Abstract: A method and a system of performing security inspection of human body based on millimeter-wave. The method includes: displaying, by a first display device, information related to a designated posture to a person to be inspected before the person enters an inspection channel defined by a millimeter-wave human body security inspection instrument, the designated posture being expected to be taken by the person when scanning the person with the instrument; guiding the person to enter the inspection channel and stand at a designated standing position within the inspection channel in a standing posture substantially complying with the designated posture; scanning, by the instrument, the person, to obtain millimeter-wave scanning data; and performing, by a workstation, a reconstruction of millimeter-wave scanning image of the person, a confirmation for the standing posture of the person, and a recognition of a suspected item of the person, based on the millimeter-wave scanning data.
