AIMing for Automated Vehicles
The U.S. armed forces have had smart weapons for a long time now. It is just recently that they realized they need smart supply trucks. Hi, I am Paul F. Grayson, Team Leader of American Industrial Magic (AIM), one of last remaining teams of the 390 teams that worked on vehicles for the DARPA Grand Challenge series of unmanned vehicle races. AIM is working to save soldiers lives by searching for ways to make driverless Army supply trucks affordable. AIM is funded by donations from individuals like you who want to speed up the fielding of this life-saving technology. With this blog, you can look over my shoulder while I and my team work on this important technology. You will get a chance to look into the world of unmanned robotic vehicles, see some of the things that I see, and puzzle over the challenges of making vehicles driverless. Welcome to my world!
Raytrix uEye light-field option: 3D captured with one camera
November 10, 2010
For those of us who need eyes for our robots, being able to extract "range to object" information from pictures is a challenge that usually requires at least two of everything to create "right" and "left" images. Being able to get range information from a picture with half the amount of equipment would be a big savings. A message I got from uEye says they can do it all with one camera. Try it out and let me and the readers here know what you think of it.
Look for the models of the uEye camera that have the 4D light-field option. See www.ids-imaging.com.
This is technology developed by Raytrix GmbH www.raytrix.de that allows the generation of real 3D images with just one camera and a single lens. The trick that makes this possible is a modified sensor that allows these uEye cameras capture depth information, making the need for structured light obsolete. (See a Raytrix flash demo of what the camera sees: http://www.raytrix.de/index.php/id-3d-demo-235.html.)
Besides delivering 3D information from a single image, the Raytrix software also offers the option of altering the picture’s depth of field after capture. With this feature you can focus on other areas of an image, or even stretch the depth of field to cover the whole image area. The light-field cameras deliver up to six times more depth of field.
Applications such as traffic control will benefit greatly from this technology.
uEye light-field cameras are offered with either USB or GigE interface in resolutions of VGA, 1 or 2 Megapixel and frame rates of up to 60 fps. The cameras come with a software that generates stereo images for devices using 3D shutter glasses or polarization technology. In addition, the software package contains an API for programming the camera and processing the images.
