Millimeter wave three-dimensional holoscan imaging device and human or object checking method

Abstract

The present invention discloses a millimetre wave three dimensional holographic scan imaging apparatus and a method for inspecting a human body or an article. The apparatus comprises a first millimetre wave transceiver module, a second millimetre wave transceiver module, a first guide rail device to which the first millimetre wave transceiver module is connected in slidable form, a second guide rail device to which the second millimetre wave transceiver module is connected in slidable form, and a driver configured to drive the first / second millimetre wave transceiver module to move along the first / second guide rail device, wherein the first scan performed by the first millimetre wave transceiver module and the second scan performed by the second millimetre wave transceiver module both are plane scans. They may improve scan speeds and accuracy, simplify scan operations and enhance the flexibility of the apparatus.

Description

technical field [0001] The invention relates to the technical field of human body security inspection, in particular to a millimeter-wave three-dimensional holographic scanning imaging device and a method for using the millimeter-wave three-dimensional holographic scanning imaging device to inspect a human body or an object. Background technique [0002] At present, the most widely used imaging human body or object security inspection technology is mainly X-ray imaging technology and millimeter wave imaging technology. Moreover, millimeter wave imaging technology is increasingly recognized by the market. Millimeter wave imaging technology is mainly divided into passive millimeter wave imaging technology and active millimeter wave imaging technology, and active millimeter wave imaging technology is mainly holographic imaging technology. [0003] Among the active millimeter-wave 3D holographic imaging technologies used in human body security inspection, cylindrical scanning i...

AI Technical Summary

Problems solved by technology

[0003] Among the active millimeter-wave 3D holographic imaging technologies used in human body security inspection, cylindrical scanning imaging technology is widely used, but its equipment is bulky and its algorithm is complex, and its algorithm is obtained after approximate processing in theory , so the imaging accuracy cannot be guaranteed

In addition, cylindrical scanning can only use a vertical antenna array, which is longer and has more antenna units, which greatly increases the cost of the equipment

[0004] The active millimeter-wave 3D holographic imaging device with single-sided scanning can only inspect one side of the inspected person at a time. To complete a comprehensive inspection of the inspected person, two scans are required, and the inspected person needs to turn around between the two scans. , the security check process is more complicated and slower
