Title:
NAVIGATION METHOD BASED ON THREE-DIMENSIONAL SCENE
Document Type and Number:
WIPO Patent Application WO/2016/179825
Kind Code:
A1
Abstract:
A navigation method based on a three-dimensional scene. The method comprises: calculating an interest value of a viewing angle of a camera based on a height, size, irregularity and uniqueness of a building in a scene (S101); and generating a track parameter of the camera according to the interest value of the viewing angle so as to perform navigation according to the track parameter (S102). The navigation method acquires a reasonable interest value of a viewing angle based on a height, size, irregularity and uniqueness of a building, thus realizing a high-quality navigation.
