Description

Technical Field

[0001] This invention relates to the field of electronic identification check-in, and more particularly to an electronically identifiable and storable method for check-in in examination rooms. Background Technology

[0002] In various large-scale, multi-session examination activities (such as national education examinations and qualification certification examinations), paper-based examination attendance sheets are crucial legal documents and examination records that document candidates' entry and exit, and are signed by the candidates themselves. They are used not only to verify whether candidates actually attended, but the handwritten signature on the sheet can also serve as important evidence, when necessary, to determine whether "proxy testing" has occurred.

[0003] However, the current process for handling sign-in sheets in examination administration is usually as follows: after the examination, each examination room collects the sign-in sheets, which are then manually counted and sorted along with other examination administration materials. Finally, they are packed and sealed in the form of physical archives. This traditional management method has many drawbacks, such as difficulty in storage and retrieval, high risk of long-term preservation, and difficulties in subsequent data retrieval. Therefore, how to achieve the intelligent and structured transformation of the sign-in sheet from physical to electronic form through a low-cost and high-efficiency technical means without changing the existing core legal process of paper sign-in and signature, and to maintain a strong correlation between the electronic file and the original examination room information, has become an urgent technical problem to be solved. Summary of the Invention

[0004] Therefore, the present invention provides an electronically identifiable and storable examination room sign-in method to overcome the problems of low efficiency, high risk of long-term storage, and difficulty in subsequent retrieval of paper examination room sign-in sheets in the prior art.

[0005] To achieve the above objectives, the present invention provides an electronically identifiable and storable examination room sign-in method, comprising: An identification code is generated based on the examination room information, a barcode is generated based on the identification code, and at least three positioning markers for image orientation recognition are generated simultaneously. The barcode and the positioning mark are set in the preset non-signing area of ​​the sign-in sheet; The sign-in sheet is scanned using a scanning device to obtain the original scanned image, and the placement of the sign-in sheet is determined based on the positioning mark. The original scanned image is subjected to a rotational geometric transformation to generate a standard orthogonal image with a unified orientation standard; The barcode is identified in the standard forward image to obtain the examination room information; Based on the examination room information matching storage path, the standard positive image is named according to the naming rules that include the examination room identification information, and then saved to the electronic storage path.

[0006] Furthermore, the identification code is a string composed of the examination area code, examination site code, and examination room number concatenated according to a predetermined rule.

[0007] Furthermore, the positioning markers include at least three identical graphic markers, which are respectively positioned near the diagonal corners of the front of the sign-in sheet, for example, at the upper left, lower left, and upper right.

[0008] Further, determining the placement orientation of the sign-in sheet based on the positioning marker includes: Based on the relative positional relationship of the positioning marks, determine whether the original scanned image has an abnormal aspect ratio, whether the original scanned image is frontal, whether the original scanned image is skewed, and whether the original scanned image has any missing parts.

[0009] Furthermore, the rules for generating the electronic storage path include, The test area code is used as the root directory. Subdirectories are created under the test site code, and the final storage directory is created under the test room number.

[0010] Furthermore, the naming rules for the standard forward image include the identification code and the scan timestamp.

[0011] Furthermore, it also includes establishing an electronic sign-in sheet index database containing examination room identification information, storage path, image file name, and scanning time for categorized storage.

[0012] Furthermore, authentication is set for the index database, allowing only authenticated clients to access the data stored in the index database.

[0013] Furthermore, it provides a query interface based on test area, test site, test room, or time range, and locates and retrieves the corresponding standard positive image according to the query conditions.

[0014] Furthermore, the identification code corresponds one-to-one with the examination room information, and the identification code corresponds one-to-one with the barcode.

[0015] Compared with existing technologies, this invention solves the problems of low efficiency in manual sorting, image orientation disorder, and difficulty in archiving and management during the electronic signing-in sheet process. It realizes fast, accurate, and structured electronic archiving and convenient retrieval of signing-in sheets, improves the informatization level of examination affairs file management, and has low implementation cost and strong compatibility.

[0016] In particular, thanks to the positioning and marking technology, there is no need for manual pre-alignment of paper during scanning. It supports disordered paper loading and batch scanning, and the system automatically outputs images with uniform orientation, which greatly reduces manual intervention and improves the overall speed of electronic processing.

[0017] In particular, by recognizing the examination room information in the barcode, the system can automatically create a folder directory structure that conforms to the examination administration logic and assign names with clear meanings to the image files, realizing a strong association between electronic archives and original examination room information, enabling the categorized storage of massive electronic sign-in sheets.

[0018] In particular, based on the automatically generated structured storage system or the established index database, users can quickly and accurately locate the target sign-in sheet image by using information such as examination area, examination site, and examination room number, just like searching for ordinary files on a computer, which facilitates rapid data retrieval later.

[0019] In particular, this invention does not change the essential function and usage process of the sign-in sheet. The electronic processing can make full use of the high-speed document scanners (such as OMR devices for scanning answer sheets) and their supporting computer systems commonly equipped by existing examination institutions. It can be achieved through software upgrades without the need to purchase additional dedicated hardware, resulting in extremely low implementation costs and easy promotion.

[0020] In particular, electronic storage effectively avoids the risk of physical damage to paper archives, and can further enhance data security through off-site backup and other means, which is conducive to the permanent preservation of examination archives. Attached Figure Description

[0026] Please see Figure 1 as well as Figure 2 As shown, Figure 1 This is a schematic diagram illustrating the steps of an electronically identifiable and storable examination room check-in method according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the attendance sheet layout according to an embodiment of the invention. The electronically identifiable and storable examination room attendance method of the present invention includes: Step S1: Generate an identification code based on the examination room information, generate a barcode based on the identification code, and simultaneously generate at least three positioning markers for image orientation recognition; Step S2: Set the barcode and the positioning mark in the preset non-signing area of ​​the sign-in sheet; Step S3: Use a scanning device to scan the signed sign-in sheet, obtain the original scanned image, and determine the placement orientation of the sign-in sheet based on the positioning mark; Step S4: Perform a rotational geometric transformation on the original scanned image to generate a standard forward image with a unified orientation standard; Step S5: Identify the barcode in the standard forward image to obtain the examination room information; Step S6: Based on the examination room information matching storage path, the standard positive image is named according to the naming rules that include the examination room identification information, and saved to the electronic storage path.

[0027] Specifically, the identification code is a string composed of the examination area code, examination site code, and examination room number concatenated according to a predetermined rule.

[0028] In practice, taking the examination admission ticket number formatting rule used in a certain province as an example, which is a 13-digit pure numeric code, The first two digits are the exam year code, taking the last two digits of the year, such as 26 for 2026. The third and fourth digits are the exam item code, such as 01 for the provincial civil service exam and 02 for the public institution exam. The fifth and sixth digits are the exam area code, which has a fixed correspondence, such as 01 for city A, 02 for city B, and 03 for city C. The seventh and eighth digits are the exam center code, such as 01 for No. 1 Middle School in city A. The ninth and eleventh digits are the exam room number, such as 001 for the first exam room. The twelfth and thirteenth digits are the seat number, such as 01 for exam room number 1 in this exam room.

[0029] The identification code on the sign-in sheet is usually generated from the 1st to 11th digits of the admission ticket to create a one-dimensional barcode. Through rule parsing, it can be quickly categorized, organized, and stored in a tree structure according to the exam year, exam item, exam area, exam center, and exam room.

[0030] Specifically, the positioning markers include at least three identical graphic markers, each positioned diagonally on the front of the sign-in sheet.

[0031] Specifically, determining the placement of the sign-in sheet based on the positioning marker includes: Based on the relative positional relationship of the positioning marks, determine whether the original scanned image has an abnormal aspect ratio, whether the original scanned image is frontal, whether the original scanned image is skewed, and whether the original scanned image has any missing parts.

[0032] In practice, black squares can be placed in the upper left, lower left, and upper right corners of the sign-in sheet. The size of the black squares can be adjusted by those skilled in the art based on the actual area of ​​the sign-in sheet, which will not be elaborated here.

[0033] During implementation, when generating a standard forward image with a unified orientation standard, Batch scanning and automatic image correction. After the exam, all attendance sheets from the exam rooms are collected. The operator places multiple attendance sheets (possibly in different orientations) into the feeder of the high-speed duplex scanner. The scanner sequentially scans each sheet double-sided, generating an original scanned image for each page.

[0034] Obtain the first and second images of both sides of a single sheet of paper.

[0035] Image preprocessing (such as grayscale conversion, binarization, and noise reduction) is performed on the first and second images respectively.

[0036] In the preprocessed image, search for regions that match the preset positioning marker template (black squares, etc.).

[0037] For example, the distance between the black squares that are combinations of the upper left and lower left, and the upper left and upper right, can determine whether the scale of the original scanned image is correct and whether it has been scaled. The three black squares can be used to determine whether the original scanned image is the front of the sign-in sheet and whether the original scanned image is skewed, so that it can be corrected. The three black squares can be used to determine whether the original scanned image is bent or incomplete.

[0038] Specifically, the rules for generating the electronic storage path include, The test area code is used as the root directory. Subdirectories are created under the test site code, and the final storage directory is created under the test room number.

[0039] During implementation, under the root directory "Electronic Sign-in Sheet Archive", a subdirectory "Examination Year" is created, which in turn creates a subdirectory "Examination Items", and then a subdirectory "Examination Area" is created. Under this subdirectory, "Examination Center" is created, and under that, "Examination Room" is created. Then, the standard forward image file of this sign-in sheet is named according to the corresponding format and moved and stored in the "... / Examination Room / " folder.

[0040] Specifically, the naming rules for the standard forward image include the identification code and the scan timestamp.

[0041] Specifically, this also includes establishing an electronic sign-in table index database containing exam room identification information, storage path, image file name, and scanning time for categorized storage.

[0042] Specifically, authentication is set for the index database, allowing only authenticated clients to access the data stored in the index database.

[0043] Specifically, it provides a query interface based on test area, test site, test room, or time range, and locates and retrieves the corresponding standard positive image according to the query conditions.

[0044] Specifically, the identification code corresponds one-to-one with the examination room information, and the identification code corresponds one-to-one with the barcode.

[0045] If the electronically identifiable and storable examination room check-in method of the present invention is implemented as a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, or all or part of the technical solution, can be embodied in the form of a software product.
