CATNIPS: Collision Avoidance Through Neural Implicit Probabilistic Scenes

Timothy Chen, Preston Culbertson, Mac Schwager

We introduce a transformation of a Neural Radiance Field (NeRF) to an equivalent Poisson Point Process (PPP). This PPP transformation allows for rigorous quantification of uncertai…
