For the problem that it is difficult for computer to recognize rotated multi-font character

a method of character recognition based on the Eigen space approach is proposed. The character features are extracted

the character feature space is established

and then the trajectories of character is determined.The characters and the corresponding rotation angle is identified by comparing similarity of characteristics of the character under test and the trajectory though space distances. Finally

experiments have been performed taking a single font characters and multi-font characters as examples. It is found that 54 characters among 62 characters can get 100% recognition rate and the accuracy of rotation angle can get 94%. Experiments indicate that the proposed method has a high recognition rate.
