Claim:
1. A method for extracting outer space feature information of an indoor space structure from spatial geometric data, the method comprising: performing, by an electronic device, an input step of inputting spatial geometric data for a target region; performing, by an electronic device, a sampling step of determining a sample by selecting a crossing area where the spatial geometric data input in the input step and a crossing plane cross each other; and performing, by an electronic device, a feature extraction step of acquiring outer space feature information of the indoor space structure for a corresponding sampling plane using a convex hull method based on sampling information including sampling plane information of the spatial geometric data for a sampling plane selected in the sampling step; wherein the sampling plane is selected as the crossing plane defining the crossing area with the spatial geometric data.
