OMR Card Scoring Method Using Template Matching

초록

In this paper, we propose an algorithm that recognizes and scores the answer by photographing the marked OMR card with a mobile phone for individual use. First, the area of the answer is extracted from the OMR card. After presenting the OMR scoring method of the two methods, the two methods are compared and analyzed. The first algorithm is a method of finding marked and unmarked questions using the marked area as a template, and sorting them to extract the correct answer. The second algorithm is a method of extracting the correct answer by comparing the coordinate values of the marked answer and the answer number for each question using all item numbers and the marked area as a template.
