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…
Ultrafast High-Flux Single-Photon LiDAR Simulator via Neural Mapping
Weijian Zhang, Hashan K. Weerasooriya, Stanley Chan
Efficient simulation of photon registrations in single-photon LiDAR (SPL) is essential for applications such as depth estimation under high-flux conditions, where hardware dead tim…
Joint Depth and Reflectivity Estimation using Single-Photon LiDAR
Hashan K. Weerasooriya, Prateek Chennuri, Weijian Zhang +2
Single-Photon Light Detection and Ranging (SP-LiDAR is emerging as a leading technology for long-range, high-precision 3D vision tasks. In SP-LiDAR, timestamps encode two complemen…
