Method and apparatus for creating virtual world

An apparatus for creating a virtual world, comprising:

• a processor;
• and
• a memory connected to the processor,
• wherein the memory stores program instructions executed by the processor to receive an image of a real space through a device having a stereo camera,
• collect mesh data for the real space and an object existing in the real space through the image,
• determine coordinates for first edges of the real space from the mesh data for the real space,
• select one of a plurality of second edges based on an area of a virtual space defined by each of the plurality of second edges facing a predetermined direction, when there are more first edges of the real space than edges of a polygon preset for the real space, and
• output a virtual space defined by some of the first edges and the selected one second edge and a virtual object corresponding to the object existing in the real space,
• wherein the apparatus is a head-mounted display, and
• the program instructions determine coordinates for the first edges by tracking a position of the head-mounted display in the real space through at least two tracking devices disposed in the real space,
• wherein in the program instructions, 3D initial coordinates of the head-mounted display are set as an origin point at the center in the real space, and a y-coordinate in the 3D initial coordinates is preset by a user,
• wherein a boundary of the real space is defined by x and z coordinates of at least some of the first edges of the real space based on the 3D initial coordinates,
• wherein each edge of the preset polygon is disposed in one of quadrants divided into x-axis and y-axis, and the x-axis and z-axis, and
• the program instructions calculate an area of a virtual space defined by each of the plurality of second edges positioned within a predetermined angular range on the same axis or the same quadrant, and select one second edge having the largest calculated area.
