v17 v18 13 13 Open the menu bar '''Tools/geometric calibration'''. A new GUI '''geometry_calib''' appears on the right side. Activate the upper menu bar '''!Tools/Set scale''' on this GUI and introduce the value 70 in the edit box which pops up, and validate with '''OK'''. A set of calibration point coordinates appears in the table '''[!ListCoord]''' of the GUI. 14 14 15 To see the calibration points on the image, first display the whole image by unselecting '''fix''' (tag '''[!CheckFixLimits]''') in the frame ''' Coordinates''' of uvmat. Then press '''PLOT PTS''' in '''geometry_calib'''.15 To see the calibration points on the image, first display the whole image by unselecting '''fix''' (tag '''[!CheckFixLimits]''') in the frame '''Axes''' of uvmat. Then press '''PLOT PTS''' in '''geometry_calib'''. 16 16 17 17 To perform the calibration, press '''APPLY''', first with the default option 'rescale' in '''calib_type'''. The image is now displayed in phys coordinates. A xml file 'images.xml', containing the calibration parameters and reference point coordinates, has been created in the folder 'UVMAT_DEMO01_pair' (it should be identical with the file 'images.ref.xml' put for reference). [[BR]]Note that the xml file name reproduces the name of the folder containing the images, so that images from different cameras should not be
