The invention relates to a handwritten Chinese character writing quality evaluation method and system. The evaluation method comprises the following steps: obtaining a handwritten Chinese character image to be evaluated; Removing the field character lattice in the handwritten Chinese character image to be evaluated to obtain a font image; Performing grayscale processing on the font image to obtaina grayscale image; Performing perspective processing on the gray-scale image to obtain a transformed image; Segmenting the transformed image into a plurality of single Chinese characters; evaluatingThe writing quality of handwritten Chinese characters by convolution neural network. As that handwritten Chinese character image to be evaluated are sequentially processed for removing the field character lattice, Grayscale processing, perspective processing, segmentation processing, and evaluation of a single Chinese character through convolution neural network to determine the writing quality ofthe handwritten Chinese character image to be evaluated. The whole process reduces artificial participation, and the whole process is mechanized and fully automatic, so that the accuracy of the writing quality evaluation can be improved.
