基于光学技术的船模运动跟踪

为准确获得水池中船舶模型的位置和运动姿态,实时对自由运动的船模进行追踪,文中提出了基于光学技术的船模运动跟踪方法,满足了船模运动跟踪的实时性要求。通过对船模进行特殊标记,并在算法中利用关于Battacharyya系数的高斯函数调节核的大小,在不影响实现Mean Shift算法快速性的同时增强了算法的鲁棒性。实验结果表明,在追踪过程中,该算法能够调节跟踪窗口大小,使目标始终出现在窗口中心位置,提高了算法跟踪的准确性。

Motion Tracking of Ship Model Based on the Optical Technology

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.
