RealSense uses projected IR and thus doesn't work outdoors. (edit: because short-range and little ambient IR are required)

- agumonkey 12y agoThanks for the tip. Are there any portable technology that would work outdoors ?
- robotresearcher 12y agoVision works for animals, and a lot of people are working very hard to do it for computers. Google "UAV visual SLAM" for examples. LIDAR works already but is heavy, power hungry and expensive. Not good for these small vehicles.
- agumonkey 12y agoYeah, I pictures a Google Drone laughing.
- rasz_pl 12y agostereo vision, structure from motion, animals use both
- infogulch 12y agoExcept the end of that video shows it working in a forest... https://youtu.be/Us0BqJvsF9k?t=6m14s https://youtu.be/Us0BqJvsF9k?t=6m14s
- robotresearcher 12y agoOK, that's cool. I stand corrected. Clearly it can work outdoors in some circumstances. IR texture projectors get washed out by ambient IR from the sun. Thus the choice of a shady forest for the very nice demo. People have also used Kinect outdoors in the evening, etc. But in the general case you can't rely on this approach because sun.
- infogulch 12y ago> because sun. That's a fair point. So RealSense will probably work at night, in a shady forest (like the demo) or maybe the shady side of a mountain, but as soon as the sun is involved IR becomes unusable. I don't suppose you could switch the other side of the visible spectrum and do UV cameras, could you? Having your data reduced to one dimension per pixel really makes the AI easier.
- robotresearcher 12y agoThere's a lot of UV in sunlight too. Hence sunscreen. Many birds can see it. Some birds have patterns on them that are only visible in UV. Fun facts.
