Portable display device with overlaid virtual information

A system for positioning a virtual object in an image of a scene including a real object, comprising:

• a portable device for inspection and service of a device of a transmission and/or distribution network;
• a short-range wireless transmitter arranged at a predetermined position relative to the real object;
• and
• a processing unit;
• wherein the portable device is configured to:
• acquire the image of the scene, and
• receive a signal from the short-range wireless transmitter;
• wherein the processing unit is configured to, based at least partially on directional information associated with the received signal, determine a location and orientation of the portable device relative to the short-range wireless transmitter;
• and
• wherein the portable device is further configured to:
• display the acquired image and the virtual object, and
• position the virtual object in the acquired image based at least partially on the determined location and orientation of the portable device relative to the short-range wireless transmitter and on the predetermined position of the short-range wireless transmitter relative to the real object.

A portable device for inspection and service of a device of a transmission and/or distribution network, comprising:

• an imaging device configured to acquire an image of a scene including a real object;
• and
• a display device configured to display the acquired image;
• wherein:
• the portable device is configured to receive a signal from a short-range wireless transmitter arranged at a predetermined position relative to the real object;
• the portable device is communicatively connected to a processing unit configured to, based at least partially on the received signal, determine a location and orientation of the portable device relative to the short-range wireless transmitter;
• and
• the display device is further configured to display a virtual object in the acquired image, wherein a position of the virtual object in the acquired image is based at least partially on the determined location and orientation of the portable device relative to the short-range wireless transmitter and on the predetermined position of the short-range wireless transmitter relative to the real object.

A non-transitory computer-readable medium having instructions stored thereon, wherein the instructions, when executed by a processor, cause the processor to:

• acquire an image of a scene by means of a portable device, the scene including a real object, the real object forming at least a part of a device of a transmission and/or distribution network;
• receive, at the portable device, a signal from a short-range wireless transmitter arranged at a predetermined position relative to the real object;
• determine, based at least partially on directional information associated with the received signal, a location and orientation of the portable device relative to the short-range wireless transmitter;
• display, on the portable device, the acquired image and the virtual object;
• and
• position, in the acquired image, the virtual object based at least partially on the determined location and orientation of the portable device relative to the short-range wireless transmitter and on the predetermined position of the short-range wireless transmitter relative to the real object.
