摘　　要：针对复合材料结构检测损伤检测问题,本文提出了一种基于深度学习进行复合材料结构损伤检测的方法。本方法首先通过网络和文献收集复合材料结构图像资料,建立数据集,数据集包含损伤和未损伤的复合材料层合板图片;然后采用三个卷积神经网络模型AlexNet、VGG和ResNet对损伤情况进行自动分类;最后对三种预先训练过的网络架构的性能进行评估。实验结果表明,在相同的实验条件下,AlexNet技术使用相对较小的图像数据集,在合理的计算时间内能够成功地检测出损伤,且测试精度最高,复杂性较低。Composite structure detection technology has been exploring the efficient and fast damage detec-tion technology. In this paper, an image-based NDT technique is proposed to detect composite ma-terial damage by deep learning. A dataset containing damaged and non-damaged composite laminate images was established through the network and literature data. Then three convolutional neural network models AlexNet, VGG and ResNet were used to automatically classify the damage conditions. Finally, the performance of three pretrained network architectures is evaluated. The results show that AlexNet technology can successfully detect damage within a reasonable calculation time using a relatively small image dataset, with the highest test accuracy and low complexity.
