In order to calculate an actual distance between coordinates in an image, a regular image for an original image may be generated based on an intrinsic parameter of a camera and pose information of the camera, based on first coordinates in the regular image that are received, first world coordinates corresponding to the first coordinates may be calculated in a world coordinate system, based on second coordinates in the regular image that are received, second world coordinates corresponding to the second coordinates may be calculated in the world coordinate system, and a distance between the first world coordinates and the second coordinates may be calculated.

Method and apparatus for calculating actual distance between coordinates in image

In order to output an image to a user, an electronic device may include loading a plurality of basic image tiles with a first resolution, the plurality of basic image tiles being preset for a graphic space set based on a virtual coordinate system, determining a target basic-image tile among the plurality of basic image tiles based on a coordinate of a virtual camera set on the virtual coordinate system, transmitting information on a target basic-image tile to a server, receiving a plurality of detailed image tiles with a second resolution corresponding to the target basic-image tile from the server, and outputting an image with the second resolution based on the plurality of detailed image tiles when the virtual camera zooms in on the target basic-image tile.

Method and device for outputting an image

Provided is a system and method for providing a virtual space tour, the system including: a plurality of user terminals; and a server configured to provide a virtual space corresponding to a real indoor space to the plurality of user terminals, to receive a plurality of pieces of motion data from the user terminals, to generate a plurality of motion objects corresponding to the plurality of pieces of motion data, and to generate user's tour information based on the plurality of pieces of motion data, wherein the virtual space includes 360-degree images provided at a plurality of points in the real indoor space, and the plurality of user terminals configured to be independently operated in the virtual space at a same point or different points based on the virtual space and individually generate motion data in response to a user manipulation input.
