摘要/Abstract

摘要：

为实现对目标空间结构的高精度重构，提出一种基于多视角逆合成孔径雷达图像的雷达目标三维重建方法。首先，对目标进行回波建模。然后，采用方向性的高速特征检测与旋转不变特征描述算法对预处理后的目标逆合成孔径雷达图像进行特征点匹配，并利用奇异值分解进行目标散射点三维重建；结合几何一致性验证，剔除误匹配点，减小重建误差。最后，通过多视角图像的多轮重建修正，提升三维重建的准确度，得到较为完整、清晰的目标三维像。仿真验证了该方法的有效性。

Abstract:

To achieve high-precision reconstruction of the target spatial structure, this paper proposes a radar target 3D reconstruction method based on multi-view inverse synthetic aperture radar （ISAR） images. Firstly, echo modeling is performed on the target. Then, oriented features from accelerated segment test and rotated binary robust independent elementary features （ORB） algorithm is used to match the feature points of the preprocessed ISAR image of the target. Singular value decomposition （SVD） is used to reconstruct the three-dimensional scattering points of the target. Combined with geometric consistency verification, false matching points are eliminated to reduce reconstruction errors. Finally, through multiple rounds of reconstruction correction of multi view images, the accuracy of three-dimensional reconstruction is improved, and a relatively complete and clear three-dimensional image of the target is obtained. The simulation verifies the effectiveness of the method.

Key words: radar target, multi-view inverse synthetic aperture radar image, feature point matching, three-dimensional reconstruction
