ComfyUI-UniDepth

ComfyUI nodes for UniDepthV2 — universal monocular metric depth estimation by Piccinelli et al. (ETH Zürich, CVPR 2024 + 2025 follow-up).

From a single RGB image, UniDepth predicts:

• Metric depth (meters)
• Camera intrinsics (or honours yours if you provide them)
• Per-pixel 3D point map (XYZ in camera space)
• Per-pixel ray directions
• Confidence map

Nodes

| Node | Purpose | |---|---| | UniDepthLoader | Load a UniDepth model (V2 ViT-S/B/L or V1 ViT-L / ConvNeXt-L). Auto-downloads from HuggingFace into ComfyUI/models/unidepth/. | | UniDepthInfer | Run inference. RGB image in → metric depth, points, intrinsics, rays, confidence. | | UniDepthCameraIntrinsics | Build a Pinhole 3×3 K from fx/fy/cx/cy (or fov + image size). | | UniDepthDepthPreview | Colorize raw metric depth to an IMAGE for visual inspection. | | UniDepthSavePointCloud | Save the per-pixel point map as a colored PLY. |
