Augmented reality display device and augmented reality display system

An augmented reality display device for displaying an augmented reality image, comprising:

• a display:
• an out-camera for capturing an image of a field of view of a user;
• a range sensor configured to measure a distance to each of a plurality of measurement points on a real object to be captured by the out-camera;
• and
• a processor connected to the display, the out-camera, and the range sensor, respectively, the processor being configured to:
• detect a type of the real object captured in a captured image generated by the out-camera,
• recognize a three-dimensional shape of the real object based on distance data to each of the measurement points detected by the range sensor,
• estimate a volume of the real object based on the three-dimensional shape of the real object,
• convert the volume of the real object to a mass based on a density of the real object, and use at least one of the mass or the volume of the real object as the physical quantity of the real object, and
• display, on the display, an augmented reality image indicating a physical quantity of the real object which is based on the volume,
• wherein the augmented reality display device further comprises an information input device configured to accept an input of a physical quantity indicating a required quantity of the real object,
• wherein the processor is further connected to the information input device, the processor further configured to:
• convert the physical quantity indicating the required quantity of the real object into a volume, and
• display, on the display, an augmented reality image configured with a reference marker, the reference marker indicating an area, which expresses the volume corresponding to the required quantity of the real object, of the three-dimensional shape, and
• wherein the reference marker is displayed at a position overlapping the real object on the display.
