A Survey and Application of Indoor Positioning Based on Scene Classification Optimization

At present, outdoor positioning technology is being widely used, the wireless indoor positioning technology is becoming a research highlight in recent years. But due to the diversity of the indoor environment of the building structure and the complexity of the signal propagation, its application effect is not ideal. In this paper, the indoor positioning scenes are subdivided into three categories on the basis of detailed analysis of common architectural scenes in indoor positioning applications. Then, the corresponding optimization is carried out for different indoor positioning scenarios from those aspects such as wireless positioning method, the localization algorithm and deployment skills, which improved the practicability and applicability of wireless indoor positioning systems. The deployment process is described based on the indoor positioning application of the hospital. At the end of the paper, the scope of application and limitations of the scene classification optimization are summarized and the research direction in the future is clarified.
