Embodiment Construction

[0019] Attached below figure 1 The specific embodiment of the present invention will be described in further detail.

[0020] figure 1 The method for customizing and displaying a real-scene three-dimensional map navigation route implementing the present invention is shown, and the method includes the following steps:

[0021] Step 101: The server sets nodes on the roads of the real-scene 3D map, and generates a first video representing all real-scene images between two adjacent nodes based on the perspective of pedestrians, thereby forming a representation of each adjacent node in the server database. A plurality of first videos of real scene video images; the nodes include important geographical coordinates, road intersections and nodes arranged at predetermined distances; the first videos are processed into second videos with lower image quality; the first videos 1. The image displayed in each frame of the second video corresponds to the geographic location corresponding t...

Abstract

A method for customizing and displaying a navigation route of a live-action three-dimensional map comprises the following steps: a server sets nodes in roads of a live-action three-dimensional map, generates first videos representing live-action images between two adjacent nodes based on a visual angle of pedestrian advancing, and processes the first videos into second videos with relatively low image quality; when a user finds a plurality of positions of interest when browsing the live-action three-dimensional map, the user enters a route-of-interest description mode to draw a first route containing the plurality of positions of interest on the live-action three-dimensional map in a finger sliding mode; a node route including the first route is further obtained; and one or more second videos corresponding to the node route are played based on the visual angle of pedestrian advancing. The method has the advantage that the information of the whole travel route is completely displayed to the user based on the visual angle of pedestrian advancing, and the method also has a route-of-interest description mode, so that an expected route can be intuitively and conveniently obtained.

Description

technical field [0001] The invention relates to the field of real-scene three-dimensional maps, in particular to a method for customizing and displaying a real-scene three-dimensional map navigation route. Background technique [0002] The real-scene 3D map uses satellite or laser technology to directly scan the height and width of the building, and finally forms a 3D map data file. The real-scene 3D map is realized based on physical shooting and data abstraction collection technology. [0003] When using the real-scene 3D map, the inventor found that although the real-scene 3D map has a high degree of realism and strong visibility, it usually does not provide a browsing method based on the user’s traveling perspective, nor can the entire article be displayed based on the user’s traveling perspective. All images of the route information are presented to the user. [0004] Moreover, when the user browses the real-scene 3D map, since the distribution characteristics of the su...
