矿井环境下无人机视觉PSOFastSLAM算法的实现
摘要
为了实现无人机在无GPS的矿井环境下进行自主飞行,达到无人机的精准定位,提出了基于Rao-Blackwellized粒子滤波器的快速同步定位与地图创建(fast simultaneous location and mapping
In order to realize the autonomous flight of Unmanned Aerial Vehicle (UAV) in the mine environment without GPS and also precise positioning it
an algorithm called Fast Simultaneous Location and Mapping (FastSLAM) which is based on RaoBlackwellized particle filter is proposed.Firstly
an artificial road sign suitable for underground mine was designed and the mathematical model of Simultaneous Location and Mapping (SLAM) algorithm for UAV was established.Then an improved algorithm called PSOFastSLAM was proposed to improve the accuracy
to estimate the pose of UAV and the position of guideposts and to achieve the accurate positioning and map building for UAV.Finally
the simulation experiment is simulated
simulation results show that PSOFastSLAM algorithm can improve the particle degeneration problem in FastSLAM algorithm effectively and improve the positioning accuracy of UAV.
