In order to solve the problems of low resolution and blurred temperature distribution of infrared images of power equipment caused by hardware limitations, this paper proposes a lightweight super‐resolution method based on the MIA network. The reconstructed images have good subjective and objective results, and provide support for power system fault ...

A Point Cloud Recognition Method for Substation Equipment Based on Improved Point Transformer
A point cloud recognition method for substation equipment based on improved Point Transformer is proposed to address the issue of low accuracy in point cloud segmentation during multi‐target recognition. First, a new dot product and double random inter‐point attention mechanism embedding are created in the convolutional projection layer of the Point ...
