Project Overview

The goal of this project is to use the beagle board to run image recognition on a camera feed located inside a car, and then signaling to the driver via a pico projector various objects of interest.

  • Create Minimal Linux Image that can run OpenCV and run the display
  • Determine hardware needed for the project
  • Work on getting a camera functioning on the beagle board
  • OpenCV running nativly on beagle with min config
  • OpenCV working on video stream
  • Projector working on Beagle
  • Car integration (power)
  • Algorithm development

Installing OpenCV (Development Machine)

This is a script that will install OpenCV on a debian-based development machine. The script will add the debian testing repositories and install OpenCV and its dependencies. The repositories are then removed to avoid conflicts with existing packages during regular updates.


echo "deb testing main" > /tmp/opencv-temp.list 
echo "deb-src testing main" >> /tmp/opencv-temp.list
sudo mv /tmp/opencv-temp.list /etc/apt/sources.list.d/opencv-temp.list

sudo apt-get update
sudo apt-get install -y --allow-unauthenticated libcv4 libcv-dev libhighgui4 libhighgui-dev libcvaux4 libcvaux-dev

sudo rm -f /etc/apt/sources.list.d/opencv-temp.list

sudo apt-get update

Installing OpenCV on the Beagle

Add information from notes here.

OpenCV Haar Training

Display Buffer Mapping

Pico Projector Integration

As of revision C4 of the Beagleboard there is no necessary configuration needed to display native resolution on the projector.

Future Directions

GStreamer on the DSP

There is a package available for the beagle called gst-dsp, which is a native GStreamer plug-in to give it access to the DSP. Along with gst-opamfb and the dsp-bridge driver, this should allow us to access the DSP directly and output video directly to the framebuffer. OpenCV can interact with GStreamer, so this appears to be a very promising direction for the project. See this article for more information and a demonstration. That article also has a link to a minimal beagle image that provides a native framebuffer video player without requiring X.
