Our datasets are hosted by OpenDataLab.

OpenDataLab is a pioneering open data platform for the large AI model era, making datasets accessible. By using OpenDataLab, researchers can obtain free formatted datasets in various fields.

Kindly refer to DATA_PREPARE.md for the details to prepare the ¹KITTI, ²KITTI-C, ³NYUDepth2, ⁴NYUDepth2-C, ⁵Cityscapes, ⁶Foggy-Cityscapes, ⁷nuScenes, and ⁸nuScenes-C, datasets.

Kindly refer to this page for the details to prepare the training and evaluation data associated with the 1st RoboDepth Competition at the 40th IEEE Conference on Robotics and Automation (ICRA 2023).

Kindly refer to GET_STARTED.md to learn more usage about this codebase.

📊 Metrics: The following metrics are consistently used in our benchmark:

• Absolute Relative Difference (the lower the better): $\text{Abs Rel} = \frac{1}{|D|}\sum_{pred\in D}\frac{|gt - pred|}{gt}$ .

• Accuracy (the higher the better): $\delta_t = \frac{1}{|D|}|{\ pred\in D | \max{(\frac{gt}{pred}, \frac{pred}{gt})< 1.25^t}}| \times 100\%$ .

• Depth Estimation Error (the lower the better):

  • $\text{DEE}_1 = \text{Abs Rel} - \delta_1 + 1$ ;
  • $\text{DEE}_2 = \frac{\text{Abs Rel} - \delta_1 + 1}{2}$ ;
  • $\text{DEE}_3 = \frac{\text{Abs Rel}}{\delta_1}$ .

• The second Depth Estimation Error term ($\text{DEE}_2$) is adopted as the main indicator for evaluating model performance in our RoboDepth benchmark. The following two metrics are adopted to compare between models' robustness:

  • mCE (the lower the better): The average corruption error (in percentage) of a candidate model compared to the baseline, which is calculated among all corruption types across five severity levels.
  • mRR (the higher the better): The average resilience rate (in percentage) of a candidate model compared to its "clean" performance, which is calculated among all corruption types across five severity levels.

⚙️ Notation: Symbol ^⭐ denotes the baseline model adopted in mCE calculation.

For more detailed benchmarking results and to access the pretrained weights used in robustness evaluation, kindly refer to RESULT.md.

You can manage to create your own "RoboDepth" corruption sets! Follow the instructions listed in CREATE.md.

• Initial release. 🚀
• Add scripts for creating common corruptions.
• Add download link of KITTI-C and NYUDepth2-C.
• Add competition data.
• Add benchmarking results.
• Add evaluation scripts on corruption sets.
