The embodiment of the invention relates to a dot matrix imaging handwriting system. The dot matrix imaging handwriting system comprises a handwriting medium; and a handwriting device comprising a housing with an accommodating part therein, an image collector arranged at the front end of the accommodating part, and performing image acquisition on the dot matrix address code corresponding to the moving position of the handwriting device on the handwriting surface, a processor arranged in the accommodating part and connected with the image collector, determining a first displacement of the targetimage on the object surface of the image collector and a second displacement of the target image on the image surface of the image collector according to a target image acquired by the image collector; and a self-compensating device arranged in the accommodating part and determining a self-compensating parameter according to the first displacement, the second displacement and the lateral magnification. The processor calculates a position deviation of the target image according to the self-compensating parameter, and restores image data of the target image according to the position deviation.
