I'm trying to detect obstacles for a distance of up to 10 meters in an outdoor environment. Up to meaning that I also want to be able to detect obstacles that are close to the robot. I am thinking of doing this using stereo vision, but I am unsure if this is in fact even possible (before I buy expensive hardware). So is it possible? Has anyone had any success?
If this isn't possible, then what kind of sensors could give me a decent point cloud for such a range (outdoors)? I need a sensor that will fit a medium size robot. Also it needs to be not overly expensive since I have a limited budget.
