A computer-implemented method for calibrating a velocimetry system, the velocimetry system including at least one camera for imaging an illuminated volume comprising moving particles according to at least two different fields of view, the method comprising: receiving a preliminary calibration for the velocimetry system, the preliminary calibration including a set of preliminary imaging equations for each one of the at least two fields of view; simultaneously acquiring different sets of images of the illuminated volume from the at least two fields of view; for each one of the different set of images, voxelizing and reconstructing the illuminated volume, using the corresponding set of images and the received calibration, thereby obtaining a voxelized volume for each one of the different sets of images; dividing each voxelized volume into a plurality of interrogation volumes and generating a template image of each one of the plurality of interrogation volumes for each one of the at least two different fields of view using the corresponding set of preliminary imaging equations; for each interrogation volume and each one of the at least two different fields of view, identifying a match between given clusters of particles contained in the corresponding template image and corresponding clusters of particles contained in the corresponding image of the different sets of images; for each interrogation volume and each one of the at least two different fields of view, determining disparities, based on the corresponding identified match, between a position of the given clusters of particles within the corresponding template image and a position of the corresponding clusters of particles within the corresponding image of the different sets of images; for each one of the at least two fields of view, modifying the corresponding set of preliminary imaging equations based on the determined disparities, thereby obtaining an updated calibration; and outputting the updated calibration. receiving a preliminary calibration for the velocimetry system, the preliminary calibration including a set of preliminary imaging equations for each one of the at least two fields of view; simultaneously acquiring different sets of images of the illuminated volume from the at least two fields of view; for each one of the different set of images, voxelizing and reconstructing the illuminated volume, using the corresponding set of images and the received calibration, thereby obtaining a voxelized volume for each one of the different sets of images; dividing each voxelized volume into a plurality of interrogation volumes and generating a template image of each one of the plurality of interrogation volumes for each one of the at least two different fields of view using the corresponding set of preliminary imaging equations; for each interrogation volume and each one of the at least two different fields of view, identifying a match between given clusters of particles contained in the corresponding template image and corresponding clusters of particles contained in the corresponding image of the different sets of images; for each interrogation volume and each one of the at least two different fields of view, determining disparities, based on the corresponding identified match, between a position of the given clusters of particles within the corresponding template image and a position of the corresponding clusters of particles within the corresponding image of the different sets of images; for each one of the at least two fields of view, modifying the corresponding set of preliminary imaging equations based on the determined disparities, thereby obtaining an updated calibration; and outputting the updated calibration. <EOS>
