KTH Longterm Dataset

KTH Scitos G5 robot - Rosie
The data was collected autonomously by a Scitos G5 robot with an RGB-D camera on a pan-tilt, navigating through the KTH office environment over a period of approximately 30 days. Each observation consists of a set of 51 RGB-D images obtained by moving the pan-tilt in a pattern, in increments of 20 degrees horizontally and 25 vertically. Waypoints are visited between 80 and 100 times and a total of approximately 720 observations are collected at the eight waypoints that can be seen in the figure below. The data is a part of the Strands EU FP7 project.

Dataset structure

The data is structured in folders as follows: YYYYMMDD/patrol_run_YYY/room_ZZZ , where: Each folder of the type YYYMMDD/patrol_run_YYY/room_ZZZ contains the following files: The room.xml file accompanying an observation contains the following (relevant) fields:

Parsing

A parser is provided here (can be installed with sudo apt-get install ros-indigo-metaroom-xml-parser) which reads in the data and returns C++ data structures encapsulating the low-level data from the disk. Form more information please refer to the parser README ( or here for a list of supported methods). Information about how to use the Strands package repository can be found here.

Download

This dataset is available for download in a single archive file (~ 300 GB). As an alternative, the individual folders and files can be obtained from here, and would have to be downloaded manually.
