Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0028] The embodiment of the present invention provides a road identification method, which can identify the track points of newly added roads from the GPS track points uploaded by the floating vehicle. Floating cars generally refer to buses, taxis and other vehicles equipped with on-board GPS positioning devices. The GPS track point information uploaded by the floating car includes: latitude and longitude, upload time (return time), floating car ID and speed, etc. Due to the large ...

Abstract

The invention discloses a road recognition method and a road recognition apparatus. The method comprises the following steps: acquiring global positioning system (GPS) track points uploaded by a floating car; matching the GPS track points with a pre-stored road to obtain a set of the GPS track points which are uploaded by the floating car and fail to match with the pre-stored road; filtering and removing the GPS track points in the set useless for the recognition of a new road; and storing rest GPS track points in the set as track points of the new road. Furthermore, the embodiment of the invention provides a road recognition apparatus. By virtue of the technical scheme provided by the embodiment of the invention, the recognition of the new road can be rapidly and efficiently realized with low cost and high precision.

Description

technical field [0001] The present invention relates to the technical field of geographic information, in particular to a road recognition method and device. Background technique [0002] Electronic map data is the basic data of various intelligent transportation systems, and it is of great significance to facilitate people's transportation and solve problems such as urban traffic congestion. Among them, the road is an important part of the electronic map data. Due to the rapid development of the economy, new roads are constantly being built and opened to traffic. Therefore, it is particularly important to update the new roads in time. [0003] For newly built and opened roads, that is, newly added roads, the traditional identification scheme is to obtain the road data of the newly added roads by field personnel through actual measurement, that is, the field personnel use total stations and other surveying and mapping instruments to identify the new roads. The road data is...
