ActiveCN106055885ADimension eliminationImprove separabilitySpecial data processing applicationsInformaticsData streamAnomaly detection
The invention provides an anomaly detection method of flight data of an unmanned aerial vehicle based on over-sampling projection approximation basis pursuit. The method introduces the signal sub-space projection approximation thought during over-sampling and signal processing and detects anomaly of dataflow by estimating and pursuit matching of base vector direction of the data projection approximation subspace after over-sampling and utilizes the feature of subspace direction insensitive to the switching of flight modes in order to inhibit influence on flight modes on the anomaly detection result. Therefore, a framework for an on-line anomaly detection method for flight data of the unmanned aerial vehicle is provided. The detection framework lowers its false drop data by over 53.82% compared with four on-line anomaly detection methods such as Online-MD, BN, CCA and KOAD during on-line anomaly detection of flight data on the condition of consuming the same Mu-s calculating time. The detection accuracy AUC is improved by over 5.28% and reaches 0.9836, close to the theoretical value of 1. The method is capable of effectively solving the problem of one-line anomaly detection of flight data.
