fusionTrack 500

Real-time  high-speed 335 Hz and low latency 4 ms
High-precision  90 μm RMS up to 2 m
Ethernet connection  for both data and power (PoE+)
Open system  complete access to images and data
Active and passive markers  tracked simultaneously

The fusionTrack 500 is a passive and active, real-time optical pose-tracking system specially designed to detect and track reflective spheres, disks and IR-LEDs in real-time video streams. The fusionTrack is composed of two cameras that observe reflective and/or active fiducials (IR LEDs) simultaneously, and it uses triangulation to calculate their locations with unrivalled precision and with an unparalleled non-interpolated measurement rate of 335 Hz. When several fiducials  are affixed to a marker, the system can determine its pose (position and orientation) with 6 degrees of freedom (x,y,z,α,β,γ).

The fusionTrack SDK enables access to data  in real-time at different stages of processing, including raw images, individual 3D positions of fiducials (reflective spheres and disks / IR-LEDs) and up to the pose of markers. The SDK also provides multi-level fault checking. It allows access to error information in real-time at any processing stage: fiducial occlusion level, stereo de-calibration, marker registration error and more.

The fusionTrack can be customized to fit your requirements (e.g. precision level, acquisition speed, working volume, extensions). Moreover, the system is compatible with existing passive image-guided surgical tools that are widely used in the medical field. With its unparalleled measurement speed, accuracy and latency, the fusionTrack 500 is ideally suited for robotic applications.
