DATA & FILE OVERVIEW
---------------------

1. File List
   A. Folder: vis       
      Short description: Contains extracted data from the VIS camera as annotated MATLAB Level 5 MAT files.
        
   B. Folder: raw-data       
      Short description: Contains raw-data in form of ros bagfiles.

   C. Folder: calibration       
      Short description: Contains calibration information.


2. Relationship between files: The image data contained in the folders were extracted from various rosbags, which were recorded in Koblenz and the surrounding area on November 18,2016. The images were extracted from the dataset about every 4 seconds, preprocessed and then saved. The masks were created with an annotation tool developed for this purpose. The data streams of the cameras were synchronized with the help of a hardware trigger.

METHODOLOGICAL INFORMATION
--------------------------


1. Description of methods used for collection/generation of data: 
The cameras used for the recording are two special multi-spectral cameras from Ximea:
- MQ022HG-IM-SM4X4-VIS
- MQ022HG-IM-SM5X5-NIR

The recording was synchronized via a hardware trigger consisting of an Arduino board.
The data streams were recorded with Ubuntu 14.04 and ROS-Indigo and stored as rosbags.
The Rosbags are raw data that have to be pre-processed specially.
