Canesta has announced a new 3-D
image sensor that could have applications in machine vision and
robotics. What's it do? According to Canesta, the Equinox chip
resolves a scene into pixels, as does an ordinary camera chip, but
instead of simply providing the brightness of each pixel, Equinox
additionally provides the distance from each picture element to the
sensor chip. On the downside, the device only provides a 64x64 pixel
image and only MS-based, proprietary development software is available
at present. Canesta claims it will be a "low-cost" sensor but there's no
word yet on a price. At present the sensor is only available as part of a development kit for
$7,500. For more
technical details, see the developement
platform data sheet (PDF format). You can also read more about the
sensor in CNET
7500$ and its only a low res cmos camera with a rangefinder?
Hint, buy 2 cmos board cams for 100$ and do stereo....
I see the value of this product, but with a a 7500$ pricetag, I doubt
many will find a home.
Looks good, but doesn't really explain how it calculates the distance to
objects. Presumably it is using a laser or projecting a pattern in a
non-visible part of the spectrum.
The price tag is way too high though, and it will only be used for
industrial vision systems in factories.

Yea but where do you get the software and all to do this? There's a lot
more to a vision system than "hint: get some cameras".
20 meters max distance with the 30 deg FOV version.
Supposedly works in outdoor (sunlight) conditions.
Uses an IR laser for illumination.
I'm really curious how this would do in a more rugid environment - like
on a DARPA vehicle.
I for one, think this is an amazing product. As a student studying
electrical engineering with a focus on machine intelligence, I can tell
you that operating two cameras in stereo has rather poor distance
detection even with the most advanced software (it relies more on edge
detection actually, to seperate objects). Sure, seven thousand dollars
is pricey, but this thing has only just hit the market. Plus that money
is for the entire development kit, not just the camera.
