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.

System and method for active data collection mode control for reducing crowd-sourcing signal data collection required for fingerprint database maintenance

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.
