Embodiment Construction
[0048] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0049] The gist of the present invention is that through the analysis of the existing banknote discrimination requirements, especially the high-speed discrimination requirements without collecting banknote images, it is found that the existing banknote discrimination usually needs to obtain a complete banknote image before performing discrimination processing, so that the banknote discrimination To solve the problem of slow processing speed, the present invention provides a high-speed banknote discrimination system and its discrimination method based on partial image sub-blocks to solve the above problems.
[0050] see figure 1 , the high-speed banknote discrimination system based on partial image sub-blocks of the present invention includes three basic ...

The invention provides a high speed note distinguishing system and method based on partial image sub blocks to solve the problem of low note distinguishing treatment speed caused by the fact that the existing note distinguishing treatment must be conducted by using a complete note image. The note image is divided into the plurality of image sub blocks, a note distinguishing process is divided into a plurality of sub processes, one distinguishing sub process is executed to finish a part of calculation tasks each time an image sub block is received, and surplus calculation tasks are executed when all the image sub blocks required by distinguishing are received to obtain a distinguishing result. A note scanning process and a distinguishing calculation process are conducted simultaneously, calculation resources are fully utilized, and treatment time is reduced.
Description
technical field [0001] The present invention relates to the related technical field of banknote processing, in particular to a high-speed banknote discrimination system and a discrimination method based on partial image sub-blocks. Background technique [0002] In cash ATMs, sorting machines, and banknote counters, there are devices that use image processing to identify banknotes, mainly including banknote currency, face value, orientation, authenticity, incompleteness, staining, old and new identification, etc. Before identifying banknotes, the image should be preprocessed to calculate banknote boundaries, positions, inclinations, etc. [0003] In the current processing method, the entire banknote is scanned and processed after the complete banknote image is obtained. This makes it necessary to perform complex processing on the image after the scanning is completed, so as to obtain the discrimination result and determine which port the banknote will be delivered through. ...
