• indoor positioning
• quick response code (QR code)
• localization
• pattern matching
• plane model

Compared with other indoor positioning methods, pattern matching offers greater accuracy. However, its construction requires additional time and manpower cost, and larger positioning environments result in correspondingly greater construction costs and computing complexity. To reduce the cost and computing complexity of pattern construction, plane models featuring radio signals were adopted in conjunction with quick response codes to facilitate the simple and rapid construction of indoor environments in this study. The advantages of using plane equations instead of pattern matching radio maps for positioning computations include the following: (1) reducing the complexity of positioning computations; (2) eliminating the influences of positioning area size; and (3) providing reliable and accurate positioning with an average error of approximately 2.8 m.
