  1. 2D/3D motionanalysis Martin Sebera sebera@fsps.muni.cz

  2. Idea • What to measure • Distance, time, speed, angles • Get source • Fromyoutube (howto download-http://www.clipconverter.cc/ • From web, TV, online source • Fromowncamera

  3. Deficiencies, errors, bad source • Qualityof video – • resolution 720x576, 640x480, no less, • 25 or 30 frames per second (fps), not less • Sceneistoo far • smallstature • large movements in the frame - http://atleti-tisnov.rajce.idnes.cz/2013-09-07-4.kolo_Uherske_Hradiste#MVI_3944.jpg

  4. Always… • fixed point • the measured distance • angle(camera-scene) - 90 degrees • VARIABLES are measuredlikethe ratio between the information on the video and in fact

  5. Distance in 2D/3D space Distance betweentwopoints • The Euclidean distance between two points of the plane • with Cartesian coordinates (x1, y1) and (x2, y2) is • In three-dimensionalspace, the distance betweenpoints(x1, y1,z1) and (x2, y2, z2)is

  6. Angles http://en.wikipedia.org/wiki/Triangle

  7. Project • Choose sport • Distance • Time • Speed • Angles
