Stereo-vision for Planetary Robots

Posted 10 Jun 2003 at 20:27 UTC by steve Share This

With all the robots headed for Mars lately, this seems like timely news. From a recent issue of a Springer-Verlag technical journal comes this paper, entitled A stereo-vision system for support of planetary surface exploration, that describes a vision system developed for the ESA. The system uses a variety of algorithms to process images from stereo vision sensors and create a 3D terrain map. The system is self-calibrating to allow for the stresses likely to occur during an extended space voyage. The self-calibration algorithm is based on epipolar geometry. A demo of how it works can be found on the VISICS website in Belgium.

Looks cool. I think those robots have about three pairs of stereo cameras, some for navigation and others for science experiments.

I'll be interested to see how well they fare on the martian surface. It will be the first time I've see a robot navigate by sight alone.

If the stereo works well there could be spin-off applications for other ground based autonomous rovers.
