In this paper, we propose an infrared camera anomaly detection system based on deep learning. In general industrial sites, infrared cameras are used for facility management. However, if something goes wrong with the infrared camera, recording stops and the status of the facility is unknown. Therefore, monitoring is necessary to prepare for this. Currently, only manpower is monitoring the camera.
However, there are limitations such as human error and mass inspection. To solve this limitation, we compare performance using AlexNet, VGGNet, ResNet, which are types of deep learning, and propose an automated monitoring method with better performance by comparing the captured original image and the histogram extracted image as a preprocessing process. The data set was collected and used by KEPCO's infrared night vision camera, and the results of training the data set with the VGGNet model and predicting the results were the best. The result is that the input image is judged to be normal/abnormal for the image captured at a certain period, and the model performance came out as Accuracy 0.97, Precision 0.97, Recall 0.97, F1-score 0.97. In addition, it was confirmed that the data set preprocessed with the histogram performed better.
