摘要：

A video system for tracking a free-swimming fish two-dimensionally is introduced in this paper. The tracking is accomplished by simultaneously taking images from the ventral view and the lateral view of the fish with two CCD cameras mounted on two computer-controlled and mutually orthogonal translation stages. By processing the images recorded during tracking, three-dimensional kinematic parameters of the tail and pectoral fin of the fish in forward, backward and turning swimming modes are obtained.
