Abstract

Abstract: In this paper, we mainly study the triangle positioning method based on WiFi signal indoor positioning technology, in view of the existing model by triangle positioning signal strength and environmental interference, the positioning accuracy is not high, this paper proposes a weight correction model, which is based on the constraints of indoor influence factors. Through the experimental test and data analysis, the accuracy of the corrected model is higher and the applicability is wider.

Key words: indoor localization technology, WiFi positioning, triangle positioning, positioning accuracy, computational model

CLC Number:
