In this paper, we study the discrimination of road surface conditions based on deep learning using images captured by fixed-point cameras installed along roads (road surface images). In the case of classifying road surface images into categories corresponding to road surface conditions, there is the problem of imbalanced data since most of the road surface images belong to one category. The proposed method tackles this problem by applying the anomaly detection algorithm to road surface images, which aims to detect a small number of anomalous samples from a large number of normal samples. Then the anomalous sample group consists of road surface images belonging to multiple categories, and detailed classification in addition to anomaly detection can explain the reason why the road surface image is determined to be anomalous. General anomaly detection methods aim to only classify input samples into normal or anomaly categories, and any methods cannot classify detected anomalous samples into detailed categories. Then we propose a novel Classification-Aided Deep Convolutional Autoencoding Gaussian Mixture Model, which can detect anomalous samples and classify them into detailed categories for the discrimination of road surface images. The effectiveness of the model is verified by experiments using road surface images. |
