FAECCD-CNet: Fast Automotive Engine Components Crack Detection and Classification Using ConvNet on Images

نویسندگان

چکیده

Crack inspections of automotive engine components are usually conducted manually; this is often tedious, with a high degree subjectivity and cost. Therefore, establishing robust efficient method will improve the accuracy minimize inspection. This paper presents approach towards crack classification, using transfer learning fine-tuning to train pre-trained ConvNet model. Two deep convolutional neural network (DCNN) approaches training classifier—namely, via (1) Light architecture from scratch, (2) fined-tuned top layers architectures AlexNet, InceptionV3, MobileNet—are investigated. Data augmentation was utilized over-fitting caused by an imbalanced inadequate sample. improved index 4%, 5%, 7%, respectively, for proposed four approaches. The achieved better recall precision scores. fine-tuned features MobileNet attained classification thus classifiers. Moreover, we employed up-to-date YOLOv5s object detector detect region. We obtained mean average (mAP) 91.20% on validation set, indicating that model effectively distinguished diverse part cracks.

A novel underwater dam crack detection and classification approach based on sonar images

Underwater dam crack detection and classification based on sonar images is a challenging task because underwater environments are complex and because cracks are quite random and diverse in nature. Furthermore, obtainable sonar images are of low resolution. To address these problems, a novel underwater dam crack detection and classification approach based on sonar imagery is proposed. First, the...
