Abstract

本发明公开了基于毫米波雷达可微射频建模与超分辨率估计的物体三维重建方法，包括以下步骤：S1、采集目标物体的多视角低分辨率中频信号，并对信号进行静态环境干扰去除处理；S2、将低分辨率中频信号输入超分辨率信号估计网络，生成高分辨率中频信号；S3、对目标物体进行建模，并对射频高斯单元的空间几何参数及射频响应参数进行参数化；S4、仿真毫米波在发射、反射和接收过程中的衰减行为，并对射频高斯单元的衰减传播进行建模；S5、重建误差作为损失函数，对射频高斯单元的几何参数和射频响应参数进行迭代优化；S6、实现物体三维结构重建并避免无效单元过多带来的计算开销。本发明能够在低光照、遮挡等环境下实现物体的高精度三维重建。
