| Summary: | 碩士 === 國立臺灣師範大學 === 機電科技研究所 === 99 === Blind people face many problems when they take bus. The major problem is to recognize an approaching city bus. The solution to this torment at present is to ask others’ assistance or to raise a sigh on which the destination is written for appealing bus drivers’ attention. But there exists much unreliability in fore-mentioned solutions. Because image processing is a highly developed research area, in this research, we adopt a mobile eyewear digital video to replace a traditional fixed one to help the blind recognize the bus numbers with vocal message. This research adopts proactive identification for fast response without harm to accuracy. Through beforehand analysis, a block with wanted colors is focused from input video. Then this data proceed with an adaptive binarization method for simplification and Morphology mask for integrity. Bus numbers can be obtained from the analysis with connected component and recognition of MS MODI. A vocal message will be launched with MS SAPI before bus stops in the end.
