v179 v180 586 586 -''' Opening the GUI: ''' it is made visible from the GUI '''uvmat.fig''' by the menu bar command '''[!Tools/Geometric calibration] '''. If calibration data already exist in the current file <!ImaDoc>, the corresponding parameters and the list of reference points are displayed in the table '''[!ListCoord]'''. The three first columns indicate the physical coordinates and the two last ones the corresponding image coordinates (in pixels). The physical unit is imposed as centimeter by the menu '''[!CoordUnit]''' to avoid mistakes. Calibration points can be alternatively introduced by opening any XML file <!ImaDoc> with the menu bar command '''[Import]''' of '''geometry_calib.fig'''. It is possible to import the whole information, option 'All', the calibration point coordinates only, or the calibration parameters only. 587 587 588 -''' Plotting calibration points: ''' press the button '''[PLOT PTS] ''' to visualise the current list of calibration points. The physical or image coordinates will be used in the list '''[!ListCoord]''', depending on the option blank or 'phys' in the menu ''' [transform_fct]''' of ''' uvmat.fig''' .588 -''' Plotting calibration points: ''' press the button '''[PLOT PTS] ''' to visualise the current list of calibration points. The physical or image coordinates will be used in the list '''[!ListCoord]''', depending on the option blank or 'phys' in the menu '''transform_fct''' of ''' uvmat.fig''' . 589 589 590 590 -'''Simple scaling''': a simple scaling, in pixels/cm, can be introduced by the menu bar command '''[!Tools/Set scale]''', which displays a set of four reference points in the table '''[!ListCoord]'''. The tool 'ruler', from the menu bar command '''[Tools/ruler]''' of '''uvmat.fig''', can be useful to get the scaling. The origin of the physical coordinates is set by default to the lower left image corner. Use the tool 'translate points', described below, to change the origin. 591 591 592 -''' Appending calibration points with the mouse: ''' Calibration points can be manually picked out by the mouse on the current image displayed by '''UVMAT''' (left button click). This requires the activation of the check box ''' [enable mouse]'''. The image coordinates (in pixels) are picked by the mouse (the option 'blank' in the popup menu '''[transform_fct]''' is automatically selected when the mouse button is pressed). Zoom can be used to improve the precision, but must be desactivated for mouse selection (then move across the image by the key board directional arrows). Points can be accumulated from several images, using the key board short cuts 'p' and 'm' to move in the image series without the mouse. A calibration point can be adjusted by selecting it with the mouse and moving it while pressing the left mouse button. The coordinates in pixel of the selected points get listed in the table '''[!ListCoord]''' of '''geometry_calib.fig'''.592 -''' Appending calibration points with the mouse: ''' Calibration points can be manually picked out by the mouse on the current image displayed by '''UVMAT''' (left button click).

To make this task easier it is possible to export the table content on the Matlab command window by pressing '''[COPY PTS]''', and copy-paste a column on the table '''[!ListCoord]''' (the column below the introduction cell is filled). A single point can be removed by the 'backward' or 'suppr' keyboard command after selecting its line on the table. The whole set of points can be removed by pressing '''[CLEAR PT]'''. They can be also removed by pressing '''[STORE PT]''', then stored in a XML file (whose path and name is listed in '''[!ListCoordFiles]'''). Stored points can be retrieved by the menu bar command '''[Import/calibration points]'''.
