摘要: 混凝土结构随着服役时间的增长,产生的裂缝会不断扩展并可能对结构造成损伤。因此,裂缝检测对于混凝土结构健康监测有着重要意义,但超声及基于人工视觉等传统检测方法无法大量快速地对裂缝进行分类检测。为此提出一种基于移动网络(MobileNetV2)轻量级卷积网络和谷歌张量流图(TensorFlow)深度学习框架的混凝土结构裂缝快速识别分类的预测模型。首先,基于路径库存(pathlib)方法对数据进行提取并划分数据集;其次,基于迁移学习的数据增强对数据集进行扩充;再次,在TensorFlow框架下利用深度学习的接口(Keras)来构建卷积网络的池化层等;最后,建立构建完整卷积网络架构并输出结果。试验结果表明:模型收敛时,预测精度达到0.997 5,训练时间仅为710 s,可以为工程现场的移动设备检测提供帮助。

Abstract: With the increase of service time of concrete structures, the generated cracks will continue to expand and may cause damage to the structure. Therefore, crack detection is of great significance for the health monitoring of concrete structures, but traditional ultrasonic and artificial vision-based detection methods can not quickly classify cracks. Based on MobileNetV2 lightweight convolutional network and TensorFlow deep learning framework, a prediction model for rapid identification and classification of concrete structure crack was established. Firstly, the data set was extracted and partitioned based on the pathlib method; secondly, data enhancement based on transfer learning expanded the data set; thirdly, based on the TensorFlow framework, Keras was used to build the pooling layer of the convolutional network; finally, a complete convolutional network architecture and obtained the results were obtained. The test results showed that the model converged, the prediction accuracy reached 0.997 5, and the training time was only 710 s. It could provide help for mobile equipment detection in the project site.-
