Abstract: Disclosed is a natural scene text recognition method based on sequence transformation 
correction and an attention mechanism, comprising the steps of data acquisition, data 
processing, label generation, network training and network testing; wherein the network 
training comprises the steps of constructing a recognition network, and inputting the training 
data and the processed labels into a pre-designed recognition network to complete the training 
of the recognition network; the recognition network comprises a sequence transformation 
corrector and an attention mechanism-based text recognizer; the sequence transformation 
corrector comprises multiple convolutional layers, a nonlinear layer and a pooling layer, and 
further comprises a decomposition layer and a positioning network composed of multiple fully 
connected layers, and the attention mechanism-based text recognizer the comprises a feature 
coding network and an attention mechanism-based decoder. The present invention greatly 
reduces the recognition difficulty of the recognition model with high recognition accuracy rate 
and strong robustness, and provides a good recognition performance for texts with irregular 
shapes.
