spryTrack 300
Compact & Mobile, data transmission via Bluetooth
Sub-millimetric precision 140 μm RMS up to 1.4 m
USB 3.0 type C complete access to images and data
Active and passive markers tracked simultaneously
The compact spryTrack 300 is composed of two cameras designed to acquire infrared camera images, as well as, to detect and track fiducials (reflective spheres, disks and/or IR-LEDs) with high precision.
Triangulation enables retrieving 3D position of each fiducial with sub-millimetric accuracy. When several fiducials are affixed to a marker, its pose (orientation and position) is calculated with 6 degrees of freedom.
The spryTrack 300 has the ability to provide 3D positions of fiducials and/or pose of markers, as well as retrieve structured-light images for dense 3D reconstruction.
The SDK allows access to data at different stages of processing, starting from raw images, individual 3D positions of fiducials, and up to the pose of markers. The SDK also provides multi-level fault checking. This makes it possible to access error information in real-time at any processing stage: fiducial occlusion level, stereo de-calibration, marker registration error and more.
The spryTrack offers a USB 3.0 Type C connection for power and data.
