The invention discloses a method for realizing accurate
route navigation by combining a wild road network with a public map. The method comprises the steps of
route planning request and preprocessing, parallel acquisition and topology reconstruction of multiple alternative routes, fusion
network data set construction, intelligent
route analysis and
optimal route generation and output. According to the method, deep seamless fusion of a public road network and a dynamic wild road network in a
data level and a planning level is realized, the problem of route interruption caused by data missing in a field area in traditional navigation is solved, whole-course continuous navigation guidance from a city to a wild area and from a main road to a small
diameter between mountains is provided for users, and the user experience is improved. Intelligent path analysis is carried out by introducing a multi-factor weighted scoring model, only the
shortest distance or time is not pursued any more, multi-dimensional costs such as
terrain complexity, path maturity, pavement conditions and safety are comprehensively evaluated, and a personalized path which achieves optimal balance among efficiency,
physical exhaustion and risks is planned; and the safety and experience of outdoor activities are obviously improved.
