摘要
The present invention relates to an automatic grading system using a test sheet with integrated answers and a teaching material with integrated answers and a method thereof. Also, the automatic grading system using a test sheet with integrated answers and a teaching material with integrated answers comprises: a receiving unit to receive a photographed image obtained by photographing a test sheet with integrated answers or a teaching material with integrated answers from a test taker terminal; an identification unit to identify information including a test subject from the photographed image; a preprocessing unit to convert the photographed image into a preset standard; an answer position tracking unit to analyze the converted photographed image to track test questions and an answer position for each test question; and a grading unit to recognize an answer marked or written on the answer position for each test question, and determine whether the answer is correct or wrong to generate grading results of the test sheet with integrated answers or the teaching material with integrated answers. Time and efforts for grading answers of a test taker by a test giver can be reduced, and a separate OMR sheet for grading the answers of the test taker is not required, thereby reducing expenses.;COPYRIGHT KIPO 2019
