Package Summary

The local_map package The local_map package takes as input a LaserScan message and outputs a local map as OccupancyGrid. The local map orientation is the same as the one of the global frame.

local_map provides a simple local cost map for several jockeys for the Large Maps Framework (LaMa). The map is centered on the frame of the laser range finder on which it is based but its orientation is fixed.

Overview

The image shows the map in player on the left and the local map obtained from the LaserScan (red dots) on the right. The robot's orientation is approximately 45° but the map's orientation is fixed.
