GIS equipment monitoring method

The invention provides a GIS (Geographic Information System) equipment monitoring method, which comprises the following steps of: selecting static feature points according to a monitoring picture of monitoring equipment; the monitoring picture comprises a dynamic part and a static part; the static part comprises GIS equipment and a surrounding static environment; the dynamic part comprises at least one of a person, a vehicle and an appliance; based on the point cloud data of the GIS equipment and the surrounding static environment, constructing an overall three-dimensional model of the GIS equipment and the surrounding static environment; according to the two-dimensional coordinates and the three-dimensional coordinates of the static feature points, a corresponding relation between a two-dimensional coordinate system of the monitoring picture and a three-dimensional coordinate system of the overall three-dimensional model is established, and the three-dimensional coordinates of the static part are obtained; b
