Web26 de mai. de 2005 · A stereo-PIV (stereo particle image velocimetry) calibration procedure has been developed based on fitting a camera pinhole model to the two cameras using single or multiple views of a 3D calibration plate. A disparity vector map is computed on the real particle images by cross-correlation of the images from cameras 1 and 2 to … Web7 de mai. de 2014 · The reason for the hovering dragonfly having similar natural modes of motion to those of a one-wing-pair insect in normal hovering is that they have similar stability derivatives. As can be seen from Table 3 in Sun et al. (2007) , for an one-wing-pair insect in normal hovering, M u + , X u + and Z w + have large magnitude, with M u + …

Weblaboratory-fixed frame of referenceat time t =0, the plate is iny=0,−L/2 x L/2 (see figure 1). For t 0, the plate moves into the third quadrant, without rotation, with speed U(t) and in a straight-line trajectory such that its centreline makes an angle α with the negative x-axis. The plate speed profile is of power-law form U(t)=Btm, (2.1)
