Augmented reality system

1. Augmented reality system, comprising:

an unmanned moving object;

an augmented reality marker arranged on or within said unmanned moving object, the augmented reality marker being used for identifying an image associated with the augmented reality marker;

processing circuitry configured to

receive an image of a real environment including the unmanned moving object;

detect the augmented reality marker arranged on or within said unmanned moving object based on the received image;

identify the image associated with the augmented reality marker based on the detected augmented reality marker;

map the determined image associated with the augmented reality marker on the unmanned moving object;

generate an overlaid image by overlaying the mapped image on the unmanned moving object in the received image of the real environment; and

output the generated overlaid image to a display, wherein

the unmanned moving object is an unmanned flying object,

the unmanned flying object is a blimp comprising a gas-filled envelope,

the gas-filled envelope has an outer surface, and

the processing circuitry is configured to map said image associated with the augmented reality marker on the entire outer surface of the gas-filled envelope.
