Three-dimensional Visualization Scheme of Infrared Thermal Temperature Measurement Data for Substaition Electric Power Equipment

For lack of expressiveness and poor friendliness of the current two-dimensional visualiza-tion 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 tempera-ture 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 implementa-tion strategies are given. The case verification results show that the visualization mode of the 3D real-world model can visually display the local infrared temperature distribution characteristics of the device and is suitable for local rapid visualization scenarios; the visu-alization 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 advan-tages. 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. © 2021, High Voltage Engineering Editorial Department of CEPRI.
