[0034] figure 1 A flow chart of the edge fitting method provided by the embodiment of the present invention is shown. refer to figure 1 , the method includes:

[0035] Step S1: Collect images of banknotes to be inspected.

[0036] After the user inserts the banknotes into the banknote checking device, the image of the banknotes to be checked is collected by the camera of the banknote checking device.

[0037] Step S2: Obtain a plurality of edge points corresponding to the first edge of the banknote to be inspected based on the image detection.

[0038] The banknote checking device uses a preset edge detection algorithm to process the image of the banknote to be checked to obtain a plurality of edge points corresponding to the edge of the banknote to be checked. Wherein, the preset edge detection algorithm may adopt an edge detection algorithm in the prior art. Since the edge fitting method provided by the embodiment of the present invention is similar to the processing st...

Abstract

The invention relates to the technical field of banknote detecting, and provides an edge fitting method and a currency detector. According to the edge fitting method, firstly, an image of the banknoteto be inspected is collected and then detected to obtain a plurality of edge points corresponding to a first edge of the banknote to be inspected. Then, the distance value of any two adjacent edge points of a plurality of edge points in the first quadrant of the image is calculated. Then, at least one of the obtained distance values is counted as a distribution histogram. According to the distribution histogram, at least two edge points to be fitted in the edge points are selected. Finally, a first straight line used for representing the first edge is fitted based on the selected edge pointsto be fitted. The edge fitting method has the advantages of being simple in process and high in execution efficiency. Currency detectors applying the edge fitting method can quickly complete the checking work of banknotes. Besides, the currency detectors are suitable for checking a large number of banknotes in a short time.

Description

technical field [0001] The invention relates to the technical field of banknote inspection, in particular to an edge fitting method and banknote inspection equipment. Background technique [0002] At present, when checking the authenticity of banknotes, a mainstream technical solution is: when the user puts the banknotes to be checked into the banknote checking device, the banknote checking device first collects the image of the banknote to be checked, and then recognizes the banknote based on the image. Some image features of banknotes to be inspected, and finally compare these image features with the preset image features in the banknote inspection device to identify the authenticity of the banknotes, wherein the preset image features are the image features of genuine banknotes stipulated by the state. In the above banknote inspection steps, the banknote image collected by the banknote inspection equipment is the basis of the subsequent inspection steps, and its importance...
