Abstract:

In order to obtain the position and motion of the ship model in wave basin and track the moving ship model real-time,a method based on the optical technology is proposed to meet the real-time requirement of tracking moving ship model by scaling the core of stamped area.With a special mark on the ship model and using the Gaussian function with respect to the Bhattacharryya coefficient to adapt the scale of stamped core,the robustness of mean shift algorithm is enhanced while keeping the advantage of high speed.Experiment results indicated the algorithm can scale the window of identification adaptively and restrict the mark in the center of the window,thus improving the accuracy of tracking.
