Displaying method of path across floors based on indoor map application

Abstract

The invention discloses a displaying method of a path across floors based on an indoor map application. The method comprises the following steps that an indoor map is made: a vector map data editing tool or a three-dimensional modeling tool is used, or a grid map and graph processing tool is directly used to carry out processing and making; each made floor plan graph carries out map output as a fixed depression angle and the maps are superposed into one graph; if there are too many floors, a compression and merging mode can be used to carry out displaying according to a need; unfolding is performed when it is necessary so that many redundant displaying effects are avoided; when indoor path planning and navigation are needed to be performed, firstly a formation route is calculated, and then intuitive and effective displaying is performed on the formation route; all the floors can be displayed, and floors at a starting point and an end point and intermediate floors can be displayed too; if partial displaying of the intermediate floors is similar, compression or merging displaying can be performed according to a need; the path in one floor is displayed in a line mode and the path across the floors is displayed as a stereogram of a stair, an escalator and an elevator or a vivid sketch map or an animation effect mode through superposing on the map; a path form used during floor transition in the displaying of the path across floors is visually showed so that complete and vivid map path displaying is formed.

Description

technical field [0001] The invention belongs to the field of indoor map navigation and path planning, in particular to a method for displaying cross-floor paths based on indoor map applications. Background technique [0002] At present, cross-floor path planning and navigation based on indoor maps are not widely used. In the relevant applications and researches currently available, the specific display process of indoor navigation is generally as follows: (1) display complete path text description information, (2) Only the driving path in one floor and the location of the nodes on the upper and lower floors are displayed. (3) When you need to see other floors or navigate to the nodes on the upper and lower floors and complete the action of going up (down) the floor, the map is refreshed and switched to another floor map, (4) repeat the above process until the end of the viewing path or travel to the destination.

Problems solved by technology

[0003] see figure 1 , in the implementation technology of cross-floor path planning and navigation based on indoor maps, there is one biggest shortcoming, that is, in the process of cross-floor path display, users cannot intuitively see the complete walking route

In the current screen field of view, only one floor map and the walking route on the current flo
