For lack of expressiveness and poor friendliness of the current two-dimensional visualization technology of infrared thermal imaging temperature measurement data of electric power equipment

which is not conducive to fault analysis and diagnosis

we conducted a study on the three-dimensional visualization scheme of infrared thermal imaging temperature measurement data of power equipment

and put forward a three-dimensional reality and two modes of model visualization of 3D point cloud model.Morever

the implementation strategies are given. The case verification results show that the visualization mode of the 3 D real-world model can visually display the local infrared temperature distribution characteristics of the device and is suitable for local rapid visualization scenarios; the visualization mode of the 3D point cloud model can accurately display the overall infrared temperature quantitative value of the device

which has advantages in the application in the overall device visualization scenario. The two modes can achieve complementary advantages. The research results can provide references for improving the expressiveness and viewing friendliness of the infrared thermal imaging temperature measurement data of the device

and they have some engineering values.
