shijianjian/ZDPShift
ZDPShift is a depth estimation model from shijianjian. Use it for the depth estimation task on the model card, and read the license before you ship it in a product. The card lists the license as mit.

ZDPShift weights — Disparity Has a Sign
Checkpoints for Disparity Has a Sign: Stereo Matching Beyond the Zero-Disparity Plane. Each backbone comes as a pair:
| Suffix | Meaning |
|---|---|
*_zs.pth | the publicly released checkpoint, unchanged (zero-shot baseline; cannot output negative disparity) |
*_ours.pth | the same backbone fine-tuned on horizontally translated SceneFlow only (no benchmark data, no new parameters); estimates signed disparity on both sides of the screen plane |
| Backbone | Files | Notes |
|---|---|---|
| FoundationStereo | fs_zs.pth, fs_ours.pth, fs_cfg.yaml | signed cost volume, d_neg=64, d_pos=192 |
| IGEV-Stereo | igev_zs.pth, igev_ours.pth | signed cost volume, d_neg=64, d_pos=192 |
| RAFT-Stereo | raft_zs.pth, raft_ours.pth | symmetric correlation range |
| StereoAnyVideo | sav_zs.pth, sav_ours.pth, video_depth_anything_vits.pth | the VDA file is the frozen monocular prior the model constructs |
| DynamicStereo | dynamic_zs.pth, dynamic_ours.pth | |
| BiDAStereo | bida_zs.pth, bida_ours.pth |
The ZDPShift benchmark itself is evaluation-only: none of these models has seen it. Code, evaluation scripts and the demo: https://github.com/shijianjian/ZDPShift · https://huggingface.co/spaces/shijianjian/ZDPShift · dataset: https://huggingface.co/datasets/shijianjian/ZDPShift
