The present application provides an imaging method, a terminal device and a computer storage medium. The imaging method includes: receiving the echo signal reflected from the measured object; performing data splicing on the first echo signal and the second echo signal to obtain the first echo data and the second echo data; Perform Fourier transform on the echo data and the second echo data to obtain the first wave number domain data and the second wave number domain data, and perform phase compensation on the first wave number domain data and the second wave number domain data respectively to obtain corresponding sampling data ; Carry out three-dimensional interpolation processing on the first sampled data and the second sampled data respectively, obtain the first uniformly sampled data and the second uniformly sampled data; respectively carry out inverse Fourier transform on the first uniformly sampled data and the second uniformly sampled data to obtain The corresponding three-dimensional image is projected to obtain a two-dimensional image. The imaging method of the present application can obtain complete and accurate security inspection data, thereby obtaining a complete imaging result.
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...
