A Location Estimating Method of Buried Victims in Collapsing Area Using Wi-Fi Signals
ICVISP 2018: Proceedings of the 2nd International Conference on Vision, Image and Signal ProcessingAugust 2018, Article No.: 49, Pages 1–5https://doi.org/10.1145/3271553.3275240When urban areas are hit by a disaster such as an earthquake, subway and tunnel-collapsing causes severe damages to both people and property. Especially it requires a lot of manpower and time to rescue the buried persons in the scene of accident. ...

WLAN-based Location Monitoring System in Confined Workspaces
ICVISP 2018: Proceedings of the 2nd International Conference on Vision, Image and Signal ProcessingAugust 2018, Article No.: 48, Pages 1–5https://doi.org/10.1145/3271553.3271621In confined work sites such as mines and ships, it is important to monitor the worker's current location for safety. When the collapse or sinking accident occurs, quick rescue can be realized based on the location of the workers. However, it is not easy ...

Estimating AP Location Using Crowdsourced Wi-Fi Fingerprints with Inaccurate Location Labels
ICVISP 2018: Proceedings of the 2nd International Conference on Vision, Image and Signal ProcessingAugust 2018, Article No.: 45, Pages 1–6https://doi.org/10.1145/3271553.3271582The fundamental property of Wi-Fi signals for Wi-Fi positioning is that the signal strength of radio signals decreases as radio signals propagate. Since access points (APs) are sources of each Wi-Fi signal, knowing AP locations can help to exploit Wi-Fi ...

An LSTM-based Indoor Positioning Method Using Wi-Fi Signals
ICVISP 2018: Proceedings of the 2nd International Conference on Vision, Image and Signal ProcessingAugust 2018, Article No.: 43, Pages 1–5https://doi.org/10.1145/3271553.3271566Recently, Wi-Fi fingerprints are often used for constructing indoor positioning systems. Wi-Fi fingerprint is a vector of Received Signal Strength (RSS) values at a particular location. Radio map is the collection of Wi-Fi fingerprints and their ...
