The invention discloses a writing scoring and error correction method and an interactive system, which are used for scoring and error correction of written characters in a copybook. The system transmits a copybook image by collecting the copybook image, and carrys out image processing on the acquired image, and calculates a minimum rectangular frame and a centroid of each character after segmentation; compares with relevant characteristics of standard characters, performs operations such as scaling and translation on written characters, compares the adjusted characters with the standard characters, calculates a character similarity ratio, and finally calculates the score of each character by combining the similarity ratio, the size ratio and the deviation ratio. Meanwhile, a single character is segmented, a small area is scored, a specific wrong stroke is pointed out, and a correct writing method is given. According to the method, the problems of guidance and interaction deficiency inwriting practice and scoring systems are solved, and the method has the advantages in the aspects of clarity, guidance, interactivity and the like of scoring rules.
