Calculate object position by 2d markers
WebMar 15, 2024 · 2D Video Analysis. Biomechanical investigations – many people think of laboratories equipped with marker-based camera systems from Qualisys or Vicon that can record movements in three dimensions. However, 2D video analysis is often completely sufficient. This saves time and, above all, money. WebStep 2: Determine the position of the objects by creating a plane for the objects to sit on that has an x-axis and a y-axis and gives each object coordinates within the plane.
