DA-2K Evaluation Benchmark

Introduction

DA-2K is proposed in Depth Anything V2 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 for details in constructing this benchmark.

Usage

Please first download the benchmark.

All annotations are stored in 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:

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 as "" to include all scene types.
