fusionTrack 250
Real-time high-speed 120 Hz and low latency 4 ms
High-precision 90 μm RMS up to 1.4 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 250 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 120 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). Moreover, the system is compatible with existing passive image-guided surgical tools that are widely used in the medical field.
