Description

This repository contains a collection of maps from four different environments. For each environment, a set of sensor-based occupancy-like map is provided. These sensor map are collected as 3D meshes with a Google Tango tablet with the Constructor application provided by Google.

Each 3D mesh is horizontally sliced and converted to occupancy-like map. It should be mentioned that due to instability of the Constructor application in handling big meshes, some maps (mostly office maps) only cover the upper half (along z-axis) of the environment in order to increase the coverage of individual maps. Sensor maps vary in their global consistency and coverage of the area. In addition, a single layout map (in bitmap format, occupancy-like) is also provided for each environment. This table provides details for each set, followed by a thumbnail overview of all maps.

Note on mesh to occupancy map conversion: Due to the absence of sensor's trajectory and pose, identifying the open space and the conversion from mesh format to occupancy map has been done manually in an interactive process. This process also included manual filtering (eg. noise removal). As a consequence, the conversion is not deterministically reproducible. Generating a pseudo trajectory-pose state for sensor over each map, could make it possible to setup an automated procedure for the conversion. Such a procedure also requires a 3D point cloud filtering to result in a smooth occupancy map.

Annotation Scripts and GUIs

In order to run accompanied scripts for ground truth annotations or visualization of the annotations, the following dependencies must be met:

numpy >= 1.10.2
matplotlib >= 2.0
PySide >= 1.2.1
scikit-image >= 0.12
opencv >= 2

Most dependencies (except for opencv) could be installed by:

git clone https://github.com/saeedghsh/Halmstad-Robot-Maps.git
cd Halmstad-Robot-Maps
pip install -r requirements.txt

Instructions on how to use scripts will come soon.
