Multiple sensing fused portable hidden object imaging detection system

Abstract

The invention discloses a multiple sensing fused portable hidden object imaging detection system which comprises a millimeter wave imaging unit, an X ray back-scattering unit, a data fusion unit and adetermining and display unit; the millimeter wave imaging unit detects a target area, obtains a radar image in the target area, identifies a corresponding coordinate, and transmits an obtained data signal to the data fusion unit; the X ray back-scattering unit carries out imaging on the same target, obtains a back-scattering image in the target area, indicates corresponding coordinate information, and transmits the obtained data signal to the data fusion unit; the data fusion unit fuses a radar image with a back-scattering image according to coordinate information marked by the millimeter wave imaging unit and the X ray back-scattering unit, and outputs a complete image; and the determining and display unit makes a decision and outputs a decision result according to the image obtained bythe data fusion unit. The system has the advantages including simple and compact structure, convenient operation and good detection effect.

Description

technical field [0001] The invention mainly relates to the field of security inspection and security detection in the technical field, in particular to a multi-sensor fusion portable hidden object imaging detection system. Background technique [0002] The complex international security situation and the unbalanced and unequal development among regions have led to constant changes and upgrades of terrorist attacks and violent crimes around the world, posing a great threat to public security. In the detection of hidden contraband, various types of detectors will perceive the target in the detection space, and transmit the target information to the operator or monitor in different signal forms. The technical problems in the detection of these concealed prohibited dangerous goods urgently need to be solved quickly. And along with the development of technology, existing miniature wiretapping device, camera etc. have caused very big influence to the privacy of individual. [00...

AI Technical Summary

Problems solved by technology

[0008] 1. Metal detectors cannot image, and there are many false alarms. At the same time, the current optical fiber bugs use non-metallic materials, which cannot be accurately detected

[0009] 2. Although the millimeter wave has a certain penetration, it cannot image hidden objects hidden behind metal (such as water pipes in walls, etc.), and the detection signal for non-metallic hidden objects is weak; it is impossible to accurately find out all suspicious targets

[0010] 3. Conventional X-ray instruments basically adopt the form of cross-radiation, that is, the transmitting and receiving parts use separate modules. The disadvantage of this is that it needs to be aligned, and it is not suitable for handheld devices

But before that, my country did not have such products with independent technology. The use of some imported equipment in my country will be accompanied by various problems such as high price, high maintenance cost, slow maintenance response, inconvenient use training, and difficulty in upgrading and improving.
