Calibration Stuff

lecture notes camera calibration with regular pinhole camera model parameters.

example hand calculation of camera projection with homogenous coordinates in flat world (2D world, with 1D camera)

matlab code for calculating the camera parameters (in calibration.m)

   [U,S,V]=svd(B);
   m= V(:,12);

Epipolar geometry Stuff

Updated easier lab to save time in epipolar geometry lab

Code for making Q:

  ons=ones(NPOINTS,1);
  q1=[prhat(:,1) prhat(:,1) prhat(:,1) prhat(:,2) prhat(:,2) prhat(:,2) ons        ons        ons];
  q2=[plhat(:,1) plhat(:,2) ons        plhat(:,1) plhat(:,2) ons        plhat(:,1) plhat(:,2) ons];
  Q=q1.*q2;

some good points:
