METHOD AND SERVER FOR GENERATING SPATIAL MAP

Provided is a method, performed by a server, of providing a personalized spatial map, the method comprising: obtaining a first spatial map including first map features representing spatial information about a space; obtaining a second spatial map based on sensor data obtained by measuring the space, the second spatial map including second map features; identifying third map features for map alignment from among the first map features and the second map features; aligning the first spatial map and the second spatial map, based on the identified third map features; identifying local areas in the space where at least one difference exists between the first spatial map and the second spatial map; and generating the personalized spatial map by identifying pieces of spatial information about the local areas based on the second map features.
