1. A server that provides virtual indoor space content corresponding to a real indoor space, the server comprising:
a memory;
a communication module; and
at least one processor operatively connected to the memory and the communication module,
wherein the at least one processor receives image data to generate the virtual indoor space content from a mobile terminal through the communication module, the image data including, for each of a plurality of indoor points, an omnidirectional image acquired from each indoor point and relative location information on the indoor point including a relative movement path from a previous indoor point to the indoor point, and
generates the virtual indoor space content by mapping a plurality of virtual points corresponding to the plurality of indoor points in a virtual indoor space based on the relative location information,
wherein the at least one processor generates the relative location information by verifying a visual movement information obtained using an inertial movement information.
