MULTI-PERSON SIMULTANEOUS LOCATION AND MAPPING (SLAM) LINKAGE POSITIONING AND NAVIGATION

摘要

Novel tools and techniques are provided for implementing multi-person SLAM linkage positioning and navigation for super large-scale scenes based on wireless signal characteristics and visual feature point information. In various embodiments, for creating a map model, a software application on a mobile device located in an area may generate or update a wireless signal fingerprint map model of the area based on signal data received from wireless signal sources within or near the area, may generate or update a visual feature point map model of a portion of the area based on image data received from visual sensors, and may send the wireless signal fingerprint map model and visual feature point map model to a remote computing system over a network. The remote computing system may analyze and integrate the wireless signal fingerprint map model and visual feature point map model to generate a global map of the area.
