- Abstract:
-
To address the problem that existing methods rely predominantly on single-view radar images while ignoring the complementary multi-view information of three-dimensional ground penetrating radar, a road subsurface crack identification method based on multi-view fusion and deep learning was developed. A three-dimensional forward model of asphalt pavement was established using gprMax to obtain B-scan, C-scan, and D-scan radar profiles from three orthogonal directions, and a dataset comprising 3 437 triple-view samples was constructed by combining forward simulation with field measurement data. DenseNet121 and ResNet50 were adopted as backbone networks, with a Squeeze-and-Excitation channel attention mechanism introduced, a triple-branch parallel structure constructed, and an inter-view attention fusion module designed for adaptive weighted fusion of multi-view features. Experimental results showed that the DenseNet121-TB model achieved accuracy, precision, recall, and F1-score of 98.60%, 98.71%, 98.60%, and 98.65%, respectively, with accuracy 4.19 percentage points higher than that of the best single-view model. Ablation experiments verified the positive contribution of each module to recognition performance. Field core drilling validation demonstrated good correspondence between the three-view features and the drilling results, indicating that the proposed method has practical engineering applicability.
