A relative position of a moving node is estimated based on motion sensing of the moving node, the relative position of the moving node is corrected based on a comparison between a change pattern of at least one signal strength received over a plurality of time points and a signal strength distribution in a region in which the moving node is located, a route of the region is represented by using the relative position corrected as described above, and thereby, it is possible accurately estimate a position of the moving node and to create a map in which very accurate route information is recorded throughout the entire region at the same time, even if a wireless environment change such as signal interference between communication channels, expansion of an access point, and occurrence of a failure or an obstacle is made or a poor wireless environment such as lack of the number of access points occurs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Slam method and apparatus robust to wireless environment change","description":"The present invention relates to SLAM (simultaneous localization and mapping) method and apparatus robust to a wireless environment change.
