Coordinate Positioning of Turbulence Tracing Particle based on Cross Correlation Matching and Image Projection Transformation
Coordinate positioning of turbulence tracing particle based on cross correlation matching and image projection transformation is investigated. On the basis of extracting wavelet high-frequency components of turbulence conjugate sequential images in continuous time-points, cross correlation matching is applied to definite tracing particles relative location in the projected images, and then relationship of three-dimensional projection transformation is established to calculate particles absolute space coordinates. Experiment analysis and data comparison indicate that accurate coordinate positioning result of tracing particle can be obtained by this method, turbulence feature and its motion discipline can be displayed finely.
