Abstract

The invention discloses a GPS (Global Position System) spatio-temporal data increment road network real-time updating and trace matching system, which comprises a data acquisition module, a GPS spatio-temporal data module, a data pre-processing module, a map trace matching module, a road network generating module and an increment road network updating module. According to the system, the acquired data recorded by a GPS positioner and provided with time and space attributes is pre-processed, a map is matched, a road is generated, a newly formed road section is compared with road network data recorded in a database, road network information is updated, and thus road network data is updated. According to the GPS spatio-temporal data increment road network real-time updating and trace matching system provided by the invention, the road network information is compared continuously with incremental data information, so that a real-time capability is realized, road position information is more accurate along with the increment of data, and roads which are not contained in the road network information are updated.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a GPS space-time data incremental road network real-time update and trajectory matching system. Background technique [0002] In the prior art, the map trajectory matching technology mainly adopts the pattern recognition method, and more matches are performed on discrete location points. Although the accuracy is high, the real-time performance is not strong. The data collection process is to obtain GPS position data with time attributes from a large number of positioning devices, and display them on the map after simple data processing. This method may cause inaccurate applications such as GPS navigation due to unexpected factors such as weather and climate during the actual road data recording process, and at the same time, it cannot accurately and timely locate and update the newly added road conditions. [0003] CN201420519657.4-GPS real-time positioning and electronic map ...
