针对粒子图像测速(PIV)中速度矢量由于折射率引起的光学畸变进行了系统校正研究,提出了一种用于柱状曲面容器内PIV测量的径向光学畸变校正方法。并应用于泰勒一库埃特流测量的校正。
The study on system calibration was completed for the sake of optical distortion correction due to refraction on the wall of arbitrary curve-shaped cylinder in particles image velocimetrey (PIV). A method of radial distortion calibration for PIV measurement was presented. The results of calibration for PIV measurement of Taylor-Couette flow are successful.
