Abstract
本发明提供一种基于毫米波雷达的无人机三维环境建模方法和系统，利用毫米波雷达将优化毫米波信号发射至预设的植被区域中以得到植被区域反射信号；对植被区域反射信号的信号传播路径进行逆推，消除植被区域反射信号中的波形失真特征，生成消除失真后的反射信号；将消除失真后的反射信号与植被区域反射信号中的植被材质特征进行融合，生成预设的植被区域的三维结构特征；基于植被区域反射信号中的空间分布信息对三维结构特征进行空间重构，以生成预设的植被区域的三维空间模型；本发明实现了毫米波雷达点云数据到三维模型的直接物理转换，克服了传统建模中因植被信号干扰导致的模型空洞和材质混淆问题，提升了无人机在密集植被区域的场景感知精度。
