Canesta Equinox 3-D Sensor

Posted 10 Aug 2004 at 17:51 UTC by steve Share This

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 and EE Times articles.

Pricing, posted 11 Aug 2004 at 12:55 UTC by bitspit » (Observer)

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.

Promising, but too expensive for the mass market, posted 11 Aug 2004 at 19:07 UTC by motters » (Master)

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".

A couple of stats..., posted 11 Aug 2004 at 20:33 UTC by tim.holt » (Journeyer)

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.
