Abstract
An automatic scoring method, performed by a processing device, includes: obtaining a current test paper image, wherein a hand-writing script on the current test paper image has a script color; determining whether the script color is a designated color; determining whether a database stores a reference text string if the script color is not the designated color; aligning the current test paper image with a reference test paper image corresponding to the reference text string and using reference coordinates to compare the current test paper image with the current test paper image to output a test score when the database stores the reference text string; and identifying the hand-writing script to store an identification result as the reference text string and storing position coordinates of the hand-writing script on the current test paper image as the reference coordinates if the script color is the designated color.
