Paper Abstract

Pulsed lidar provides a simple direct measure of range that can be scanned to produce accurate 3D point clouds for modest computational cost. A simple implementation, however, can be subject to point-cloud artifacts particularly when sensing scenes with high dynamic range.

We discuss the origins of some of these artifacts and some possible mitigations. Of particular interest is range aliasing. By creating multiple hypotheses for the range of any given return a practical system may accurately and precisely classify aliased returns..
