The invention discloses a kinematics recording device for free swimming of a dolphin, and belongs to the field of bionic fluid mechanics. The invention aims to solve the problem of large errors of acquired dolphin swimming track data in the prior art. The transparent water tank is used for providing a swimming space for the dolphin, and the lighting source provides illuminance; the first high-speed camera is centered corresponding to one side wall of the transparent water tank; the second high-speed camera is centered corresponding to one end wall of the transparent water tank; the first laser emitting device corresponds to the other end wall of the transparent water tank, and the second laser emitting device corresponds to the opposite side wall of one side wall of the transparent water tank. A first laser receiving device is arranged on the first high-speed camera, and a second laser receiving device is arranged on the second high-speed camera; and the laser receiving device controls the triggering of the shutter of the corresponding high-speed camera after receiving the signal transmitted by the laser transmitting device. According to the invention, the accurate recording of dolphin kinematics data is realized.
Description
technical field [0001] The invention relates to a kinematics recording device for free swimming of dolphins, belonging to the field of bionic fluid mechanics. Background technique [0002] With the acceleration of the pace of ocean exploration, various underwater vehicles have developed rapidly. Whether in the military or civilian fields, underwater vehicles play an irreplaceable role. [0003] A variety of fish in the ocean have gone through a long process of environmental adaptation, and have excellent performances such as high-speed swimming, low energy consumption, and low noise. Based on this, many experts and scholars put the focus of underwater vehicle research on the manufacture of fish-like underwater robots. Compared with traditional underwater robots, fish-like underwater robots have the following advantages: [0004] First of all, the streamlined shape makes it have excellent hydrodynamic performance, high swimming efficiency and low energy consumption; Reduc...
