Abstract

The invention is applicable to the technical field of terahertz wave imaging, and provides an imaging method and device. The imaging method comprises the following steps of acquiring position information of a measured object at a first imaging position, and acquiring a three-dimensional position model of the measured object according to the position information; adjusting the first imaging position according to the three-dimensional position model of the measured object to obtain a second imaging position; and acquiring a terahertz wave signal reflected by the measured object at the second imaging position, carrying out three-dimensional image reconstruction based on the terahertz wave signal, and obtaining a three-dimensional image of the measured object. According to the method, the position of the imaging device is adjusted after the position information of the measured object is acquired, and then the corresponding terahertz wave signal is acquired to generate the three-dimensionalimage of the measured object, wherein the first imaging position and the second imaging position are set according to the preset motion track of the imaging device, so that the position information and the terahertz wave signal of the measured object can be acquired in an omni-bearing manner, and all-dimensional three-dimensional imaging of the measured object is realized.

Description

technical field [0001] The present application belongs to the technical field of terahertz wave imaging, and in particular relates to an imaging method and device. Background technique [0002] Terahertz wave is an electromagnetic wave band between infrared and microwave, usually 0.1THz ~ 10THz is defined as "THz Gap", that is, terahertz band. Electromagnetic waves in this band have both the directivity of visible light and the penetrating ability of microwaves. They have the characteristics of short wavelength, no ionizing radiation, and rich spectral information. (3D) stereo information, you can better get the three-dimensional image of the measured object. Therefore, how to use terahertz waves to perform omni-directional stereoscopic imaging of the measured object is an urgent problem to be solved at present. Contents of the invention [0003] Embodiments of the present application provide an imaging method and device, which can solve the problem of how to use teraher...
