| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士在職專班 === 96 === This thesis presents a QR code audio guider. It is composed of image capture, image processing, error correction, information decoding, audio link. In addition to overview of QR code, encoding, CMOS sensor characteristics, mainly in Sunplus 16-bit microprocessor SPEC061A to achieve QR code of the decoder. The main advantage is that the C language code of cross-platform, and to reduce external components.
Sunplus 16-bit microprocessor to achieve SPEC061A QR code decoder can be divided into five parts, the first to write commend through SCCB bus to the CMOS sensor registers, the second control external memory, the third part from the CMOS sensor to read out information to the microprocessor, the fourth part from the microprocessor to transmit data to personal computers, as part of the fifth on a personal computer QR code decoding software to verify the results are correct.
We printed images of various sizes, and then using the platform to capture image, the QCIF decoding software to verify the decoding. The platform can capture the image more than 1.2 X1.2 cm above and decode correctly.
