Problems solved by technology

Although this method can improve the positioning accuracy to a certain extent, its shortcomings are also obvious. This method mainly maps the source domain and the target domain to the subspace by learning a shallow mapping, and the shallow mapping can only learn shallow Layer representation features, which are clearly insufficient for reducing domain variance
Therefore, due to the existence of the above problems, it is difficult for this type of method to form accurate, real-time and stable positioning in complex indoor environments.

Abstract

The invention belongs to the category of solving the RSS volatility problem by adopting a deep transfer learning method in a complex indoor environment. The indoor positioning method based on the deepadaptive network is characterized by comprising the following steps: 1, dividing an indoor environment needing to be positioned into grid point areas with the same size, and recording corresponding coordinate information; 2, sequentially placing the mobile device at each grid point in the positioning environment, and recording RSS values from each access point and corresponding grid point coordinate information at the moment to form an RSS offline fingerprint database, namely a source domain; 3, collecting an RSS value of the to-be-positioned mobile device to form a target domain; 4, realizing knowledge migration; and step 5, inputting the target domain data into the trained network to obtain the position.

Description

technical field [0001] The invention belongs to a method for positioning by using received signal strength in an indoor environment, in particular a technology for positioning a wireless device in a complex indoor environment by using a deep transfer learning method, specifically an indoor positioning method based on a deep self-adaptive network. Background technique [0002] In recent years, due to the wide application of mobile devices and the rapid development of social networks, the demand for indoor positioning services is increasing. For example, navigation in large airports and stations, real-time monitoring of workers' positions in factories, and rescue of indoor personnel in emergency situations are too numerous to mention. Therefore, under the influence of huge market traction, seeking a high-precision real-time positioning system suitable for complex indoor positioning environments has become the research focus of the industry. [0003] Generally, the WiFi-based ...
