http://helenol.github.io/ WebDec 28, 2024 · Gradient-based planners are widely used for quadrotor local planning, in which a Euclidean Signed Distance Field (ESDF) is crucial for evaluating gradient magnitude and direction. Nevertheless, computing such a field has much redundancy since the trajectory optimization procedure only covers a very limited subspace of the ESDF …

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). http://helenol.github.io/publications/iros_2024_voxblox.pdf

WebDescription. D = bwdist (BW) computes the Euclidean distance transform of the binary image BW . For each pixel in BW, the distance transform assigns a number that is the distance between that pixel and the nearest nonzero pixel of BW. [D,idx] = bwdist (BW) also computes the closest-pixel map in the form of an index array, idx.
