Abstract

The invention provides a road surveying and mapping method and a road surveying and mapping system. The method comprises the steps of enabling the original data of all vehicles acquired by location to form a single vehicle track set within a preset time period; carrying out road matching by the single vehicle track set and a spatial index established according to the road segment data of a base road network; carrying out correlation analysis on the single vehicle tracks which are not successfully matched according to the areas to confirm the relevant combinations as well as the fitted curves and the road grades of the relevant combinations; supplementing the road segment data of the base road network by the possibly missing roads confirmed according to the fitted curves and the road grades to form the road surveying and mapping result. The actual driving single vehicle tracks of the vehicles are matched with the existing base road network, the possibly missing rods can be obtained by the correlation analysis mass of single vehicle tracks, and the road segment data of the base road network is supplemented by the possibly missing rods; the method and the system are shorter in surveying and mapping period, controllable in surveying and mapping replacement cycle, high in accuracy of surveying and mapping result and timely in data updating.

Description

technical field

[0001] The invention relates to the technical field of data processing, in particular to a road surveying and mapping method and system. Background technique

[0002] The surveying and mapping of basic road network data is mainly carried out by the government, commercial surveying and mapping companies authorized by the government, and the military. Among them, the military's surveying and mapping results are the most detailed, but they are exclusively used by the military and have not been commercialized; while the government's surveying and mapping is provided to the government in charge of land, geological surveys, cadastres, etc., and the other part will be paid for external development; Commercial surveying and mapping companies authorized by the government usually serve the market entirely. The above-mentioned surveying and mapping is usually divided into two processes: field work and internal work. The field work is the process in which surveyors and ...
