+# DA-2K Evaluation Benchmark
+
+## Introduction
+
+![DA-2K](assets/DA-2K.png)
+
+DA-2K is proposed in [Depth Anything V2](https://depth-anything-v2.github.io) to evaluate the relative depth estimation capability. It encompasses eight representative scenarios of `indoor`, `outdoor`, `non_real`, `transparent_reflective`, `adverse_style`, `aerial`, `underwater`, and `object`. It consists of 1K diverse high-quality images and 2K precise pair-wise relative depth annotations.
+
+Please refer to our [paper](https://depth-anything-v2.github.io) for details in constructing this benchmark.
+
+
+## Usage
+
+Please first [download the benchmark]().
+
+All annotations are stored in [annotations.json](./annotations.json). The annotation file is a JSON object where each key is the path to an image file, and the value is a list of annotations associated with that image. Each annotation describes two points and identifies which point is closer to the camera. The structure is detailed below:
+
+```
+{
+  "image_path": [
+    {
+      "point1": [h1, w1], # (vertical position, horizontal position)
+      "point2": [h2, w2], # (vertical position, horizontal position)
+      "closer_point": "point1" # we always set "point1" as the closer one
+    },
+    ...
+  ],
+  ...
+}
+```
+
+To visualize the annotations:
+```bash
+python visualize.py [--scene-type <type>]
+```
+
+**Options**
+- `--scene-type <type>` (optional): Specify the scene type (`indoor`, `outdoor`, `non_real`, `transparent_reflective`, `adverse_style`, `aerial`, `underwater`, and `object`). Skip this argument or set <type> as `""` to include all scene types.
