The problem that I see with the real-sense is that just like the Kinect it&#x27;s based on structured light. This means that it will only work indoors (just like the Kinect). So their cool demo with putting that on a drone is kind of pointless, because who flies a drone indoors?<p>There are now some devices available which can provide depth data through passive stereo vision. I have recently seen this one in action: <a href="http:&#x2F;&#x2F;nerian.com&#x2F;products&#x2F;sp1-stereo-vision&#x2F;" rel="nofollow">http:&#x2F;&#x2F;nerian.com&#x2F;products&#x2F;sp1-stereo-vision&#x2F;</a><p>The problem with that, however, is that it is targeted at industrial market and probably way to expensive for any ordinary consumers. I guess we will still have to wait for some major revolution in depth sensing.
