。針對該問題，採用多分辨率圖像分類技術將多分辨率概唸與空間灰度相關法、灰度差分法在多維空間進行瞭融閤，運用空間灰度相關法與灰度差分法從圖像中提取特徵，產生一箇多分辨率金字塔，採用最接近均值的重新分類算法進行聚類處理。圖像處理結果與兩次抽樣方法在鋼橋塗裝檢查評定過程中結閤應用，可以提供準確的塗裝層識彆結果，便于進行缺陷率計算，為養護決策提供參攷。

Steel bridge Painting is very imPortant to steel bridge anticorrosive. The commonly used coating insPection has low reliability,which is not conducive to steel bridge conservation. SPatial gray level dePendence method and gray level difference method were combined in the multi-resolution Pat-tern classification with multi-resolution concePt. We extracted the image feature to Produce a multi-resolution Pyramid by sPatial gray level dePendence method and gray level difference method ,and a-doPted the reclassification algorithm which is close to the nearest mean to have clustering conducting. Combining the image results and subsamPling method in the steel bridge coating insPection assessment Process in order to Provide accurate recognition result of steel bridge coating. It facilitates the defect rate calculation,which lays a solid foundation for conservation decisions.
