The invention belongs to the technical field of answer sheet identification and particularly relates to an accurate answer sheet identification point positioning method and system. According to the method or the system, coordinates of standard identification points of a sample answer sheet image are positioned, and a standard position topological graph is generated based on the coordinates of standard identification points; the standard identification points in the standard position topological graph are traversed, and identification points, matched with the traversed standard identification points in the answer sheet image to be identified in position are looked up based on the traversed coordinates of the standard identification points; if the identification points matched with the positions are looked up, the identification points can be accurately positioned, and thus accurate positioning of answered question positions is completed.
