| 摘 要： | 为弥补传统的依靠管理组织、法律、经济、教育等进行对野外地质工作安全管理工作的不足,通过百度SDK采集GPS步行轨迹数据,基于单向GPS轨迹数据的特点,进行轨迹的分割分段处理。最后利用BP神经网络算法拟合道路,通过反复实验确定BP网络的参数配置信息。并以中国地质大学西区为研究区域,提取路网信息,验证算法的有效性和实用性。为野外地质调查工作的信息化建设和救援指挥调度系统建设提供重要的技术支撑。

| Abstract: | To make up for the traditional relying on management organization,law,economy,education and safety management of field geological work,this paper collects walking GPS trajectory data through Baidu SDK.Based on the characteristics of the one-way GPS trajectory data,it accomplishes the trajectory segmentation processing,and finally uses BP neural network algorithm for fitting way,which determines the parameters of BP network configuration information through repeated experiments.The west region of China University of Geosciences is selected as the study area to extract the road network information.The effectiveness and practicability of the algorithm are verified,which provides important technical support for the information system and rescue platform development of field geological survey. |
