摘要:: 在利用无人机提取道路交叉口空间信息过程中,由于很难实现对无人机的精准控制以及无法准确定位无人机位置,导致航测数据挖掘准确率过低以及时间过长。因此,为解决这些问题,提出基于无人机航测技术的道路交叉口空间信息提取方法。利用卡尔曼滤波构建无人机状态方程与观测方程,根据状态方程和观测方程获取无人机位置信息,完成无人机的准确定位;采集无人机航测信息,利用采集到的信息构建道路交叉口空间三维模型,实现道路交叉口空间信息提取。实验结果表明,该方法在环境恶劣情况下,可以准确定位无人机位置,航测数据挖掘准确率高以及信息提取时间短,实际应用效果更好。

Abstract:: Currently in the process that UAV is utilized to extract the road intersection space information , because it is difficult to achieve precise control of UAV and unable to accurately position the UAV , the aerial data mining is of low accuracy and time-consuming , so in order to solve these problems , this paper proposes an extraction method of intersection spatial information based on UAV aerial survey technology.Kalman filter was used to construct the UAV state equation and observation equation , and the UAV position information was obtained according to the state equation and observation equation.The UAV aerial survey information is collected , and the three-dimensional spatial model of road intersections is built with the collected information to realize the spatial information extraction of road intersections.The experimental results show that this method can accurately locate the UAV position under harsh environment , with high accuracy of aerial survey data mining , short time of information extraction , and better practical application effect.
