# 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. |
|
|
|
|
