Observe the motion by scanning the images.8 Open an image 'UVMAT_DEMO05_displacement/images'. This is a target pattern used to measure the displacement of a plate versus time. Observe the motion by scanning the images. 9 9 10 Make a mask to remove the outer part in the PIV processing, like explained for tutorial 5, or introduce the mask provided .ref (selecting the upper bar button .. in uvmat)10 Make a mask to remove the outer part in the PIV processing, as explained in tutorial 5, or introduce the mask provided .ref (selecting the upper bar button '''[Projection object/browse..]''' in '''uvmat''') 11 11 12 '''Civ in mode 'displacement':''' 12 == Civ in mode 'displacement' == 13 13 14 Open series/civ_series. import Config for ref file, .ref . The appropriate parameters aredisplayed:14 Open '''series/civ_series''' and import the configuration from the reference file .ref. The appropriate parameters are then displayed: 15 15 16 16 * mode displacement, with respect the origin index 1 (first image by default). Then the menu for choosing image pairs desappears, as the correlation for each image are done with respect to the reference one, taken as origin for the displacement. … … 22 22 * Civ2, same correlation box, smaller search zone as we start form the prediction of Civ2 (shift) 23 23 24 '''Observing the civ data:''' 24 == Observing the civ data == 25 25 26 26 velocity, vorticity, div 27 27 28 '''Time series:''' 28 == Time series == 29 29 30 30 Make a point, range=200, and run series/time series.
