摘要： Provided is an atypical environment-based location recognition apparatus. The apparatus includes a sensing information acquisition unit configured to, from sensing data collected by sensor modules, detect object location information and semantic label information of a video image and detect an event in the video image; a walk navigation information provision unit configured to acquire user movement information; a metric map generation module configured to generate a video odometric map using sensing data collected through a sensing information acquisition unit and reflect the semantic label information; and a topology map generation module configured to generate a topology node using sensing data acquired through the sensing information acquisition unit and update the topology node through the collected user movement information.

摘要： An active data collection mode control system to reduce crowd sourcing signal data collection required for fingerprint database (FPDB) maintenance is provided. The system includes a mobile device that supports a survey mode, a localization mode, and a crowd-sourcing mode, and a server that receives data from the mobile device, generates and updates an FPDB, and controls a data collection mode.
