Harinath replied to Geoffrey L. Barrows's discussion ArduEye odometry example using Tam2 (16x16) chip and Rox1 boardHello Everyone,This forum post is a temporary repository for software libraries, initial source code, and hardware files for the new ArduEye "Rocket" system, for Stonyman and Hawksbill image sensors.…Continue

OVERVIEW:This is a quick start set of instructions to demonstrate simple odometry using an "ArduEye" and a Tam2 (16x16) chip. Note that in order to view images or sense optical flow, you need a lens…Continue

I am interested in using monochrome cameras for multi-spectral imaging experimentation. Its easy to find USB cameras with a Bayer filter but I need sensors without any filtering. Is there a source…Continue

The ArduEye prototype (left) and the finished sensor (right)
In a previous post, I demonstrated that the ArduEye platform could be used to prototype a…

In a recent post we showed off a new ArduEye system using a Stonyman vision chip. A batch of 200 Stonyman breakout boards is (still) being fabricated. But in the mean time we decided to…

As a participant in the Harvard University Robobees Project, our primary task at Centeye is to develop a vision sensor system that will fit into a small flying robot about 2cm in size. The target weight budget for the vision system is 25 milligrams. While we still have a ways to go before achieving this, we…

Awhile ago we (Centeye) started ArduEye, a project to implement an open source programmable vision sensorbuilt 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 much…

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…

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 connecting…

This device is no match for an optical flow sensor made using an optical mouse, but it does (minimally) work. Think of this little project as a fun hack more than anything else.
This optical flow sensor uses CdS cells as light sensing…

As part of Centeye's participation in the NSF-funded Harvard University Robobee project, we are trying to see just how small we can make a vision system that can control a small flying vehicle. For the Robobee project our weight budget will be on the order of 25 milligrams.…

In an earlier post, I shared plans for a CYE32 vision sensor based around the AT32UC3B1256 microcontroller. After working with this vision sensor for a couple months, it has become a useful platform for trying out new vision chips and new image processing algorithms.
I put together a short…
