ORB: Omni-directional Reconstruction Backbone

ORB is a 360° panorama depth estimation model that predicts dense distance maps from equirectangular panoramas in a single forward pass.

Model Description

This model takes a 360° equirectangular panorama (2:1 aspect ratio) as input and outputs a dense depth/distance map at the same resolution. It's designed for:

Zero-shot depth estimation from panoramic images
Scale-invariant predictions with geometric fidelity
End-to-end processing without post-processing

Quick Start

python

from orb import predict_pano_depth

# Predict depth from panorama
distance = predict_pano_depth('panorama.png')

Model Details

Input: RGB panorama (equirectangular, width = 2 × height)
Output: Dense depth/distance map (same resolution as input)
Format: SafeTensors (1.3 GB)
Precision: FP32 / FP16 supported
Base Architecture: Built upon DA²: Depth Anything in Any Direction
