“In this project we turned an Altera Cyclone II FGPA into a simple video production unit with the help of a Sony Handycam and a PC for serial communication. The main focus of the project is the ability to provide a green screen effect, most commonly seen with weather news. We would extract the green regions of the video based on a threshold and display a background image, such as a weather map.”

“The protocol is very simple between OpenCV and Arduino: the program transmits one integer per line through the serial connection (using the USB connection or a RS232 port). Each integers gives the position (in microseconds) to where the servo should move.”

“Photographers want total control of all aspects of a camera such as exposure, shutter speed and aperture size. However, some breathtaking pictures require the photographer to be separated from the camera, and thus there is a need for remote access and currently such commercial solutions are very limited.”

“How does it work? A digital camera is placed in phonographic rotational axes and records laser light reflections from object's surfaces (it works better in the dark). Distortion of laser line corresponding to object's deformations derive the location from the laser source. Constant rotational speed and precise measurment are very important.”

Getting streaming video or even a single snap shot picture out of a camera module is a challenging feat because so much happens so quickly. This article shows you one method for transferring JPEG snap shots from a camera module to your PC using a .NET interface. Things for this project are software heavy and light on the hardware.

Here's a rather novel creation, a DS-DSLR. A high quality camera controlled by a portable Nintendo DS game system. The article explains how it was done with some guidance for people wishing to do similar work. No source code from this project, but many pointers for doing your own DIY-DS work.

Infrared Cameras are great tools for working with electronics. They display heat graphically which gives away short circuits in mili-seconds and can telling you who is blushing. This project shows you how to build your own DIY thermocam for around $100. Given that IR cams cost $1000's, this is worth a look.

If you're interested in using a camera module in any of your projects, this project shows you how to connect an AVR to a camera and get it working. The sample code is posted and the schematic is basic. Luckily most camera modules operate the same so you'll be able to adapt the code if necessary.

Here's a more professional RPV robot from cannibal robotics. Although the source code is lacking, there's a lot of details about the robot and how it works. The multiple pictures of the robot tell the story of how it works and what is going on where.

Tele-presence robots are a new idea in DIY circles mostly because they're better put to use in offices. This project shows you how to turn a netbook into a tele-presence robot. People will see your face and body through a camera and you can act naturally as if you were actually there. Take a look at the build process, its pretty cool.
