Millimeter-level 3D Reconstruction Method of Power Equipment Based on Visible-light Gaussian Splatting
摘要
Abstract
To achieve millimeter-level 3D reconstruction of complex electrical equipment in substations,this paper pro-poses a 3D Gaussian Splatting modeling method that integrates feature enhancement with dynamic resolution control.The supervised contrastive learning and structural enhancement modules are introduced into the method,significantly im-proving feature recognition capabilities in weakly textured and repetitive structural regions.Meanwhile,an adaptive resolution control strategy is designed in the training phase,enabling efficient unified modeling of global structure and local details.Through comparative experiments with multi-view stereo(MVS),neural radiance field(NeRF),and the original 3D Gaussian splatting(3DGS)on a self-built multi-view visible light image dataset,the proposed method demonstrates significant advantages in reconstruction metrics including peak signal-to-noise ratio(PSNR),structural sim-ilarity index measure(SSIM),and L1 norm.The average L1 error is reduced to 0.033,enabling precise restoration of millimeter-level structural details and exhibiting strong engineering applicability.关键词
