Display terminal, display control system and display control method

A display control system for display a virtual object on a display of a display terminal that is provided with the display, a color image camera configured to acquire a color image of a predetermined photographing range, and a distance image camera configured to acquire a distance image of the photographing range, the display control system comprising:

• a space recognition unit configured to use the color image and the distance image to generate a three-dimensional map of a structural object existing within the photographing range;
• a display data generation unit configured to generate display data in which a region of the virtual object behind the structural object in a line-of-sight direction is specified as a rear region, based on the three-dimensional map and real space placement position data of the virtual object to be displayed;
• and
• a display correction unit configured to correct the display data and display the display data as corrected on the display,
• the display correction unit being configured to correct the display data so as to display operation points of the rear region, and
• the operation points being points that accept an operation instruction with respect to the virtual object via the operation points.

A display control method of displaying a virtual object on a display of a display terminal that is provided with the display, a color image camera configured to acquire a color image of a predetermined photographing range, and a distance image camera configured to acquire a distance image of the photographing range, the display control method comprising the steps of:

• generating display data in which a region of the virtual object behind the structural object in a line-of-sight direction is specified as a rear region, based on a three-dimensional map of a structural object existing within the photographing range, which has been created in advance by using the color image and the distance image, and real space placement position data of the virtual object to be displayed;
• and
• correcting the display data so as to display operation points of the rear region, and
• the operation points being points that accept an operation instruction with respect to the virtual object via the operation points.
