Abstract: The present disclosure discloses a method and an apparatus for processing image information. A specific implementation of the method comprises: recognizing each character in an original image and acquiring a position of the each character; matching a character in the original image with a character in a layout structured region of a template image, and recording identical characters or character strings in the original image and the template image as a matching point pair; acquiring a projective transformation matrix between the matching point pairs according to the position of the character in the original image and the position of the character in the layout structured region of the template image; registering the original image according to the projective transformation matrix to acquire a registered image; and recognizing the registered image to acquire a recognition result. This implementation simplifies steps of image matching in character recognition, enhances matching accuracy and universality, and reduces cost of development.
