1. A convolutional neural network based on an improved residual structure is proposed to detect and classify pavement defects using RGB-thermal images.
2. The proposed model has a prediction accuracy of 98.88%, fewer parameters, shorter training time, and higher recognition accuracy compared to existing image classification models.
3. A visualization method incorporating gradient-weighted class activation mapping (Grad-CAM) is proposed to analyze the classification results and compare the data the model learns from the images under different input data.
