radar-scenes 1.0.4

Helper Package for the RadarScenes Dataset

RadarScenes Tools

About

This python package provides some helper scripts for the RadarScenes dataset.

Among others, the package contains a viewer for the radar data and camera images from the dataset.

Installation

The package is designed for Python versions >=3.9 and can be installed using pip. Installation using pip is the recommended method.

The alternative is to clone this repository and manually install the package using the setup.py.

Virtual Environment

It is highly recommended to install the package in its own virtual environment. To do so, create a virtual environment prior to installation of the package:

python3 -m venv ~/.virtualenvs/radar_scenes

This will create a python virtual environment called radar_scenes in the folder .virtualenvs in your home directory.

This environment can be activated via

source ~/.virtualenvs/radar_scenes/bin/activate

An active virtual environment is indicated by a preceding (radar_scenes) line before the usual bash prompt.

Once the virtual environment is active, the package can be installed with the command

pip install radar_scenes

You do not have to clone this repository for the installation.

There are multiple guides available which give more information about virtual environments and installation of python packages, e.g. on python.org.

System wide installation

If no virtual environment is desired (again, this is discouraged!) , the package can be installed using the global version of pip

pip3 install --user radar_scenes

The flag --user can be omitted if a system wide installation is desired (may require root privileges).

Windows Setup Hints

When getting error message
"qt.qpa.plugin: Could not load the Qt platform plugin "windows" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem."
don't give up. Instead, you should try this:

• set an additional environment variable pointing to your anaconda plugins directory (e.g. set QT_PLUGIN_PATH=\Library\plugins)
• copy the right dlls into the directory above - hint taken from LINK:
  • copy the following files ...
    • \Anaconda3\Lib\site-packages\PySide2\plugins\platforms\qminimal.dll
    • \Anaconda3\Lib\site-packages\PySide2\plugins\platforms\qoffscreen.dll
    • \Anaconda3\Lib\site-packages\PySide2\plugins\platforms\qwindows.dll
      to:
    • \Anaconda3\Library\plugins\platforms

Usage

After successful installation, the radar_scenes package is available in your python environment.

Radar Data Viewer

During installation, the command rad_viewer is made available. If you have installed the package into a virtual environment, this command is only available while the virtual environment is active.

Calling rad_viewer launches the radar data viewer. As an optional command line argument, a path to a *.json file from the RadarScenes dataset can be provided. The sequence will then be loaded directly on start up.

Example:

(radar_scenes)
$ rad_viewer ~/datasets/radar_scenes/data/sequence_128/scenes.json

The time slider itself or the arrow keys on your keyboard can be used to scroll through the sequence.
