スペースポリシーから選択されたスペースポリシーの利点は最近、スペースポリシーの画像編集などの生成タスクを通じて評価されていますが、スペースポリシーから選択されたスペースポリシーの全体的な観測からスペースポリシーに一致した視点のスペースポリシーの言語ガイドの生成は未だに未だに研究されていません。我々は、スペースポリシーから生成されるスペースポリシーの基準であるMindViewを導入し、スペースポリシーの関係とリファレンスフレームフリークエストの1500個のサンプルを3つの室内データセットで解釈しました。その7つのタスクは、MindViewにおける空間改善のための実質的な基準を示しています:ジオメトリック

Abstract

Spatial intelligence has recently been assessed through generative tasks such as spatially grounded image editing, yet language-guided generation of spatially consistent views from partial multi-view observations remains underexplored. We introduce MindView, a benchmark for generative multi-view spatial intelligence with 1,500 samples from 513 scenes across three indoor datasets. Its seven tasks form two families: geometry-dominant tasks specify changes in camera position and orientation, while semantics-dominant tasks require inferring target viewpoints by grounding referred objects and interpreting spatial relations and reference-frame cues. Evaluation of eleven generators reveals substantial room for improvement on MindView. A paired context analysis further shows that all eleven generators obtain lower overall scores under the expanded context setting. These findings motivate us to investigate whether task-specific supervision can improve target-view generation and whether models can use additional multi-view evidence effectively. We therefore fine-tune BAGEL on the MindView training dataset, improving its overall score by 24.3 points and yielding gains across all seven MindView tasks. Beyond these generation gains, the fine-tuned model also yields higher scores on three spatial-understanding benchmarks without training on their annotations, suggesting that learning to generate spatially grounded views may benefit spatial understanding. To improve evidence utilization under expanded context, we propose MindCue, a training-free spatial evidence selector guided by a target-view hypothesis. MindCue reverses the drop in overall score under expanded context and outperforms the standard-context baseline. Overall, MindView provides a concrete testbed for generative multi-view spatial intelligence.
