摘要
传统无人机定位系统误差消除技术存在误差消除精准度低的问题,需对轻小型无人机遥感定位系统误差消除技术进行深入研究;根据轻小型无人机航线、地理参考和初始位置坐标系,构建轻小型无人机遥感定位模型;利用该模型对目标定位原理展开分析,通过模型构建和无人机隐秘飞行特征,对目标位置进行转换,获取转换后的坐标系位置信息,通过无人机飞行姿势变化幅度范围,获取精准误差影像序号,并进行修正,由此完成系统误差消除;实验结果证明,该技术误差消除精准度较高。
Traditional UAV positioning system error elimination technology has the problem of error elimination and low accuracy.We need to further study the technology of remote sensing positioning system error elimination for light and small UAVs.According to the light and small UAV route,and the initial position of geographical reference coordinate system,the construction of the light and small UAV remote sensing positioning model;using the model to analyze the target positioning principle,through the model and the UAV secret flight characteristics,the target position conversion,coordinate position information is obtained after conversion,the UAV flight posture the change range of precision,error correction and image sequence acquisition,thereby completing the system error elimination.The experimental results show that the precision of the error elimination is high.
