WebMay 3, 2024 · This work investigates the use of Neural implicit representations, specifically Neural Radiance Fields (NeRF), for geometrical queries and motion planning. We show that by adding the capacity to infer occupancy in a radius to a pre-trained NeRF, we are effectively learning an approximation to a Euclidean Signed Distance Field (ESDF). WebJan 4, 2024 · Signed Distance Function (SDF) [1] gives us a distance of point X from the boundary of a surface. The major advantage of this function is to determine if a point lies inside the boundary of the surface or outside the boundary. Property 1 states that the norm of the gradient vector of SDF is 1. For the SDF in Figure 1, the norm of the gradient ...
