When you use Tapas, a important part of informations are displaying directly in the terminal window, like image resiual or number of tie points used per images. Don't forget to look at this residuals when you use Tapas, for a good orientation you can decrease under 0.5px. All this informations are stocked in a file named "Residual.xml"

Workflow

Tapas process internal and relative orientation, you it's placed just after Tapas. The way to visualize relative orientation is to use AperiCloud.

RadialBasic

a subset of previous model: radial distortion with limited degrees of freedom ; adapted when there is a risk of divergence of RadialExtended; in this model there are 5 degrees of freedom : 1 for focal length , 2 for principal point and distortion center 3 , 2 for coefficients of radial distortion (r3 and r5 ).

For example with the Mur Saint Martin dataset, you can launch :

Tapas RadialExtended "IMGP41((6[7-9])|([7-8][0-9])).JPG"

Fraser

a radial model, with decentric and affine parameters there are 12 degrees of freedom: 1 for focal length , 2 for principal point, 2 for distortion center , 3 for coefficients of radial distorsion (r3 , r5 r7 ), 2 for decentric parameters, 2 for affine parameters; the optional parameters LibAff and LibDec (def value true) can be set to false if decentric of affine parameters must stay frozen.
