Depth perception is crucial to our ability to navigate a three-dimensional world. It's important for robots, too. Here we see the SVS, or Stereo Vision System, a stereoscopic video platform for robot navigation and surveillance.

The data from two separate video cameras are combined to form 3-D images, or anaglyphs, that can be viewed with red-and-cyan glasses. The system is shown mounted on a YARB (Yet Another Robot Blimp).
