Problems solved by technology
For the filling of objective questions on the answer sheet, it is difficult for scanning equipment to distinguish whether it is rubbing or not, and the ability to identify irregular filling is poor
In addition, after the scanning equipment is used for filling and identification, it is impossible to realize the statistics of the respondents' scores, and the degree of automation is not high.

The invention discloses a general answer recognition method and system, a storage medium and computing equipment, and the method comprises the steps: carrying out the macroscopic positioning according to three black blocks in an answer sheet picture, and cutting and zooming the answer sheet picture into a uniform size; according to the black strip-shaped square block at the rightmost end of each row of options and the black square block at the uppermost end, the coordinates of the options filled in the answer sheet picture are identified, and the answer result of the objective question is determined according to the identified pixel size of each option; until all questions in the answer sheet picture are identified; drawing the identified filling results into a matrix; and analyzing a data result, and counting an answer score. According to the invention, no special scanning equipment is used for scanning the answer sheet, the expenditure and cost for purchasing and maintaining the scanning equipment are greatly reduced, no special requirements for paper for printing the answer sheet and a user are provided, and the answer condition of the answer sheet can be more simply and quickly counted for the user.
Description
technical field [0001] The invention belongs to the technical field of electronic information, and in particular relates to a general answer recognition method, system, storage medium and computing equipment. Background technique [0002] With the development of electronic information, computer automatic identification of answer sheets to complete automatic marking has gradually replaced manual marking, because manual marking has errors, heavy workload and low efficiency, which consumes the energy of marking teachers. Using computers to automatically identify answer sheets to assist teachers in marking can greatly improve work efficiency and reduce the probability of failure in marking objective questions. [0003] However, most of the answer sheets commonly used in the existing examinations need to be scanned with a specific scanning device. The special scanning device is expensive and requires professional technicians to perform maintenance operations, and the scanning dev...
