Research of the Three-Dimensional Spatial Orientation for Non-visible Area Based on RSSI
摘要
This paper research the stereo space location of invisible areas based on RSSI. Introduce the basic knowledge of RSSI and spatial positioning, and analyze the related existing technologies. On the basis of distance correction, this correction model converts the RSSI value of the unknown Wi-Fi direct connected device into a number which delegates the distance. Then constructs the relative spatial position by combination the geometric principle, so as to compute the location of the node. The unknown Wi-Fi direct connected device receives information from the three known Wi-Fi direct connected devices. The positioning application of this ranging correction model is widely used.
