RGBD Datasets

Each of the following datasets contain a series of RGB and depth images of a planar scene. In each dataset, the camera performs a distinct movement.

The images were captured using a Kinect camera and have a resolution of 1280×960 (the depth images are upscaled). They were generated using the ROS-based rgbd_dataset_gen toolkit.

The data sets are 'downwards compatible' to the image datasets created by Mikolajczyk et. al.

Data description

Each directory contains the following files:

  • depth*.pgm: 16-Bit depth images in mm
  • img*.pgm: 8-Bit RGB images
  • mask.pgm: Indicates region of interest in first image
  • H1to*p: 3×3 Homography from image 1 to n
  • K: 3×3 intrinsic camera matrix

In addition, it contains one of the following parameter files:

  • cam_rotation: rotation around camera axis (degrees)
  • vp_rotation: rotation around plane normal (degrees)
  • vp_angle: angle between camera axis and plane normal, relative to img1 (degrees)
  • scaling: 2d image scaling relative to first image (0..1)

The parameter files contain the numerical values for all images except the first.

The 'Poster' Data Set

Download the full dataset: poster.tar.gz (623 MB)

This scene shows several posters fixed to the ground or wall.

It contains the following transformations:

  • camrotate0,camrotate45,camrotate60: The camera rotates up to 90° around its view axis, while looking at the posters in a fronto-parallel view or 45°/60° tilted to the side.

  • scale: The camera moves away from the scene, resulting in a scaling effect down to 24%.

  • vpangle0, vpangle22, vpangle45: The camera starts at a fronto-parallel view, tilting to the side relative to the plane. The optical tilt axis is at 0, 22 and 45 degrees.

  • vprotate35,vprotate40,vprotate45,vprotate55: The camera is tilted 35°/40°/45°/55° relative to the plane and rotates around its normal.

The 'World Map' Data Set

Download the full dataset: world_map.tar.gz (623 MB)

This scene shows a world map fixed to a wall.

It contains the following transformations:

  • camrotate0,camrotate22,camrotate45: The camera rotates up to 90° around its view axis, while looking at the posters in a fronto-parallel view or 22°/45° tilted to the side.

  • scale: The camera moves away from the scene, resulting in a scaling effect down to 27%.

  • vpangle0, vpangle22, vpangle45: The camera starts at a fronto-parallel view, tilting to the side relative to the plane. The optical tilt axis is at 0, 22 and 45 degrees.
