Study on material identification method based on X-ray dual-spectrum
Aiming at the detection needs of substances in the fields of industrial production,material science,safety inspection,etc.,the research on the identification method of X-ray dual-spectrum substances has been carried out.A dual-spectral identification algorithm model for different substances is proposed.The boundary substance definition and pseudo-color algorithm are introduced into the model,which can preliminarily determine the type of substances.An X-ray dual-spectrum transmis-sion experiment system was built,X-ray dual-spectral images of complex backgrounds and various ob-jects were measured,and the influence of substance definition algorithm and pseudo-color algorithm on the discrimination of substance types was studied.Based on this,the algorithm model is optimized,and the preliminary identification of substance types is realized flexibly and quickly,which is of great significance for industrial non-destructive testing and rapid screening of security inspections.
