This application belongs to the field of visual compensation technology and provides a visual compensation method under starlight conditions. Through pre-sampling and grayscale variance statistics, it achieves the determination of starlight compensation intervals and the dynamic division of target and background regions in the imaging plane. It adopts a sampling method with different exposure time series for the target and background regions to obtain multiple frames of original sampled data and pixel integration time. Based on the pixel integration time, it constructs a spatially variable gain matrix and completes inter-frame registration and gain normalization processing to separate signal and noise components in the image. The signal component is used as a sparse sampling stream, and the pixel variance distribution of the noise component is used as a hyperparameter of the variational inference algorithm. Image reconstruction is completed through probability density gradient estimation, making the variational inference process match the actual noise distribution characteristics under starlight conditions, thereby improving the quality and reliability of visual imaging under starlight conditions.

This invention relates to a DGT sampling device and method based on a glass sponge biomimetic eddy current anchoring structure, belonging to the field of environmental monitoring technology. The DGT sampling device includes a biomimetic outer shell, a filter protection layer, a diffusion layer, a bonding layer, and a base. The biomimetic outer shell includes a base grid layer and spiral guide ridges arranged along the axial direction of the outer shell on the outer surface of the base grid layer. The two ends of the biomimetic outer shell along its length are a closed end and an open end, respectively. The filter protection layer is disposed at the open end of the biomimetic outer shell. The diffusion layer is disposed on the side of the filter protection layer away from the biomimetic outer shell.
