1. A computer-implemented method comprising:
receiving, by one or more processors, a plurality of Light Detection and Ranging (LiDAR) scans captured by a LiDAR sensor of a portable device as the portable device travels on a path through an environment;
processing the plurality of LiDAR scans to generate a LiDAR path signature that is representative of the path of the portable device through the environment; and
providing the LiDAR path signature as an output,
wherein the portable device, another device, or a combination thereof captures a plurality of subsequent LiDAR scans of an environment in a given area until a subsequent LiDAR path signature generated from the plurality of subsequent LiDAR scans matches the LiDAR path signature of the first portable device within a threshold matching criterion.
