飞机迎角、侧滑角传感器图像检测系统的研制

利用图像处理技术，详述了飞机迎角、侧滑角图像的获取、边缘增强的目标分割、亚像素计算、定标误差修正、控制和处理单元的选择、转角电压检测与转换等技术难点的解决。经验证：此方法得到的检测结果稳定可靠、准确度及自动化程度高，代替老式的测角仪，可推广到主机厂、部队、航修厂、院校等单位。

Development of image detecting system for the plane''''s heading and yawing angle sensors

Using image processing technology,the problem of plane's heading angle and yawing angle images,edge enhancement,goal decomposition,subpixel calculation,scaling error correction and controlling,selection of processing unite,detecting and converting of corner voltage detector were elaborated.It has been proved that the detecting result is stable,accurate with high automation so that the system can replace the old fashioned goniometer and widely used in main engine plants,unit,aviation maintenance and colleges.
