 360DVO is a deep learning-based omnidirectional visual odometry (OVO) framework. It introduces a distortion-aware spherical feature extractor (DAS-Feat) and an omnidirectional differentiable bundle adjustment (ODBA) module. This repository provides the real-world OVO benchmark introduced in the study to facilitate evaluation in realistic settings.

+## Details
+360DVO Dataset is a large-scale real-world OVO benchmark emphasizing practical challenges across diverse environments and motions. It includes 20 sequences (~1k frames each) and all images are standardized to 3840x1920 at 10 FPS. Pseudo ground truth is reconstructed via SfM software Agisoft Metashape.
+
+To facilitate rigorous evaluation, we partition the dataset into Easy and Hard subsets (10 each) by trajectory complexity and scene dynamics, from linear, static cases to aggressive rotations, lighting shifts, and dynamic occlusions.
