Abstract:
The aim is to establish an automatic system to analyze the maneuver performance of fish.A high speed camera(1 000 frame/s)is employed to record fast-start maneuver.Three steps are taken to analyze the kinematics:first, the midline in the first image is partitioned into equal interval lengths and the coordinates of all inter segmental points are saved.Secondly, these points coordinates are searched in the next frame with the digital image correlation(DIC)method, then these points are fitted with a spline curve function.Repeat this step until all the midlines are figured out frame by frame.Finally, according to the variety of midlines, the kinematics of the fast-start is calculated.Using this system to test carp C-start, the duration is divided into two stages:stage 1 is defined as the formation of the C shape and stage 2 as the return flip of the tail followed with forward motion.By tracing the middle line, the kinematic parameters of turning rate, centre of mass(CM)turning rate, CM turning radius, etc.are obtained.
