Refined 3D Quaternary geological modeling can reveal the spatial and geological structures of strata from a 3D perspective, which is an essential subject in current Quaternary geology and 3D GIS research. This research addresses the critical challenge posed by the significant discontinuity and heterogeneity of Quaternary strata, which result from multiple depositional events and lead to complex stratigraphic structures that ar...

Seafloor unconstrained environment video is shot in uncontrolled open sea area. There are multiple backgrounds, complex illumination and weather changes, and rapid growth of algae and attached lenses, which affect the stability of video shooting quality, resulting in difficulty in image recognition. At present, there is still no algorithm that is superior to other methods generally, and it is necessary to build a model combine...
