    摘要： The present disclosure provides a method and a system for inspecting goods. The method comprises steps of: obtaining (S21) a transmission image of inspected goods; processing (S22) the transmission image to obtain a suspicious region; extracting (S23) local texture features of the suspicious region and classifying the local texture features of the suspicious region based on a pre-created model to obtain a classification result; extracting (S24) a contour line shape feature of the suspicious region and comparing the contour line shape feature with a pre-created standard template to obtain a comparison result; and determining (S25) that the suspicious region contains a high atomic number matter based on the classification result and the comparison result.
