飞行器远程图像距离测量方法研究

针对无人飞行器在进行远程空间距离自动检测的过程中,极易受到机身晃动、翻滚的影响,造成采集的图像数据误差较大,测量效果不准的问题.文中提出一种基于倾斜误差补偿矫正的飞行器采集图像测距方法.通过建立立体转化坐标系,在新坐标系下对远程采集的数据进行数据倾斜误差的计算并且进行矫正,消除飞行器在机身摇摆、方向突变、倾斜过程中造成的图像配准特征误差较大的影响,提高距离测量的准确度.仿真实验表明,该方法能大幅机身颠簸、翻转情况下的距离测量准确度,取得了令人满意的效果.

Image Remote Distance Measurement Method of Aircraft

For unmanned spacecraft in space distance remote of automatic measurement of process,vulnerable to the fuselage of rock,the influence of the tumbling,causing the image data collected much error,and the measurement of the problem of no effect.Is proposed based on a tilt error compensation of aircraft image acquisition range correction method,by establishing three-dimensional coordinate transformation,in the new coordinate system to the distance of the data collected data calculation and tilt error correction,eliminate the aircraft fuselage swing,direction of mutation,tilt caused by the process of image registration error greater influence on the characteristics,improve distance measurement accuracy.Simulation results show that this method can greatly the turbulence,flip cases of distance measurement accuracy,satisfactory results have been obtained.
