Method for generating space map including actual image by using image obtained by photographing space, and electronic device for performing same

A non-transitory computer-readable recording medium having recorded thereon a program including instructions that, when executed by at least one processor of an electronic device, cause the electronic device to perform a method comprising:

• obtaining an initial map of a target space;
• obtaining a captured image of at least one area of interest in the target space;
• based on depth information included in the captured image, registering an actual image to the initial map, the actual image being obtained from the captured image;
• determining a generation required area for which image generation is required in the initial map to which the actual image is registered;
• and
• generating, by using a generative model, an actual map by generating an image for the generation required area.

An electronic device for generating a spatial map, the electronic device comprising:

• memory storing instructions;
• and
• at least one processor,
• wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
• obtain an initial map for a target space,
• obtain a captured image of at least one area of interest in the target space,
• register, based on depth information included in the captured image, an actual image to the initial map, the actual image being obtained from the captured image,
• determine a generation required area for which image generation is required in the initial map to which the actual image is registered, and
• generate, by using a generative model, an actual map by generating an image for the generation required area.
