## Dataset Description

<!-- Provide a longer summary of what this dataset is. -->
We introduce **ViewSpatial-Bench**, a comprehensive benchmark with over 5,700 question-answer pairs across 1,000+ 3D scenes from ScanNet and MS-COCO validation sets. This benchmark evaluates VLMs' spatial localization capabilities from multiple perspectives, specifically testing both egocentric (camera) and allocentric (human subject) viewpoints across five distinct task types.

ViewSpatial-Bench addresses a critical gap: while VLMs excel at spatial reasoning from their own perspective, they struggle with perspective-taking—adopting another entity's spatial frame of reference—which is essential for embodied interaction and multi-agent collaboration.The figure below shows the construction pipeline and example demonstrations of our benchmark.

The dataset contains the following fields:
| Field Name | Description |
| :--------- | :---------- |
| `question_type` | Type of spatial reasoning task, includes 5 distinct categories for evaluating different spatial capabilities |
| `image_path` | Path to the source image, includes data from two sources: `scannetv2_val` (ScanNet validation set) and `val2017` (MS-COCO validation set) |
| `question` | The spatial reasoning question posed to the model |
| `answer` | The correct answer to the question |
| `choices` | Multiple choice options available for the question |

## Uses

**I. With HuggingFace datasets library.**
```py
from datasets import load_dataset
ds = load_dataset("lidingm/ViewSpatial-Bench")
```
**II. Evaluation using Open-Source Code.**

Evaluate using our open-source evaluation code available on Github.(Coming Soon)
```py
# Clone the repository
git clone https://github.com/lidingm/ViewSpatial-Bench.git
cd ViewSpatial-Bench

# Install dependencies
pip install -r requirements.txt

# Run evaluation
python evaluate.py --model_path your_model_path
```
You can configure the appropriate model parameters and evaluation settings according to the framework's requirements to obtain performance evaluation results on the ViewSpatial-Bench dataset.

## Benchamrk
We provide benchmark results for various open-source models as well as **GPT-4o** and **Gemini 2.0 Flash** on our benchmark. *More model evaluations will be added.*
