Embodiment Construction

[0020] The millimeter wave human body security detector is a common equipment in the field of human body security inspection. In practical applications, the millimeter wave security detector uses radar near-field imaging, and the system detects the measured human body through the emission, reflection and scattering of the human body or objects in the millimeter wave band. Or objects form a three-dimensional image, and hidden objects will appear in different forms on the image due to their different emission, reflection and scattering properties from the human body. However, in the existing technology, the imaging resolution of the millimeter-wave security detector is generally not high, and the signal-to-noise ratio is relatively low, and the cost of improving the imaging resolution by improving the hardware of the security detector is too high.

[0021] In order to solve the problems existing in the prior art, this application provides an image detection method applied to mill...

Abstract

The invention discloses a security inspection device and an image detection method thereof. The detection method comprises the steps that the security inspection equipment obtains at least one three-dimensional scanning image; the security inspection equipment projects the at least one three-dimensional scanning image to obtain a two-dimensional low-resolution image; the security inspection equipment carries out super-resolution reconstruction on the two-dimensional low-resolution image to obtain a two-dimensional high-resolution image, and the super-resolution reconstruction comprises reverseiteration projection; and the security inspection equipment displays the two-dimensional high-resolution image. In this way, under the condition that the hardware of the security inspection equipmentis not changed, the resolution of the security inspection equipment image is improved, the foreign matter detection and recognition rate of the security inspection equipment is increased, meanwhile,the false alarm rate is reduced, and the security inspection efficiency is improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a security inspection device and an image detection method thereof. Background technique [0002] At present, in the field of human body security inspection, the application of millimeter-wave human body security detectors is becoming more and more extensive. The millimeter-wave security detector uses radar near-field imaging, and the system detects the measured human body through the emission, reflection and scattering of the human body or objects in the millimeter-wave band. Or objects form a three-dimensional image, and hidden objects will appear in different forms on the image due to their different emission, reflection and scattering properties from the human body. [0003] However, in the existing technology, the imaging resolution of the millimeter wave security inspection instrument is generally not high, and the signal-to-noise ratio is relatively low. During th...
