ComfyUI-ZipDepth

ComfyUI-ZipDepth

A simple implementation of ZipDepth monocular depth estimation for ComfyUI. Lightweight (6.1M params), fast zero-shot relative depth — runs on GPU or CPU.

Installation

cd ComfyUI/custom_nodes
git clone https://github.com/<you>/ComfyUI-ZipDepth.git

Restart ComfyUI. The zipdepth_base.pth checkpoint (~27 MB) auto-downloads from the official repo on first use if not already bundled.

Usage

Node: ZipDepth Estimate (category ZipDepth)

| Input | Type | Description | |---|---|---| | image | IMAGE | Input image(s) | | colormap | Combo | Colormap for depth_colormap (Spectral, Turbo, Inferno, Viridis, Magma) | | invert | BOOLEAN | Default: near = white, far = black. Enable to flip |

| Output | Type | Description | |---|---|---| | depth | IMAGE | Grayscale depth, min-max normalized per image (near = 1.0) | | depth_colormap | IMAGE | Colormapped depth visualization |

Images are resized to a shorter side of ~384px (multiple of 32) for the model, and the depth map is resized back to the input resolution.
