New framework learns to select optimal views for 3D visual grounding

By PulseAugur Editorial · [1 sources] ·

Researchers have developed IVSGround, a new framework designed to improve 3D visual grounding by learning to select the most influential camera views for vision-language models (VLMs). Unlike previous methods that use fixed heuristics, IVSGround trains a lightweight view selector to identify views offering discriminative evidence for grounding. This approach utilizes a two-stage rejection sampling process with feedback from a reasoning VLM to generate supervision signals. Experiments on ScanRefer and NR3D datasets demonstrate that IVSGround enhances grounding accuracy compared to existing zero-shot pipelines, highlighting the importance of strategic view selection.

    Where to Look Matters: Learning Influential Views for VLM-based 3D Visual Grounding

    arXiv:2609.04741v1 Announce Type: new Abstract: Recent zero-shot 3D visual grounding methods leverage vision-language models (VLMs) to localize objects in 3D scenes from natural language queries. However, these methods typically rely on heuristic rules to select which camera view…
