Precise Indoor Pressure Positioning System Based on LabVIEW

Using a single positioning technology for indoor positioning systems may cause drawbacks, such as low robustness, low positioning accuracy, and long response time, therefore, a four-point pressure location model is proposed in this paper. Furthermore, we designed an indoor pressure positioning system using LabVIEW, Bluetooth, data acquisition card, Solid Works, and a 3D Printer to perform a simulation, and solved the problem of locating the blind-area in this model. The comprehensive application of various positioning technologies and the consideration in locating the blind-area resulted in precise positioning. Our experimental results show that the absolute error of the indoor positioning system is within 1 cm.We proposed an accurate and easy to operate indoor positioning method, which makes up for the lack of indoor positioning in accuracy, practicality, and price.
