A Kind of Automatic Banknote Sorting Device Based on Vision

In recent years, banknote classification has been a hot topic, and a series of mechatronic devices have been born on the market. Under this background, this paper, based on the vision, provides a banknote sorting device. This device first uses the industrial cameras to take pictures of flattened banknotes, then reads the banknotes images through VC ++ 6.0 and processes the images accordingly, finally identifies the denomination of the banknotes and makes mechanical classification of the banknotes. This paper begins with three parts, image acquisition, image processing and banknote classification. In order to facilitate development, the image acquisition utilizes an industrial camera with an SDK. Using advanced digital image processing technology, the banknotes image denoising, smoothing, sharpening, binarization and other processing, and the paper currency boundary was calculated to achieve the realization of banknotes intelligent identification with different denominations. The classification of the banknote mainly introduces the hardware and classification principle of the device, and theoretically realizes the automatic classification of different denominations.
