Embodiment Construction
[0026] The invention uses high-definition images of substations and DEM data to construct real three-dimensional scenes. Users can query the coordinates, elevation and other information of any point in the scene, and the system can plan inspection routes. The implementation steps are as follows:
[0027] Step 1 Generate road network:
[0028] Four types of data are needed in the three-dimensional GIS system of substation: substation digital satellite map, substation elevation information (longitude, latitude, altitude), substation route network information, and equipment information. The route network information of the substation in the present invention is obtained by collecting the latitude and longitude data of all routes in the substation through Garmin (equipment for recording latitude and longitude). The data types of the inspection algorithm are all point coordinates (latitude and longitude) data, and the present invention adopts Garmin (equipment for recording latit...
