Abstract

The invention provides a questionnaire survey identification method and system, and relates to the technical field of image identification. The invention relates to a questionnaire survey identification method, which is characterized by comprising the following steps of: scanning and identifying a questionnaire with a plurality of choice questions; correcting and cutting the questionnaire to obtain a plurality of option areas of each choice question; identifying the artificial check traces of the option area, specifically comprising the following steps: converting the questionnaire into a grayscale image, and carrying out edge detection on the plurality of artificial check traces of the questionnaire; processing the edge traces, filtering invalid information in the edge traces, and amplifying useful information; different manual checking traces are surrounded by rectangular frames, the size of each rectangular frame is detected, and if the size is abnormal, the option is checked. The correct rate of questionnaire survey recognition can be improved, and the statistical analysis efficiency of questionnaire survey is improved.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to a method and system for questionnaire survey recognition. Background technique [0002] At present, most of the questionnaires are collected and analyzed manually. The currently known automatic recognition 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. But this solution has a disadvantage: the user must handwrite the answer in a specific area, especially the ticked answer is easily unrecognizable. Therefore, there is currently a need for a questionnaire identification method and system that can automatically identify questionnaire results and improve accuracy and identification efficiency. Contents of the invention [0003] One of the objectives of the present invention is to provide a method for identifying questionnaires, w...
