Embodiments of the present disclosure disclose an image character recognition model generation method and apparatus, and a vertically-oriented character image recognition method and apparatus. The image character recognition model generation method includes: generating a rotated line character training sample, wherein the rotated line character training sample includes a rotated line character image and an expected character recognition result corresponding to the rotated line character image, and there is a difference of 90 degrees between character units in the rotated line character image and character units in a standard line character image; and training a set neural network by using the rotated line character training sample, to generate an image character recognition model. The technical solutions of the embodiments of the present disclosure overcome the technical defect that existing line character images cannot be directly used to train a vertically-oriented character image recognition model, thereby implementing the efficient recognition of vertically-oriented characters.
