Accurate temperature measurement method and system for infrared point cloud of transformer substation

The invention discloses an accurate temperature measurement method and system for infrared point cloud of a transformer substation. The method comprises the following steps: constructing a laser point cloud model of the transformer substation; acquiring radiance attributes of equipment parts made of different materials in the transformer station laser point cloud model; acquiring infrared pictures of the surface of the substation equipment at different measurement points and laser point cloud and environment data at the same moment; mapping the temperature information of the infrared picture to the transformer station laser point cloud model, and constructing a transformer station infrared point cloud model; the method comprises the following steps of: 1, performing data correction on the surface temperature of the equipment in the infrared point cloud model of the transformer substation by utilizing the radiance attribute of the equipment part, the laser point cloud, the environment data and the distance wei
