Markers

Qualisys offers various marker options for different motion capture applications.

Passive markers are tracked by reflecting the cameras’ infrared lights. The markers can be mounted on subjects’ skin or clothing with double-sided tape, screwed onto rigid clusters, or Velcroed onto mocap suits.

Active markers are battery-powered and emit their own light, making them easier to track in reflective or dusty environments. Active Traqrs also use sequential coding for automatic identification in QTM.
