How to start

To start the sample, plug your camera and run:

python metavision_simple_recorder.py

When you quit the program (by pressing Q or ESC key), a RAW file is saved in your local folder or in the folder you specified with the option -o. You can then visualize this file using any of our viewer, for example the metavision_simple_viewer.py.

Note

If you use this sample to record data, you should perform some checks and configuration to optimize the quality of the data you will collect. Please refer to the section Recording from live camera from Metavision Studio page where we mention camera installation, lighting conditions, focus adjustment and multiple camera settings (biases, ROI, Anti-Flicker etc.).
