The invention provides an imaging method, a terminal device and a computer storage medium. The imaging method comprises the following steps that: echo signals reflected from an object to be measured are received; data splicing is performed on first echo signals and second echo signals, so that first echo data and second echo data are obtained; Fourier transformation is performed on the first echodata and second echo data separately, so that first wave number domain data and second wave number domain data are obtained, phase compensation is carried out on the first wave number domain data andthe second wave number domain data separately, so that corresponding sampling data are obtained; three-dimensional interpolation processing is performed on first sampling data and second sampling dataseparately, so that first uniform sampling data and second uniform sampling data are obtained; inverse Fourier transformation is performed on the first uniform sampling data and the second uniform sampling data, so that a corresponding three-dimensional image is obtained, so that the three-dimensional image is projected, so that a two-dimensional image can be obtained. With the imaging method disclosed by the invention adopted, perfect and accurate security check data can be obtained, so that a complete imaging result is obtained.
Description
technical field [0001] The present application relates to the technical field of millimeter wave imaging, and in particular to an imaging method, a terminal device, and a computer storage medium. Background technique [0002] The millimeter-wave band signal, as a millimeter-scale band between far-infrared waves and microwaves, has the characteristics of penetrating plasma, dust, clothing and other objects, making its working band unlimited and harmless to the human body. Based on its related characteristics, the short-distance scanning imaging system based on the millimeter wave band can be applied to public places with a large flow of people such as airports and subways to perform safety monitoring and reduce the occurrence of dangerous situations; Accurate human body modeling, and its modeling results can be used in various scenarios such as animation production, custom clothing, 3D printing, etc., to meet the different needs of more industries. However, the short-distanc...
