Key Points

To develop an accurate 3D scene reconstruction pipeline from sparse, uncalibrated camera views tailored for industrial digital twin applications.
Coupled explicit 3D Gaussian splatting with the DUSt3R model for uncalibrated end-to-end camera pose estimation.
Integrated Segment Anything Model 2 (SAM2) for hierarchical semantic scene decomposition to mitigate industrial occlusions.
Extracted lightweight meshes using a probability density field-driven algorithm and tested on the MipNeRF360 benchmark alongside an industrial dataset.
Achieved substantial qualitative and quantitative improvements in structural similarity index measure (SSIM) across sparse-view benchmarks.
Successfully extracted lightweight, surface-accurate geometric meshes directly from optimized Gaussian point clouds under heavy occlusions.
