Traditional barcode recognition equipments are very expensive and very often do not fit common users due to their large scale. A novel low-cost method is proposed in this paper to implement automatic recognition of the barcode information from images captured by a CMOS camera without the need for additional light source. Firstly, the barcode orientation is recognized based on the character of bar-like image. The barcode sequence is then generated by the image projection. Finally, the barcode information is recognized according to the encoding rule. The overall success rate is up to 90%, justified by 400 datasets provided by multiple individuals.
