Technical Summary Video

AirSim360, a simulation platform for omnidirectional data from aerial viewpoints, enabling wide-ranging scene sampling with drones. Specifically, AirSim360 focuses on three key aspects: a render-aligned data and labeling paradigm for pixel-level geometric, semantic, and instance-level understanding; an interactive pedestrian-aware system for modeling human behavior; and an automated trajectory generation paradigm to support navigation tasks.

AirSim360 Architecture

AirSim360 is a large-scale omnidirectional simulation platform for drone scenarios. we emphasize consistency and compatibility among three key components in low-altitude ground environments, including static surroundings, the UAV, and human actors, which aligns closely with the main characteristics of the human-centric real world.

Datasets Collection

To serve diverse research objectives, Omni360-X is organized into three subsets, including Scene, Pedestrian, and Trajectory, where each emphasizes a specific aspect of 360-degree understanding. Gaps figure Gaps figure

Experiments

We present and benchmark the sampled dataset in multiple tasks, indicating the benefits of our proposed simulator for real-world scenarios. Our simulated data consistently improves performance and robustness when evaluated on public real-world validation sets.

1. Monocular Pedestrian Distance Estimation (MPDE)

Training with the Omni360-Human dataset significantly improves the cross-domain generalization of Monocular Pedestrian Distance Estimation (MPDE) models. Specifically, the average angular error decreases from 21.21° to 17.02°, and the mean distance error decreases from 0.484 m to 0.458 m on public test sets.

Training Set Test Set Dist. Err ↓ (m) Ang. Err ↓ (°)
nuScenes KITTI 0.822 31.50
nuScenes + Omni360 KITTI 0.809 31.20
nuScenes FreeMan 0.260 17.00
nuScenes + Omni360 FreeMan 0.228 11.60

2. Panoramic Depth Estimation (Out-of-Domain)

We conduct out-of-domain experiments to evaluate the generalization ability of the Omni360 dataset. Models trained on Omni360 show improved generalization to unseen environments (SphereCraft).

Experiment Type Training Data Test Data AbsRel ↓ RMSE ↓
Out-of-Domain Deep360 SphereCraft 8.2570 0.0566
Out-of-Domain Omni360 SphereCraft 5.4372 0.0435

3. Panoramic Segmentation

The introduction of our large-scale Omni360-Scene segmentation data provides substantial performance gains on the WildPASS validation set for pixel-level scene parsing.
