| # 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 | |
| |-----------------|-----------|-------------------------------------------------------| |
| | `left` | RGB image | Left view of the stereo pair (720×1280×3) | |
| | `right` | RGB image | Right view of the stereo pair (720×1280×3) | |
| | `depth` | depth file | Depth in meters (720×1280×3) | |
| | `camview` | camera file | Camera intrinsics and extrinsics per frame | |
