Starting from the principal of motion estimation of optical flow field, a novel DPIV image processing algorithm, namely the consecutive motion vector estimation algorithm, is proposed and applied to study the granular flow field in the transverse plane of a partially filled rotary cylinder.
从DPIV图像诊断所依据的光流场运动矢量估值的原理出发,发展了结合流体固有特征信息的连续性运动矢量估值算法,并应用于回转圆筒内颗粒流场的定性测量。
