UAVs Remote Location Algorithm Based on Mesuring Error Correction Compensation

研究无人机的远程距离测量问题,提高测量的准确性;针对无人飞机在进行远程空间距离自动检测的过程中,极易受到天气因素影响,出现机身的晃动,造成采集的数据发生偏差,导致结果不准确的问题;为了解决这一问题,提出一种基于测量误差补偿矫正的测距方法,通过建立新的采集图像坐标系,在新坐标系下对远程采集的数据进行偏移矫正补偿计算,消除无人机在机身晃动、突然变向过程中造成的图像特征失准的影响,提高距离测量的准确度;仿真实验表明,该方法能大幅提高机身在抖动情况下的距离测量准确度,取得了令人满意的效果。

Research drone remote distance measurement and improve the accuracy of the measurement. According to the aircraft in the remote space distance automatic detection process, vulnerable to weather factors, appear the fuselage shaking, cause of the data collected in the produce deviation, not accurate. In order to solve this problem, the paper proposes a kind of based on measurement error compensation methods, through the correct distance to build new acquisition, image coordinate in the new coordinate system to the distance of the data col lected offset for calculating, eliminate UAV correction in the fuselage of rock, suddenly change to be caused by the process of image features, improve the effect of using distance measurement accuracy. Simulation results show that this method can greatly improve the fuselage of the jitter distance measurement accuracy, satisfactory results have been obtained.
