1 results about "Radiation degradation" patented technology

This invention discloses a method for constructing and modeling degradation of multi-source data for cross-medium imaging under complex sea conditions, belonging to the field of underwater optical imaging. Addressing the difficulty of existing technologies in uniformly describing geometric distortion caused by sea surface fluctuations and radiation degradation resulting from water absorption and scattering, this invention integrates multi-source data from real-sea observations, controlled laboratory tests, and auxiliary references. It constructs a wave interface function and establishes a refractive distortion displacement field based on Snell's law, while simultaneously building a water radiation degradation model to form a unified degradation expression. Furthermore, it expands the sample space through physically guided data enhancement, generating a dataset with multi-dimensional degradation labels. This invention achieves joint modeling of geometric and radiation degradation in cross-medium imaging, providing a high-fidelity, high-generalization data foundation for image restoration model training.
