OptiTrack
OptiTrack builds the world’s most accurate and easy to use wide area VR trackers – by optimizing the performance metrics that matter most for Virtual Reality tracking. The result is ultra-low latency, butter smooth tracking for any Head Mounted Display (HMD) or Cave automatic immersive environment.
OptiTrack Active
The perfect blend of OptiTrack’s world leading tracking precision and low system latency, now with the benefits of active LED marker identification. Track areas of 100ʹ × 100ʹ (30 m × 30 m) and more, with Slim 13E—the lowest cost, highest performing VR tracking cameras available today.
One “SKU” for HMDs, weapons and objects.
Track any object type using a single infrared LED marker configuration. This allows for hundreds of identically manufactured HMDs, weapons, controllers, and scene elements to be tracked simultaneously within the volume.
What do I get with OptiTrack Active?
LED Controller
Small, matchbox sized PCB controlling eight LEDs – use one for each object to be tracked. Flush mount 5/3 mm through hole LEDs that are black in color (or optional clear) and emit a wide angle invisible IR pulse seen by Slim 13e or other OptiTrack cameras.
Base Station
Typically installed at the center of the tracking area, the base station keeps the LEDs synced with the OptiTrack cameras.
Slim 13E Cameras
OptiTrack’s 1.3 MP, 240 FPS freeze frame tracking camera that delivers smooth, artifact free tracking for OptiTrack Active enabled devices.
OptiTrack Passive
The workhorse of motion tracking for over 20 years with a host of benefits for most applications. OptiTrack’s precision passive tracking provides fast, easy setup by placing low-mass reflective markers on the tracked person or object. This keeps all the technology with the cameras and not on the subject(s). That makes passive the most versatile approach for research VR, ground truth systems and out-of-home experiences with just one or two sites. The benefits of OptiTrack Active take over with larger scale installations. Active only requires development of one version of the HMD, weapons and other objects. Passive tracking requires that each object tracked has a spatially different marker cluster, so each object must be unique. For VR deployments which benefit from a single SKU manufacturing, OptiTrack Active is the preferred solution.
Exceptional 3D precision and accuracy
In order to reproduce convincing stereo images from the viewer’s POV, there can be no jitter, noise, or other artefacts from the tracking system. Motive:Tracker software, combined with our Prime Series cameras and Micron Series calibration tools, produce the most reliable 3D data on the market—capable of sub-20 µm accuracy in optimal conditions. For VR, this means smooth, artifact free tracking for the most compelling immersive experiences available.
High-speed, low-latency tracking
From high-speed cameras featuring image-stopping global shutters and fast-discharge LEDs, to a pipeline that processes data from photon to rigid body solve, OptiTrack has been engineered to track interactions with imperceptible latency.
