Three-dimensional special-shaped planar aperture holographic imaging security radar optical reconstruction method

Abstract

The invention relates to the field of security check, particularly relates to security check by using a millimeter wave holographic imaging technology, and particularly provides a three-dimensional special-shaped planar aperture holographic imaging security check radar optical reconstruction method. The optical reconstruction method comprises the following steps: starting and initializing a three-dimensional point cloud measurement subsystem; enabling a plurality of cameras to collect human body optical photos, wherein all the collected human body optical photos form video monitoring data; judging whether to continue shooting or not; according to the video monitoring data acquired by the three-dimensional point cloud measurement subsystem, selecting a human body optical picture with the maximum human face information amount, and extracting human face data according to the human body optical picture with the maximum human face information amount. According to the invention, multiple different types of security check processes can be avoided, and security check steps are simplified; the data acquisition time of the system is shortened; the system is enabled to acquire multidirectional and multi-angle data information, the expandability of the whole system is further improved, and the usability and the detection environment adaptability of the system are enhanced.

Description

Technical field: [0001] The invention relates to the field of security inspection, in particular to the use of millimeter-wave holographic imaging technology for security inspection, and specifically provides a three-dimensional special-shaped plane aperture holographic imaging security inspection radar optical reconstruction method. Background technique: [0002] With the development of society and economy, airports, railway stations, subways, bus stations and other public transportation hubs have ushered in more and more passenger flows and logistics. The security inspection level of these areas must eliminate potential safety hazards to ensure public safety and meet With the high detection efficiency of fast passing, traditional security inspection technologies such as video surveillance, face recognition, body temperature detection, metal detection, and X-ray imaging have gradually failed to meet the demand. In recent years, developed countries in Europe and the United S...
