Abstract

The invention provides a questionnaire survey identification method and system, which relate to the technical field of image identification. A method for identifying a questionnaire survey, characterized in that it comprises the following steps: scanning and identifying a questionnaire with multiple multiple-choice questions; correcting and cutting the aforementioned questionnaire to obtain multiple option areas for each of the multiple-choice questions; identifying the aforementioned multiple-choice questions The manual check marks in the options area specifically include the following steps: converting the above questionnaire into a grayscale image, and performing edge detection on multiple manual check marks in the above questionnaire; processing the edge marks, filtering invalid information, And zoom in on useful information; different above-mentioned manual check marks are surrounded by rectangular boxes, and the size of each of the above-mentioned rectangular boxes is detected. If the size is abnormal, this option is considered to be checked. The invention can improve the correct rate of identifying the questionnaire and speed up the statistical analysis efficiency of the questionnaire.

Description

technical field [0001] The present invention relates to the technical field of image recognition, and in particular, to a method and system for identifying a questionnaire. Background technique [0002] At present, most of the questionnaires are collected and analyzed manually. The known automatic identification of questionnaire images using computer technology is based on OCR technology to extract the characters of the questionnaire answers, so as to obtain the results of the questionnaire. However, this scheme has a disadvantage: the user must handwrite the answer in a specific area, especially the checked answer is easy to be unrecognizable. Therefore, there is currently a need for a questionnaire identification method and system that can automatically identify the results of the questionnaire and improve the accuracy and identification efficiency. SUMMARY OF THE INVENTION [0003] One of the objectives of the present invention is to provide a method for identifying a ...
