| ### Changelog | |
| * [March 2021] Initial release of inference code and models | |
| ### Setup | |
| 1) Download the model weights and place them in the `weights` folder: | |
| Monodepth: | |
| - [dpt_hybrid-midas-501f0c75.pt](https://github.com/intel-isl/DPT/releases/download/1_0/dpt_hybrid-midas-501f0c75.pt), [Mirror](https://drive.google.com/file/d/1dgcJEYYw1F8qirXhZxgNK8dWWz_8gZBD/view?usp=sharing) | |
| - [dpt_large-midas-2f21e586.pt](https://github.com/intel-isl/DPT/releases/download/1_0/dpt_large-midas-2f21e586.pt), [Mirror](https://drive.google.com/file/d/1vnuhoMc6caF-buQQ4hK0CeiMk9SjwB-G/view?usp=sharing) | |
| Segmentation: | |
| - [dpt_hybrid-ade20k-53898607.pt](https://github.com/intel-isl/DPT/releases/download/1_0/dpt_hybrid-ade20k-53898607.pt), [Mirror](https://drive.google.com/file/d/1zKIAMbltJ3kpGLMh6wjsq65_k5XQ7_9m/view?usp=sharing) | |
| - [dpt_large-ade20k-b12dca68.pt](https://github.com/intel-isl/DPT/releases/download/1_0/dpt_large-ade20k-b12dca68.pt), [Mirror](https://drive.google.com/file/d/1foDpUM7CdS8Zl6GPdkrJaAOjskb7hHe-/view?usp=sharing) | |
| 2) Set up dependencies: | |
| ```shell | |
| pip install -r requirements.txt | |
| ``` | |
| The code was tested with Python 3.7, PyTorch 1.8.0, OpenCV 4.5.1, and timm 0.4.5 | |
| ### Usage | |
| 1) Place one or more input images in the folder `input`. | |
| 2) Run a monocular depth estimation model: | |
| ```shell | |
| python run_monodepth.py | |
| ``` | |
| Or run a semantic segmentation model: | |
| ```shell | |
| python run_segmentation.py | |
| ``` | |
| 3) The results are written to the folder `output_monodepth` and `output_semseg`, respectively. | |
| Use the flag `-t` to switch between different models. Possible options are `dpt_hybrid` (default) and `dpt_large`. | |
| **Additional models:** | |
| - Monodepth finetuned on KITTI: [dpt_hybrid_kitti-cb926ef4.pt](https://github.com/intel-isl/DPT/releases/download/1_0/dpt_hybrid_kitti-cb926ef4.pt) [Mirror](https://drive.google.com/file/d/1-oJpORoJEdxj4LTV-Pc17iB-smp-khcX/view?usp=sharing) | |
| - Monodepth finetuned on NYUv2: [dpt_hybrid_nyu-2ce69ec7.pt](https://github.com/intel-isl/DPT/releases/download/1_0/dpt_hybrid_nyu-2ce69ec7.pt) [Mirror](https\://drive.google.com/file/d/1NjiFw1Z9lUAfTPZu4uQ9gourVwvmd58O/view?usp=sharing) | |
| Run with | |
| ```shell | |
| python run_monodepth -t [dpt_hybrid_kitti|dpt_hybrid_nyu] | |
| ``` | |
