Airport concrete pavement crack repairing method

The invention discloses an airport concrete pavement crack repairing method which comprises the following steps: acquiring concrete pavement image information, and realizing first diagnosis and identification and second diagnosis and identification of image information crack defects based on a crack identification model, a PNN model and an SVM model for identifying cracks, crack widths and crack depths; on the basis of the first diagnosis identification and the second diagnosis identification, based on ultrasonic scanning, carrying out migration imaging on the crack and the fracture hole, and obtaining clear representation of a crack and fracture hole image; and performing targeted repair according to the three diagnosis results. 本发明公开了一种机场混凝土道面裂缝修补方法，包括采集混凝土道面图像信息，基于裂缝识别模型、PNN模型和SVM模型，实现对图像信息裂缝缺陷的第一次诊断识别和第二次诊断识别，用于识别裂缝、裂缝宽度和裂缝深度；并在第一次诊断识别和第二次诊断识别的基础上，基于超声扫描，对裂缝缝洞进行偏移成像，得到裂缝缝洞图像的清晰表征；根据三次诊断结果，进行针对性的修复。
