无人机多传感器数据融合的设计要求

The Requirements on the Data Fusion of Multiple-sensor of UAV

无人机在程控飞行状态下,其飞控系统要具有较高精度的飞行参数,才能使无人机安全飞行。传感器是其采集数据的重要途径,然后单个传感器往往不能够提高高精度的数据,为程控飞行带来了不确定性。通过介绍系统传感器数据融理论,并推导了符合高度及姿态角精度要求的计算公式,梳理了应用该技术的方法和算法,进而对引入融合技术后的通道进行了分析。研究表明,通过MSDF技术,在不改变原结构的基础上,能进一步提高飞控系统的可靠性。

The control system of UAV, in controlled flight, needs high-accuracy flight parameter to ensure safe flight.Sensor is the important source of data. But single sensor cannot provide high-accuracy data, which jeopardizes the safety of controlled flight. This paper introduces the data fusion of multiple-sensor, deducts the formulation that can calculate the height and angel at the required accuracy, analyzes related methods and algorithms, and finally studies the channel after the integration of the fusion technology. The research shows that MSDF could improve the reliability of the control system without changing its original structure.
