"I found another link to this same rangefinder and one of the responses on it indicated good results using a TAOS now AMS linear array sensor which should actually be a lot easier and faster to decode for the ranging function.
He was only using a 128…"

"Just a question really, I am planning on using one of the longest range sharp IR ranging sensors on a servo scanned base to permit low resolution adaptive scanned depth image construction.
The Sharp ranging sensor uses intensity of IR dot reflection…"

Geoffrey L. Barrows commented on Chris Anderson's blog post Primsense launching "pencil-sized" Kinect-like 3D sensor at CES"This would definitely be a game changer if the depth perception was provided on the device itself (unlike the Leap Motion if I am correct). If they can recognize gestures like in that video, the resolution would be adequate for obstacle detection…"

Recently I started the DC Hardware Startup meetup as a complement to the many Web 2.0-ish entrepreneur meetups in the DC area and elsewhere, and then reached out to the organizers of similar meetups around North America. Two are about a year old- the …

I was pleased to see a cool laser rangefinding project on Kickstarter- I hope this project gets fully funded (and I'm a backer). I've actually been experimenting myself with structured light and laser rangefinding using our ArduEye hardware and thought I'd share it…
Continue New ArduEye using Stonyman image sensor chips
Posted on February 25, 2012 at 2:25pm 7 Comments 5 Likes
Awhile ago we (Centeye) started ArduEye, a project to implement an open source programmable vision sensor built around the Arduino platform. The first ArduEye version used a simple Tam image sensor chip and a plastic lens attached directly to the chip. After…

I've been experimenting with using an Arduino-powered vision system to detect and locate point light sources in an environment. The hardware setup is an Arduino Duemilanove, a Centeye…
Continue Wide field 4D optical flow odometry using Arduino and Stonyman image sensor
Posted on December 16, 2011 at 9:39am 4 Comments 3 Likes
I've been working on a new version of our ArduEye using one of our "Stonyman" image sensor chips and decided to see if I can grab four dimensions of optical flow (X shift, Y shift, curl, and divergence) from a wide field of view. I wirebonded a Stonyman chip to a 1" square breakout board, and attached it to an Arduino Mega256 using a simple…

- Bhargav- Do you mean integrate them with your system or actually program the devices themselves?

Hi Geoffrey, yes we have had a project on bridge inspection using the Infotron drone. You can find a little more information about the project here:

Your work looks pretty interesting too... I will have to have a look over it when I find some free time...Best, Andrew
