Package Summary

Implements a localizing jockey for the Large Maps framework (LaMa) based on a local costmap (costmap position is relative to the sensor but orientation is absolute). Implement a localizing jockey from a LaserScan. The associated descriptors are LaserScan[] and Crossing.

Overview

The lj_costmap package is a localizing jockey for the Large Maps Framework (LaMa) that computes place dissimilarities based on a local cost map, such as those obtained from the local_map package.

The role of this jockey is to get the dissimilarity of the lama_msgs/PlaceProfile descriptors of all vertices with the current place profile. The action is done when the dissimilarities are computed. Implemented actions:
