This project is part of the ECE597 32-bit Embedded Linux class at Rose-Hulman Institute of Technology in Terre Haute, IN.

Project Goal

The goal of this project is to implement a simple game of "Pong" on the Beagle Board that allows a user to play the game by gesturing with their hands rather than using a mouse or keyboard.

OpenCV

/*Get the color of the hand, so that we can track the movement of the hand automatically.*/ void loadTemplateImage() { IplImage *tempimage = cvLoadImage("/home/dica/workspace/cvex1/sshou.bmp",1); cvCvtColor( tempimage, hsv, CV_BGR2HSV ); int _vmin = vmin, _vmax = vmax;

cvInRangeS( hsv, cvScalar(0,smin,MIN(_vmin,_vmax),0), cvScalar(180,256,MAX(_vmin,_vmax),0), mask );

cvSplit( hsv, hue, 0, 0, 0 );

selection.x = 1; selection.y = 1; selection.width = 320-1; selection.height= 240-1;

cvSetImageROI( hue, selection ); cvSetImageROI( mask, selection ); cvCalcHist( &hue, hist, 0, mask );

float max_val = 0.f;

cvGetMinMaxHistValue( hist, 0, &max_val, 0, 0 ); cvConvertScale( hist->bins, hist->bins, max_val ? 255. / max_val : 0., 0 ); cvResetImageROI( hue ); cvResetImageROI( mask ); track_window = selection; track_object = 1;


cvZero( histimg ); int bin_w = histimg->width / hdims; for(int i = 0; i < hdims; i++ ) { int val = cvRound( cvGetReal1D(hist->bins,i)*histimg->height/255 ); CvScalar color = hsv2rgb(i*180.f/hdims); cvRectangle( histimg, cvPoint(i*bin_w,histimg->height), cvPoint((i+1)*bin_w,histimg->height - val), color, -1, 8, 0 ); }

cvReleaseImage(&tempimage);

}

Task List

Below is an estimated list of tasks to complete Task list will be updated as necessary

Task Status Description
Pong on the Beagle Board Complete Port a simple game of classic pong onto the Beagle Board with keyboard/mouse input
Webcam interface with the Beagle Board and OpenCV Complete Get the Beagle Board to recognize the webcam and perform basic functionalities from OpenCV (connect to camera, snapshot, etc.)
Refactor Pong Complete Refactor Pong to work with a different input (camera)
Track hands with camera and OpenCV Complete Track user's hands using OpenCV library functions on the Beagle Board
Interface tracking camera with pong Complete Join the tracking and game into one system such that users can play pong with their hands
