摘　　要：为了快速、便捷地构建室内平面图,提出一种基于光强信息的室内平面图构建方法。该方法针对行人航迹推算(Pedestrian Dead Reckoning,PDR)算法中存在的“航向漂移”问题,采用四子样旋转矢量算法进行航向估计,通过轨迹拐点自校准算法矫正航向,融合室内光强信息,获取行人在不同区域的PDR轨迹。最后,基于多条PDR轨迹构建精确的室内平面图。仿真结果表明,构建的室内平面图与实际平面图的相似度达到98%。In order to construct indoor plans quickly and conveniently,we proposed a construction method of indoor plans based on light intensity.In view of the"heading drift"problem in the Pedestrian Dead Reckoning(PDR)algorithm,we adopted the four-sample rotation vector algorithm to estimate the course direction,and corrected the path by self calibration algorithm for trajectory turning point.Then,the PDR trajectories of pedestrians in different regions were obtained through the fusion of trajectories and indoor light intensity information.Finally,an accurate indoor plan was constructed based on multiple PDR trajectories.The simulation results show that the similarity between the indoor plan and the actual plan is 98%.
