Abstract
En 中文
To solve the privation of crack information during feature transmission, we propose an automatic concrete infrastructure crack semantic segmentation method using deep learning. Initially, based on the statistical analysis results of crack images, a multi-stage feature extraction network is created with multi-resolution parallel transmission to extract the crack features. Then, the extracted features are aggregated according to the corre-lation between segmentation classes and pixels to enhance the localization performance of the model for cracks. Moreover, using statistical analysis results as constraints construct the loss function to optimize the model and overcome the data imbalance issue. Experiments are conducted on a self-made manual annotation dataset, which contains 2000 images from the dam, the bridge, and the spillway tunnel, and our method reach 94.51% Pre-cision, 86.39% Recall, 82.26% Intersection-over-Unions, and 90.27% F1_measure on the dataset. The experi-mental results show that the proposed method is optimal for the semantic segmentation of crack images.
