Abstract

Aiming at the limitations that the traditional substation three-dimensional temperature re?construction technology not only relies on high-precision laser radar point cloud completion and three?-?dimensional scanning technology

but also frequently encounters issues such as insufficient point cloud density and distortion of appearance representation

given the inherent characteristics of infrared images of low textures and high noise

a dual-path three-dimensional modeling system based on infrared images is proposed. This system completes high-density temperature distribution reconstruction through the cross?-domain fusion of thermal structural features and geometric priors

combined with a three?-dimensional Gaussian splatting algorithm

ultimately generating three-dimensional models of substation scenes and equipment that achieve high-density temperature distribution reconstruction while maintaining extremely high morphological fidelity. Compared with existing methods

the model accuracy is improved by about 5%. The method proposed in this paper can achieve an upgrade in three-dimensional temperature reconstruction effects for substations

enhancing the intelligent operational inspection capabilities of substations.
