Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0042] Such as figure 1 As shown, the present invention relies on road network big data, carries out network topological relationship construction to road data and publishes road network map service and dynamic segmentation processing, forms road unit; Combined with the road network map service to correct the GPS track information; then match the road where the current disease is located according to the map path matching algorithm, and finally use the road disease location information uploaded by the GPS Track terminal combined with the road unit data to automatically calculate the relative distance In order to realize the rapid determination of the relative position of road diseases during the road network maintenance inspection process, it can efficiently serve the road maintenance inspection and other work.

[0043] The invention can effe...

Abstract

The invention provides a method and system for fast determining road network disease relative positions and belongs to the field of road maintenance. The method includes: preprocessing road data; performing dynamic road segmentation to form road unit information, and building a road network map service at the same time; correcting patrol trajectories, to be more specific, by a patrol terminal, correcting GPS trajectory information according to the road network map service; matching roads, to be more specific, when diseases exist, by the patrol terminal, matching the roads where the current diseases are located according to a map route matching method; by the patrol terminal, updating disease position information and disease feature information; determining the disease relative positions, to be more specific, calculating the relative positions of the current diseases according to the disease position information uploaded by the patrol terminal. By the method and system, road patrol efficiency is increased, and patrol time cost is saved.

Description

technical field [0001] The invention relates to the field of road maintenance, in particular to a method and system for quickly determining the relative position of road network diseases. Background technique [0002] With the continuous expansion of the scope of smart city construction advocated by the state and the continuous deepening of smart city theory and practice exploration, the application of smart city construction has greatly accelerated the speed of data generation, and the improvement of data-driven urban operation and management capabilities has entered a new stage. The precise service supply and urban operation model based on , storage, sharing, and openness are favored; as the transportation field of smart city construction, intelligent road maintenance inspections come into being. [0003] At present, the determination of the relative position of road diseases in road maintenance inspections is mainly based on the inspection personnel relying on laser instr...
