The Pattern Recognition Of Non-Destructive Testing Based On HMM

摘要

A method of fault pattern recognition based on signal processing and characteristic reconstructed is presented in this paper. Hidden Markov model (HMM), which is initially employed in the field of speech signal processing is introduced into fault pattern recognition of non-destructive testing(NDT), which makes fault in aviation material reconstructed automatically the help of computer analysis and control system. It brings practical application for aviation material quality and safety use.
