Method for recognizing unknown roads in current navigation map and carrying out navigation on unknown roads

Abstract

The invention discloses a method for recognizing unknown roads in a current navigation map and carrying out navigation on the unknown roads. The method comprises the following steps: (1) collecting and extracting information of unknown roads: obtaining the initial driving track data through track collection, processing and analyzing the track data to extract the information of unknown roads, integrating the unknown roads into known roads, and providing the map for navigation; (2) carrying out navigation on unknown roads: after the information of unknown roads is obtained, calculating the navigation information (turn-around direction and turn-around distance) of unknown roads, combining realtime positioning, and matching the realtime position to the current unknown roads to realize realtime navigation. The provided method can extract the information of unlabelled roads, which exist on a navigation map, through historical tracks, conveniently navigates drivers on the unknown roads, avoids the phenomenon that the drivers are detoured or cannot reach the destination due to slow update of navigation map, and is suitable for the field of logistics distribution.

Description

technical field [0001] The invention relates to a method for identifying and navigating unknown roads, in particular to a method for collecting, identifying, analyzing and navigating unknown roads that are not identified in a navigation map during the logistics distribution process. Background technique [0002] GPS technology has been widely used in various fields. Various applications such as navigators, navigation maps, and mobile APPs developed based on GPS technology are also widely used in work and life, but these map applications can only be carried out on the basis of identified roads. navigation. In reality, many roads actually exist, but have not been collected in the navigation map, resulting in the inability to directly navigate to the destination or take a long detour. This phenomenon is especially common in rural areas. Contents of the invention [0003] The purpose of the present invention is to provide a method for identifying and navigating unknown roads ...
