Real Time Fish Tracking Method Based on xPC Target

The research on the mechanism of flexible bionic fish propulsion based on modal analysis is to develop a high-speed and efficient bionic swing propeller by studying the relationship between the swing frequency of soft-body bionic fish and its velocity. How to accurately track the real-time path of bionic fish has become the core issue of developing propellers. The motion estimation by an improvement mean shift algorithm is added to track the path of the bionic fish on xPC-Target platform. According to dual-target setting, two-dimensional coordinates are converted to three-dimensional coordinates. The position coordinates of the bionic fish swimming in real time are obtained. The actual position of fish swimming is compared with the tracking position, which determines the tracking accuracy.
