# 3D Object Grounding

> Accurate 3D bounding boxes for indoor and outdoor objects

Qwen3-VL introduces advanced 3D grounding capabilities, providing accurate 3D bounding boxes for both indoor and outdoor objects. This enables spatial reasoning and supports embodied AI applications.

## Capability Overview

The 3D grounding feature enables you to:

* Generate accurate 3D bounding boxes
* Handle both indoor and outdoor scenes
* Support spatial reasoning tasks
* Enable embodied AI applications
* Understand depth and spatial relationships
* Provide position, viewpoint, and occlusion information

## Example Usage

```python theme={null}
from transformers import AutoModelForImageTextToText, AutoProcessor

model = AutoModelForImageTextToText.from_pretrained(
    "Qwen/Qwen3-VL-235B-A22B-Instruct", dtype="auto", device_map="auto"
)
processor = AutoProcessor.from_pretrained("Qwen/Qwen3-VL-235B-A22B-Instruct")

messages = [
    {
        "role": "user",
        "content": [
            {
                "type": "image",
                "image": "path/to/scene.jpg",
            },
            {"type": "text", "text": "Provide 3D bounding boxes for the objects in this scene."},
        ],
    }
]

inputs = processor.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_dict=True,
    return_tensors="pt"
)
inputs = inputs.to(model.device)

generated_ids = model.generate(**inputs, max_new_tokens=512)
generated_ids_trimmed = [
    out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
    generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)
```
