Problems solved by technology
In the scanning of the answer sheet, it may be that the answer sheet is scanned and recognized due to the corners, positioning marks or other marking points being damaged during the scanning of the answer sheet.
When the current scanning system scans and recognizes the answer sheet, it cannot accurately point out which positioning mark point cannot be recognized, and relies on manual inspection of the answer sheet that failed to scan and identify which positioning mark point was not recognized
This way of relying on manual inspection will affect the efficiency of scanning work, which is not conducive to the rapid and smooth completion of scanning work

The invention discloses a detection method for scanning and collecting an abnormal answer sheet. A manufacturing template module, a database server, an answer sheet information automatic identification module and an identification result display module are included. The manufacturing template module is connected with the database server; the database server is connected with the answer sheet information automatic identification module; the answer sheet information automatic identification module is connected with the identification result display module; by comparing with a positioning mark point of a scanning template, the positioning mark points which cannot be identified on the answer sheet can be accurately found out; whether the scanned image is the correct answer sheet image or not can be pointed out, the damaged positioning mark points and the positions of the damaged positioning mark points on the answer sheet image can be accurately pointed out under the condition that the answer sheet positioning mark points are damaged, the efficiency and accuracy of scanning collection exception handling are effectively improved, and smooth completion of scanning work is promoted.
Description
technical field [0001] The invention relates to the technical field of scanning and collecting data, in particular to a detection method for scanning and collecting abnormal answer sheets. Background technique [0002] The first thing to do in the online marking system for paper-based examinations is to scan the paper-based answer sheets through a scanner to obtain the electronic version of the paper-based answer sheets. Before scanning the paper answer sheet, a scanning template must be made to locate the sign of the answer sheet, and then the information content of the answer sheet can be scanned and identified. In the scanning of the answer sheet, it may be that the corners of the answer sheet are bent, the positioning marks or other marking points are damaged during the scanning of the answer sheet, resulting in the failure of the answer sheet to be scanned and recognized. When the current scanning system scans and recognizes the answer sheet, it cannot accurately point...
