Super-resolved Localisation without Identifying LoS/NLoS Paths
This paper focuses on the problem of localising a transmitting mobile station (MS) using multiple cooperative base stations (BSs). There are two technical difficulties: one is the data association between intermediate parameters and scatters; the other is to identify Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) paths. Our main contribution is a unified approach bypassing both data association and LoS/NLoS path identification. This is achieved by introducing virtual scatters and then a direct localisation formulation. Modern super-resolution technique is then adapted to cast the localisation problem as convex programming and solve it. Our approach addresses long-standing issues not completely solved in the literature, guarantees a global convergence, achieves good localisation accuracy and demonstrates its robustness to noise in our numerical tests.

NLOST: Non-Line-of-Sight Imaging With Transformer
Time-resolved non-line-of-sight (NLOS) imaging is based on the multi-bounce indirect reflections from the hidden objects for 3D sensing. Reconstruction from NLOS measurements remains challenging especially for compli…
DecoderSelf-Calibrating, Fully Differentiable NLOS Inverse Rendering
Existing time-resolved non-line-of-sight (NLOS) imaging methods reconstruct hidden scenes by inverting the optical paths of indirect illumination measured at visible relay surfaces. These methods are prone to reconstruct…
Inverse RenderingNon-line-of-sight Imaging with Partial Occluders and Surface Normals
Imaging objects obscured by occluders is a significant challenge for many applications. A camera that could "see around corners" could help improve navigation and mapping capabilities of autonomous vehicles or make searc…
Autonomous VehiclesDENALI: A Dataset Enabling Non-Line-of-Sight Spatial Reasoning with Low-Cost LiDARs
Consumer LiDARs in mobile devices and robots typically output a single depth value per pixel. Yet internally, they record full time-resolved histograms containing direct and multi-bounce light returns; these multi-bounce…
