Room model extraction device, room model extraction system, computer readable medium, and room model extraction method

A room model extraction system comprising:

• a room model requesting device;
• and a room model extraction device, wherein
• the room model requesting device includes:
• processing circuitry to transmit three-dimensional building data including a plurality of building components constituting a building having rooms and attribute information of each of the plurality of building components,
• the room model extraction device includes:
• another processing circuitry to receive the three-dimensional building data;
• and
• a memory to store the three-dimensional building data received by the processing circuitry;
• wherein the processing circuitry extracts a starting component, which is the building component to be a starting point, from the three-dimensional building data stored in the memory, searches for a plurality of building components adjacent to each other, with respect to the three-dimensional building data from which the starting component is extracted, by starting from the starting component, extracts a virtual room constituted by virtual members from the three-dimensional building data by placing a virtual member on each of a plurality of building components obtained as a search result,
• sets, for each of the virtual members in the virtual room, a piece of attribute information associated with the building component on which the virtual member is placed from among pieces of attribute information included in the three-dimensional building data, creates a virtual room, in which the pieces of attribute information are set, as a room model, and
• transmits the room model to the room model requesting device.
