Embodiment Construction

[0058] The review method provided in the embodiments of this application is applicable but not limited to handwritten objective questions. Handwritten objective questions refer to questions that need to be handwritten by test takers and have fixed answers. For example, fill-in-the-blank questions in math, physics and chemistry test papers. In this question type, the test taker writes the answer by hand and does not need the answering process, just fill in the relevant answer. The marking requirements for this question type are: compare with the fixed answer to determine whether the candidate's answer is correct.

[0059] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other ...

Abstract

The invention provides a review method and device, and the method comprises the steps: obtaining an image and answer information of a to-be-reviewed object, carrying out the correlation processing ofthe answer information and answer information included in the image, obtaining a fusion feature, and determining a review result of the to-be-reviewed object according to the fusion feature. Therefore, character recognition of the answering area does not need to be carried out on the image of the to-be-reviewed object, and the fusion feature obtained through correlation processing of the answeringinformation and the answer information serves as the basis for determining the review result, so that the problem that the review result is inaccurate due to recognition errors can be avoided.

Description

Technical field [0001] This application relates to the field of electronic information, and in particular to a review method and device. Background technique [0002] In order to improve the efficiency of marking papers, handwriting objective questions (such as math fill-in-the-blank questions) have also begun to use smart marking methods. The existing intelligent marking method for handwritten objective questions is to segment the answer area of ​​the handwritten objective question area, that is, divide each fill-in into an answer area, and then perform the answering character for each of the segmented answer areas Recognition, and finally based on the recognition results and answers, the automatic judgment of the machine is performed to obtain the scoring result. [0003] It can be seen that the existing intelligent marking method obtains the marking result based on the character recognition result of the segmented answering area. Therefore, in the case of incorrect recognition,...
