Note

This Python sample has a corresponding C++ sample.

Time Surface Sample using Python

The sample metavision_time_surface.cpp shows how to use the algorithm MostRecentTimestampBuffer which is a Python binding of Metavision Core SDK to compute the Time Surface of the CD events and to display it using our SDK UI module.

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

Expected Output

The sample visualizes the Time Surface of events:

How to start

To start the sample based on the live stream from your camera, run:

python metavision_time_surface.py

To start the sample based on recorded data, provide the full path to an event file (here, we use the file spinner.raw from our Sample Recordings):

python metavision_time_surface.py -i spinner.raw
