Abstract

The invention relates to the field of data processing, and provides an objective question marking method and device based on an answer sheet, equipment and a storage medium. The method comprises the following steps: shooting an answer sheet after answering to obtain a digital image of the answer sheet; collecting a discrete curve corresponding to a horizontal line segment and a discrete curve corresponding to a vertical line segment based on the digital image; positioning grid units from the digital image according to the horizontal discrete curve and the vertical discrete curve; obtaining the handwritten answer content of each question from each positioned grid unit; recognizing the handwritten answer content to obtain an recognition result of each question; and comparing the recognition result of each question with a preset standard answer one by one to obtain a reviewing result of each question. According to the method, grid cell positioning is carried out through discrete curves, when the answer sheet is warped and other deformations, the method is more accurate compared with a traditional straight line detection algorithm, and compared with an algorithm based on deep learning, the calculation power demand is smaller, and the method is more suitable for real-time application scenarios based on edge calculation, such as real-time classroom test and the like.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method, device, equipment and storage medium for reviewing objective questions based on answer sheets. Background technique [0002] With the development of artificial intelligence technology, smart education has gradually entered the classroom. Real-time marking and statistics of students' classroom tests in the classroom is a major challenge in the field of smart education applications, and the demand is also very strong. If the real-time marking and statistics of students' classroom tests can be completed in real time in the classroom, teachers will be able to grasp the learning situation in a timely manner, optimize the organization of classroom teaching activities, improve the efficiency of teaching and learning, and reduce the burden on students and teachers after class. [0003] The prior art mainly adopts two schemes to realize the review of classroom tests. The first s...
