In the embodiment of the present application, there is a method for enhancing the effect of a millimeter-wave image. The steps of the method include: calculating the sampling position of the optical photographing system according to the preset association model according to the number of planar projection images of the collected millimeter-wave human body image; Based on the sampling position, the human body is optically photographed, the optical data of multiple images is obtained, and a three-dimensional model of the human body is constructed; based on the three-dimensional model, the scattering data of the human body in millimeter three-dimensional space is matched and fused to enhance the millimeter-wave image effect . The technical solution described in this application can improve the three-dimensionality of the millimeter-wave image of the human body in the millimeter-wave human body security imaging system, enhance the visual effect of the image, and facilitate the detection and identification of dangerous and suspicious items carried by the human body by security personnel.
Description
technical field [0001] The present application relates to the field of millimeter wave detection, and in particular to a method, device and computer-readable storage medium for enhancing the visual stereoscopic effect of millimeter wave images of the human body. Background technique [0002] With the application of close-range active millimeter-wave cylindrical scanning imaging systems in the field of human body security inspection, the millimeter-wave image of the human body is an important basis for judging whether the inspected person is carrying dangerous and suspicious items, and it is also an important basis for automatic detection algorithms in the human body security inspection system. How to effectively improve the visual effect of millimeter-wave images of the human body and make it easier for security personnel to judge the location of dangerous and suspicious items is a key technology in the 3D imaging system for millimeter human body security inspection.
