ECE497 Project Set Playing Beagle
The game Set uses a 3 x 4 grid of 12 cards that have different symbols on them. These symbols differ in shape, fill, and number. The goal is to find a set of three cards. See here for Set game instructions.
Using the BeagleBoard, we have developed a system that uses a webcam to take a picture of the cards in play and uses OpenCV and Python to find the sets from the picture.
Our system correctly identifies all of the sets in the hand that the image recognition provides.
It can run completely on the Beagleboard and processes aproximately 1 frame per second.
Currently, the image recognition is the downfall to our success. The image recognition does not find the correct symbols on the cards, and so the rest of the system does not find the correct sets.
The sets that are found are correct for the found cards, but not the actual cards in play.
Our system is almost functional, but there are still some problems that need to be overcome. The image recognition is the biggest hurdle that we need to overcome and after that is completed, the system will work correctly.
Give step by step instructions on how to install your project on the SPEd2 image.
- First clone our github repository: firstname.lastname@example.org:mayhewsw/BeagleSetGame.git
git clone email@example.com:mayhewsw/BeagleSetGame.git
- Install python-opencv
$ opkg install python-opencv
- You will also need a webcam and a way to mount it. We used a Sony Playstation Eye, but any webcam with at least 640x480 resolution should work. Our mount held the camera about 7 inches above the playing surface, and had it pointing straight down.
Once everything is installed, how do you use the program? Give details here, so if you have a long user manual, link to it here.
- First, run the autogain executable. If you are using the SPEd2 Angstrom image, then this executable is found the root directory.
- Next, run trackbartest.py. When this runs, it opens up 2 images. One of the images is streaming live from the webcam, and it has slider bars that set the properties for the camera. The other image is a reference image. Slide the bars until the live image looks like the reference image.
Once you have found a configuration you like, press enter. This will save those values to a file called cameraConfig.cfg, which is read later. Exit the window by pressing Escape.
- Now you can run the actual program. Run runner.py.
