摘要
基于单目图像上的特征直线,提出了一种适合于飞机目标的姿态测量算法;引入基于异面直线和共面直线的解析方法直接计算姿态初值,并改进了传统正交迭代(OI)算法,得到了适用于姿态测量的直线特征正交迭代方法,将初值进行该迭代得到最终结果,该方法有效利用了直线特征提取精度高,稳定性好,抗遮挡能力强等优点;采用仿真实验中飞机距离在6km以内,姿态角的误差可达到1°以内;实验结果表明,方法适用于单目测量飞机姿态,测量结果精度较高,稳定性好。
The research introduces a pose measurement algorithm of aircraft based on lines on a monocular image. First, we used the linear methods based on bifacial and coplanar lines to calculate the initial pose. Then, we improved the traditional OI algorithm, and found a new OI method based on line features to calculate the pose of aircraft. This method makes full use of the stability, accuracy of line features. We simulated the method and the result was that the attitude error was below than 1 when the distance was whthin 6km. The result shows that this method applies to monocular pose measurement of aircraft, and it is precise and stable.
