“For our ECE536 final project, we have implemented real-time sobel edge detection. Traditionally, sobel edge detection is done on still images. This project uses a 2MP camera to continuously capture an image stream, and sobel edge detection is performed real-time on an FPGA and displayed to a VGA monitor. Our motivation arose from our interest in computer vision and digital image processing.”

“The AVRcam is a small, real-time image processing engine capable of tracking colorful objects. The system was specifically designed to provide hobbyists with a vision system that can be easily added to their projects (robot, security, monitoring, etc).”

“For our project, we wanted to push the video sampling and processing capabilities of the ATmega644 8-bit microcontroller. Using a high-speed analog-to-digital converter as an input device, we were able to sample a reasonably high-resolution grayscale image from a color camera’s video output. Using this grayscale image, we are able to track objects and recognize shapes that stood out from the background by a customizable threshold.”

“Turn an old digital camera into a time lapse camera using an arduino, a relay, and an open source software program called makeAVI (windows). To modify the camera I disassembled the camera cover and removed the button that activates the shutter.”

“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.
