基于图像纹理特征提取的船舶目标定位方法

Ship target location method based on image texture feature extraction

普通船舶目标定位方法,确定目标船舶所处位置时,易发生较大偏差,且所需定位时间过长。为有效解决此问题,设计基于图像纹理特征提取的船舶目标定位方法。通过船舶图像纹理特征的确定,完成基于Gabor船舶图像纹理特征的提取。通过目标阵列稀疏信号的确定、稀疏信号方位角的确定,完成基于图像纹理特征提取的船舶目标定位方法的搭建。设计对比实验结果表明,新型船舶目标定位方法与普通方法相比,一定程度上,缩小目标船舶定位误差及所需定位时间。

The ordinary ship target positioning method,determine the target ship position,prone to large deviation,which needs long time positioning.To solve this problem,the design of ship target localization method based on image texture feature extraction.By determining the ship image texture features,complete texture feature extraction based on image Gabor ship.By determining the sparse signal azimuth determination,target array of sparse signals,built the ship target localization method based on image texture feature extraction.The experimental results show that compared with the contrast design,new ship target localization method with the general method,to a certain extent,reduce the target ship positioning error and positioning time required.
