Abstract

The invention relates to the technical field of banknote inspection and provides an edge detection method and a money detector. The edge detection method comprises the steps of collecting an image ofa banknote to be inspected, determining at least two to-be-detected columns and at least one to-be-detected row of a first edge of the banknote to be inspected in the collected image, further determining intersections of each to-be-detected row in the at least one to-be-detected row and the at least two to-be-detected columns to be a to-be-detected pixel point set on the above basis, then detecting and obtaining at least two edge points based on the at least one to-be-detected pixel point set, and finally carrying out fitting to obtain a first straight line for characterizing a first edge based on the at least two edge points. The edge detection method has the advantages of simple steps, a small amount of calculation and high execution efficiency. The money detector with the application ofthe edge detection method can quickly complete the inspection of banknotes and is suitable for inspecting 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 detection 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 importan...
