| 摘 要： | 利用流场实验平台对仿生实验的风洞环境进行模拟，以航模飞机为检测对象，给出了一种基于双摄像机的视频图像飞行姿态检测方法。利用颜色特征分别提取两路视频图像中的飞行航模目标，采用提取直线的方法获得航模目标中的直线参数，通过直线参数的变化分别解算飞行的横滚角和俯仰角姿态。与AHRS航姿参考系统MIN—IVA900的数据进行对比表明：该方法检测结果的最大偏差小于1°，取得了飞行姿态检测结果的一致性。

| Abstract: | Use flow field experimental platform to simulate wind tunnel environment, makes a model aircraft as detection object and adopts a video image-based method for flight attitude detection using two cameras. The model aircraft targets in the two path video images are extracted respectively based on its color feature, then straight line extraction approach is employed to obtain parameters of straight lines in model aircraft target, and roll angle and pitch angle attitude are calculated through the change of parameters of straight lines. Compared with datas of attitude and heading reference system （AHRS） MIN-IVA900, the maximum deviation of the detection method is less than 1° ,and that indicates the consistency of flight attitude detection result. |
