Focus Robotics a New Hampshire based company has announced the nDepth vision processor which can handle 60 752x480 frames per second. The hardware-based solution uses Xilinx FPGAs to do depth processing. Curiously for a company which provides imaging products, there are no images from or of the product on their website.
Picture at right is not the nDepth system but Bob Mottram's Rodney, which uses his Sentience software to generate depth maps. Quite nice work. He kindly provides the source and documentation for the project. If you're impressed, please give him a job.
Point Grey Research provides a number of hardware based systems called Bumblebee, Digiclops, and Triclops and has been doing so for a number of years.
