Spatio-temporal information semantic conversion matching method based on highway stake numbers

The invention discloses a spatial-temporal information semantic conversion matching method based on highway stake marks, which comprises the following steps: S1, importing highway electromechanical equipment data including descriptive position, highway direction, hectometer stake marks and equipment type specification data; s2, importing basic map data to a twin platform, automatically generating basic three-dimensional scenes such as terrains and roads, and having unified geographic information attributes: fusing a base plate with GIS attributes, importing projection coordinate position information of electromechanical equipment, and automatically generating basic three-dimensional models of the terrains and the roads in combination with a basic map layer of a terrain map; through the technology of automatically matching stake numbers based on highway electromechanical equipment, the rapid construction of a traffic digital twin model is realized, and the construction efficiency of a digital twin platform is
