Last Updated on December 13, 2022 by pg@petergamma.org

Exciting project based on instructions from Jonathan Savage (fellrnr.com), which is is relatively easy to do:

High quality camera for Kinovea recording:

  • People use USB 3 Balser cameras which costs up to 350 USD with Kinovea, see in the Kinovea forum.

Kinovea can be controlled from other applications

  • While Kinovea is running it is possible to send it commands from a third party application or script. For example this can be used to trigger recording based on a software event.
  • The commands use the Windows messaging system and the WM_COPYDATA message:

  • It is highly desirable to have a real-time calibration of a treadmill based for instance on this suggestion to have a high precision calibration, which eventually can be connected to Home Assistant to control a treadmill based on this calibration sensor automatically.
