DiffPhysCam: Differentiable Physics-Based Camera Simulation for Inverse Rendering and Embodied AI
Bo-Hsun Chen, Nevindu M. Batagoda, Dan Negrut
Generating synthetic images that closely mimic those from real cameras is instrumental in training visual models and enabling end-to-end visuomotor learning. We introduce DiffPhysC…
A physics-based sensor simulation environment for lunar ground operations
Nevindu M. Batagoda, Bo-Hsun Chen, Harry Zhang +2
This contribution reports on a software framework that uses physically-based rendering to simulate camera operation in lunar conditions. The focus is on generating synthetic images…
Enhancing Autonomous Navigation by Imaging Hidden Objects using Single-Photon LiDAR
Aaron Young, Nevindu M. Batagoda, Harry Zhang +4
Robust autonomous navigation in environments with limited visibility remains a critical challenge in robotics. We present a novel approach that leverages Non-Line-of-Sight (NLOS) s…
A Study on the Use of Simulation in Synthesizing Path-Following Control Policies for Autonomous Ground Robots
Harry Zhang, Stefan Caldararu, Aaron Young +8
We report results obtained and insights gained while answering the following question: how effective is it to use a simulator to establish path following control policies for an au…
Quantifying the Sim2real Gap for GPS and IMU Sensors
Ishaan Mahajan, Huzaifa Unjhawala, Harry Zhang +7
Simulation can and should play a critical role in the development and testing of algorithms for autonomous agents. What might reduce its impact is the ``sim2real'' gap -- the algor…
POLAR-Sim: Augmenting NASA's POLAR Dataset for Data-Driven Lunar Perception and Rover Simulation
Bo-Hsun Chen, Peter Negrut, Thomas Liang +3
NASA's POLAR dataset contains approximately 2,600 pairs of high dynamic range stereo photos captured across 13 varied terrain scenarios, including areas with sparse or dense rock d…
