Abstract

The invention discloses a navigation method and device. The method comprises the following steps: acquiring starting-point information and end-point information; finding a starting-point grid code andan end-point grid code in a navigation database, wherein the navigation database at least comprises coding information and grid sizes of multiple points; determining position information of an end point respectively according to the starting-point grid code, the end-point grid code and the grid size, wherein the position information of the end point comprises an end-point direction relative to the starting point, the end-point distance relative to the starting point and the end-point height. The navigation method and device disclosed by the invention have the beneficial effects that the technical problem that the navigation efficiency is low due to failure of three-dimensional space navigation in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of navigation, in particular to a navigation method and device. Background technique [0002] Navigation has always been a research hotspot in the fields of robotics, virtual scene and geographic information science. It refers to the process of finding a path from the starting position to the target position that meets certain criteria in a given environment. The research on navigation methods has a long history. In recent years, scholars at home and abroad are constantly proposing improvements to classic navigation algorithms. Traditional navigation algorithms are mainly divided into vector-based navigation, such as Dijkstra algorithm and Floyd algorithm, and grid-based navigation, such as A* algorithm. These three algorithms are briefly introduced below. [0003] 1. Dijkstra algorithm [0004] Dijkstra's algorithm belongs to traversal search and is the most classic path search algorithm. For a given sou...
