The invention relates to a score automatic logging method based on image analysis. The score automatic logging method based on image analysis comprises steps of using a scanner to scan a blank test paper sample, performing OCR identification on the blank test paper sample, performing character disassembling on an OCR identification result in order to factor out a title area coordinate, a question type and a sore value of each question in the blank test paper, using an automatic scanner to perform batch scanning on question sheets of all students to obtain a question sheet image, extracting a couture body of effective paper marking handwriting of a teacher from the question sheet image, inputting the effective handwriting couture into a Tensorflow to perform identification, performing statistics to obtain a practical score of each question according to an identification result, the coordinate of the question area corresponding to the identification result and a question mark value corresponding to the question area coordinate, and the inputting the practical score of each question into a database according to a sequence number of each question. The score automatic inputting method based on image analysis can realize automatic collection, identification, statistic and inputting of the scores of the student question sheets.
