    72 Once the grid image is correctly set, click on the [APPEND LIST] button in [Point Lists]. This will save the grid in 'img~.xml'. This document is saved in the same folder as the image. To open this document select [Import.../Calibration points].

    74 Now that the calibration is made for the first image we need to do it for the other ones (you can also open the different 'img.ref~.xml' to skip the calibration). Once a document is open, the grid is shown in '''uvmat''', to save it in the [Point Lists] click on [APPEND LIST], it will appear below the first saved document.

    76 When all the grids are selected in [Point Lists], select [APPLY]. The calibration on every image is now made and the values of the intrinsic parameters are reevaluated according to the different data determined by every calibration. Note that the more images used for the calibration, the more precise the intrinsic parameters will be.

    7878For the next calibration, to avoid any change on the intrinsic parameters, select the option '''3D_extrinsic'''. It applies a 3D projection and quadratic correction according to the intrinsic parameters.
