Problems solved by technology

[0004] The AR application based on the 3D map system, in the prior art, generally superimposes the augmented reality information of the 3D map system on the real scene through the latitude and longitude position of the real scene and the horizontal direction of the virtual camera of the 3D map system. However, due to The corresponding relationship between the 3D map system and the real scene is very complicated. Only considering the above factors, the 3D map system and the real scene cannot be accurately matched, resulting in inaccurate positions where the information of the 3D map system is superimposed on the existing objects in the real scene. Unable to bring users a good user experience

Abstract

The invention discloses a method and device for achieving augmented reality based on a three-dimensional map system. The accuracy of the overlapping position of the information of the three-dimensional map system and existence in a reality scene is improved. The method for achieving the augmented reality based on the three-dimensional map system comprises the steps of acquiring the direction parameter of the actually-measured geographic position of a mobile terminal camera, converting the direction parameter of the actually-measured geographic position into the geographic position direction parameter under the coordinate system of the three-dimensional map system, calling a vision cone perspective parameter obtained based on the actually-measured imaging parameter of the mobile terminal camera and the geographic position direction parameter, and displaying augmented reality information in the three-dimensional map system.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for realizing augmented reality based on a three-dimensional map system. Background technique [0002] Augmented reality (AR, Augmented Reality) is a technology that uses virtual objects to enhance the reality of real scenes. Augmented reality retains the user's actual environment as the user's main perception and interaction environment, and marks the virtual generated information such as text, two-dimensional graphics, and three-dimensional models on the objects displayed on the display screen in the user's actual environment. , so as to realize the annotation and description of the user's environment, or the effect of augmenting the reality environment. For example, if a user wears special augmented reality display glasses and visits a museum in person, when viewing a certain cultural relic, he can not only see the cultural relic and its sur...
