A method and device for digging new roads based on track routes

Abstract

The present invention provides a method and device for digging new roads based on track routes. The method includes acquiring existing road data, and constructing a road topology network based on the existing road data; collecting track data of different users, and mining based on track data Generate multiple trajectories; superimpose the excavated trajectories into the road topology network, and extract the trajectory routes that do not overlap with the roads in the road topology network from the superimposed trajectories; The track route of the road is analyzed to find the roads that do not exist in the road topology network, and the roads that do not exist in the road topology network are added as new roads. The present invention constructs a road topological network by using existing road data, and then sends the collected trajectory data to the background service in time through the background service operation mode and superimposes it on the road topological network, and can quickly and conveniently find out through the superposition result Added new roads to greatly improve the timeliness of discovering newly opened roads.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method and device for mining new roads based on track routes. Background technique [0002] At present, the conventional way to collect new roads is that no matter whether there are new roads or not, professionals will drive out to collect them on the spot first. If there are new roads, they will be collected. This method leads to high manpower and material costs for collecting new roads, and the required period is long. Another way to collect new roads is to first obtain the newly opened route information published on the Internet, and then let the staff go to the field to collect and verify it. However, this collection method has poor effectiveness and cannot discover newly opened routes in a timely manner. . [0003] Therefore, the acquisition of newly added roads in the prior art requires a large amount of human resources, and the timeliness is poor, and th...

Another way to collect new roads is to first obtain the newly opened route information published on the Internet, and then let the staff go to the field to collect and verify it. However, this collection method has poor effectiveness and cannot discover newly opened routes in a timely manner.

[0003] Therefore, the collection of newly added roads in the prior art requires a large amount of human resources, and the timeliness is poor, and the data information of newly added roads cannot be obtained in a timely manner.
