基于电磁超声的铁质文物特征提取方法研究
Research on Feature Extraction Method of Iron Cultural Relics Based on Electromagnetic Ultrasound
摘要
Abstract
Traditional cultural relics identification is usually based on personal experience,from the cultural relics material,appearance and other aspects of the authenticity of the identification,this method has some limi-tations.A feature extraction method of iron cultural relics is proposed relying on electromagnetic ultrasound with magnetostrictive effect to detect the characteristic parameters of iron cultural relics,based on the fact that the magnetostrictive properties of the material depend on the microstructure of the material.Based on the varia-tion curve of the amplitude of electromagnetic and ultrasonic signals with the intensity of the biased magnetic field,the characteristic parameters of the curve are extracted by stacked sparse autoencoder for the feature ex-pression of cultural relics,and support vector machine(SVM)classification algorithm is used for identification.The method is used to verify three different parts,and the detection accuracy reaches 93.3％.Therefore,this method is feasible for the identification of iron cultural relics.关键词
