The program


Results:

1. Condition Number





  • For the "corridor"



2. Average Errors (corresponding to Hartley's fig. 8)


  • For the "house"



  • For the "calibration_jig"



  • For the "corridor"




3.  Epipolars


  • For the "house" 
    • left image:   173.154    -8064.71
    • right image:  74.7648,   -3601.55
  • For the "calibration_jig"
    • left image:  1041.2  206.131
    • right image:  1035.56  206.44
  • For the "corridor"
    • left image:  256.427  184.601
    • right image:  255.68  183.693


4.  Epipolar lines (that overlay the images)


4.1 For the "house"
  • left image:




  • right image:






4.2.  For the "calibration_jig"

  • left image



  • right image






4.3. For the "corridor"

  • left image:


  • right image









5. Problem:

In the case of the "house", every time after running, I got noticeable results as in the epipolar, fundamental matrix, to some degree.   The other cases are stable.
