Embodiment 1

[0064] The banknote authenticity identification device based on number extraction provided by Embodiment 1 of the present invention is provided with two sets of number extraction devices only on one side of the transmission channel 10. In this embodiment, it is set above the transmission channel as an example. Its structure is as follows figure 2 As shown, it includes: number extracting device (11a, 11b, 12a, 12b), number identifying device 21 and authenticity judging device 31.

[0065] Wherein, number extracting device 11a and 11b are a group, number extracting device 12a and 12b are a group, two groups of number extracting devices are arranged on the top of transmission channel altogether, for figure 1 Number field settings for banknote 20 face up shown in . When only two sets of number extraction devices are set on one side of the transmission channel, the number extraction device will obtain the specified number area when the banknote passes through the designated colle...

Embodiment 2

[0070] In the banknote authenticity identification device based on number extraction provided in Embodiment 2 of the present invention, two sets of number extraction devices are only provided on one side of the transmission channel 10, which is different from the first embodiment in that it is installed below the transmission channel. For example, its structure is as image 3 As shown, it includes: number extracting device (13a, 13b, 14a, 14b), number identifying device 21 and authenticity judging device 31.

[0071] Wherein, number extracting device 13a and 13b are a group, number extracting device 14a and 14b are a group, two groups of number extracting devices are arranged in the below of transmission channel altogether, for figure 1 Number field settings for banknote 20 reverse side up shown in . When only two sets of number extraction devices are set on one side of the transmission channel, the number extraction device will obtain the specified number area when the bank...

Embodiment 3

[0075] The banknote authenticity identification device based on number extraction provided by Embodiment 3 of the present invention, when two sets of number extraction devices are installed on both sides of the same collection position of the transmission channel, when the banknote passes through the designated collection position of the transmission channel, the specified number area is obtained number image. Its structure is as Figure 4 As shown, it includes: number extraction device (11a, 11b, 12a, 12b, 13a, 13b, 14a, 14b), number identification device 21 and authenticity determination device 31.

[0076] Number extraction device 11a and 11b are a group, number extraction device 12a and 12b are a group, are arranged on the top of transmission channel; Number extraction device 13a and 13b are a group, number extraction device 14a and 14b are a group, are arranged on the transmission channel below the channel.

[0077] In this embodiment, each group of number extraction de...

Abstract

The invention discloses banknote authenticity identification equipment based on number extraction and a method thereof. The banknote authenticity identification equipment comprises the components of two sets of number extraction devices which are arranged for aiming at a preset number area on at least one side of a banknote conveying channel, wherein the number extraction devices are used for acquiring the number image of the preset number area when the banknote passes a preset acquisition position of the banknote conveying channel; a number identification device which is used for identifyingthe number in the number image; and an authenticity determining device which is used for acquiring the identified number, determines whether the numbers which are extracted by the number extraction devices are same and whether the identified numbers are the number of true banknote, and determines authenticity of the banknote according to a determining result. Through arranging the number extracting devices at the position of the area which corresponds with the banknote number, total scanning is prevented, data processing amount is reduced, and furthermore identification precision and identification accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of banknote anti-counterfeiting detection, and in particular relates to a banknote authenticity identification device and method based on number extraction. Background technique [0002] The serial number (or number, prefix code) on the banknote is the unique sign that identifies the identity of a single banknote. During the anti-counterfeiting detection of banknotes, it will also use number recognition to determine whether the number on the banknote is a genuine currency number. For the authenticity of banknotes, it has become a common practice to add a number extraction and identification function to the equipment that realizes banknote anti-counterfeiting detection. [0003] In the prior art, to extract the number on the banknote, usually when the banknote passes through the transmission channel, the full-frame images of the front and back sides of the banknote are collected, and the banknote is usually s...
