Abstract
A method by a computing device obtains a digital image of a physical map, identifies features in the digital image, and obtains map augmentation information based on the identified features. The method then generates an augmented map based on the map augmentation information, and provides the augmented map for display. Related mobile devices and computer program products are disclosed.
Claims19
A method by a computing device, the method comprising:
- obtaining a digital image of a physical map;
- identifying features in the digital image;
- obtaining map augmentation information based on the identified features;
- generating an augmented map based on the map augmentation information;
- and
- providing the augmented map for display;
- wherein the method further comprises:
- determining a pose for an augmented reality (AR) image based on a pose of an AR headset and a pose of the physical map,
- wherein the generating of the augmented map comprises generating the AR image based on the augmentation information and the determined pose;
- and
- wherein the providing of the augmented map comprises providing the AR image to a see-through display screen of the AR headset for display with the determined pose on a see-through display screen for viewing by a user as an overlaid AR image on the physical map.
A computing device comprising:
- at least one processor;
- at least one memory connected to the at least one processor and storing program code that is executed by the at least one processor to perform operations to:
- obtain a digital image of a physical map;
- identify features in the digital image;
- obtain map augmentation information based on the identified features;
- determine a pose for an augmented reality (AR) image based on a pose of an AR headset and a pose of the physical map;
- generate an augmented map based on the map augmentation information and the determined pose;
- and
- provide the augmented map for display, wherein providing the augmented map for display comprises providing the AR image to a see-through display screen of the AR headset for display with the determined pose on a see-through display screen for viewing by a user as an overlaid AR image on the physical map.
A non-transitory computer readable medium storing program code executable by at least one processor of a computing device, the program code being configured to cause the at least one processor to perform operations comprising:
- obtaining a digital image of a physical map;
- identifying features in the digital image;
- obtaining map augmentation information based on the identified features;
- determining a pose for an augmented reality (AR) image based on a pose of an AR headset and a pose of the physical map;
- generating an augmented map based on the map augmentation information and the determined pose;
- and
- providing the augmented map for display, wherein providing the augmented map for display comprises providing the AR image to a see-through display screen of the AR headset for display with the determined pose on a see-through display screen for viewing by a user as an overlaid AR image on the physical map.
