Claim 6:
7. The method for morphological identification, trajectory tracking, and velocity measurement of the high-concentration microbubbles according to claim 1, wherein obtaining instantaneous velocity field information of the microbubble group of step 5), further comprises:
calculating a change rate of displacement to time according to a correspondence of each microbubble at different instants to obtain velocity and direction information; and
marking a velocity vector in an initial high time-resolution image of the microbubbles;
in which a bubble position changes slightly in each image of the microbubbles taken by the high-speed CMOS camera at each instant; and after bubble positions at different instants are correlated, taking a change rate of each microbubble's displacement to time as a velocity at the current instant, and obtaining a velocity field of all the microbubbles at each instant.
