【摘要】 基于对桥梁裂纹图像特征的深度分析,综合应用图像连通区域检测和图像边缘检测等数字图像处理技术,研发了一套基于现代数字图像处理理论的远距离非接触式裂纹几何尺寸图像识别系统。户外条件下对在役桥梁裂纹检测的对比试验结果表明,该系统对于桥梁微小损伤的远距离无损检测具有较高的工程应用价值。更多还原

【Abstract】 Based on the analysis of the characteristics of images of bridges’ cracks,some special image processing algorithms,such as the edge detection,were used in order to obtain the cracks length and width.As the result of study,based on modern image processing theory,one completed system that including hardware and software was developed.The compared test of the existing bridge with cracks under the out-door environment shows that the new technology is suitable to do the long distance non-contacted crack detection of bridge structure.更多还原
