摘　　要：在一定的环境中,材料腐蚀产物的颜色是获取材料腐蚀信息的一个重要指标,也是评价材料腐蚀等级的重要数据来源。在RGB空间中描述材料腐蚀产物的颜色特征,通过对腐蚀产物颜色特征的分割,确定各个腐蚀特征区域的大小,并计算各个腐蚀特征区域的R、G、B平均颜色值。通过建立材料腐蚀等级标准颜色图谱信息表,将每个腐蚀区域的腐蚀产物颜色值与标准颜色值进行相似度计算,通过机器识别得到每个腐蚀区域的腐蚀等级,最终计算得到整个材料的腐蚀等级,实现材料腐蚀程度的评定处理。In certain circumstances, the color of corrosion products is an very important index for obtaining the materials corrosion information. It is also an important data source to evaluate corrosion de-gree for materials. This paper represented the color feature of materials corrosion products in the RGB space, according to the segmentation of color feature, confirmed the size of every corrosion area, andcalculated the average color value of every corrosion area. Then it buih the map information table of standard colors for materials corrosion degree, and calculated corrosion products color similarity of every corrosion area, then got the corrosion degree of every corrosion area by machine recognition. Finally, it calculated the corrosion degree of the whole materials, realizing the evaluation for corrosiondegree of materials.
