Nicole Stodola, Chris Pederson and Gerry Finlay Curling Coach Nicole Stodola, Chris Pederson and Gerry Finlay Group 15

Project Motivation Between Chris and Nicole we have 40+ years of curling experience Most important aspect of a curling delivery is level shoulders Improvement to the standard way of delivery verification

System Block Diagram System Startup Mode Selection Analyze Mode Save Mode Review Mode Video is Analyzed as curler delivers Video is saved to SD card Video is retrieved from SD card and analyzed

Code - Image Processing Algorithm Prototype for(int i = 0; i < img.getWidth(); i++){ for(int j = 0; j < img.getHeight(); j++){ rgb = getPixelData(img, i, j); int t = rgb[2] + rgb[1] + rgb[0]; if ((t/3 < 100 && rgb[2] > 100) || (t/3 < 150 && rgb[2] > 150 )){ Color w = new Color(255,255,0); img.setRGB(i,j, w.getRGB()); }

Image Processing: Before and After

Challenges Features to Add or Remove Target tracking and identification Controlling mode selection through software Saving video into memory Features to Add or Remove Remove Touch Screen replaced with 4 push buttons Removing Save and Review modes Add More sensors to track additional body parts Play video on LCD touch screen

Test Plan VHDL testing C Testing System Testing Test each module separately Testbenches for all VHDL C Testing Unit testing Framework System Testing Test with a competitive curler Edge cases Different slides Obscure target
