# LibreDepthAnything3l-depth

DA3MONO-LARGE ViT-L relative-depth weights converted for LibreYOLO's depth
task.

## Source

The architecture is derived from
[ByteDance-Seed/Depth-Anything-3](https://github.com/ByteDance-Seed/Depth-Anything-3)
at commit `41736238f5bced4debf3f2a12375d2466874866d`.
Copyright (c) 2025 ByteDance Ltd. and/or its affiliates. Licensed under the

Platforms' Apache-2.0 attribution.

The learned parameters come from
[depth-anything/DA3MONO-LARGE](https://huggingface.co/depth-anything/DA3MONO-LARGE)
at revision `f465978e618db8cc79c83b8bbf24964857db1875`, published under
Apache-2.0.

## Modifications

State-dict key remapping only: conversion removes the official high-level
API's outer `model.` prefix and wraps all 406 unchanged tensors in LibreYOLO
checkpoint schema v1.0. LibreYOLO reproduces the official mono sky handling
and maps the model's positive relative depth to relative inverse depth, where
higher means closer and no metric unit is implied.

See `weights/convert_depth_anything3_weights.py` in the
[LibreYOLO source repository](https://github.com/LibreYOLO/libreyolo).

## Usage

```python
from libreyolo import LibreYOLO

model = LibreYOLO("LibreDepthAnything3l-depth.pt")
result = model("image.jpg")[0]
inverse_depth = result.depth_map.data
```
