Integrated Indoor Location System of QR Code and Its Application Based on Windows Phone

Quick Response (QR) Code is characterized by such features as large quantity of coding information, strong error correcting capability, low cost, etc. In this chapter, the scanning and recognition characteristics of QR code is tested on the basis of realization of indoor passive location system with Windows Phone operating system by taking advantage of the storage space information of QR code, and mutual restrictive relation between related variables, such as scanning deflection, scanning distance, size of QR code, etc. are studied with statistical method. In addition, the outdoor GPS location function and ordinary scanning function of QR code are integrated systematically, so that the outdoor GPS active location is combined to the indoor passive location of QR code, and the space information is combined to attribute information.
