The invention discloses a CNN-based handwritten Chinese text recognition method. According to the method, single handwritten Chinese recognition and a character segmentation algorithm are combined, automatic recognition of handwritten Chinese texts is achieved, and the method comprises the following steps that graying and binarization processing are conducted on text pictures, and then histogram projection is used for segmenting the Chinese texts; First, single-row characters are segmented through transverse scanning, and then single characters are segmented through longitudinal scanning. Carrying out scanning processing on a single Chinese picture, carrying out ortho-rectification on the Chinese picture, enabling the Chinese picture to be located in the middle of the picture, and leaving10 blank pixels in the upper, lower, left and right directions respectively; a convolutional neural network comprising four convolutional layers, four pooling layers and two full connection layers isconstructed based on a TensorFlow framework, and a training set is used for training; and inputting a to-be-tested picture, and performing recognition according to the constructed convolutional neuralnetwork.
