Dynamo-based side slope digital twinborn construction and dynamic updating method

The invention provides a Dynamo-based side slope digital twinborn construction and dynamic updating method, which comprises the following steps of: preprocessing multi-source data of a side slope, constructing a side slope engineering geological database, constructing a side slope earth surface model by utilizing an unmanned aerial vehicle oblique photography technology, and constructing a side slope digital twinborn model by adopting a spatial interpolation algorithm and visual programming software Dynamo based on geological drilling data. A slope digital twinborn body is constructed, coordinates of a slope excavation contour line are extracted, and a slope excavation three-dimensional model and a support model are rapidly established and dynamically modified by using Dynamo. According to the method, the side slope digital twin model can be quickly constructed, the excavation and support model can be dynamically and efficiently updated according to the actual excavation parameters of the side slope, a simula
