Drone-Dataset Tools

The goal of this repository is to make using drone datasets as easy as possible. Therefore, we provide source code in Python for import and visualization. Thus, this source code not only allows to visualize trajectories and thus get an overview, but also serves as a template for your own projects.

Installation and Quick Start

1. Create a new Python environment or select a pre-existing one. This code is tested with Python 3.8, but is very probably compatible with newer releases of Python.

   If you use Anaconda3, this can be done as follows:

   conda create --name drone-dataset-tools38 python=3.8
   conda activate drone-dataset-tools38

2. Install required packages by navigating to the root directory and using

   pip3 install -r requirements.txt

3. To run the visualization tool, first, navigate to the src/ directory

   cd src

4. Then to visualize e.g. recording 26 from the exiD dataset, either copy the content of the dataset's data/ directory into the data/ subdirectory of this repository and use

   python3 run_track_visualization.py --dataset exid --recording 26

   or you can skip the data copying and directly provide the path to the dataset's data/ directory by using the --dataset_dir command line option:

   python3 run_track_visualization.py --dataset_dir /<path/to>/exiD-dataset-v2.0/data/ --dataset exid --recording 26

   See below for further explanations.

Importer

tracks_import.py

This module allows to import the tracks, tracks meta info and recording meta info for a single recording (read_from_csv(tracks_file, tracks_meta_file, recordings_meta_file)) or for all recordings (read_all_recordings_from_csv(base_path)).

Visualizer

The visualizer imports the data and visualizes them on an image of the recording site. The user may visualize specific frames or just playback the recorded tracks. In addition, information like the track id or speeds may be displayed (see "Command-line Options").

Each road user class has its own color: cars are light blue, vans are purple, buses are orange, trucks are orange, pedestrians are red, bicycles are yellow and motorcycles are yellow.

By clicking on track, a separate window is created with plots of the clicked track's positions, headings, velocities and accelerations.

• If additional columns (i.a. leadDHW, leadTTC, ...) are present in the *_tracks.csv, these are shown in the pop-up window instead.
• If surrounding vehicle ID columns (i.e. leadId, rearId, ...) are present in the *_tracks.csv, the corresponding vehicles are colored in the visualization. These are also updated during playback.
  (Hint: Use the --suppress_track_window argument to quickly check the surrounding vehicles of several tracks without opening a lot of track windows)

The following shortcuts are currently implemented:

Keyboard Shortcut	Description
space	Play/Stop the playback
right arrow	Jump to next frame
left arrow	Jump to previous frame

Command-line Options

The command-line options can be used when starting the run_track_visualization.py script. For example, run the following command from the src directory to start the visualization of recording 26, when the dataset is present in the data/ folder.

python3 run_track_visualization.py --dataset exid --recording 26 

All available options are listed in the following table:

Command-line Options	Default value	Description
--help	-	Show this help message.
--dataset_dir	"../data/"	Path to directory that contains the dataset csv files.
--dataset	exid	Name of the dataset (ind, round, exid, unid). Needed to apply dataset specific visualization adjustments.
--recording	26	Name of the recording given by a number with a leading zero.
--playback_speed	4	During playback, only consider every nth frame.
--suppress_track_window	False	Do not show the track window when clicking on a track. Only surrounding vehicle colors are displayed.
--show_bounding_box	False	Plot the rotated bounding boxes of all vehicles. Please note, that for vulnerable road users, no bounding box is given.
--show_orientation	False	Indicate the orientation of all vehicles by triangles.
--show_trajectory	False	Show the trajectory up to the current frame for every track.
--show_future_trajectory	False	Show the remaining trajectory for every track.
--annotate_track_id	False	Annotate every track by its id.
--annotate_class	False	Annotate every track by its class label.
--annotate_speed	False	Annotate every track by its current speed.
--annotate_orientation	False	Annotate every track by its current orientation.
--annotate_age	False	Annotate every track by its current age.
--show_maximized	False	Show the track Visualizer maximized. Might affect performance.

Please note that drawing additional features may decrease the playback animation update rate.
