Path navigation method and device based on path direction locking

Abstract

The invention discloses a path navigation method and a path navigation device based on path direction locking. The path navigation method comprises the steps of: acquiring a navigation path which comprises a plurality of sub-paths, and enabling each sub-path to correspond to one path direction; calculating an included angle between the path direction of the sub-path where a user is located and theorientation of the user to obtain a first included angle, and judging whether navigation equipment is in a path direction locking mode; if the navigation equipment is not in the path direction locking mode and the first included angle is smaller than a first threshold value, controlling the navigation equipment to enter the path direction locking mode to perform path navigation; and if the navigation equipment is in the path direction locking mode and the first included angle is greater than a second threshold value, controlling the navigation equipment to switch to a mode of rotating a map along with people, and carrying out path navigation. By implementing the path navigation method and the path navigation device of the invention, the problem of deviation between a user advancing path displayed on the map and an actual advancing path of the user due to the error of the compass sensor in the navigation equipment in the existing navigation technology can be solved.

Description

technical field [0001] The present invention relates to the technical field of route navigation, in particular to a method and device for route navigation based on route direction locking. Background technique [0002] Existing mobile phone navigation software has two modes in map presentation, one is the north mode, and the other is the map follower mode. In the north mode, the direction of the map will be fixed to the north. When the user views the map, dragging up, down, left, and right can easily correspond to which direction the map is dragging. The map rotation mode takes the user's location as the center of the map, and uses the user's orientation (that is, the orientation of the navigation device) as the direction of map rotation. For example, when the user is facing east, the map will rotate to the right with the user's location as the center. 90 degrees, with east facing forward. When the user faces south, the map will rotate 180 degrees around the user's positio...
