Embodiment 1

[0023] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0024] A device for identifying instant tickets through a scratch area, comprising at least two sensors 1 symmetrically arranged in a line perpendicular to the direction of instant ticket issuance, at least one ticket delivery roller 2, ticket issuance roller 3, and ticket breaking knife 4 , the sensor 1 is an infrared sensor, the infrared light emitted by the infrared sensor has a wavelength of 940nm, the ticket cutting knife 4 is located between the ticket delivery roller 2 and the ticket issuance roller 3, and the sensor 1 is located at the delivery Between the ticket roller 2 and the ticket breaking knife 4.

[0025] 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; the sensor 1 is symmetrically set, and only the data detected by sensor 1, that is, the two areas of the ticket It is only...

Embodiment 2

[0026] Please refer to figure 1 , the second embodiment of the present invention is:

[0027] A device for issuing tickets through scratch area identification. On the basis of Embodiment 1, the sensor 1 is an infrared through-beam sensor, and the number of the sensors 1 is 4-6.

[0028] Please refer to figure 2 , a method for instant ticketing through scratch area identification, the method is:

[0029] At least two sensors arranged symmetrically in a line perpendicular to the direction of instant ticket issuing, respectively detect the coordinates of the boundary points of the instant ticket scratching area in the two states of the leading edge and the trailing edge of the instant ticket, and store them as an initial array of at least one;

[0030] At least two sensors detect the coordinates of the boundary points of the scratch area that is transported to be issued tickets, and record them as at least two detection arrays;

[0031] Compare whether the initial array pass...

Embodiment 3

[0052] Please refer to figure 2 , Embodiment three of the present invention is:

[0053] A method for instant ticketing through scratch area identification, the method is:

[0054] At least two sensors arranged symmetrically in a line perpendicular to the direction of instant ticket issuing, respectively detect the coordinates of the boundary points of the instant ticket scratching area in the two states of the leading edge and the trailing edge of the instant ticket, and store them as an initial array of at least one;

[0055] At least two sensors detect the coordinates of the boundary points of the scratch area that is transported to be issued tickets, and record them as at least two detection arrays;

[0056] Compare whether the initial array passing through each sensor in the above two states matches the detection array, and if the initial array in at least one state matches the detection array, it is determined that the invoice that is delivered is correct.

Abstract

The invention provides a device and method for identifying an instant lottery through a scratch area. The device comprises two or more sensors which are symmetrically arranged in a straight line in the direction perpendicular to the lottery output direction of the instant lottery, the sensors are infrared sensors, and the wavelength of infrared light emitted by each infrared sensor is 940nm. The method comprises the steps that through the two or more sensors which are symmetrically arranged in a straight line in the direction perpendicular to the lottery output direction of the instant lottery, separately detecting boundary point coordinates of the scratch area of the instant lottery when the instant lottery is in the state that the head edge is located at the front and when the instant lottery is in the state that the tail edge is located at the front, and storing the boundary point coordinates into one or more initial arrays; through the two or more sensors, detecting the boundary point coordinates of the scratch area of the conveyed instant lottery, and recording the boundary point coordinates into two or more detection arrays; comparing and checking whether the initial array and the detection array passing through each sensor in each state are matched with each other or not, and if the initial arrays and the detection arrays in either or both states are matched, determining that the conveyed instant lottery is correct. By means of the method, operation can be conducted conveniently and quickly.

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...
