A method for providing an augmented reality display on a mobile device

摘要

A method for providing an augmented reality display on a mobile device having viewing optics (22) which defines a perspective view of a user, the method comprising the steps of: (a) sampling an image from an image sensor (32) deployed in fixed spatial relation to viewing optics (22) of the mobile device; (b) obtaining a registration mapping between the perspective view of the user and a geographic coordinate system, said registration mapping being derived at least in part by registering said sampled image with at least one location reference tied to the geographic coordinate system, said at least one location reference including an elevation map or three dimensional model; and (c) displaying to the user information about a point of interest in the context of the perspective view of the user, said information being displayed in spatial alignment with the point of interest derived from a geographical location of the point of interest together with said registration mapping.
