• Simple 3D Calibration Technique using Image Cross-Correlation

抄録

Three-dimensional Particle Image Velocimetry (PIV) requires that the three-dimensional positiosn of particle tracers in a flow field be found. In this study, a simple and easy calibration technique is proposed, which uses a cross-correlation technique between camera images. The function between image distortion and the Z coordinate (perpendicular to the image) is obtained using a cross-correlation between camera images. The function includes the error of the camera setup and refraction at the test section tank wall. Then the 3D positions can be easily calculated with high accuracy using the calculated function. The technique is applied to the natural convective field, showing the high effectiveness.
