Procedure for determining the mapping equation for self-calibration in relation to the implementation of stereo PIV procedures

摘要

The invention relates to a method for determining the mapping equation for self-calibration in relation to the implementation of stereo PIV methods in visualized flows, comprising at least two cameras and an image section, the cameras in approximately the same area of the light section, but from different ones Consider directions, the point correspondence between the two cameras being determined by measuring the displacement of the respective interrogation fields in the camera images by means of optical cross-correlation, the imaging equation being determined with the aid of known internal and external camera parameters using an approximation method.
