Water conservancy and hydropower engineering multi-source data fusion method and terminal equipment

The invention discloses a water conservancy and hydropower engineering multi-source data fusion method and terminal equipment. The method comprises the steps that a research area BIM original file is converted into a first input file in a UDB format, a UDBX format, a 3DXML format, an RVT format or an SKP format; performing coordinate conversion on the CAD data of the research area in the first GIS platform, and converting the CAD data into a KML, KMZ or SHP format to serve as a second input file in a second GIS platform; taking the oblique photography file in the OSGB format of the research area as a third input file; taking the image data Tiff file of the research area as a fourth input file; taking the Tiff topographic file of the research area as a fifth input file; and inputting the first input file to the fifth input file into a second GIS platform for fusion to obtain a multi-source data fusion scene. According to the invention, multi-source data fusion can be realized, so that advanced technologies suc
