基于视觉传达技术的船舶图像弱小目标跟踪方法

A method for tracking small and weak targets in ship images based on visual communication technology

为了及时发现行驶过程中船舶并及时避开,提出基于视觉传达技术的船舶图像弱小目标跟踪方法。使用视觉传达技术对获取的船舶图像进行去噪处理,采用TDLMS算法通过对去噪后的船舶图像使用模板卷积,检测弱小目标。在此基础上引入模板压缩及空心法进行TDLMS算法改进,提升船舶图像背景预测精度,获取精准船舶图像弱小目标检测结果,并使用直线模型对弱小目标进行跟踪。引入卡尔曼滤波算法对弱小目标的运动轨迹进行预测更新,实现船舶图像弱小目标的实时跟踪。实验结果表明:视觉传达技术的应用可显著提升船舶图像质量,该方法可以有效实现船舶弱小目标不同运行状态下的准确跟踪。

In order to timely detect and avoid ships during their travel,a tracking method for small and weak targets in ship images based on visual communication technology is studied.Using visual communication technology to denoise the obtained ship image,the TDLMS algorithm is used to detect weak and small targets in the ship image by using template con-volution on the denoised ship image.Based on this,template compression and hollow method are introduced to improve the TDLMS algorithm,improve the background prediction accuracy of the ship image,obtain accurate detection results of weak and small targets in the ship image,and track weak and small targets using a straight line model,Introducing the Kalman fil-tering algorithm to predict and update the motion trajectory of small and weak targets,achieving real-time tracking of small and weak targets in ship images.The experimental results show that the application of visual communication technology can significantly improve the quality of ship images,and this method can effectively achieve accurate tracking of small and weak targets in different operating states of ships.
