 The calibration of the previous section provides 3D information, such as the intrinsic parameters, thanks to the inclination of the calibration grid, but the precision is not optimum, and the process would not converge for a grid perpendicular to the line of view. A more precise procedure consists in first of determining the intrinsic parameters by mutiple views of the same grid with different inclinations.
 
-Once the grid image is correctly set, click on the '''[APPEND LIST]''' button in '''[Point Lists]''' in''' 'geometry_calib''''. This will save the grid as 'img~.xml' file. This document is saved in the same folder as the image. To open it select '''[Import.../Calibration points]'''.

 Now that the calibration is made for the first image we need to do it for the other ones, you can open the different grids '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.

 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.
 
-For the next calibration, to avoid any change on the intrinsic parameters, select the option '''3D_extrinsic''' in '''[calib_type]''' in''' 'geometry_calib''''. It applies a 3D projection and quadratic correction according to the already determined intrinsic parameters.
