Abstract

A method of improving the location accuracy of a target when imaged from an unmanned aerial vehicle (UAV) is described. This method focuses on improving estimation of heading angle bias to then improve geolocation performance. A Particle Swarm Optimization (PSO) algorithm is employed to derive an expression of optimal flight path, which can be a guide for trajectory planning. The aircraft is commanded to fly in the expected path generated by trajectory planning for taking multiple bearing measurements of the ground object. The main result is that the aircraft's heading angle bias can be more accurately estimated using trajectory planning. Hence, the target is more accurately geolocated. The efficacy of this technique is demonstrated by simulation results.
提高基于视觉的目标定位性能的飞机轨迹规划
描述了一种在从无人驾驶飞行器(UAV)成像时提高目标定位精度的方法。该方法着重于改进航向偏置的估计,从而提高定位性能。利用粒子群算法推导出最优飞行路径表达式,为飞行轨迹规划提供指导。命令飞机在对地面物体进行多次方位测量的轨迹规划生成的预期路径上飞行。主要结果是利用弹道规划可以更准确地估计飞机的航向偏角。因此,可以更准确地定位目标。仿真结果验证了该方法的有效性。
