DCT Maps: Compact Differentiable Lidar Maps Based on the Cosine Transform
Alexander Schaefer, Lukas Luft, Wolfram Burgard
Most robot mapping techniques for lidar sensors tessellate the environment into pixels or voxels and assume uniformity of the environment within them. Although intuitive, this repr…
A Maximum Likelihood Approach to Extract Polylines from 2-D Laser Range Scans
Alexander Schaefer, Daniel Büscher, Lukas Luft +1
Man-made environments such as households, offices, or factory floors are typically composed of linear structures. Accordingly, polylines are a natural way to accurately represent t…
An Analytical Lidar Sensor Model Based on Ray Path Information
Alexander Schaefer, Lukas Luft, Wolfram Burgard
Two core competencies of a mobile robot are to build a map of the environment and to estimate its own pose on the basis of this map and incoming sensor readings. To account for the…
