A document proofreading method includes the steps of obtaining the text framed by a plurality of first text frames in an original document file and the text framed by a plurality of second text frames in an image file of the document to be inspected by a computer device; pairing M (2 ≤ M ≤ N) framed texts that are unique in the first text frame with M framed texts that are unique in the second text frame; obtaining the coordinates of four corners and midpoints of M first text frames and M second text frames; calculating a coordinate transformation matrix according to the correspondence between the coordinates of the M first text frames and the coordinates of the M second text frames; projecting the first text frames into the image file of the document to be inspected by using the coordinate transformation matrix; and comparing the text framed by the first text frame of the original document file with the text framed by the first text frame of the image file of the document to be inspected.
