Problems solved by technology

[0005] However, the existing millimeter-wave human security inspection technology still has the following shortcomings: first, millimeter-wave imaging is greatly affected by ambient light, high-temperature body and cold air distribution, and air temperature; second, the use of a single millimeter-wave imaging device When scanning the whole body from all angles of the human body, the inspected personnel need to rotate on the spot to cooperate with the inspection, which brings inconvenience to the inspected personnel and reduces the pass rate; third, the dynamic millimeter wave image of the human body has complex shapes and cannot be directly used as the basis for automatic alarm

Abstract

The invention discloses a pass-type human body safety inspection system. Inspected people accept safety inspection through an inspection channel. According to the pass-type millimeter wave human body safety inspection system, the whole body of the inspected people can be scanned dynamically to obtain human wave millimeter wave images and optical images, and therefore inspection of forbidden objects hidden in human garments and automatic alarm can be achieved.

Description

Technical field [0001] The present invention relates to the field of human body safety inspection, in particular to a pass-through human body safety inspection system, which obtains human body millimeter wave images and optical images by scanning the entire body of the inspected person, and realizes inspection and automatic inspection of prohibited items hidden in human clothes Call the police. Background technique [0002] Common human body security inspection equipment mainly includes metal detectors, trace inspection instruments, and X-ray transmission equipment. Among them, metal detectors are only sensitive to detecting metal substances; trace inspection instruments are only effective for detecting explosives and drugs; X-ray transmission equipment detects metal / non-metal objects, explosives, drugs, etc., and can have higher Spatial resolution and certain scanning speed, but because X-ray ionizing radiation is harmful to human health, its use in human security inspection is...
