Abstract: Provided are a method of manufacturing a terahertz detection device including detectors and lenses arranged in an array and a terahertz detection apparatus. An example method includes forming detectors in a first area of a first surface of a base substrate through a double-sided photoetching process to form a detector array, and providing at least one first alignment mark in a second area of the first surface of the base substrate. A plurality of lens mounting parts are formed in a third area of a second surface of the base substrate through the double-sided photoetching process, and at least one second alignment mark is provided in a fourth area of the second surface of the base substrate. The lenses are mounted to the lens mounting parts to form the detection device. The first alignment mark is aligned with the second alignment mark by using a double-sided photoetching machine.

Abstract: A method of millimeter-wave human body security checking based on double standing postures is provided, including: scanning and checking a body of a checked person in a first standing posture by using a millimeter-wave human body security detector, so as to obtain a first millimeter-wave human body image; scanning and checking the body of the same checked person in a second standing posture by using the millimeter-wave human body security detector, so as to obtain a second millimeter-wave human body image, wherein the second standing posture is different from the first standing posture (S10); and determining whether the checked person carries contraband based on at least the first millimeter-wave human body image and the second millimeter-wave human body image (S20). A system of millimeter-wave human body security checking based on double standing postures is provided, including: a millimeter-wave human body security detector (100) configured to: scan and check a body of a checked person in a first standing posture, so as to obtain a first millimeter-wave human body image, and scan and check the body of the same checked person in a second standing posture, so as to obtain a second millimeter-wave human body image, wherein the second standing posture is different from the first standing posture; and a processor (200) communicating with the millimeter-wave human body security detector (100) and configured to determine whether the checked person carries contraband based on at least the first millimeter-wave human body image and the second millimeter-wave human body image.

Abstract: Provided are a method and a device of binding security inspection information, an electronic apparatus and a storage medium, which may be applied to the field of security inspection technology. In the method of binding security inspection information of the present disclosure, the pedestrian detection frame is acquired by detecting the video stream, and each pedestrian detection frame has the coordinate information and the tracking information. According to the coordinate information and the tracking information of the pedestrian detection frame, the baggage security inspection information, the pedestrian security inspection information, and the identity information are bound to acquire all security inspection information of a detected person, so that a security inspection efficiency is improved.
