Markov-Renewal Single-Photon LiDAR Simulator
Weijian Zhang, Prateek Chennuri, Hashan K. Weerasooriya +2
Single-photon LiDAR (SP-LiDAR) simulators face a dilemma: fast but inaccurate Poisson models or accurate but prohibitively slow sequential models. This paper breaks that compromise…

Real-Time Markov Modeling for Single-Photon LiDAR: Acceleration and Convergence Analysis
Weijian Zhang, Hashan K. Weerasooriya, Prateek Chennuri +1
Asynchronous single-photon LiDAR (SP-LiDAR) is an important imaging modality for high-quality 3D applications and navigation, but the modeling of the timestamp distributions of a S…

Parametric Modeling and Estimation of Photon Registrations for 3D Imaging
Weijian Zhang, Hashan K. Weerasooriya, Prateek Chennuri +1
In single-photon light detection and ranging (SP-LiDAR) systems, the histogram distortion due to hardware dead time fundamentally limits the precision of depth estimation. To compe…
