结构化布局 JSON:每个物体的三维坐标位置(x, y, z)和名称等,作为布局结果。</ol>The goal is to arrange the objects in a dinning room setting that includes a ,..., and respect the spatial constraints and user preferences. Here's how we can approach this:1. **Kitchen Island**: Place it centrally ...2. **Hanging Pot Rack**: Hang it above ......Let's compute the positions:- **Kitchen Island**: (3, 2.5, 0.45)- **Hanging Pot Rack**: (3, 2.5, 0.65)...Now, let's generate the JSON output.[{"new_object_id": "kitchen_island_1", "x": 3.0, "y": 2.5, "z": 0.45}, ......]
3. 在“RL-Before vs RL-After”的对比实验中,MetaSpatial 框架在提升模型三维空间推理能力方面的效果得到了清晰体现。强化学习训练前,模型生成的物体布局普遍混乱、错位,且常出现物体漂浮、重叠或放置在不符合物理规律的位置等问题。训练后,生成的布局则变得更加结构化、逼真,并且在语义上更加连贯,表现出更强的空间感知能力、物体对齐能力以及功能合理性。
