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. The optical reconstruction method includes the following steps: starting and initializing the three-dimensional point cloud measurement subsystem; multiple cameras collecting optical photos of the human body, and all the collected optical photos of the human body form video monitoring data; judging whether to continue shooting; measuring the sub-system according to the three-dimensional point cloud From the video monitoring data acquired by the system, select the optical photo of the human body with the largest amount of face information, and extract the face data according to the optical photo of the human body with the largest amount of face information. The present invention can avoid multiple different types of security inspection processes, simplify the security inspection steps; reduce the time for the system to obtain data; enable the system to obtain multi-directional and multi-angle data information, further improve the scalability of the entire system, and enhance the usability and detection environment of the system adaptability.
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...
