What is Qualisys Track Manager (QTM)?

Qualisys Track Manager (QTM) is the central software platform for all Qualisys motion capture systems. Designed as a single-application hub, QTM handles everything from camera calibration and real-time data capture to trajectory editing, skeleton solving, and export — whether you are running a sports biomechanics lab, a clinical gait analysis unit, a drone tracking system, or a character animation studio.

QTM integrates directly with force plates, EMG systems, eye trackers, and a wide array of third-party devices, synchronizing all data streams into a single timeline for analysis and export.

Key Features

• Real-Time Skeleton Solving: QTM's inverse kinematics solver handles one or more actors simultaneously in real-time, tracking through occlusion and supporting demanding poses including crouching, wrestling, and floor-based movement.
• Automatic Marker Identification (AIM): The pre-trained AIM model automatically identifies markers from a T-pose, dramatically reducing setup time and eliminating manual labeling in most standard configurations.
• Extensive Device Integration: Natively synchronizes force plates, EMG, eye trackers, and other physiological sensors — all time-aligned with marker trajectories in one recording.
• QTM Scripting Interface: A built-in Python scripting environment enables custom automation, batch processing, and integration with external analysis pipelines directly inside QTM.
• Game Engine Plugins: Full-featured real-time plugins for Unity, Unreal Engine, iClone, MotionBuilder, and Maya, plus FBX export for broader animation and simulation tool compatibility.
• Passive and Active Marker Support: Compatible with both passive reflective and active LED markers, supporting legacy setups and specialized tracking applications.

FAQ

• Which Qualisys cameras does QTM support? QTM supports all Qualisys camera systems including Arqus, Miqus, Miqus Hybrid, Miqus Video, Arqus MRI, and the underwater series — all within the same software environment.
• What third-party devices can QTM synchronize with? QTM natively integrates with force plates, EMG systems, eye trackers, galvanic skin response monitors, and many other measurement devices via analog input, digital trigger, or dedicated API.
• Is QTM suitable for real-time applications? Yes. QTM streams real-time 3D marker data, rigid body poses, and skeleton data via its RT protocol, used by game engine plugins and custom applications via the SDK.
• Can QTM be scripted or automated? Yes. The built-in QTM Scripting Interface supports Python scripting for batch processing, custom workflows, and automated data export pipelines.
