Abstract

The invention discloses an automatic detection and identification method for hidden articles. The method comprises the following steps of: performing millimeter-wave scanning on a detected person to obtain an original image; regulating the original image to obtain a target image; segmenting and locating parts of a human body according to the target image; generating a bar combination model; detecting a non-human body target according to the original image to obtain a non-human body target distribution original image; obtaining position distribution information of the non-human body target distribution original image relative to the human body through the bar combination model; and identifying the type of the non-human body target and displaying the position distribution information of the hidden articles relative to the human body. By the automatic detection and identification method for hidden articles provided by the invention, a manual mode of detection and identification for the hidden articles is changed to an automatic mode, demands on staff is lowered, human error is reduced, and the detection and judging time is shortened.

Description

technical field

[0001] The present invention relates to detection technology in the field of security inspection, and more specifically, the present invention relates to an automatic detection and identification method for concealed objects based on millimeter-wave imaging. Background technique

[0002] In the field of security inspection, there are many ways to detect the human body and its hidden objects: metal detectors, X-ray perspective, infrared detection, and millimeter wave detection. Metal detectors are realized by electromagnetic induction. They can only judge the presence or absence of metal objects, but cannot image or determine the location of objects. X-ray fluoroscopy equipment has a strong penetrability and is generally used for the detection of luggage items. If it is directly detected on the human body, it will be more dangerous to people, so it is generally rarely used for human detection in security inspections. Infrared detection uses the thermal radiat...
