This application relates to the fields of astronomical data processing and deep learning technology, and provides a method and apparatus for galaxy morphology recognition based on physical priors and deep visual features. The method obtains orientation-robust galaxy representations through multi-scale rotational equivariant feature extraction, and establishes visual and physical branches to jointly model morphological features and structural parameters. The physical branch incorporates astronomical structural parameters as auxiliary supervision to enhance physical interpretability. A gated fusion mechanism is used to achieve adaptive fusion of features from both branches, and end-to-end training is performed using classification loss and structural parameter regression loss to achieve automated galaxy morphology recognition. This method effectively improves the accuracy of fine-grained galaxy morphology classification and the physical interpretability of the model, outperforming existing state-of-the-art methods on some existing datasets, and has significant application value.
