Improved Kalman filter indoor positioning algorithm based on CHAN
Tongxin xuebao, 2023 Due to the raising complexity of the indoor environment, the influence of the non-line-of-sight error is gradually increasing in indoor positioning.How to reduce the non-line-of-sight error in the indoor positioning environment is particularly ...

Wireless sensor indoor positioning based on an improved particle filter algorithm
International Journal of Distributed Sensor Networks, 2020 Positioning by wireless sensor network is one of its main functions and has been widely used in many fields. However, when signal propagation is hindered, serious errors, non-line-of-sight errors, occur.

Onsite Non-Line-of-Sight Imaging via Online Calibration
IEEE Photonics Journal, 2022 There has been increasing interest in deploying non-line-of-sight (NLOS) imaging systems for recovering objects hidden behind corners. Existing solutions need to calibrate the imaging system using auxiliary apparatus and additional detectors.

, 2018 Random geometric graphs have been one of the fundamental models for reasoning about wireless networks: one places n points at random in a region of the plane (typically a square or circle), and then connects pairs of points by an edge if they are within ...

Few-shot Non-line-of-sight Imaging with Signal-surface Collaborative Regularization [PDF]
, 2022 The non-line-of-sight imaging technique aims to reconstruct targets from multiply reflected light. For most existing methods, dense points on the relay surface are raster scanned to obtain high-quality reconstructions, which requires a long acquisition ...

Fast back-projection for non-line of sight reconstruction [PDF]
ACM SIGGRAPH 2017 Posters, 2017 Recent works have demonstrated non-line of sight (NLOS) reconstruction by using the time-resolved signal frommultiply scattered light. These works combine ultrafast imaging systems with computation, which back-projects the recorded space-time signal to build a probabilistic map of the hidden geometry. Unfortunately, this computation is slow, becoming a
