Overview
The lj_laser package is a localizing jockey for the Large Maps Framework (LaMa) that computes place dissimilarities based on a 360-degree sensor_msgs/LaserScan.
The role of this jockey is to get the dissimilarity of the sensor_msgs/LaserScan descriptors of all vertices with the current place profile (represented by a sensor_msgs/LaserScan). The action is done when the dissimilarities are computed. Implemented actions:
GET_VERTEX_DESCRIPTOR: return the ids of the LaserScan descriptor and the computed Crossing descriptor
GET_SIMILARITY: return the dissimilarity based on sensor_msgs/LaserScan
