Passive WiFi localization works by capturing and analyzing the signals that reflected from human body without any devices attached to human. Although physical model has been built in former research to get relationship between signal and location, it requires accurate measurement of WiFi antenna set up. Parameters like angle-of arrival(AoA) and time-of-flight(ToF) are impossible to be estimated accurately in some cases. This paper presents a device-free WiFi localization system, which uses a combination of physical model and deep learning method to estimate human location. Firstly, compare to traditional AoA and ToF estimation, we propose a modified signal profile inherits the spirit of AoA ToF profile but overcomes the limit of accurate measurement of antenna distance. Then, we create Gaussian distribution image based on these signal profile and use deep learning to learn the relationship between the profile and ground truth location. Our system achieves accurate human localization without knowledge of accurate deployment of the WiFi system.
