Starter Kit – Raspberry Pi 5 (GenX320) - Sensor Configuration

The driver of the Starter Kit for Raspberry Pi 5 allows to adjust the following sensor settings:
  1. Sensor biases for tuning the sensor for different application requirements and conditions,
  2. ROI (Region Of Interest) used for focusing on a part of the scene and reducing the amount of events

Sensor biases settings

There are several ways for adjusting the sensor biases settings:
  1. using OpenEB / Metavision SDK tools with a .bias or .json configuration file as described in the SDK documentation, for example 
    1. metavision_viewer -b custom.bias
  2. using OpenEB / Metavision SDK API as described in the SDK documentation
  3. using v4l2-ctl tool, for example
    1. setting a bias value
      1. v4l2-ctl -d /dev/v4l-subdev2 --set-ctrl bias_diff_on=24
    2. getting a bias value:
      1. v4l2-ctl -d /dev/v4l-subdev2 --get-ctrl bias_diff_on
We provide biases pre-sets for common applications that could be used as a starting point for bias tuning.

ROI configuration 

There are several ways for adjusting the ROI:
  1. using OpenEB / Metavision SDK tools with a .json configuration file, for example
    1. metavision_viewer -j config.json
  2. using OpenEB / Metavision SDK tools with a command-line option "-r", for example
    1. metavision_viewer -r x y width height
  3. using Metavision/OpenEB API such as Metavision::I_ROI facility
