摘要
通过图像识别技术对水工钢结构的腐蚀形貌特征及分布状况进行定量化研究,并通过室内实验对图像识别技术进行验证。结果表明:通过对腐蚀图像进行灰度处理、二值化处理可以实现对水工钢结构腐蚀形貌及腐蚀分布的准确性描述。
The morphology and distribution of corrosion in a hydraulic steel structure were quantitatively studied using the image identification technology. Laboratory experiments were conducted to verify this technology. The results show that image gray processing and binary processing can accurately describe the morphology and distribution of corrosion in the hydraulic steel structure.
