Flow velocity inside the artificial ventricle of a moving actuator type total artificial heart is investigated by the image-processing technique. Optical flow is estimated from two sequential images of flow patterns to find flow-velocity distribution. The region with high velocity inside the artificial ventricle is found from the estimated flow-velocity distribution. Fluid velocity in a simple glass conduit is analysed and can be estimated by calculating optical flow.
利用图像处理技术研究了运动驱动型全人工心脏的人工心室内的血流速度。通过血流模式的两幅连续图像估计光流，以确定血流速度分布。根据估计的血流速度分布找出人工心室内高速区域。分析了简单玻璃管道内的流体速度，并通过计算光流进行估计。
