Method for Representing Virtual Information in a Real Environment

摘要

A method for representing virtual information in a view of a real environment is provided that includes: providing a system setup including at least one display device, wherein the system setup is adapted for blending in virtual information on the display device in at least part of the view, determining a position and orientation of a viewing point relative to at least one component of the real environment, providing a geometry model of the real environment, providing at least one item of virtual information and a position of the at least one item of virtual information, determining whether the position of the item of virtual information is inside a 2D or 3D geometrical shape, determining a criterion which is indicative of whether the built-in real object is at least partially visible or non-visible in the view of the real environment, and blending in the at least one item of virtual information on the display device in at least part of the view of the real environment.

1. A method for representing virtual information in a view of a real environment, comprising the following steps:
providing a system setup comprising at least one display device, wherein the system setup is adapted for blending in virtual information on the display device in at least part of the view; determining a position and orientation of a viewing point relative to at least one component of the real environment; providing a geometry model of the real environment, the geometry model comprising at least one representation of at least one built-in real object of the real environment, wherein the representation of the built-in real object comprises at least one 2D or 3D geometrical shape having at least one boundary for delimiting the object; providing at least one item of virtual information and a position of the at least one item of virtual information; determining whether the position of the item of virtual information is inside the 2D or 3D geometrical shape and associating the item of virtual information with the built-in real object if it is determined that the item of virtual information is inside the 2D or 3D geometrical shape; determining a criterion which is indicative of whether the built-in real object is at least partially visible or non-visible in the view of the real environment calculated by using the geometry model and the position and orientation of the viewing point; and blending in the at least one item of virtual information, which is associated with the built-in real object, on the display device in at least part of the view of the real environment depending on the criterion; wherein the virtual information is shown differently in case the criterion indicates that the built-in real object is at least partially visible than in a case the criterion indicates that the built-in real object is non-visible in the view of the real environment.
