Hello All,

I have a digital camera file with the following data in it:

Camera Name: " Rollei-72mm_new"

Camera Description: " Rollei-72mm_new"

 

Focal Length [mm]: 74.5700000

Principal Point:

        x0 [mm]: 0

        y0 [mm]: 0

 

Fiducial Coordinates:

        Number of Fiducials: 4

      ID X[mm]         Y[mm]

       1           30            0

       2          -30            0

       3            0           30

       4            0          -30

 

Radial Distortion Observations:

        Type: "Radial Distance"

        Number of Observations: 2

      ID Distance[mm]       Distortion[microns]

       1            0                1

       2            1                2

 

Radial Lens Distortion Coefficients:

        k0: 0

        k1: 0

        k2: 0

 

Extended Parameters:

        Type: "NONE"

 

The all included data makes sense except the existence of the fiducials marks , As I now the fiducials are existed for farm cameras not for digital one.

 

Any Explanations please.

 

Best Regards,

Ahmad Saleh
