This repository contains the Spatial-Temporal Intelligence Benchmark (STI-Bench), introduced in the paper [“STI-Bench: Are MLLMs Ready for Precise Spatial-Temporal World Understanding?”](https://arxiv.org/abs/2503.23765), which evaluates the ability of Multimodal Large Language Models (MLLMs) to understand spatial-temporal concepts through real-world video data.

## Files



```bash

git lfs install
git clone https://huggingface.co/datasets/MIRA-SJTU/STI-Bench

```


## Dataset Description

STI-Bench evaluates MLLMs’ spatial-temporal understanding by testing their ability to estimate, predict, and understand object appearance, pose, displacement, and motion from video data. The benchmark contains more than 2,000 question-answer pairs across 300 videos, sourced from real-world environments such as desktop settings, indoor scenes, and outdoor scenarios. These videos are taken from datasets like Omni6DPose, ScanNet, and Waymo.

STI-Bench is designed to challenge models on both static and dynamic spatial-temporal tasks, including:

| Task Name | Description |
| :-------- | :---------- |
| **3D Video Grounding** | Locate the 3D bounding box of objects in the video |
| **Ego-Centric Orientation** | Estimate the camera's rotation angle |
| **Pose Estimation** | Determine the camera pose |
| **Dimensional Measurement** | Measure the length of objects |
| **Displacement & Path Length** | Estimate the distance traveled by objects or camera |
| **Speed & Acceleration** | Predict the speed and acceleration of moving objects or camera |
| **Spatial Relation** | Identify the relative positions of objects |
| **Trajectory Description** | Summarize the trajectory of moving objects or camera|

### Dataset Fields Explanation

The dataset contains the following fields, each with its respective description:

| Field Name        | Description |
| :---------------- | :---------- |
| **Video**         | The string corresponding to the video file. |
| **Source**        | The string corresponding to the video source, which can be "ScanNet," "Waymo," or "Omni6DPose." |
| **Task**          | The string representing the task type, e.g., "3D Video Grounding," "Ego-Centric Orientation," etc. |
| **QType**         | The string specifying the question type, typically a multiple-choice question. |
| **Question**      | The string containing the question presented to the model. |
| **Prompt**        | Additional information that might be helpful for answering the question, such as object descriptions. |
| **time_start**    | A float64 value indicating the start time of the question in the video (in seconds). |
| **time_end**      | A float64 value indicating the end time of the question in the video (in seconds). |
| **Candidates**    | A dictionary containing answer choices in the format `{"A": "value", "B": "value", ...}`. |
| **Answer**        | The string corresponding to the correct answer, represented by the choice label (e.g., "A", "B", etc.). |
| **Answer Detail** | A string representing the precise value or description of the correct answer. |
| **ID**            | A sequential ID for each question, unique within that video. |
| **Scene**         | The string describing the scene type of the video, such as "indoor," "outdoor," or "desktop." |

## Evaluation

STI-Bench evaluates performance using accuracy, calculated based on exact matches for multiple-choice questions. 

We provide an out-of-the-box evaluation of STI-Bench in our [GitHub repository](https://github.com/MIRA-SJTU/STI-Bench)

Note: STI-Bench is now supported by [EASI](https://github.com/EvolvingLMMs-Lab/EASI), an open-source evaluation tool for spatial intelligence.
