Embedded Stereo Vision for Mobile and Networked Devices
A new technology brings Linux-based stereo vision to various devices.
"DeepSea G2 Stereo Vision System consists of multi-purpose, embedded stereo camera that can be deployed in commercial and defense robots, automobiles, or networked together into person-tracking security systems. It integrates 2 CMOS imagers, stereo image processing ASIC, and FPGA implementing vision primitives with DSP/co-processor and embedded PowerPC running Linux. System transforms incoming image data into 3D object maps."

DARPA Challenge Gets Unmanned Vehicles to Steer Through Traffic
Following some previous stories on the DARPA Challenge and autonomously-controlled vehicles I would like to pass on this new CNN article. It speaks of yet another similar challenge that takes it up a notch.
"The robotic vehicles will have to navigate a complex 60-mile test course designed like a real city street filled with moving manned and unmanned vehicles. Participants will be tested on how well they make sharp turns, navigate traffic circles and avoid obstacles such as utility poles, trees and parked cars. The vehicles will also have to obey traffic laws, change lanes, merge with moving cars and pull into a parking lot using only their computer brain and sensors."
The vision (pardon the pun) of vehicles which drive themselves seems to be nearing reality.

Automobiles Perceive 3-D
There is work over at Honda on spatial analysis for cars.
Honda believes Canesta's chips could help drivers know how close they are to other parked cars, pedestrians, and get other similar, useful information. Automakers are also examining ultrasonics (sound waves) or stereoscopic technologies to give drivers better information about their surroundings.
This is by no means unprecedented as an application or concept, but it appears to gain popularity among manufacturers that don't focus on high-end vehicles.

More Computer Vision Applications from Google
Fascination with 3-D datasets for programs such as Google Earth is nothing new. And shortly after Google's acquisition and entry into computer vision I found the following dou:

Autonomous Vehicle in Rough Terrain
DARPA Grand Challenge at Cornell University concentrates on an application of computer vision. A
vehicle needs to be able to drive 175 miles of rough terrain without any human involvement. The prize for some happy winners to be endowed stands at $2 million.
From the full article:
"The vehicle navigates using an on-board Global Positioning System (GPS) unit accurate to within 10 centimeters, inertial and attitude sensors, stereoscopic vision and three LIDAR (light detection and ranging) sensors. They all feed into an elaborate artificial intelligence (AI) decision system that creates a small map of the immediate area around the vehicle, decides what path to follow and relays commands to controllers operating the engine, transmission and brakes..."
DARPA, by the way, is the same initiative that played a major role in spawning of the Internet.
