主　　题：Particle tracking velocimetry(PTV) Camera Unsteady flow Velocity 

摘      要：This paper presents a large-scale particle tracking velocimetry(LSPTV) system for measuring surface velocity in vast unsteady *** system consists of a flexible number of one-computer-six- camera working units connected via local network or the *** zero-tilting cameras are used to increases the field of view with minimum perspective *** synchronization of video outputs of all cameras facilitates uninterrupted image acquisition within the *** and efficiency of the multi-channel LSPTV are enhanced by optimizing illumination,flow seeding, image acquisition and correction,tracer identification,particle matching,and *** capacity of the LSPTV was demonstrated in the measurement of physical model flows for the Three Gorges Project.
