Identification information generation method and apparatus for virtual space

A method of generating identification information for a virtual space, the method comprising:

• setting a plurality of crawling points for each crawling area in a three-dimensional virtual grid shape for a virtual space;
• collecting at least one of a street view image and an aerial view image in a preset direction at the crawling point;
• and
• generating a spatial descriptor for each of the crawling points from the collected image,
• wherein the collecting of the at least one of the street view image and the aerial view images includes:
• connecting images captured in 360 degrees in all directions using a virtual drone to generate the aerial view image in a form of a panoramic image;
• and
• connecting images captured in 360 degrees in all directions using a virtual mobile robot to generate the street view image in a form of a panoramic image.

• wherein the generating of the spatial descriptor includes converting the collected image into a depth image and generating a spatial descriptor for each of the crawling points from the depth image.
