论文摘要
环境场景的重建对于自动机器人应用引起了极大的兴趣，因为必须准确表示环境以确保与机器人的安全互动。同样重要的是，确保机器人与其控制器之间的可靠通信也至关重要。大型智能表面（LIS）是一项由于其通信能力而被广泛研究的技术。此外，由于天线元件的数量，这些表面是无线电传感的有力解决方案。本文提出了一种新颖的方法，可以将在LIS获得的无线电环境图转换为沿其区域散布的散点机建造的室内环境的平面图。利用了基于最小二乘（LS）方法，U-NET（UN）和条件生成对抗网络（CGAN）来执行此任务。我们表明，可以使用本地和全球测量值正确重建平面图。
Environmental scene reconstruction is of great interest for autonomous robotic applications, since an accurate representation of the environment is necessary to ensure safe interaction with robots. Equally important, it is also vital to ensure reliable communication between the robot and its controller. Large Intelligent Surface (LIS) is a technology that has been extensively studied due to its communication capabilities. Moreover, due to the number of antenna elements, these surfaces arise as a powerful solution to radio sensing. This paper presents a novel method to translate radio environmental maps obtained at the LIS to floor plans of the indoor environment built of scatterers spread along its area. The usage of a Least Squares (LS) based method, U-Net (UN) and conditional Generative Adversarial Networks (cGANs) were leveraged to perform this task. We show that the floor plan can be correctly reconstructed using both local and global measurements.
