Problems solved by technology

Among them, metal detection gates cannot detect non-metallic contraband, such as ceramic knives, etc., and metal detection false alarms are high, and manual supplementary hand-held metal detectors are required for re-examination, which results in low security inspection efficiency and high labor intensity; micro-dose X-ray imaging Although the X-ray flying-spot scanning backscatter imaging technology has good imaging quality, it has the risk of ionizing radiation damage to the human body; although the millimeter-wave imaging technology has no ionizing radiation, the highest detection rate of automatic identification is only 85%, and it needs manual supplementation. Due to the limitation of resolution, the imaging quality is difficult to meet the requirements; the passive terahertz imaging security inspection has a simple structure, no radiation, no contact, no stay, but it cannot be used outdoors, and has high requirements for indoor temperature, light and other environments
[0003] The above-mentioned non-contact human body security inspection technologies all need to carry out coordinated security inspections in fixed security inspection channels, and at the same time need to be accompanied by "body search" inspections, which are not only inefficient but also suspected of violating privacy
For open non-cooperative target groups, it is impossible to distinguish in real time whether they carry controlled knives

Embodiment 1

[0047] figure 1 This is a flowchart of an authentication method provided in the first embodiment of the present invention. This embodiment can be applied to the situation of controlling tool authentication. The method can be executed by the authentication device in the embodiment of the present invention, and the device can use software and / or Realized by hardware, such as figure 1 As shown, the method specifically includes the following steps:

[0048] S110: Transmit a terahertz wave signal.

[0049] Among them, the terahertz wave is also called'life light', which is a kind of'light' energy, which refers to electromagnetic waves with a wavelength between 3μm and 1000μm, a frequency of 0.1-10THz, and between microwaves and infrared rays. . Terahertz waves not only have the same straightness as light, but also have penetration and absorption similar to radio waves. Traditional human fluoroscopy and radiography both use X-rays, but X-rays have side effects on the human body. Ter...

Abstract

The invention discloses an identification method and device, equipment and a storage medium. The method includes the steps that Terahertz wave signals are emitted; echo data corresponding to the Terahertz wave signals are received; the echo data are input into a target controlled knife identification model trained in advance, and according to an output result of a target controlled knife prediction model, a controlled knife identification result of an echo signal is determined, wherein the model structure and model parameters of the target controlled knife identification model are both determined by training the sample echo data. According to the technical schemes of the identification method and device, the equipment and the storage medium, non-perceptive detection and early warning of controlled knives concealed by human bodies at the open area can be realized, and the automatic detection rate of the controlled knives carried by non-cooperative target groups is increased.

Description

Technical field [0001] The embodiments of the present invention relate to computer technology, in particular to an authentication method, device, equipment, and storage medium. Background technique [0002] Currently, non-contact human security inspection technologies include metal detection gates, micro-dose X-ray imaging, X-ray flying spot scanning backscatter imaging, millimeter wave imaging, and passive terahertz imaging. Among them, the metal detection door cannot detect non-metallic contraband, such as ceramic knives. At the same time, the false alarm of metal detection is relatively high.
