DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with embodiments. The following embodiments are for explanation of the present invention but the present invention is not limited to the following embodiments.

[0020] Embodiment 1: A method for counting votes based on barcode generation and detection, such as Figure 1 As shown, the following steps are included: S100, obtaining a barcode pattern of a barcode to be identified in a ticket sample, identifying the barcode pattern, obtaining identification feature information, and verifying the identification feature information to determine whether the barcode pattern meets a preset condition, wherein the barcode pattern includes a black bar pattern and a white bar pattern, and the identification feature information is the width corresponding to the black bar pattern and the white bar pattern; S200, if it is in compliance, the barcode pattern is parsed to obtain barcode information, wherein the barcode information includes voting number, voter information, voting time, voting category, digital signature, encoding rules and identification mark; S300, converting the barcode information into a barcode serial number string and segmenting it to obtain a check digit character and a non-check digit string, adding a check digit to the barcode serial number based on a preset check digit generation function, and obtaining a check barcode serial number; S400. Compare the barcode serial number string and the verification barcode serial number. If they are the same, query the corresponding ticket right information in the database based on the identification identifier of the barcode information and determine whether the ticket right exists. If it exists, verify the validity of the ticket right information. If valid, it is a valid ticket right and statistics are taken. The ticket right information and the barcode information correspond one to one.

[0021] The present invention is applied to a ticketing system, which is suitable for voting at a general meeting of owners. Figure 3 As shown, the entire execution process is as follows: 1. The staff logs into the ticketing system and generates a paper ticket sample document, which contains a barcode pattern that corresponds to the ticket information; 2. The staff prints the ticket sample into paper tickets and distributes them to the owners to exercise their voting rights; 3. The owner fills in his / her voting options on the paper ballot and puts the paper ballot into the ballot box; 4. After the voting period ends, the staff will unseal the ballot box and take out the paper ballots for display under the witness of multiple parties; 5. The staff uses a barcode scanner to scan the barcode on the paper ticket. The ticketing system identifies the barcode information and checks whether the barcode information is correctly identified. If the barcode information is detected to be incorrect, the page prompts the staff "Invalid barcode". The staff can re-scan the barcode for identification. If the barcode is correct, proceed to the next step; 6. The ticketing system queries the ticket information bound to the barcode, determines whether it is valid ticket information, and returns the result to the front-end page.

[0022] 7. After being detected as a "valid vote" by the ticketing system, the staff will enter the voting results of the paper ballot into the ticketing system on the current vote counting page.

[0023] In actual use, the ticketing system can quickly solve whether the vote is true and accurate during the counting process and can verify whether the voting rights are obtained. The present invention generates and detects barcodes for counting, which not only improves the efficiency of comparing voting rights information and reduces the error rate, but also binds the ticket code to the voting information one by one, ensuring the accuracy of the vote.

[0024] In one embodiment, the barcode pattern is generated by: Determine whether the target barcode pattern exists in the barcode database, and if not, save the target barcode pattern to the database; Convert the non-check digit string into a byte array, and process the byte array according to a preset rule to obtain a check digit value; Determine whether the check digit value is the same as the check digit character. If they are the same, splice the non-check digit character string and the check digit character into a barcode serial number character string in a preset splicing method, and bind the barcode serial number character string to the voting right information, wherein the preset splicing method is that the voting number, voter information, voting time, voting category, digital signature and identification mark are arranged in any order and the identification mark is located at the last position; Convert the barcode serial number string into barcode information, generate a corresponding barcode pattern based on the barcode information, and add the barcode pattern to the ticket sample document.

[0025] In this embodiment, when actually calculating the check digit value, the byte array elements can be added to obtain the total value, and then the total value is divided by 95 to obtain the remainder, and then added to 32 to obtain the check digit value. In another embodiment, the splicing method can also be: splicing in the form of "serial number non-check digit string#check digit character" to finally obtain the barcode serial number.

[0026] Since the barcode is a black and white pattern, the step of generating the barcode pattern according to the barcode information includes the following steps: Obtain target barcode information of the barcode pattern to be generated; Combine the target barcode information with the identification feature information to obtain the voting number, voter information, voting time, voting category and the width of the black bar pattern corresponding to the digital signature, and calculate the width of each white bar pattern based on the encoding rules; The identification mark is calculated by the identification feature information to obtain the width of the identification stripe pattern corresponding to the identification mark; The black stripe pattern, the white stripe pattern and the identification stripe pattern are arranged according to a preset arrangement rule to obtain a barcode pattern, wherein the identification stripe pattern is also a black stripe pattern.

[0027] In this embodiment, the heights of the white stripe pattern and the black stripe pattern are consistent, so there is no limitation on the heights of the white stripe pattern and the black stripe pattern. The preset arrangement rule can be consistent with the order of the voting number, voter information, voting time, voting category and digital signature, and can also be changed according to user requirements.

[0028] Due to concerns about barcode forgery, the barcode pattern can be verified and identified to obtain identification feature information, and the identification feature information can be verified, including the following steps: Preprocessing the barcode pattern to obtain a preprocessed pattern, wherein the preprocessing includes at least one or more of image noise reduction, background separation, and image correction; Converting the preprocessed pattern into a binary image, performing edge detection based on the binary image, determining the width and height of the black stripe pattern and the white stripe pattern, and obtaining a black stripe pattern area and a white stripe area; Determine whether the black bar pattern area and the white bar pattern area are bar code patterns in the bar code database according to the condition restriction calculation formula; If so, the total pixel sum of each black stripe pattern area is judged to obtain a judgment result, and based on the judgment result, it is judged whether each black stripe pattern area is abnormal. If it is abnormal, the barcode pattern does not meet the preset conditions.

[0029] During the entire process, each area of ​​the barcode pattern is first checked to determine whether it matches the barcode pattern in the database, and then a secondary judgment is made through pixels. This ensures that counterfeiting of the barcode pattern is excluded.

[0030] This embodiment is a specific construction process of the conditional restriction calculation formula. First, multiple restriction conditions are set for each black strip pattern area and each white strip area, and the conditional restriction calculation formula is constructed based on the multiple restriction conditions. Based on the conditional restriction calculation formula, each black strip pattern area and white strip area is judged. If it exceeds the preset matching threshold, the corresponding area is abnormal; The conditional restriction calculation formula is as follows:

[0031] in, express under conditions 1 if the condition is true, Indicates The preset matching threshold of the restriction conditions of the area, Indicates the number of constraints.

[0032] Before making a judgment, since the scanned image is not a very regular image, the following methods are also included before preprocessing the barcode pattern: The horizontal and vertical projection features of the barcode pattern are used to determine whether it is tilted. If it is tilted, correction is performed. After correction, the structure can be judged more accurately.

[0033] Embodiment 2: A voting system based on barcode generation and detection, such as Figure 2 As shown, it includes an acquisition and judgment module 100, a pattern analysis module 200, a segmentation and addition module 300 and a comparison and verification module 400; The acquisition and judgment module 100 is used to acquire the barcode pattern of the barcode to be identified in the ticket sample, identify the barcode pattern, obtain identification feature information, and verify the identification feature information to determine whether the barcode pattern meets the preset conditions, wherein the barcode pattern includes a black bar pattern and a white bar pattern, and the identification feature information is the width corresponding to the black bar pattern and the white bar pattern; The pattern analysis module 200 is configured to: if it meets the requirements, analyze the barcode pattern to obtain barcode information, wherein the barcode information includes voting number, voter information, voting time, voting category, digital signature, encoding rules and identification mark; The segmentation and adding module 300 is configured to: convert the barcode information into a barcode serial number string and segment it to obtain a check digit character and a non-check digit string, add a check digit to the barcode serial number based on a preset check digit generation function, and obtain a check barcode serial number; The comparison and verification module 400 is used to compare the barcode serial number string and the verification barcode serial number. If they are the same, the corresponding ticket right information in the database is queried based on the identification identifier of the barcode information and it is determined whether the ticket right exists. If it exists, the validity of the ticket right information is verified. If valid, it is a valid ticket right and statistics are performed, wherein the ticket right information and the barcode information correspond one to one.
