PC/104+ nDepth™ Vision System
PCI nDepth™ Vision System
Overview
Focus Robotics nDepth™ PCI vision system is for companies and individuals
looking to add real-time depth perception to an existing PC platform.
Operating at 30 frames per second for 752x480 images, the PCI nDepth" vision system
provides outstanding depth performance for demanding applications
such as mobile robot navigation, people tracking, gesture
recognition, targeting, 3D surface visualization and advanced human
computer interaction. Customers looking for tighter integration or IP cores should
visit our Stereo Vision Cores page.
nDepth™ Processor via PCI
At the center of the system is our 2 billion pixel disparities per second
nDepth™ vision processor.
This programmable hardware device (FPGA) handles all aspects of depth calculation,
including realtime lens undistortion, camera rectification, correspondence searching,
and advanced post filtering for error removal. And unlike software based depth
perception, the nDepth™ processor uses virtually no PC CPU resources
so your PC is free for higher level tasks. All output from the processor is
sent via direct memory access (DMA) to the PC. The undistorted and rectified
(calibrated) images, along with the depth image, can also be sent every frame
if desired. Our use of programmable hardware allows for upgrades and expansion
so you know you can always have the most advanced solution
6cm Baseline Stereo Vision Camera
The PCI nDepth™ vision system includes a 6cm 752x480
stereo vision camera. Available with an automotive quality monochrome image sensor,
the Focus Robotics stereo vision camera boasts >60dB of dynamic range and near IR
enhanced performance for use with non-visible near IR illumination. Support for
M12x0.5 uVideo lenses ensures you get the right optics for your applications needs.
The stereo camera connects easily to the PCI card using one standard CAT6 cable up
to 5 meters in length. The cable carries all necessary power, data, and control for
the stereo camera. With progressive scan, global shutter and low-noise imaging
technology, this stereo camera is ideal for a wide variety of imaging
applications in real-world environments.
