Document Type and Number:
Japanese Patent JP2022121058
Kind Code:
A
Abstract:
To enable effortless, versatile, and accurate anomaly detection.SOLUTION: An anomaly detection device is provided, comprising: a noise removal unit 36 configured to remove noise from each of a pair of brightness datasets 50 using a temporal median filter; a feature quantity computation unit 37 configured to divide highlight data into multiple local regions and compute a feature quantity for each local region; a learning input data generation unit 39 configured to generate learning input data 58 comprising multiple feature quantities associated with the local regions; detection input data generation unit 42 configured to generate detection input data 59 comprising the feature values computed based on the pair of brightness datasets 50 associated with the local regions; and an anomaly determination unit 43 configured to determine detection of an anomaly when a degree of abnormality of the feature quantity is equal to or greater than a threshold.SELECTED DRAWING: Figure 3
