Oracle bone single character recognition method and device based on few-time learning

The invention provides an oracle single character recognition method and device based on few-time learning. The method comprises the following steps: acquiring an oracle single character picture; inputting the oracle-bone word picture into an oracle-bone word recognition model, and outputting an oracle-bone word category recognition result corresponding to the oracle-bone word picture; wherein the oracle single-character recognition model is obtained by training based on oracle single-character sample data and predetermined oracle single-character sample category labels. As the number of character samples of the oracle is small, the training mode of the oracle single character recognition model is carried out by adopting a few-time learning mode, the single character representation and feature extraction capability of the model can be enhanced at the same time according to the data long tail distribution characteristics of the oracle single characters, the over-fitting is overcome. And finally, the identifica
