The system is ideal for use in environments with changing lighting conditions and for unknown objects. Passive sensing The system does not require emission of any signals. Therefore, it allows use of multiple systems without interference. Calibrated Optical distortions and misalignments of the cameras are compensated for in the software. The unit weighs 450g and its dimensions are 14 x 14 x 4cm.
Stereo vision correlates features between images in order to determine range.
Three cameras greatly improve quality over traditional two camera stereo. Applications 3D Tracking - people tracking.
