Package Summary

Localizing jockey from LaserScan and absolute heading. Implements a localizing jockey from a LaserScan and absolute heading. The associated descriptors are sensor_msgs/LaserScan[] and lama_msgs/Crossing.

Overview

The lj_laser_heading package implements a localizing jockey that computes place dissimilarities based on a sensor_msgs/LaserScan and absolute heading. The behavior and properties are similar to those of the lj_laser jockey. The heading is given either as geometry_msgs/Pose or nav_msgs/Odometry.

The role of this jockey is to get the dissimilarity of the sensor_msgs/LaserScan descriptor 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:
