摘要:

利用遥感图像进行舰船检测与监视的研究和技术开发在海洋遥感领域得到了快速发展,并成为遥感数据重要的海洋应用之一。当海洋遥感图像用于舰船尾迹检测时,就可及时有效地发现和提取舰船目标信息。文中利用光学遥感图像的海面舰船尾迹特征以及相关参数,估测舰船目标的速度与航向。分别通过灰度累积法和Radon变换法两种不同的尾迹长度检测方法,对尾流长度进行了提取,并利用尾流长度特征简单估测了舰船航速与航向。对实验结果和误差进行了分析,并对影响舰船尾流检测的因素进行了讨论。估算结果初步验证了对航速与航向估算方法的有效性

Abstract:

In recent years,the use of remote sensing images for ship detection and surveillance and technological development has received considerable attentions in the field of ocean remote sensing.This issue has been one of the most important marine applications of remote sensing data.When the ocean remote sensing imagery is used for ship wake detection,one can discover and extract ship target information quickly and effectively.The main work of the article is to estimate ship target speed and heading by using the ship wake characteristics in the remote sensing ocean images.We use gray accumulation method and Radon transform method separately to extract wake length,and with the feature of wake length we can estimate ship speed and heading.Finally,the experimental results and error analysis are accomplished and the influencing factors in the process of ship wake detection are described simply.The experimental results verify the validation of the proposed method.

Key words: remote sensing images;image process;ship detection;wake stream;parameter estimation
