Embodiment Construction
[0050] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0051]Since the subway is generally below the ground, users walk to the exit according to the guidance information in the subway station. When they walk out of the subway exit, they are prone to lack of sense of direction and cannot distinguish the direction of travel, so as to accurately arrive at the walking navigation route. To this end, the application discloses a method for determining navigation guidance information, which can provide navigation guidance information from a subw...

The invention discloses a navigation guidance information determining method and apparatus. The method comprises the following steps: for a pedestrian navigation route from a subway exit to the terminal point of walking, acquiring the terminal point of a guide line of a starting road section included in the pedestrian navigation route, with the subway exit as a starting point; acquiring the distance from the subway exit to the terminal point; and determining whether the distance is greater than a preset distance threshold, and if so, determining guidance information for walking from the subwayexit to the pedestrian navigation route according to the exit direction of the subway exit and the direction of the guide line. Since the orientation of a user walking out from a subway exit is generally the same as the exit direction of the subway exit, the purpose of determining guidance information based on the orientation of the user can be achieved according to the exit direction of the subway exit and the direction of the guide line; and thus, the user is assisted in correctly identifying an advancing direction at the subway exit and reaching the pedestrian navigation route.
Description
technical field [0001] The present application relates to the technical field of navigation, and more specifically, to a method and device for determining navigation guidance information. Background technique [0002] With the development of intelligent transportation, users can plan corresponding navigation routes (hereinafter referred to as routes) for different travel modes through map navigation software. Taking public transportation as an example, the implementation process generally includes: the client enters the origin and destination information and uploads it to the back-end server. The server plans the bus navigation route according to the start and end information, and the bus navigation route is composed of continuous road sections. The server not only determines the bus navigation route, but also determines the corresponding navigation guidance information (hereinafter referred to as the guidance information) for the sections included in the bus navigation rou...
