You're in luck - we're working on it. We've had alpha level success in extracting depth data thus far. https://github.com/OpenKinect/libfreenect2 We're always looking for more contributors!

From the iFixit teardown: http://www.ifixit.com/Teardown/Project+Tango+Teardown/23835 Tango has a Primesense structured light system, a structure-from-motion coprocessor (or two) and a special depth sensing rear c

The newest ways of thinking about schools as learning communities have moved from the "pyramid of intervention" or how to save failing students, to a more holistic "diamond" that covers both ends of the spectrum. While n

This is the exact opposite of what I want in C++. The use of characters to clearly delineate code sections and scope is a strong benefit of C++ over these other languages. They're not a "source of errors" - they allow a comp

You cannot do better than our eyes. The dynamic range of eyes plus the bit depth are unparalleled in any camera. We're also backed by a very strong pattern matching algorithm. That said, stereo runs pretty damn fast these days. On A

All of those things? Plus the new StreetView cars are running LIDAR as well. Major projects like this have a ton of hardware limitations.

Google's system is not yet arbitrary. They prerun the roads the system drives on. I'm excited to see more "in the wild" units - more competition and innovation is always a good thing.

Google currently has a req out for a electromechanical engineer to work on a new sensor system. I'm betting they're building a new sensor for their vehicle - rotating, but perhaps not LIDAR. Cracking the heavy rain/snow prob

This is impressive! I worked on a project much like this for a client last year. We actually hid a camera behind the glass and could take "mirror selfies". It's a pretty simple add-on if you're making an interactive in

I'm a huge fan of my Sony MDR-V6's - I'd love to do a comparison test between the V6's and the 7506's some time. How do audiophiles get a chance to do this? I've never seen a "headphone store" on a s

There are some cheaper ones now - the K4W2 is a flash LIDAR. But range is always difficult. I think PMD is in use in BMWs. They purport a 90 meter(!) range, but I've never played with one.

Of course. Filters do wonders - but they're still not a panacea. You also get the covariance across that filter. Which means you still need to decide how much to cut, whether or not to reject as rain, dust or a reflection, whether to

Less that perceive the depth (2 inches at 50 meters is tough, especially from above) but that we're really good at pattern matching (vague square thing in the road? likely not road). You can think of parallax as stereo vision repeated

Well, LIDAR doesn't have that differentiation problem - it has a resolution problem for small (sub half meter) things at range. Stereo LIDAR would just add more points - you can correlate the two, but you'll still have resolution

You're discounting the actuation time for the machine, as well as latency in the system. Nothing is instantaneous. I've seen driving systems with 1-2 second latency from sensor data in to actuate brakes.

I've done a lot of work with perception systems and sensors. GP is right on the money with the problems. Rain is even difficult. Snow is the worst though - it is both wet and super reflective. Super reflective dazzles your laser&#x

This is exactly how it works - testing reveals corner cases and you address them.

by Qworg 13y ago
Certainly. LIDAR resolution is related to a few things: - How many beams you're putting out and at what angles - How fast you're spinning and how fast you can get the data back. - How many points of data you can get through your

LIDARs are not better sensors than our eyes. They are different, but not better. The human eye is an amazing instrument. Contrast range of 24 stops vs. 16 in a top of the line camera. (Think 24 bit ADC vs. 16 bit). Follow that up with 24

Debris is a really hard problem and I don't think they can get that resolution out of their LIDAR. Camera data may serve better, but that's hit or miss. I'd call this one unsolved. (Source: I'm a robotics/perception

They are using Ultra Ever Dry. It is not transparent.

Even better, they didn't actually develop anything. Ultra Ever Dry ( http://dry.technology/index.html ) has been around for a while now. It is pretty remarkable. The only downside is that it needs to be reapplied (and i

Using a system like this really helps for complicated and/or important code. All of our safety critical and embedded code references a checklist before it is made into a pull request. It really helps catch all of the "rubber ducky

"Driverless" tractors have been around for quite a while. Most large ag operations have very little human input when they're planting and harvesting.

I think this is overstated. Truck crops are certainly difficult, but row crops are mostly solved. Automatic berry picking for "tree type" bushes is a reality as well.
