Interoperability Sample using Python

The sample metavision_interop.py shows how to read multiple AER events file formats.

The following formats are supported:

• rosbag

• CSV files from the HDR dataset available at http://rpg.ifi.uzh.ch/E2VID.html

• aedat4

Expected Output

The sample visualizes CD events read in the input file:

Requirements

Some Python libraries have to be installed to read rosbag and aedat4 formats:

• to read rosbag file, you need to install the rospy library

  Linux

  python3 -m pip install --extra-index-url https://rospypi.github.io/simple/ rospy rosbag
  

  Windows

  python -m pip install --extra-index-url https://rospypi.github.io/simple/ rospy rosbag
  

• to read aedat4 file, you need to install the aedat library

  Linux

  python3 -m pip install aedat
  

  Windows

  python -m pip install aedat
  

How to start

To start the sample on a ZIP file containing a TXT file in CSV format downloaded from the High Speed and High Dynamic Range Video with an Event Camera Dataset page , provide the full path to the file:

Linux

python3 metavision_interop.py /path/to/gun_bullet_gnome.zip

Windows

python metavision_interop.py /path/to/gun_bullet_gnome.zip

To check for additional options:

Linux

python3 metavision_interop.py -h

Windows

python metavision_interop.py -h
