基于局部和整体特征的飞机识别方法

摘要

With the improvement of the satellite image resolution,in order to distinguish the aircrafts in the airport more ac⁃curately,the limited recognition area is got first through image segmentation,and then each area of the image is judged accor⁃ding to the local feature and global feature in the image,so as to suppress the interference region. For the sake of reducing air⁃craft recognition time,the image matching methods is used to fix the plane direction so that all⁃around airplane images are not needed,thus the number of aircraft images and calculation complexity are greatly reduced. The experimental results show that this method has a good recognition effect in the identification of aircraft.%　　随着卫星图片分辨率的提高，为了更准确的对机场区域飞机进行识别，首先对图像分割得到待处理的有限识别区域，然后采用局部特征和整体特征对图像中各区域进行判定，排除干扰区域。同时为了减少飞机识别时间，用图像配准方法将测试飞机方向固定，这样飞机库中不需要全方位的飞机图片，大大减少了飞机数量，减小了计算复杂度。实验结果表明该方法在飞机识别中有较好的识别效果。
