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. AI
