Abstract
The multiphase flow measurement system and method includes video sensors and illumination along a pipe upstream, and a similar arrangement of sensors and illumination downstream displaced from the first location by a known distance utilized for velocity calculation between images at both locations. Image capturing and processing is done from video data at both locations. Objects corresponding to each flow phase in the video images are characterized and sorted by size, color, spectral properties, shapes, and pattern features using automatic pattern recognition. Image cross-correlation and pattern recognition are applied to each group of objects corresponding to one or more flow phases to estimate the velocity of each phase based on the delay calculation. Flow velocity is calculated from the weighted average of the phase velocities. Overall flow type is estimated using the estimated phase velocities and the areas occupied by the objects corresponding to each phase in the images.
