AdvancedAn American optical motion-capture brand that robotics labs use to measure ground truth.
OptiTrack is an optical motion-capture brand owned by the American company NaturalPoint, headquartered in Corvallis, Oregon. The company's early products were head-tracking devices such as SmartNav and TrackIR, before it developed multi-camera motion-capture systems: infrared cameras mounted around a capture volume (such as its PrimeX series) track reflective markers attached to a person or object, and the Motive software computes sub-millimeter position and orientation in real time. In embodied AI it is mainly used to provide high-precision ground-truth pose — a measurement treated as the correct answer — for robots, drones, or objects, and also to record human motion that is later retargeted onto humanoid robots. Along with Vicon, it is one of the two optical motion-capture systems most commonly found in robotics labs.
ExampleIn quadruped or drone experiments, researchers treat the body pose measured by OptiTrack as ground truth to evaluate a state-estimation algorithm's error.
