| | # Infinigen Stereo Video Dataset (InfinigenSV) |
| |
|
| | ## Dataset Summary |
| |
|
| | **InfinigenSV** is a synthetic stereo video dataset constructed using the photorealistic 3D environment engine Infinigen. |
| | It contains high-resolution stereo video sequences across diverse natural outdoor scenes such as forests, mountains, rivers, and rocky terrains, |
| | simulating real-world complexity with controlled camera motion and lighting. |
| |
|
| | The dataset is designed to support research on stereo video matching, temporal consistency, and 3D scene understanding, especially under challenging conditions like textureless surfaces, fine geometry, and dynamic parallax. |
| |
|
| | Ground-truth depth maps, along with full camera intrinsics/extrinsics, are provided per frame. |
| |
|
| | ## Dataset Structure |
| |
|
| | The folder structure of the dataset is organized by scene categories and sequences: |
| |

| | ### Data Instances |
| |
|
| | Each data instance corresponds to a single stereo frame in a video sequence and includes the following fields: |
| |
|
| | | Field | Type | Description | |
