Three-dimensional imaging method based on multi-perspective imaging

Abstract

The invention provides a three-dimensional imaging method based on multi-perspective imaging. The method includes the steps of firstly, generating N three-dimensional images of different angle ranges under the same Cartesian coordinate system; secondly, generating N window functions corresponding to the N three-dimensional images, and converting the N window functions from a cylindrical coordinate system into the Cartesian coordinate system; thirdly, respectively correspondingly multiplying the N three-dimensional images and the N window functions, and performing summation to obtain human body three-dimensional imaging data. The three-dimensional imaging method has the advantages that the 360-degree full-resolution three-dimensional imaging method is provided, a three-dimensional image contains 360-degree target information, the problem of resolution lowering of edge images is solved effectively, and rich, accurate and comprehensive information is provided for subsequent image processing.

Description

technical field [0001] The invention relates to the field of radar technology, in particular to a three-dimensional imaging method based on multi-view imaging. Background technique [0002] With the rapid development of radar imaging technology, the radar detection mode has gradually developed from the previous one-dimensional ranging to two-dimensional ranging angle measurement, synthetic aperture radar imaging (SAR), interferometric SAR, and three-dimensional planes with high resolution capabilities. Aperture 3D imaging and cylindrical aperture 3D imaging and other modes. In order to meet the increasingly urgent civilian and military needs, the detection accuracy of radar is getting higher and higher, and the imaging level is close to the optical level. [0003] The current cylindrical scanning imaging has gradually become the mainstream technology for human security inspection, and imaging is mostly carried out in the spatial domain or frequency domain. This imaging met...

Problems solved by technology

This imaging method has the following disadvantages: the resolution of the pixels in the middle part of the image is high, while the resolution of the edge part will decrease, and 360-degree full-resolution three-dimensional imaging cannot be realized, which truly reflects the information of the target, which is not conducive to subsequent image processing and target feature extraction
