Navigation path planning method and device, navigation terminal and storage medium

Abstract

The invention relates to a navigation path planning method and device, a navigation terminal and a storage medium. The method comprises the steps of acquiring an avoidance area; obtaining an originalnavigation path between a starting position and an ending position; if it is detected that an intersection is generated between the original navigation path and the avoidance area, determining the position of a splitting point, the position of the splitting point being obtained by the intersection; determining a split road section which is connected between the starting position and the splittingpoint position; determining an avoidance road section which is connected between the splitting point position and the ending position; determining a new split road section and a new avoidance road section according to the intersection condition of the avoidance road section and the avoidance area until the determined avoidance road section and the avoidance area have no intersection; and collecting the split road section and the avoidance road section to obtain an avoidance navigation path between the starting position and the ending position. By adopting the method, the navigation terminal can automatically detect and plan a path, so that a user can be away from an emergency in time, and the personal and property safety is prevented from being endangered by the emergency.

Description

technical field [0001] The present application relates to the technical field of navigation, in particular to a navigation route planning method, device, navigation terminal and storage medium. Background technique [0002] Electronic map, that is, digital map, is a map that is stored and consulted digitally using computer technology. [0003] At present, when users encounter natural disasters or man-made terrorist attacks such as earthquakes, waterlogging, rainstorms or typhoons, it is difficult to plan safe evacuation routes for users in time due to the single patterns and functions displayed on the electronic map. Necessary waste of time, and even endanger the user's personal and property safety. Contents of the invention [0004] Based on this, it is necessary to provide a navigation route planning method, device, navigation terminal and storage medium for the above technical problems. [0005] On the one hand, an embodiment of the present invention provides a naviga...
