Interoperability Sample using Python

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

The following formats are supported:

• rosbag

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

• aedat4

The source code of this sample can be found in <install-prefix>/share/metavision/sdk/core/python_samples/metavision_interop when installing Metavision SDK from installer or packages. For other deployment methods, check the page Path of Samples.

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
