Virtual measurements

lundi 26 novembre 2012.

You can find here Examples and demos about measurement of vibration using KLT motion tracking algorithm (OpenCV)

  • Previous Examples here
  • J. Morlier, G. Michon, Virtual Vibration Measurement Using KLT Motion Tracking Algorithm, J. Dyn. Sys., Meas., Control — January 2010 — Volume 132, Issue 1, 011003 (8 pages) doi:10.1115/1.4000070

Demos from ZIP file containing :

Zip - 48.7 Mo
  • Mode1low.AVI – 3.7 Mo : Experimental video data
  • datamode1.txt – 51.2 ko : Results from KLT trackers
  • out.avi – 51.4 Mo : Output video of the KLT algorithm
  • lkdemoresonance2.cpp : KLT algorithm
  • testmode1.m : matlab code to extract trackers signals

Using Ch/OpenCV just launch the lkdemoresonance2.cpp then

Hot keys :

  • ESC - quit the program
  • r - auto-initialize tracking
  • c - delete all the points
  • n - switch the \"night\" mode on/off
  • Left click (To add/remove a feature point click )
  • Right click (run KLT)
