Embodiment 1

[0027] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0028] A device for identifying instant ticketing through a scratch area, comprising at least one sensor 1 arranged in a line perpendicular to the direction of instant ticketing, the sensor 1 is an infrared sensor, and the wavelength of the infrared light emitted by the infrared sensor is 940nm, the sensor 1 is set on the ticketing path of instant ticketing.

[0029] The infrared sensor with a wavelength of 940nm distinguishes the scratch area and the non-scratch area by the difference in light transmittance or reflectance.

Embodiment 2

[0030] Please refer to figure 1 , the second embodiment of the present invention is:

[0031] A device that recognizes tickets by scratching the area, on the basis of the first embodiment, further includes at least one ticket delivery roller 2, a ticket issuance roller 3, and a ticket breaking knife 4, and the ticket breaking knife 4 is located at the delivery box. Between the ticket roller 2 and the ticket roller 3, the sensor 1 is an infrared through-ray sensor, and the sensor 1 is located between the ticket roller 3 and the first ticket delivery roller 2 along the ticket issuing direction, Preferably, the sensor 1 is located between the ticket feeding roller 2 and the ticket breaking knife 4 .

[0032] When the sensor 1 arrives at the ticket cutting knife 4 when the tail edge of the instant ticket that is about to issue the ticket arrives, it realizes the complete detection of the instant ticket.

[0033] Please refer to figure 2 , a method for instant ticketing through...

Embodiment 3

[0054] Please refer to figure 2 , Embodiment three of the present invention is:

[0055] A method for instant ticketing through scratch area identification, the method is:

[0056] At least one sensor arranged in a line perpendicular to the instant ticket issuing direction detects the boundary point coordinates of the instant ticket scratch area, and stores it as at least one initial array;

[0057] At least one sensor detects the coordinates of the boundary point of the scratch area of ​​the transported ticket and records it as at least one detection array;

[0058] Compare whether the initial array passing through each sensor matches the detection array, and if they match, it is determined that the delivered invoice is correct.

Abstract

The invention provides a device and method for recognizing billings through prize scraping areas. The device comprises at least one sensor which is arranged in a line along a direction vertical to the billing drawing direction of billings, wherein the sensors are infrared sensors and the wavelength of the infrared lights transmitted by the infrared sensors is 940mm. The method comprises the following steps: detecting boundary point coordinates of prize scraping areas of billings by at least one sensor which is arranged in a line along a direction vertical to the billing drawing direction of the billings, and storing the boundary point coordinates as at least one initial array; detecting the boundary point coordinate of the prize scraping area of a transmitted billing by the at least one sensor, and recording the boundary point coordinate as at least one detection array; and comparing whether initial arrays passing through each sensor are matched with the detection arrays, and if the initial arrays are matched with the detection arrays, determining that the transmitted billing is correct. According to the method, the sensors are used for recognizing the correctness of the boundary point coordinates of the price scraping areas, so as to judge whether the transmitted billings are correct, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of lottery identification, in particular to a device and method for identifying and issuing tickets by scratching area identification. Background technique [0002] The identification of lottery tickets in the existing automatic lottery ticket issuing machines is mainly realized by means of image processing. For example, the Chinese invention patent with the publication number CN103489254A discloses a lottery identification method and system. The method is as follows: using a CMOS black and white image sensor to obtain a lottery image; preprocessing the lottery image; Recognition and acquisition of lottery betting information; the preprocessing includes: image binarization processing, image barrel distortion correction; the lottery identification includes: identification of positioning area and identification of characters in the filling area. By obtaining the image of the lottery ticket, binarizing the ima...
