<p>A concealed dangerous articles detection method comprises: terahertz imaging on a measured object (S11); determining whether a suspicious area with the concealed dangerous articles exists or not in the terahertz images of the measured object obtained by terahertz imaging (S12); analyzing the suspicious area with the concealed dangerous articles with multi-wavelength spectrum analysis (S13); identifying whether the suspicious area contains the dangerous articles according to the measurement results of multi-wavelength spectrum analysis (S14); and outputting the terahertz images of the measured object and the detection results of the dangerous articles (S15). Also disclosed is a device for implementing the concealed dangerous articles detection method. The concealed dangerous articles detection method and device can identify the concealed dangerous articles from the perspective of both shape features and material composition, and greatly improve the detection accuracy.</p> |
