The method uses instance labels and confidence weights in a 3D Gaussian Splatting scene model to select views for cluttered static scenes with supplied object masks. It prioritizes uncertain regions and can focus views on a specified object. Whole-scene depth error is lower than information-based baselines in reported tests; targeted views improve reconstruction of selected objects, though outcomes vary.
Key insights
- Integrating instance-level semantic information directly into the 3DGS representation through object vectors significantly improves geometric accuracy and novel view synthesis, particularly for depth maps.
- Confidence-weighted information gain, which balances exploration and exploitation by prioritizing underexplored and semantically uncertain Gaussians, leads to more complete scene understanding and robust 3D reconstruction.
- Normalizing information gain across different rendering modalities (RGB, depth, object masks) allows for a more balanced and effective fusion of diverse information, enhancing overall view selection quality.
