摘要
文章研究了基于傅里叶描述子的形状特征匹配方法在机场掩体检测中的应用。本文利用傅里叶描述子对目标旋转、缩放和平移描述的不变性,确定了用基于傅里叶描述子的特征匹配方法来检测掩体目标,并对匹配方法的原理、步骤和方案进行了论述。用仿真数据进行了试验,试验结果验证了文中设计的形状匹配方法对掩体类目标检测的有效性。
A method of shape features matching based on Fourier Descriptors （FD） is studied in this paper. The FD is invariant to the transforms of rotation, scaling and shift, when it is used to describe the shape features. Thus, the matching method based on FD is used to detect the airport shelters in this paper. The theories and methods of matching shape features based on FD is studied. The simulation results show the efficiency of the proposed method.
