航空图像目标识别算法研究

根据飞机的对称性特点,提出了一种航空图片中智能判别飞机类型的方法。通过寻找其重心,检测飞机的位置,然后以飞机的重心为矩心,根据矩不变原理,通过旋转将飞机的中轴线和坐标轴Y轴重合,由飞机的轴对称特点求出三个基本特征量,利用匹配的方法就可在航空图片中正确地识别型号不同、大小各异、位置任意的各种地面飞机,而且识别特征少、计算量小,识别速度快,识别正确率高。

Algorithm approaches of aerial films recognition

A new method which recognizes the aircraft models in aerial film according to the symmetry feature of aircraft is addressed.This method is based on moment invariants theory and selects CG(Center of gravity)as original point.With three basic invariable features including the ratio of length and width,the projected value of X-axis,the projected value of Y-axis,all kinds of aircrafts can be recognized.This method which can identify the target with little computation,high speed and high ratio of aircraft recognition is proved effective.
