The system comprises a flying-spot forming unit configured to output beams of X-rays, a plurality of discrete detectors which are arranged vertically along a human body to be inspected, and a controlling unit coupled to the flying-spot forming unit and the plurality of detectors, and configured to generate a control signal to control the flying-spot forming unit and the plurality of detectors to perform a partition synchronous scan on the human body to be inspected vertically. The present disclosure utilizes the geometry property of the human body back-scattering inspection system, and proposes a multiple-point synchronous scan mechanism which largely accelerates the inspection of human body.

    摘要： The present invention discloses a three-dimensional data processing and recognizing method. It comprises following steps of: scanning and reconstructing objects to be detected so as to obtain three-dimensional data for recognition of the objects to be detected; extracting data matching to features from the three-dimensional data, so that the extracted data constitute an interested target; with respect to the data matching to features, merging and classifying adjacent data points as one group, to form an image of the merged interested target; recognizing a cross section of the interested target; cutting the interested targets by at least one perpendicular plane which passes through a central point of the cross section and is perpendicular to it, in order to obtain a graph; and recognizing shape of the interested targets based on property of the graph.
