Technology Benefits


Focus Robotics nDepth™ stereo vision processor is an excellent
solution for adding low cost, real-time depth perception to new and existing
products. With integrated depth perception, products can interact with and
monitor the environment in ways more similar to humans. Using our stereo cores in
an FPGA or ASIC along with and a pair of standard camera sensors, products get the
depth information needed to measure objects, track objects, and even avoid objects
in real-time. Examples of applications include mobile robot navigation, people tracking,
gesture recognition, targeting, 3D surface visualization, immersive and interactive
gaming, and more.


Many other means of gathering depth information fail to be practical.
A laser range finder's price of seven to ten thousand dollars, for example, is too
expensive for many products. Complex systems of mechanical mirrors and servos are then
needed in order to cover an entire area. Likewise, even the very best software
stereo system yields less then 3 frames per second on a 752x480 image even on a
dedicated 3GHz Pentium class processor. The power usage, size, and cost of a PC that only
provides 3 frames of depth is too high for many products. In contrast, with standard
camera sensors the nDepth™ stereo vision processor provides up to 1024x1024 pixels of
depth information at a rate of up to 30 frames per second all in a low cost, low power

Feature Rich

  • Up to 30 frames per second of 1024x1024 depth information provides superior
  • Good accuracy and error removal for a variety of scene conditions fosters
    a wide range of use.
  • Camera calibration, depth searching and error removal implemented in the processor
    lessens the demand on the host computer.
  • Hardware optimizations enable use of low cost, low power FPGAs such as the Xilinx
    Spartan3. No fan or heatsink is required.
  • Implementation in programmable hardware allows for future upgrades and expansion.
  • PCI and high speed serial ports provide both selection and standards for
    integrating with the processor.
  • Complete solid state design with no moving parts ensure ruggedness.
  • Optional sale as IP core allows integration in existing FPGA hardware or
    volume ASIC production.
