Research on Construction Method of Underground Cable Path Network Based on GPS

Abstract

In view of the frequent excavation of underground cables in the city and the fact that the municipal management department does not update the underground cable path network in time, which leads to the chaos of urban underground cable management, a method for quickly constructing a cable path network is proposed. The method uses GPS positioning function and cable path detection technology, and combined with MATLAB image processing to quickly build an underground cable network of urban roads. The GPS data acquisition system is mainly responsible for cable positioning and data processing, using chain coding technology to process the data and extract effective feature points. Using MATLAB image processing can quickly generate feature scatter plots, at the same time generate all cable path networks as needed, or update the specified segment path network. The experimental results show that the formed path network reflects the real cable path better, and the research results provide great convenience for urban planning and construction.
